This commit adds the thread index and individual thread
in the index list unread indicators, and wires up the message
bus events to mark the threads as read/unread when:
1. People send a new message in the thread
2. The user marks a thread as read
There are several hacky parts and TODOs to cover before
this is more functional:
1. We need to flesh out the thread scrolling and message
visibility behaviour. Currently if you scroll to the end
of the thread it will just mark the whole thread read
unconditionally.
2. We need to send down the thread current user membership
along with the last read message ID to the client and
update that with read state.
3. We need to handle the sidebar unread dot for when threads
are unread in the channel and clear it based on when the
channel was last viewed.
4. We need to show some indicator of thread unreads on the
thread indicators on original messages.
5. UI improvements to make the experience nicer and more
like the actual design rather than just placeholders.
But, the basic premise around incrementing/decrementing the
thread overview count and showing which thread is unread
in the list is working as intended.
This commit adds an initial thread list UI. There are several limitations
with this that will be addressed in future PRs:
* There is no MessageBus reactivity, so e.g. if someone edits the original
message of the thread it will not be reflected in the list. However if
the thread title is updated the original message indicator will be updated.
* There is no unread functionality for threads in the list, if new messages
come into the thread there is no indicator in the UI.
* There is no unread indicator on the actual button to open the thread list.
* No pagination.
In saying that, this is the functionality so far:
* We show a list of the 50 threads that the user has most recently participated
in (i.e. sent a message) for the channel in descending order.
* Each thread we show a rich excerpt, the title, and the user who is the OM creator.
* The title is editable by staff and by the OM creator.
* Thread indicators show a title. We also replace emojis in the titles.
* Thread list works in the drawer/mobile.
This commit implements all the necessary logic to create thread seamlessly. For this it relies on the same logic used for messages and generates a `staged-id`(using the format: `staged-thread-CHANNEL_ID-MESSAGE_ID` which is used to re-conciliate state client sides once the thread has been persisted on the backend.
Part of this change the client side is now always using real thread and channel objects instead of sometimes relying on a flat `threadId` or `channelId`.
This PR also brings three UX changes:
- thread starts from top
- number of buttons on message actions is dependent of the width of the enclosing container
- <kbd>shift + ArrowUp</kbd> will reply to the last message
This pull request is a full overhaul of the chat-composer and contains various improvements to the thread panel. They have been grouped in the same PR as lots of improvements/fixes to the thread panel needed an improved composer. This is meant as a first step.
### New features included in this PR
- A resizable side panel
- A clear dropzone area for uploads
- A simplified design for image uploads, this is only a first step towards more redesign of this area in the future
### Notable fixes in this PR
- Correct placeholder in thread panel
- Allows to edit the last message of a thread with arrow up
- Correctly focus composer when replying to a message
- The reply indicator is added instantly in the channel when starting a thread
- Prevents a large variety of bug where the composer could bug and prevent sending message or would clear your input while it has content
### Technical notes
To achieve this PR, three important changes have been made:
- `<ChatComposer>` has been fully rewritten and is now a glimmer component
- The chat composer now takes a `ChatMessage` as input which can directly be used in other operations, it simplifies a lot of logic as we are always working a with a `ChatMessage`
- `TextareaInteractor` has been created to wrap the existing `TextareaTextManipulation` mixin, it will make future migrations easier and allow us to have a less polluted `<ChatComposer>`
Note ".chat-live-pane" has been renamed ".chat-channel"
Design for upload dropzone is from @chapoi
- Back button in drawer will bring you back to channel
- Larger font for thread indicator
- Prevents screen flashing due to clearing messages when they were already loaded
- Fixes a bug where did-update params were inverted causing an error when expanding/collapsing drawer
This commit is a major overhaul of how chat message actions work, to make it so they are reusable between the main chat channel and the chat thread panel, as well as many improvements and fixes for the thread panel.
There are now several new classes and concepts:
* ChatMessageInteractor - This is initialized from the ChatMessage, ChatMessageActionsDesktop, and ChatMessageActionsMobile components. This handles permissions about what actions can be done for each
message based on the context (thread or channel), handles the actions themselves (e.g. copyLink, delete, edit),
and interacts with the pane of the current context to modify the UI
* ChatChannelThreadPane and ChatChannelPane services - This represents the UI context which contains the
messages, and are mostly used for state management for things like message selection.
* ChatChannelThreadComposer and ChatChannelComposer - This handles interaction between the pane, the
message actions, and the composer, dealing with reply and edit message state.
* Scrolling logic for the messages has now been moved to a helper so it can be shared between the main channel pane and the thread pane
* Various improvements with the emoji picker on both mobile and desktop. The DOM node of each component is now located outside of the message which prevents a large range of issues.
The thread panel now also works in the chat drawer, and the thread messages have less
actions than the main panel, since some do not make sense there (e.g. moving messages to
a different channel). The thread panel title, excerpt, and message sender have also been removed
for now to save space.
This gives us a solid base to keep expanding on and fixing up threads. Subsequent PRs will
make the thread MessageBus subscriptions work and disable echo mode
for the initial release of threads.

Note this is a very large PR, and some of it could have been splited, but keeping it one chunk made it to merge conflicts and to revert if necessary. Actual new code logic is also not that much, as most of the changes are removing js tests, adding system specs or moving things around.
To make it possible this commit is doing the following changes:
- converting (and adding new) existing js acceptances tests into system tests. This change was necessary to ensure as little regressions as possible while changing paradigm
- moving away from store. Using glimmer and tracked properties requires to have class objects everywhere and as a result works well with models. However store/adapters are suffering from many bugs and limitations. As a workaround the `chat-api` and `chat-channels-manager` are an answer to this problem by encapsulating backend calls and frontend storage logic; while still using js models.
- dropping `appEvents` as much as possible. Using tracked properties and a better local storage of channel models, allows to be much more reactive and doesn’t require arbitrary manual updates everywhere in the app.
- while working on replacing store, the existing work of a chat api (backend) has been continued to support more cases.
- removing code from the `chat` service to separate concerns, `chat-subscriptions-manager` and `chat-channels-manager`, being the largest examples of where the code has been rewritten/moved.
Future wok:
- improve behavior when closing/deleting a channel, it's already slightly buggy on live, it's rare enough that it's not a big issue, but should be improved
- improve page objects used in chat
- move more endpoints to the API
- finish temporarily skipped tests
- extract more code from the `chat` service
- use glimmer for `chat-messages`
- separate concerns in `chat-live-pane`
- eventually add js tests for `chat-api`, `chat-channels-manager` and `chat-subscriptions-manager`, they are indirectly heavy tested through system tests but it would be nice to at least test the public API
<!-- NOTE: All pull requests should have tests (rspec in Ruby, qunit in JavaScript). If your code does not include test coverage, please include an explanation of why it was omitted. -->
- better handling of drawer state using chat state manager
- removes various float and topic occurrences to use drawer
- ensures user can chat before doing a lot of chat setup
- fixes a bug which was creating presence errors in tests
- removes dead code
- Note this is also tweaking the UI a little bit as we are now using links/buttons in the header as needed
- It disables the find ideal channel in drawer mode, if loading `/chat` in drawer mode it will either reopen at the last position or just stay on index
