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.
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.
- Change global font to Inter.
- Introduce global top nav bar.
- Restyle form inputs to have inline labels.
- Restyle form inputs to have inline lengt counters.
- Override glitchy Buefy animations (sidebar, toast etc.)
- Fix tag alignment inside tables in responsive view.
- Refactor import page UI.
- Miscellaneous styling fixes.
- Add missing Fontello icons.
Instead of using a response transformer, move the global response
JSON transformation (snake case to camel case) to the pre-existing
response interceptor. Also, fix the `data.data` and `data`
discrepancy in responses.
- antd+react was resulting in extremely clunky and unreadable
spaghetti frontend code (primarily due to how antd is).
- Buefy is lighter by an order of magnitude, has excellent
responsive views (especially tables) and usability.
- Vue's templating produces far more readable template code.
