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.
- 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.
- Refactor codeflask HTML editor into a standalone html-editor
component.
- Replace the plaintext box in the template editor with html-editor.
- Replace codeflask in the campaign editor with the new html-editor.
- Refactor templates Cypress tests to test the new editor.
- Refactor campaigns Cypress tests to test the new editor and also
test switching between different editors and content formats.
Campaign messages are handled by `manager` whereas test messages
were being pushed directly into a messenger skipping some campaign
related routines such as the addition of list unsub headers.
This commit exposes a new function `manager.PushCampaignMessage()`
that accepts arbitrary campaign messages that then pass through
the standard campaign message workers, thus getting the missing unsub
headers. This closes#360.
In addition, this removes the superfluous `CampaignMessage.Render()`
function which had to be mandatorily called always and makes it
implicit in `manager.NewCampaignMessage()`.
