@@ -0,0 +1,291 @@
+### v8.0.0 (2022-03-22)
+
+* **BREAKING** Removed RUSageMeter.  This was used to get resource usage statistics via `libuv`. It is no longer needed since Node.js version 12 has support via `process.cpuUsage`.
+
+* Fixed spelling in compatibility documentation.
+
+* Added integration tests for downloading with proxy.
+
+* Fixed the download tests to skip when running on branch or unsupported architectures.
+
+### v7.1.2 (2022-02-23)
+
+* Added `windows-latest` run for Node 16 only back to CI.
+
+* Added clarifying language to agent impacts when the module fails to install to install script.
+  * Indicated which page the missing metrics impact.
+  * Added new blurb to failure as the initial message can be missed/skimmed-over when there is significant build process logging.
+  * Indicated it is safe to run in production.
+
+### v7.1.1 (2022-02-16)
+
+* Replaced usage of `proxy-agent` with `https-proxy-agent`.
+
+* Bumped `nan` to ^2.15.0.
+
+* Updated `add-to-board` to use org level `NODE_AGENT_GH_TOKEN`
+
+* Changed trigger on binary upload to wait for release of module instead of waiting for a tag that starts with `v` to be created
+
+* Updated CI workflow to use `windows-2019` image instead of `windows-latest`.
+
+### v7.1.0 (2022-01-11)
+
+* Added ability to download pre-builts through a proxy host.
+  * Use `NR_NATIVE_METRICS_PROXY_HOST=<proxy_host> npm i @newrelic/native-metrics`.
+
+* Fixed deprecated code, updated `fs.existsSync` to `fs.accessSync` and using `NULL` vs. the more modern `nullptr`.
+
+* Added workflow to automate preparing release notes by reusing the newrelic/node-newrelic/.github/workflows/prep-release.yml@main workflow from agent repository.
+
+* Added job to automatically add issues/pr to Node.js Engineering board
+
+### v7.0.2 (2021-08-26):
+
+* Updated code to only check `node-gyp` version when the module needs to be built to avoid hanging node and subsequently causing OOM errors.
+* Added a pre-commit hook to check if package.json changes and run `oss third-party manifest` and `oss third-party notices`. This will ensure the `third_party_manifest.json` and `THIRD_PARTY_NOTICES.md` are up to date.
+* Fixed intermittent timeout issue with the server smoke integration test.
+
+  Excluded native metric install setup time from server soak test timeout.
+* Added `@newrelic/eslint-config` to rely on a centralized eslint ruleset.
+* Added `husky` + `lint-staged` to run linting on all staged js files.
+* Added integration tests for pre-build and upload tasks.
+* Upgraded setup-node CI job to v2 and changed the linting node version to `lts/*` for future proofing.
+
+### v7.0.1 (2021-07-20):
+
+* Added support for Node 16.
+* **BREAKING** Removed support for Node 10.
+
+  The minimum supported version is now Node v12. For further information on our support policy, see: https://docs.newrelic.com/docs/agents/nodejs-agent/getting-started/compatibility-requirements-nodejs-agent.
+
+* Updated release workflow to run on Node v12.x, 14.x, and v16.x.
+* Added files list to package.json instead of relying on `.npmignore`.
+* Removed unused `bin/test-all-node.sh`.
+* Removed semver check for Resource Unit meter availability.
+* Fixed v7.0.0 by adding `binding.gyp` to package.json files list.
+
+### v7.0.0 (2021-07-20):
+
+* **This release has been deprecated.** Please use version 7.0.1 or higher.
+
+### v6.0.2 (2021-06-16):
+
+* Changes hasCalledBack from a constant to a variable to avoid failure when it gets reassigned.
+Thank you @paulgoertzen-merico for the bug fix.
+* Added 'no-const-assign' lint rule.
+
+### v6.0.1 (2021-06-15):
+
+* Created a standalone upload script to avoid issues where aws-sdk does not exist.
+* Bumped tap to ^15.0.9.
+* Replaced deprecated tap methods with preferred ones.
+* Updated CONTRIBUTING.md to reference the New Relic org wide Code of Conduct.
+* Added lib/upload.js to the .npmignore as it is not needed for the module to function.
+* Bumped nan to ^2.14.2.
+
+### v6.0.0 (2020-11-03):
+
+* Removed Node v8.x from ci.
+* Updated README to be consistent with OSS template.
+* Added open source policy workflow.
+* Supressing warnings during installation on alpine docker image.
+  Thank you @eyedean for the contribution.
+* Updated name and job-name in release workflow.
+* Filtered out tags for CI workflow to prevent running on tag push for releases. The release job handles full testing.
+
+### v5.3.0 (2020-08-06):
+
+* Updated to Apache 2.0 license.
+* Added third party notices file and metadata for dependencies.
+* Updated README with more detail.
+* Added issue templates for bugs and enhancements.
+* Added code of conduct file.
+* Updated contributing guide.
+* Added pull request template.
+* Migrated CI to GitHub Actions.
+* Added copyright headers to all source files.
+* Added additional items to .npmignore.
+
+### v5.2.0 (2020-06-01):
+
+* Added special binary naming case to enable usage in Electron environments.
+
+  Enables the module to be used in Electron environments when built with tools that add 'electron' to `npm_config_runtime` or `npm_config_disturl` (such as `electron-rebuild` or `electron-builder`). In this case, the ABI is left-off of the file name.
+
+  Many thanks to @frankrobert-ls for raising the issue and providing a patch!
+
+  Please Note: Electron is not officially supported and other issues may still exist with the module in these environments.
+
+### v5.1.0 (2020-05-06):
+
+* Upgraded `nan` to ^2.14.1 to resolve 'GetContents' deprecation warning with Node 14.
+
+  Includes addition of Node 14 coverage and builds. Many thanks to @abetomo for the contribution.
+
+### v5.0.0 (2019-10-16):
+
+* **BREAKING** Removed support for Node 6, 7, 9 and 11.
+
+  The minimum supported version of the native metrics module is now Node v8. For further information on our support policy, see: https://docs.newrelic.com/docs/agents/nodejs-agent/getting-started/compatibility-requirements-nodejs-agent.
+
+* Added support for Node v12.
+
+### v4.1.0 (2019-02-07):
+
+* Added support for insecure (http) binary hosts. Use at your own discretion.
+
+  The default host remains as New Relic's binary repository behind an `https`
+  server. To use an `http` endpoint you must manually configure it yourself.
+
+  Special thanks to Adam Brett (@adambrett) and Guilherme Nagatomo (@guilhermehn)
+  for contributing this feature.
+
+### v4.0.0 (2019-01-22):
+
+* **BREAKING**: Dropped support for Node versions <6.
+
+* Added pre-execution log message calling out that this is an optional
+  dependency in the agent.
+
+* Simplified final error by removing most of the confusing `Failed to...`
+  messages.
+
+### v3.1.2 (2018-10-22):
+
+* Corrected check for build flags to base on gyp version, not Node version.
+
+  Previously, when checking if the old `\t:` syntax should be used, this looked
+  for Node <10.8.0. Now this looks for node-gyp <3.7.0. This accounts for
+  situations where users install their own versions of node-gyp.
+
+  Special thanks to Eric Boureau (@eboureau) for contributing this fix.
+
+### v3.1.1 (2018-09-10):
+
+* Fixed building the module on Windows with Node v10.8.0 or greater.
+
+  Special thanks to Elmar Burke (@elmarburke) for this contribution!
+
+### v3.1.0 (2018-07-02):
+
+* Added support for caching prebuilt binaries for firewalled deployments.
+
+  Simply set the `NR_NATIVE_METRICS_DOWNLOAD_HOST` environment variable to the
+  protocol and host for the download (e.g. `http://your-internal-cache/`) and
+  `NR_NATIVE_METRICS_REMOTE_PATH` to the path to the download folder (e.g.
+  `path/to/downloads/folder`).
+
+  Special thanks to Adam Brett (@adambrett) for contributing this feature.
+
+* Added support and pre-built binaries for Node 10.
+
+### v3.0.0 (2018-06-04):
+
+* **BREAKING** Removed support for Node 0.12.
+
+  The minimum supported version of the native metrics module is now Node v4.
+
+* **BREAKING** Removed `gc` event in favor of `getGCMetrics()` method.
+
+  The `gc` event will no longer be emitted for each garbage collection by V8.
+  Instead, metrics for garbage collections are aggregated in C++ and can be
+  retrieved by calling `getGCMetrics()`. Like `getLoopMetrics()`, this new
+  method will reset the aggregated metrics.
+
+* Added pre-built binaries for Node 5 and 7.
+
+### v2.4.0 (2018-04-20):
+
+* Added `NR_NATIVE_METRICS_NO_BUILD` and `NR_NATIVE_METRICS_NO_DOWNLOAD`
+  environment variables.
+
+  These are just environment variable versions of the `--no-build` and
+  `--no-download` flags introduced in v2.3.0.
+
+### v2.3.0 (2018-04-19):
+
+* Added `--no-build` and `--no-download` flags for install script.
+
+  These flags prevent the installer for the native metrics from either building
+  or downloading binaries. If both are specified, `--no-download` is ignored.
+
+### v2.2.0 (2018-02-12):
+
+* The package will now pull down pre-built binaries if compilation fails.
+
+  After confirming that the binary downloading functionality works, the feature
+  has been enabled by default.  The installation script will still default to a
+  fresh build where possible, using the download option as a fall back.
+
+* The process will no longer be held open due to pending timers.
+
+  Previously, the timer used to calculate the CPU usage by a tick of the event
+  loop was left pending, causing the process to hang.
+
+
+### v2.1.2 (2017-09-26):
+
+* Metric timers no longer hold the process open.
+
+Thanks to @samshull for the contribution!
+
+### v2.1.1 (2017-04-03):
+
+* Fixed build error on Windows thanks to Maximilian Haupt (@0x7f).
+
+* Added C++-layer unit testing using [gtest](https://github.com/google/googletest).
+
+* Updated readme with correct installation for the New Relic Agent v1.
+
+### v2.1.0 (2017-02-06):
+
+* Added an event loop CPU usage metric.
+
+  The module will now report round trip CPU usage metrics for Node's event loop. This
+  metric can be read off with `nativeMetrics.getLoopMetrics()` and will
+  represent the amount of CPU time per tick of the event loop.
+
+### v2.0.2 (2017-01-19):
+
+* Removed pre-compiling binaries using the `node-pre-gyp` module.
+
+  Previously we provided pre-compiled binaries for certain platforms and versions of Node.
+  However, this caused issues for customers using shrinkwrapping.  In order to support
+  shrinkwrapping as well as all versions of Node and npm that our customers use, we have
+  decided to remove this feature.  This means that in order to use this module, users now
+  need to have a compiler on the machine where it is being installed.
+  See [node-gyp] (https://www.npmjs.com/package/node-gyp#installation) for more
+  information on compiling native addons.
+
+### v2.0.0 (2017-01-04):
+
+* Removed support for Node 0.10.
+
+  The `segfault-handler` dependency no longer compiles on Node 0.10 in our tests.
+
+* The `node-pre-gyp` module is now a bundled dependency.
+
+  Previously it was installed using a preinstall script, which was causing an issue with
+  shrinkwrapping parent projects.  Thanks to Robert Rossman (@Alaneor) for
+  the contribution!
+
+* Added License section to the Readme file.
+
+### v1.0.0 (2016-12-07):
+
+* General release. No code changes from v0.1.1.
+
+### v0.1.1 (2016-12-05):
+
+* Added guard against binding GC events more than once.
+
+* Removed OS X from Travis to temporarily get around extremely long builds.
+  Added script to run tests locally across multiple versions of Node.
+
+* Added test for checking licenses of dependencies.
+
+### v0.1.0 (2016-11-29):
+
+* Added `gc` event with duration and type of garbage collection.
+* Added `usage` event with current and diff of resource usage stats.

+
+## PR Guidelines
+
+### Version Support
+
+When contributing, keep in mind that New Relic customers (that's you!) are running many different versions of Node, some of them pretty old. Changes that depend on the newest version of Node will probably be rejected, especially if they replace something backwards compatible.
+
+Be aware that the instrumentation needs to work with a wide range of versions of the instrumented modules, and that code that looks nonsensical or overcomplicated may be that way for compatibility-related reasons. Read all the comments and check the related tests before deciding whether existing code is incorrect.
+
+If you’re planning on contributing a new feature or an otherwise complex contribution, we kindly ask you to start a conversation with the maintainer team by opening up an Github issue first.
+
+### General Guidelines
+
+In general, we try to limit adding third-party production dependencies. If one is necessary, please be prepared to make a clear case for the need.
+
+### Coding Style Guidelines/Conventions
+
+We use eslint to enforce certain coding standards. Please see our [.eslintrc](./.eslintrc.js) file for specific rule configuration.
+
+### Testing Guidelines
+
+The native metrics module includes a suite of unit and functional tests which should be used to
+verify your changes don't break existing functionality.
+
+All tests are stored in `tests/` and are written using
+[node-tap](https://www.npmjs.com/package/tap) with the extension `.tap.js`.
+
+#### Running Tests
+
+Running the test suite is simple. Just run:
+
+    npm test
+
+This will install all the necessary modules and run the unit tests in standalone mode, followed by
+the functional tests if all of the unit tests pass.
+
+To just run unit tests, run the following:
+
+    npm run unit
+
+#### Writing Tests
+
+For most contributions it is strongly recommended to add additional tests which
+exercise your changes. This helps us efficiently incorporate your changes into
+our mainline codebase and provides a safeguard that your change won't be broken
+by future development. Because of this, we require that all changes come with
+tests. You are welcome to submit pull requests with untested changes, but they
+won't be merged until you or the development team have an opportunity to write
+tests for them.
+
+There are some rare cases where code changes do not result in changed
+functionality (e.g. a performance optimization) and new tests are not required.
+In general, including tests with your pull request dramatically increases the
+chances it will be accepted.

+
+# Native Metrics for New Relic Node.js Agent [![native-metrics CI][ci-badge]][ci-link]
+
+This module provides hooks into the native layer of Node.js to provide metrics for
+the [New Relic Node.js Agent][npm-newrelic]. It gathers information that isn't
+available at the JS layer about the V8 virtual machine and the process health.
+It comes packaged with the New Relic Agent since v2, and there is nothing that
+needs to be done. For Agent v1 you need only to install the module alongside
+[`newrelic`][npm-newrelic].
+
+## Installation and Getting Started
+
+Typically, most users use the version auto-installed by the agent.
+
+In some cases, installing a specific version is ideal. For example, new features or major changes might be released via a major version update to this module, prior to inclusion in the main New Relic Node.js agent.
+
+```
+$ npm install --save @newrelic/native-metrics
+```
+
+Note that this is a native module and thus must be compiled to function.
+Pre-built binaries are provided for Linux servers running supported versions of
+Node. If you are not using Linux or not using a supported version of Node, you
+will need to have a compiler installed on the machine where this is to be
+deployed. See [node-gyp](https://www.npmjs.com/package/node-gyp#installation)
+for more information on compiling native addons.
+
+If you prepare and package deployments on one machine and install them on
+another, the two machines must have the same operating system and architecture.
+If they are not, you will need to re-build the native module after deploying in
+order to get the correct binaries.
+
+During installation, the module will first attempt build from source on the
+target machine. If that fails, it will attempt to download a pre-built binary
+for your system. You can disable the download attempt by setting
+`NR_NATIVE_METRICS_NO_DOWNLOAD` to `true` in your environment before
+installation.
+
+```sh
+$ export NR_NATIVE_METRICS_NO_DOWNLOAD=true
+$ npm install @newrelic/native-metrics
+```
+
+If you would like to skip the build step and only attempt to download a
+pre-build binary, set `NR_NATIVE_METRICS_NO_BUILD` to `true`.
+
+```sh
+$ export NR_NATIVE_METRICS_NO_BUILD=true
+$ npm install @newrelic/native-metrics
+```
+
+If both env vars are set, `NO_BUILD` will override `NO_DOWNLOAD`.
+
+If you are working behind a firewall and want to cache the downloads internally
+you can set the value of the download host and remote path instead of forcing a
+build:
+
+```sh
+$ export NR_NATIVE_METRICS_DOWNLOAD_HOST=http://your-internal-cache/
+$ export NR_NATIVE_METRICS_REMOTE_PATH=path/to/download/folder/
+$ npm install @newrelic/native-metrics
+```
+
+You can also specify a proxy host to route requests through using the `NR_NATIVE_METRICS_PROXY_HOST` environment variable:
+
+```sh
+$ export NR_NATIVE_METRICS_NO_BUILD=true
+$ export NR_NATIVE_METRICS_PROXY_HOST=http://your-proxy-host/
+$ npm install @newrelic/native-metrics
+```
+
+For more information, please see the agent [installation guide][install-node] and [compatibility and requirements][compatibility].
+
+## Usage
+
+```js
+var getMetricEmitter = require('@newrelic/native-metrics')
+
+var emitter = getMetricEmitter()
+if (emitter.gcEnabled) {
+  setInterval(() => {
+    var gcMetrics = emitter.getGCMetrics()
+    for (var type in gcMetrics) {
+      console.log('GC type name:', type)
+      console.log('GC type id:', gcMetrics[type].typeId)
+      console.log('GC metrics:', gcMetrics[type].metrics)
+    }
+  }, 1000)
+}
+if (emitter.usageEnabled) {
+  emitter.on('usage', (usage) => console.log(usage))
+}
+if (emitter.loopEnabled) {
+  setInterval(() => {
+    var loopMetrics = emitter.getLoopMetrics()
+    console.log('Total time:', loopMetrics.usage.total)
+    console.log('Min time:', loopMetrics.usage.min)
+    console.log('Max time:', loopMetrics.usage.max)
+    console.log('Sum of squares:', loopMetrics.usage.sumOfSquares)
+    console.log('Count:', loopMetrics.usage.count)
+  }, 1000)
+}
+```
+
+The metric emitter keeps a referenced timer running for its periodic sampling
+events. For a graceful shutdown of the process call `NativeMetricEmitter#unbind`.
+
+```js
+getMetricEmitter().unbind() // Process will now close gracefully.
+```
+
+If you would like to change the period of the sampling, simply unbind and then
+call `NativeMetricEmitter#bind` with the new period.
+
+```js
+var emitter = getMetricEmitter({timeout: 15000})
+emitter.unbind()
+emitter.bind(10000) // Samples will now fire once every 10 seconds.
+```
+
+## Testing
+
+This module includes a list of unit and functional tests.  To run these tests, use the following command
+
+    $ npm run test
+
+You may also run individual test suites with the following commands

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications

+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of

+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,

+# Node Compatibility Notes
+This document details issues specific to certain versions of node in regards to
+the native metrics module. It is a living document to be updated as new problems
+are found.
+
+### CPU Metrics
+Our native module relies on the function `uv_getrusage` to measure CPU usage.
+This function was added to libuv in [version 0.11.20][libuv 0.11.20] which was
+incorporated into Node in [version 0.11.12][node 0.11.12]. As of the time of
+this writing, both CPU measurements and loop timing require this function and
+thus can not be supported on earlier node versions.
+
+[libuv 0.11.20]: https://github.com/libuv/libuv/releases/tag/v0.11.20
+[node 0.11.12]: https://github.com/nodejs/node/releases/tag/v0.11.12

+# fsevents [![NPM](https://nodei.co/npm/fsevents.png)](https://nodei.co/npm/fsevents/)
+
+Native access to MacOS FSEvents in [Node.js](https://nodejs.org/)
+
+The FSEvents API in MacOS allows applications to register for notifications of
+changes to a given directory tree. It is a very fast and lightweight alternative
+to kqueue.
+
+This is a low-level library. For a cross-platform file watching module that
+uses fsevents, check out [Chokidar](https://github.com/paulmillr/chokidar).
+
+## Installation
+
+Supports only **Node.js v8.16 and higher**.
+
+```sh
+npm install fsevents
+```
+
+## Usage
+
+```js
+const fsevents = require('fsevents');
+const stop = fsevents.watch(__dirname, (path, flags, id) => {
+  const info = fsevents.getInfo(path, flags, id);
+}); // To start observation
+stop(); // To end observation
+```
+
+The callback passed as the second parameter to `.watch` get's called whenever the operating system detects a
+a change in the file system. It takes three arguments:
+
+###### `fsevents.watch(dirname: string, (path: string, flags: number, id: string) => void): () => Promise<undefined>`
+
+ * `path: string` - the item in the filesystem that have been changed
+ * `flags: number` - a numeric value describing what the change was
+ * `id: string` - an unique-id identifying this specific event
+
+ Returns closer callback which when called returns a Promise resolving when the watcher process has been shut down.
+
+###### `fsevents.getInfo(path: string, flags: number, id: string): FsEventInfo`
+
+The `getInfo` function takes the `path`, `flags` and `id` arguments and converts those parameters into a structure
+that is easier to digest to determine what the change was.
+
+The `FsEventsInfo` has the following shape:
+
+```js
+/**
+ * @typedef {'created'|'modified'|'deleted'|'moved'|'root-changed'|'cloned'|'unknown'} FsEventsEvent
+ * @typedef {'file'|'directory'|'symlink'} FsEventsType
+ */
+{
+  "event": "created", // {FsEventsEvent}
+  "path": "file.txt",
+  "type": "file",    // {FsEventsType}
+  "changes": {
+    "inode": true,   // Had iNode Meta-Information changed
+    "finder": false, // Had Finder Meta-Data changed
+    "access": false, // Had access permissions changed
+    "xattrs": false  // Had xAttributes changed
+  },
+  "flags": 0x100000000
+}
+```
+
+## Changelog
+
+- v2.3 supports Apple Silicon ARM CPUs
+- v2 supports node 8.16+ and reduces package size massively
+- v1.2.8 supports node 6+
+- v1.2.7 supports node 4+
+
+## Troubleshooting
+
+- I'm getting `EBADPLATFORM` `Unsupported platform for fsevents` error.
+- It's fine, nothing is broken. fsevents is macos-only. Other platforms are skipped. If you want to hide this warning, report a bug to NPM bugtracker asking them to hide ebadplatform warnings by default.

+
+Date.now() will only give you accuracy in milliseconds. This module calls
+`gettimeofday(2)` to get the time in microseconds and provides it in a few
+different formats. The same warning from that function applies:
+_The resolution of the system clock is hardware dependent, and the time may
+be updated continuously or in ``ticks.''_
+
+## N-API Support
+
+As of version `3.0.0`, this library is built using the [N-API](https://nodejs.org/api/n-api.html) library. This should allow you to upgrade to newer versions of Node.js without having to reinstall / rebuild this library.
+
+Version `3.0.0` and later also bundle prebuilt binaries for common systems in
+the npm package itself. These will be used if the version of Node you are using
+supports N-API ([>= v6.14.2](https://nodejs.org/api/n-api.html#n_api_n_api_version_matrix)), otherwise the binary will be recompiled on install.
+
+# Installation
+
+    npm install microtime
+
+# Usage
+
+### microtime.now()
+
+Get the current time in microseconds as an integer.
+
+### microtime.nowDouble()
+
+Get the current time in seconds as a floating point number with microsecond
+accuracy (similar to `time.time()` in Python and `Time.now.to_f` in Ruby).
+
+### microtime.nowStruct()
+
+Get the current time and return as a list with seconds and microseconds (matching the return value of `gettimeofday(2)`).
+
+# Example
+
+    > var microtime = require('microtime')
+    > microtime.now()
+    1297448895297028
+    > microtime.nowDouble()
+    1297448897.600976
+    > microtime.nowStruct()
+    [ 1297448902, 753875 ]
+
+## Estimating clock resolution
+
+Starting with version 0.1.3, there is a test script that tries to guess the clock resolution. You can run it with `npm test microtime`. Example output:
+
+    microtime.now() = 1298960083489806
+    microtime.nowDouble() = 1298960083.511521
+    microtime.nowStruct() = [ 1298960083, 511587 ]
+
+    Guessing clock resolution...
+    Clock resolution observed: 1us

+
+Thanks to the crazy changes in V8 (and some in Node core), keeping native addons compiling happily across versions, particularly 0.10 to 0.12 to 4.0, is a minor nightmare. The goal of this project is to store all logic necessary to develop native Node.js addons without having to inspect `NODE_MODULE_VERSION` and get yourself into a macro-tangle.
+
+This project also contains some helper utilities that make addon development a bit more pleasant.

+## News & Updates

+
+## Usage
+
+Simply add **NAN** as a dependency in the *package.json* of your Node addon:
+
+``` bash
+$ npm install --save nan
+```
+
+Pull in the path to **NAN** in your *binding.gyp* so that you can use `#include <nan.h>` in your *.cpp* files:
+
+``` python
+"include_dirs" : [
+    "<!(node -e \"require('nan')\")"
+]
+```
+
+This works like a `-I<path-to-NAN>` when compiling your addon.
+
+<a name="example"></a>
+
+## Example
+
+Just getting started with Nan? Take a look at the **[Node Add-on Examples](https://github.com/nodejs/node-addon-examples)**.
+
+Refer to a [quick-start **Nan** Boilerplate](https://github.com/fcanas/node-native-boilerplate) for a ready-to-go project that utilizes basic Nan functionality.
+
+For a simpler example, see the **[async pi estimation example](https://github.com/nodejs/nan/tree/master/examples/async_pi_estimate)** in the examples directory for full code and an explanation of what this Monte Carlo Pi estimation example does. Below are just some parts of the full example that illustrate the use of **NAN**.
+
+Yet another example is **[nan-example-eol](https://github.com/CodeCharmLtd/nan-example-eol)**. It shows newline detection implemented as a native addon.
+
+Also take a look at our comprehensive **[C++ test suite](https://github.com/nodejs/nan/tree/master/test/cpp)** which has a plethora of code snippets for your pasting pleasure.

+
+### JavaScript-accessible methods
+
+A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information.
+
+In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

+
+### Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="doc/scopes.md#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="doc/scopes.md#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection).
+
+### Persistent references
+
+An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
+
+Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://developers.google.com/v8/embed#handles).
+
+### New
+
+NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8.

+ - <a href="doc/new.md#api_nan_false"><b><code>Nan::False()</code></b></a>
+ - <a href="doc/new.md#api_nan_empty_string"><b><code>Nan::EmptyString()</code></b></a>
+
+
+### Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.
+
+ - <a href="doc/converters.md#api_nan_to"><b><code>Nan::To()</code></b></a>
+
+### Maybe Types
+
+The `Nan::MaybeLocal` and `Nan::Maybe` types are monads that encapsulate `v8::Local` handles that _may be empty_.

+### Script
+
+NAN provides `v8::Script` helpers as the API has changed over the supported versions of V8.

+ - <a href="doc/script.md#api_nan_run_script"><b><code>Nan::RunScript()</code></b></a>
+ - <a href="doc/script.md#api_nan_script_origin"><b><code>Nan::ScriptOrigin</code></b></a>
+
+
+### JSON
+
+The _JSON_ object provides the C++ versions of the methods offered by the `JSON` object in javascript. V8 exposes these methods via the `v8::JSON` object.
+
+ - <a href="doc/json.md#api_nan_json_parse"><b><code>Nan::JSON.Parse</code></b></a>
+ - <a href="doc/json.md#api_nan_json_stringify"><b><code>Nan::JSON.Stringify</code></b></a>
+
+Refer to the V8 JSON object in the [V8 documentation](https://v8docs.nodesource.com/node-8.16/da/d6f/classv8_1_1_j_s_o_n.html) for more information about these methods and their arguments.
+
+### Errors
+
+NAN includes helpers for creating, throwing and catching Errors as much of this functionality varies across the supported versions of V8 and must be abstracted.
+
+Note that an Error object is simply a specialized form of `v8::Value`.
+
+Also consult the V8 Embedders Guide section on [Exceptions](https://developers.google.com/v8/embed#exceptions) for more information.

+## Known issues
+
+### Compiling against Node.js 0.12 on OSX
+
+With new enough compilers available on OSX, the versions of V8 headers corresponding to Node.js 0.12
+do not compile anymore. The error looks something like:
+
+```
+❯   CXX(target) Release/obj.target/accessors/cpp/accessors.o
+In file included from ../cpp/accessors.cpp:9:
+In file included from ../../nan.h:51:
+In file included from /Users/ofrobots/.node-gyp/0.12.18/include/node/node.h:61:
+/Users/ofrobots/.node-gyp/0.12.18/include/node/v8.h:5800:54: error: 'CreateHandle' is a protected member of 'v8::HandleScope'
+  return Handle<T>(reinterpret_cast<T*>(HandleScope::CreateHandle(
+                                        ~~~~~~~~~~~~~^~~~~~~~~~~~
+```
+
+This can be worked around by patching your local versions of v8.h corresponding to Node 0.12 to make
+`v8::Handle` a friend of `v8::HandleScope`. Since neither Node.js not V8 support this release line anymore
+this patch cannot be released by either project in an official release.
+
+For this reason, we do not test against Node.js 0.12 on OSX in this project's CI. If you need to support
+that configuration, you will need to either get an older compiler, or apply a source patch to the version
+of V8 headers as a workaround.

+## Governance & Contributing
+
+NAN is governed by the [Node.js Addon API Working Group](https://github.com/nodejs/CTC/blob/master/WORKING_GROUPS.md#addon-api)
+
+### Addon API Working Group (WG)
+
+The NAN project is jointly governed by a Working Group which is responsible for high-level guidance of the project.
+
+Members of the WG are also known as Collaborators, there is no distinction between the two, unlike other Node.js projects.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project [README.md](./README.md#collaborators).
+
+Individuals making significant and valuable contributions are made members of the WG and given commit-access to the project. These individuals are identified by the WG and their addition to the WG is discussed via GitHub and requires unanimous consensus amongst those WG members participating in the discussion with a quorum of 50% of WG members required for acceptance of the vote.
+
+_Note:_ If you make a significant contribution and are not considered for commit-access log an issue or contact a WG member directly.
+
+For the current list of WG members / Collaborators, see the project [README.md](./README.md#collaborators).
+
+### Consensus Seeking Process
+
+The WG follows a [Consensus Seeking](https://en.wikipedia.org/wiki/Consensus-seeking_decision-making) decision making model.
+
+Modifications of the contents of the NAN repository are made on a collaborative basis. Anybody with a GitHub account may propose a modification via pull request and it will be considered by the WG. All pull requests must be reviewed and accepted by a WG member with sufficient expertise who is able to take full responsibility for the change. In the case of pull requests proposed by an existing WG member, an additional WG member is required for sign-off. Consensus should be sought if additional WG members participate and there is disagreement around a particular modification.
+
+If a change proposal cannot reach a consensus, a WG member can call for a vote amongst the members of the WG. Simple majority wins.

+## Asynchronous work helpers

+### Nan::AsyncWorker
+
+`Nan::AsyncWorker` is an _abstract_ class that you can subclass to have much of the annoying asynchronous queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the asynchronous work is in progress.
+
+This class internally handles the details of creating an [`AsyncResource`][AsyncResource], and running the callback in the
+correct async context. To be able to identify the async resources created by this class in async-hooks, provide a
+`resource_name` to the constructor. It is recommended that the module name be used as a prefix to the `resource_name` to avoid
+collisions in the names. For more details see [`AsyncResource`][AsyncResource] documentation.  The `resource_name` needs to stay valid for the lifetime of the worker instance.
+
+Definition:
+
+```c++
+class AsyncWorker {
+ public:
+  explicit AsyncWorker(Callback *callback_, const char* resource_name = "nan:AsyncWorker");
+
+  virtual ~AsyncWorker();
+
+  virtual void WorkComplete();
+
+  void SaveToPersistent(const char *key, const v8::Local<v8::Value> &value);
+
+  void SaveToPersistent(const v8::Local<v8::String> &key,
+                        const v8::Local<v8::Value> &value);
+
+  void SaveToPersistent(uint32_t index,
+                        const v8::Local<v8::Value> &value);

+### Nan::AsyncProgressWorkerBase &amp; Nan::AsyncProgressWorker
+
+`Nan::AsyncProgressWorkerBase` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
+
+Previously the definition of `Nan::AsyncProgressWorker` only allowed sending `const char` data. Now extending `Nan::AsyncProgressWorker` will yield an instance of the implicit `Nan::AsyncProgressWorkerBase` template with type `<char>` for compatibility.
+
+`Nan::AsyncProgressWorkerBase` &amp; `Nan::AsyncProgressWorker` is intended for best-effort delivery of nonessential progress messages, e.g. a progress bar.  The last event sent before the main thread is woken will be delivered.
+
+Definition:
+
+```c++
+template<class T>
+class AsyncProgressWorkerBase<T> : public AsyncWorker {
+ public:
+  explicit AsyncProgressWorkerBase(Callback *callback_, const char* resource_name = ...);
+
+  virtual ~AsyncProgressWorkerBase();

+### Nan::AsyncProgressQueueWorker
+
+`Nan::AsyncProgressQueueWorker` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
+
+`Nan::AsyncProgressQueueWorker` behaves exactly the same as `Nan::AsyncProgressWorker`, except all events are queued and delivered to the main thread.
+
+Definition:
+
+```c++
+template<class T>
+class AsyncProgressQueueWorker<T> : public AsyncWorker {
+ public:
+  explicit AsyncProgressQueueWorker(Callback *callback_, const char* resource_name = "nan:AsyncProgressQueueWorker");

+### Nan::AsyncQueueWorker
+
+`Nan::AsyncQueueWorker` will run a `Nan::AsyncWorker` asynchronously via libuv. Both the `execute` and `after_work` steps are taken care of for you. Most of the logic for this is embedded in `Nan::AsyncWorker`.

+
+Allocate a new `node::Buffer` object with the specified size and optional data. Calls `node::Buffer::New()`.
+
+Note that when creating a `Buffer` using `Nan::NewBuffer()` and an existing `char*`, it is assumed that the ownership of the pointer is being transferred to the new `Buffer` for management.
+When a `node::Buffer` instance is garbage collected and a `FreeCallback` has not been specified, `data` will be disposed of via a call to `free()`.
+You _must not_ free the memory space manually once you have created a `Buffer` in this way.

+## Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.

+
+A `Nan::MaybeLocal<T>` is a wrapper around [`v8::Local<T>`](https://v8docs.nodesource.com/node-8.16/de/deb/classv8_1_1_local.html) that enforces a check that determines whether the `v8::Local<T>` is empty before it can be used.
+
+If an API method returns a `Nan::MaybeLocal`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, an empty `Nan::MaybeLocal` is returned.

+## JavaScript-accessible methods
+
+A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information.
+
+In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

+### Nan::FunctionCallbackInfo
+
+`Nan::FunctionCallbackInfo` should be used in place of [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/node-8.16/dd/d0d/classv8_1_1_function_callback_info.html), even with older versions of Node where `v8::FunctionCallbackInfo` does not exist.
+
+Definition:
+
+```c++
+template<typename T> class FunctionCallbackInfo {
+ public:
+  ReturnValue<T> GetReturnValue() const;
+  v8::Local<v8::Function> Callee(); // NOTE: Not available in NodeJS >= 10.0.0
+  v8::Local<v8::Value> Data();
+  v8::Local<v8::Object> Holder();
+  bool IsConstructCall();
+  int Length() const;
+  v8::Local<v8::Value> operator[](int i) const;
+  v8::Local<v8::Object> This() const;
+  v8::Isolate *GetIsolate() const;
+};
+```
+
+See the [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/node-8.16/dd/d0d/classv8_1_1_function_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from methods.
+
+**Note:** `FunctionCallbackInfo::Callee` is removed in Node.js after `10.0.0` because it is was deprecated in V8. Consider using `info.Data()` to pass any information you need.
+
+<a name="api_nan_property_callback_info"></a>
+### Nan::PropertyCallbackInfo
+
+`Nan::PropertyCallbackInfo` should be used in place of [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d7/dc5/classv8_1_1_property_callback_info.html), even with older versions of Node where `v8::PropertyCallbackInfo` does not exist.
+
+Definition:
+
+```c++
+template<typename T> class PropertyCallbackInfo : public PropertyCallbackInfoBase<T> {
+ public:
+  ReturnValue<T> GetReturnValue() const;
+  v8::Isolate* GetIsolate() const;
+  v8::Local<v8::Value> Data() const;
+  v8::Local<v8::Object> This() const;
+  v8::Local<v8::Object> Holder() const;
+};
+```
+
+See the [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d7/dc5/classv8_1_1_property_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from property accessor methods.
+
+<a name="api_nan_return_value"></a>
+### Nan::ReturnValue
+
+`Nan::ReturnValue` is used in place of [`v8::ReturnValue`](https://v8docs.nodesource.com/node-8.16/da/da7/classv8_1_1_return_value.html) on both [`Nan::FunctionCallbackInfo`](#api_nan_function_callback_info) and [`Nan::PropertyCallbackInfo`](#api_nan_property_callback_info) as the return type of `GetReturnValue()`.
+
+Example usage:
+
+```c++
+void EmptyArray(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  info.GetReturnValue().Set(Nan::New<v8::Array>());
+}
+```
+
+Definition:
+
+```c++
+template<typename T> class ReturnValue {
+ public:
+  // Handle setters
+  template <typename S> void Set(const v8::Local<S> &handle);
+  template <typename S> void Set(const Nan::Global<S> &handle);
+
+  // Fast primitive setters
+  void Set(bool value);
+  void Set(double i);
+  void Set(int32_t i);
+  void Set(uint32_t i);
+
+  // Fast JS primitive setters
+  void SetNull();
+  void SetUndefined();
+  void SetEmptyString();
+
+  // Convenience getter for isolate
+  v8::Isolate *GetIsolate() const;
+};
+```
+
+See the documentation on [`v8::ReturnValue`](https://v8docs.nodesource.com/node-8.16/da/da7/classv8_1_1_return_value.html) for further information on this.
+
+<a name="api_nan_method"></a>
+### Method declaration
+
+JavaScript-accessible methods should be declared with the following signature to form a `Nan::FunctionCallback`:
+
+```c++
+typedef void(*FunctionCallback)(const FunctionCallbackInfo<v8::Value>&);
+```
+
+Example:
+
+```c++
+void MethodName(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  ...
+}
+```
+
+You do not need to declare a new `HandleScope` within a method as one is implicitly created for you.
+
+**Example usage**
+
+```c++
+// .h:
+class Foo : public Nan::ObjectWrap {
+  ...
+
+  static void Bar(const Nan::FunctionCallbackInfo<v8::Value>& info);
+  static void Baz(const Nan::FunctionCallbackInfo<v8::Value>& info);
+}
+
+
+// .cc:
+void Foo::Bar(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  ...
+}
+
+void Foo::Baz(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  ...
+}
+```
+
+A helper macro `NAN_METHOD(methodname)` exists, compatible with NAN v1 method declarations.
+
+**Example usage with `NAN_METHOD(methodname)`**
+
+```c++
+// .h:
+class Foo : public Nan::ObjectWrap {
+  ...
+
+  static NAN_METHOD(Bar);
+  static NAN_METHOD(Baz);
+}
+
+
+// .cc:
+NAN_METHOD(Foo::Bar) {
+  ...
+}
+
+NAN_METHOD(Foo::Baz) {
+  ...
+}
+```
+
+Use [`Nan::SetPrototypeMethod`](#api_nan_set_prototype_method) to attach a method to a JavaScript function prototype or [`Nan::SetMethod`](#api_nan_set_method) to attach a method directly on a JavaScript object.

+                const Nan::PropertyCallbackInfo<v8::Value>& info) {
+  ...
+}
+```
+
+You do not need to declare a new `HandleScope` within a getter as one is implicitly created for you.
+
+A helper macro `NAN_GETTER(methodname)` exists, compatible with NAN v1 method declarations.

+                              const PropertyCallbackInfo<void>&);
+```
+

+### Nan::New()
+
+`Nan::New()` should be used to instantiate new JavaScript objects.
+
+Refer to the specific V8 type in the [V8 documentation](https://v8docs.nodesource.com/node-8.16/d1/d83/classv8_1_1_data.html) for information on the types of arguments required for instantiation.
+
+Signatures:
+
+Return types are mostly omitted from the signatures for simplicity. In most cases the type will be contained within a `v8::Local<T>`. The following types will be contained within a `Nan::MaybeLocal<T>`: `v8::String`, `v8::Date`, `v8::RegExp`, `v8::Script`, `v8::UnboundScript`.
+
+Empty objects:
+
+```c++
+Nan::New<T>();
+```
+
+Generic single and multiple-argument:
+
+```c++
+Nan::New<T>(A0 arg0);
+Nan::New<T>(A0 arg0, A1 arg1);
+Nan::New<T>(A0 arg0, A1 arg1, A2 arg2);
+Nan::New<T>(A0 arg0, A1 arg1, A2 arg2, A3 arg3);
+```
+
+For creating `v8::FunctionTemplate` and `v8::Function` objects:
+
+_The definition of `Nan::FunctionCallback` can be found in the [Method declaration](./methods.md#api_nan_method) documentation._
+
+```c++
+Nan::New<T>(Nan::FunctionCallback callback,
+            v8::Local<v8::Value> data = v8::Local<v8::Value>());
+Nan::New<T>(Nan::FunctionCallback callback,
+            v8::Local<v8::Value> data = v8::Local<v8::Value>(),
+            A2 a2 = A2());
+```
+
+Native number types:
+
+```c++
+v8::Local<v8::Boolean> Nan::New<T>(bool value);
+v8::Local<v8::Int32> Nan::New<T>(int32_t value);
+v8::Local<v8::Uint32> Nan::New<T>(uint32_t value);
+v8::Local<v8::Number> Nan::New<T>(double value);
+```
+
+String types:
+
+```c++
+Nan::MaybeLocal<v8::String> Nan::New<T>(std::string const& value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const char * value, int length);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const char * value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const uint16_t * value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const uint16_t * value, int length);
+```
+
+Specialized types:
+
+```c++
+v8::Local<v8::String> Nan::New<T>(v8::String::ExternalStringResource * value);
+v8::Local<v8::String> Nan::New<T>(Nan::ExternalOneByteStringResource * value);
+v8::Local<v8::RegExp> Nan::New<T>(v8::Local<v8::String> pattern, v8::RegExp::Flags flags);
+```
+
+Note that `Nan::ExternalOneByteStringResource` maps to [`v8::String::ExternalOneByteStringResource`](https://v8docs.nodesource.com/node-8.16/d9/db3/classv8_1_1_string_1_1_external_one_byte_string_resource.html), and `v8::String::ExternalAsciiStringResource` in older versions of V8.

+
+<a name="api_nan_asyncresource"></a>
+### Nan::AsyncResource
+
+This class is analogous to the `AsyncResource` JavaScript class exposed by Node's [async_hooks][] API.
+
+When calling back into JavaScript asynchronously, special care must be taken to ensure that the runtime can properly track
+async hops. `Nan::AsyncResource` is a class that provides an RAII wrapper around `node::EmitAsyncInit`, `node::EmitAsyncDestroy`,
+and `node::MakeCallback`. Using this mechanism to call back into JavaScript, as opposed to `Nan::MakeCallback` or
+`v8::Function::Call` ensures that the callback is executed in the correct async context. This ensures that async mechanisms
+such as domains and [async_hooks][] function correctly.
+
+Definition:
+
+```c++
+class AsyncResource {
+ public:
+  AsyncResource(v8::Local<v8::String> name,
+                v8::Local<v8::Object> resource = New<v8::Object>());
+  AsyncResource(const char* name,
+                v8::Local<v8::Object> resource = New<v8::Object>());
+  ~AsyncResource();
+
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            v8::Local<v8::Function> func,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            v8::Local<v8::String> symbol,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            const char* method,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+};
+```
+
+* `name`: Identifier for the kind of resource that is being provided for diagnostics information exposed by the [async_hooks][]
+  API. This will be passed to the possible `init` hook as the `type`. To avoid name collisions with other modules we recommend
+  that the name include the name of the owning module as a prefix. For example `mysql` module could use something like
+  `mysql:batch-db-query-resource`.
+* `resource`: An optional object associated with the async work that will be passed to the possible [async_hooks][]
+  `init` hook. If this parameter is omitted, or an empty handle is provided, this object will be created automatically.
+* When calling JS on behalf of this resource, one can use `runInAsyncScope`. This will ensure that the callback runs in the
+  correct async execution context.
+* `AsyncDestroy` is automatically called when an AsyncResource object is destroyed.
+
+For more details, see the Node [async_hooks][] documentation. You might also want to take a look at the documentation for the
+[N-API counterpart][napi]. For example usage, see the `asyncresource.cpp` example in the `test/cpp` directory.
+
+<a name="api_nan_make_callback"></a>
+### Nan::MakeCallback()
+
+Deprecated wrappers around the legacy `node::MakeCallback()` APIs. Node.js 10+
+has deprecated these legacy APIs as they do not provide a mechanism to preserve
+async context.
+
+We recommend that you use the `AsyncResource` class and `AsyncResource::runInAsyncScope` instead of using `Nan::MakeCallback` or
+`v8::Function#Call()` directly. `AsyncResource` properly takes care of running the callback in the correct async execution
+context – something that is essential for functionality like domains, async_hooks and async debugging.

+### This vs. Holder
+
+When calling `Unwrap`, it is important that the argument is indeed some JavaScript object which got wrapped by a `Wrap` call for this class or any derived class.
+The `Signature` installed by [`Nan::SetPrototypeMethod()`](methods.md#api_nan_set_prototype_method) does ensure that `info.Holder()` is just such an instance.
+In Node 0.12 and later, `info.This()` will also be of such a type, since otherwise the invocation will get rejected.
+However, in Node 0.10 and before it was possible to invoke a method on a JavaScript object which just had the extension type in its prototype chain.
+In such a situation, calling `Unwrap` on `info.This()` will likely lead to a failed assertion causing a crash, but could lead to even more serious corruption.
+
+On the other hand, calling `Unwrap` in an [accessor](methods.md#api_nan_set_accessor) should not use `Holder()` if the accessor is defined on the prototype.
+So either define your accessors on the instance template,
+or use `This()` after verifying that it is indeed a valid object.
+
+### Examples
+
+#### Basic
+
+```c++
+class MyObject : public Nan::ObjectWrap {
+ public:
+  static NAN_MODULE_INIT(Init) {
+    v8::Local<v8::FunctionTemplate> tpl = Nan::New<v8::FunctionTemplate>(New);

+
+    constructor().Reset(Nan::GetFunction(tpl).ToLocalChecked());
+    Nan::Set(target, Nan::New("MyObject").ToLocalChecked(),

+    return my_constructor;
+  }
+
+  double value_;
+};
+
+NODE_MODULE(objectwrapper, MyObject::Init)

+## Persistent references
+
+An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
+
+Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

+
+`Nan::WeakCallbackInfo` is used as an argument when setting a persistent reference as weak. You may need to free any external resources attached to the object. It is a mirror of `v8:WeakCallbackInfo` as found in newer versions of V8.

+### Nan::WeakCallbackType
+
+Represents the type of a weak callback.
+A weak callback of type `kParameter` makes the supplied parameter to `Nan::PersistentBase::SetWeak` available through `WeakCallbackInfo::GetParameter`.
+A weak callback of type `kInternalFields` uses up to two internal fields at indices 0 and 1 on the `Nan::PersistentBase<v8::Object>` being made weak.
+Note that only `v8::Object`s and derivatives can have internal fields.

+## Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection).
+
+<a name="api_nan_handle_scope"></a>
+### Nan::HandleScope
+
+A simple wrapper around [`v8::HandleScope`](https://v8docs.nodesource.com/node-8.16/d3/d95/classv8_1_1_handle_scope.html).
+
+Definition:
+
+```c++
+class Nan::HandleScope {
+ public:
+  Nan::HandleScope();
+  static int NumberOfHandles();
+};
+```
+
+Allocate a new `Nan::HandleScope` whenever you are creating new V8 JavaScript objects. Note that an implicit `HandleScope` is created for you on JavaScript-accessible methods so you do not need to insert one yourself.
+
+Example:
+
+```c++
+// new object is created, it needs a new scope:
+void Pointless() {
+  Nan::HandleScope scope;
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+
+// JavaScript-accessible method already has a HandleScope
+NAN_METHOD(Pointless2) {
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+```
+
+<a name="api_nan_escapable_handle_scope"></a>
+### Nan::EscapableHandleScope
+
+Similar to [`Nan::HandleScope`](#api_nan_handle_scope) but should be used in cases where a function needs to return a V8 JavaScript type that has been created within it.
+
+Definition:
+
+```c++
+class Nan::EscapableHandleScope {
+ public:
+  Nan::EscapableHandleScope();
+  static int NumberOfHandles();
+  template<typename T> v8::Local<T> Escape(v8::Local<T> value);
+}
+```
+
+Use `Escape(value)` to return the object.
+
+Example:
+
+```c++
+v8::Local<v8::Object> EmptyObj() {
+  Nan::EscapableHandleScope scope;
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+  return scope.Escape(obj);

+### Nan::TypedArrayContents<T>
+
+A helper class for accessing the contents of an ArrayBufferView (aka a typedarray) from C++.  If the input array is not a valid typedarray, then the data pointer of TypedArrayContents will default to `NULL` and the length will be 0.  If the data pointer is not compatible with the alignment requirements of type, an assertion error will fail.
+
+Note that you must store a reference to the `array` object while you are accessing its contents.
