This commit adds a new API `POST /api/tx` that sends an ad-hoc message
to a subscriber based on a pre-defined transactional template. This is
a large commit that adds the following:
- New campaign / tx template types on the UI. tx templates have an
additional subject field.
- New fields `type` and `subject` to the templates table.
- Refactor template CRUD operations and models.
- Refactor template func assignment in manager.
- Add pre-compiled template caching to manager runtime.
- Pre-compile all tx templates into memory on program boot to avoid
expensive template compilation on ad-hoc tx messages.
This is a long pending refactor. All the DB, query, CRUD, and related
logic scattered across HTTP handlers are now moved into a central
`core` package with clean, abstracted methods, decoupling HTTP
handlers from executing direct DB queries and other business logic.
eg: `core.CreateList()`, `core.GetLists()` etc.
- Remove obsolete subscriber methods.
- Move optin hook queries to core.
- Move campaign methods to `core`.
- Move all campaign methods to `core`.
- Move public page functions to `core`.
- Move all template functions to `core`.
- Move media and settings function to `core`.
- Move handler middleware functions to `core`.
- Move all bounce functions to `core`.
- Move all dashboard functions to `core`.
- Fix GetLists() not honouring type
- Fix unwrapped JSON responses.
- Clean up obsolete pre-core util function.
- Replace SQL array null check with cardinality check.
- Fix missing validations in `core` queries.
- Remove superfluous deps on internal `subimporter`.
- Add dashboard functions to `core`.
- Fix broken domain ban check.
- Fix broken subscriber check middleware.
- Remove redundant error handling.
- Remove obsolete functions.
- Remove obsolete structs.
- Remove obsolete queries and DB functions.
- Document the `core` package.

contains changes and refactors that could not be pushed to the original PR.
Changes from #707
- Don't ignore bounce mails missing campaign / subscriber UUIDs. The
original behaviour falls back to looking up subscribers by e-mail.
- Refactor repetetive header.get + regexp conditions per header into
a simpler lookup map.
- Trim e-mail header values of `\r`.
Closes#707, #763
Co-authored-by: stevesavanna <steven@savannacorp.com>
- Change `query-lists` query to aggregate the subscriber count by
status (confirmed, unsubscribed etc.) and expose them under a new
`subscriber_statuses: {}` field in the `GET /lists` API.
- Display the statuses and counts in the lists table on the UI.
Closes#616
- Add new `headers[]` column to the campain table.
- Add new headers box to the campaign UI that takes a JSON array of
custom headers like the headers on the SMTP settings UI.
- Headers are added to e-mails and messenger postback webhooks.
- Add cypress tests.
Closes#514.
- echo is now on v4 with major changes including a few breaking changes
- bind() behaviour is now strict. JSON / form etc. unmarshalling of
request data need appropriate `json`, `form` tags. Missing tags for
the public subscription page is added in this commit.
- This also closes#602.
The default `{{ TrackLink "https://listmonk.app" }}` template function
is clumsy to write and does breaks WYSIWYG editors and HTML syntax
highlighting because of the quotes. The new syntax doesn't break HTML
and is easier to write.
Eg: `<a href="https://listmonk.app@TrackLink">Link</a>`
- Introduce @TrackLink shorthand.
- Add first-class support for tracking links in the WYSIWYG (TinyMCE)
editor by introducing an on/off checkbox on the link dialog.
- Improve default dummy campaign content to highlight this.
- Add indexes.
- Refactor dashboard charts and view/click count queries.
(~10x speed bump on a setup of 7mn subscribers and 80mn views)
- Refactor get subscriber queries.
(~10x speed bump on 7mn subscribers)
- Make subscriber UI issue an equality query for email seach strings.
- Blocklist or unsubscribe subscribers based on a bounce threshold
- Add /bounces UI for viewing bounces and in the subscriber view
- Add settings UI for managing bounce settings
- Add support for scanning POP3 bounce mailboxes
- Add a generic webhook for posting custom bounces at /webhooks/bounce
- Add SES bounce webhook support at /webhooks/services/ses
- Add Sendgrid bounce webhook support at /webhooks/services/sendgrid
Previously, converting between formats simply copied over raw content.
This update does actual conversion between different formats. While
lossy, this seems to a good enough approximation for even reasonbly
rich HTML content. Closes#348.
- richtext, html => plain
Strips HTML and converts content to plain text.
- richtext, html => markdown
Uses turndown (JS) lib to convert HTML to Markdown.
- plain => richtext, html
Converts line breaks in plain text to HTML breaks.
- richtext => html
"Beautifies" the HTML generated by the WYSIWYG editor unlike the
earlier behaviour of dumping one long line of HTML.
- markdown => richtext, html
Makes an API call to the backend to use the Goldmark lib to convert
Markdown to HTML.
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.
- 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.
- Campaigns now have a `type` property (regular, opt-in)
- Opt-in campaigns work for double opt-in lists and e-mail
subscribers who haven't confirmed their subscriptions.
- Lists UI shows a 'Send opt-in campaign' optin that
automatically creates an opt-in campaign for the list
with a default message body that can be tweaked before
sending the campaign.
- Primary usecase is to send opt-in campaigns to subscribers
who are added via bulk import.
This is a breaking change. Adds a new Postgres enum type
`campaign_type` and a new column `type` to the campaigns table.
- Lists can now be marked as single | double optin.
- Insert subscribers to double opt-in lists send out a
confirmation e-mail to the subscriber with a confirmation link.
- Add `{{ OptinURL }}` to template functions.
This is a breaking change. Adds a new field 'optin' to the lists
table and changes how campaigns behave. Campaigns on double opt-in
lists exclude subscribers who haven't explicitly confirmed subscriptions.
Changes the structure and behaviour of how notification e-mail routines,
including notif email template compilation, notification callbacks for
campaign and bulk import completions.
- Better template function shorthand substitution.
- Make `UnsubscribeURL` a function consitent with TrackLink.
This is a breaking change that makes the old `.UnsubscrbeURL`
obsolete.
This commit introduces a `blobstore` package and refactors the existing
upload mechanism. Upload is now handled by `providers` and the two
bundled providers are `S3` and `Filesystem`. `app.Blobstore` initialises
the correct provider based on the configuration and handles `Put`,
`Delete` and `Get` operations.
- Simplify campaigns querying to separate statistics gather into
a separate query for lazy loading.
- Simplify subscribers query to separate list fetching into
a separate query for lazy loading.
Quill link dialog (righly) escapes quotes in URL values there by breaking the
TrackLink() template function. That is, {{ TrackLink "https://listmonk.app" }}
when inserted using the Quill link dialog would become
{{ TrackLink "https://listmonk.app" }}. A simplework around is to
add support to backticks so that the template parser works with
{{ TrackLink `https://listmonk.app` }}
