Change the behaviour where not passing attribs to the update API
overwrites the attribs with empty values. This commit changes the
behaviour so that in the absence of the attribs field in the
subscriber API, the existing value in the DB is retained.
The earlier approach of loading `/api/config.js` as a script on
initial page load with the necessary variables to init the UI is
ditched. Instead, it's now `/api/config` and `/api/settings` like
all other API calls. On load of the frontend, these two resources
are fetched and the frontend is initialised.
In addition to generating HTML forms for selected public lists,
the form page now shows a URL (/subscription/form) that can be
publicly shared to solicit subscriptions. The page lists all
public lists in the database. This page can be disabled on the
Settings UI.
This commit removes the Go html2text lib that would automatically
convert all HTML messages to plaintext and add them as the alt
text body to outgoing e-mails. This lib also had memory leak
issues with certain kinds of HTML templates.
A new UI field for optionally adding an alt plaintext body to
a campaign is added. On enabling, it converts the HTML message in
the campaign editor into plaintext (using the textversionjs lib).
This introduces breaking changes in the campaigns table schema,
model, and template compilation.
... instead of Vue.prototype variables which is the idiomatic
approach. Also, the refactor enables utils to be instantiated
as a class that takes the i18n object for util functions to have
accesss to i18n translation.
Certain SMTP hosts limit the total number of messages that can be
sent within a window, for instance, X / 24 hours. The concurrency
and message rate controls can only limit that to a max of
1 messages / second, without a global cap.
This commit introduces a simple sliding window rate limit feature
that counts the number of messages sent in a specific window, and
upon reaching that limit, waits for the window to reset before
any more messages are pushed out globally across any number of
campaigns.
Context: https://github.com/knadh/listmonk/issues/119
Lists, campaigns, and subscribers tables now support server-side
sorting from the UI. This significantly changes the internal
queries from prepared to string interpolated to support dynamic
sort params.
A new toggle switch in Settings -> Privacy, which is off by
default, allows campaign views (pixel) and link clicks to function
without registering the subscriber ID against view and click
events, anonymising tracking. When off, the subscriber UUIDs in
view and link tracking URLs are removed, anonymising subscriber
information from HTTP logs as well.
This is a major feature that builds upon the `Messenger` interface
that has been in listmonk since its inception (with SMTP as the only
messenger). This commit introduces a new Messenger implementation, an
HTTP "postback", that can post campaign messages as a standard JSON
payload to arbitrary HTTP servers. These servers can in turn push them
to FCM, SMS, or any or any such upstream, enabling listmonk to be a
generic campaign messenger for any type of communication, not just
e-mails.
Postback HTTP endpoints can be defined in settings and they can be
selected on campaigns.
Example given for CSV import on Import.vue is incorrect since
field `attributes` value is not a valid JSON. Previous example
copy pasted was throwing CSV parse error.
Vue's inbuilt dev server can be configured to proxy API for
development instead of directing developers to setup Nginx proxy.
Additionally this commit also adds an option to configure frontend port
on which dev server runs. Sample env config file is under
`frontend/.env.sample`, it can be copied to either `frontend/.env` or `frontend/.env.local`.
Available options are
LISTMONK_FRONTEND_PORT - Configure frontend dev server port (defaults to 8080)
LISTMONK_API_URL - Configure API server URL (defaults to http://127.0.0.1:9000)
Since env variables are sourced to current session we are prefixing it with `LISTMONK_`.
