The complexity of the situation is that we don't want to load faker into production by default but fabricators and styleguide are available on production.
This is made possible through app/assets/javascripts/discourse/app/lib/load-faker.js which contains a function to ensure faker is loaded asynchronously (loadFaker) and another function to access the loaded faker (getLoadedFaker).
Note 1: this commit also refactors fabricators to have access to context and use faker where possible
Note 2: this commit moves automation to admin bundle

Adds the new quick menu for bookmarking. When you bookmark
a post (chat message behaviour will come later) we show this new quick
menu and bookmark the item straight away.
You can then choose a reminder quick option, or choose Custom... to open
the old modal. If you click on an existing bookmark, we show the same quick menu
but with Edit and Delete options.
A later PR will introduce a new bookmark modal, but for now we
are using the old modal for Edit and Custom... options.
We need to scroll lock textareas when the keyboard is visible, otherwise they might become unusable if another element is body scroll locked on the page (eg: channels messages).
Note this commit is also slightly simplifying the code.
The expected behavior when receiving a message is the following:
- if user is at the bottom of the screen, scroll and append message
- if user is not at the bottom of the screen, don't scroll, show arrow and don't append message
This commit is making the following changes:
- replaces `mobile-keyboard` initializer and `chat-vh` with a new template-less component: `d-vh`
- ensures body scroll lock is released when page/tab focus changes
- correctly locks body on chat channels and chat threads when composer is focused
- removes `bodyScrollFix` as we now use body scroll lock
- `onViewportResize` has been debounced to ensure it's not a bad performance vector
- adds a reverse option do body scroll lock, this is made to support reversed scroll areas (like chat channels and threads)

- Converts all header buttons to use `<DButton`
- Updates `<DButton` to render `<a href=` tags when `@href` is passed (previously it was rendering a `<button`, and then using JS to route when clicked)
This commit fixes an issue where the following happens:
1. You open /admin as a member of the admin_sidebar_enabled_groups
1. You then click the chat icon in the header when you prefer to have
drawer open, or if you just minimise chat into drawer after it opens
fullscreen
1. You lose the admin sidebar panel, and are reset instead to the main
panel
Also included is a bit of refactoring to make it so the forcing of
admin sidebar state is in one place.
Prior to this change we would pre-load all the user channels which making initial page load slower. This change will make them be loaded right after initial load. In the past this was not possible as the channels would have to be loaded on each page transition. However since about a year, we made the channels to be cached on the frontend and no other request will be needed.
I have decided for now to not show a loading state in the sidebar as I think it would be noise, but we can reconsider this later.
Note given we don't have the channels loaded at first certain things where harder to accomplish. The biggest UX change of this commit is that we removed all the complex logic of computing the best channel to display when you load /chat. We will now store the id of the last channel you visited and will use this id to decide which channel to show.
On mobile, when viewing the My Threads area, each thread will show:
- The avatar of the last responder in the thread, overlaid with the chat thread symbol to visually distinguish this area from DMs.
- Either the thread title, where applicable, or the first message of the thread, truncated to fit on one line.
- The channel where the thread originated.
- The last message sent in the thread, truncated to fit on one line.
- When the last message was sent in the thread.

- The thread preview is now a regular link and can be right clicked
- left gutter date, and regular date of a thread message will not correctly link to the thread's message
Forcing a thread will work even in channel which don't have `threading_enabled` or in direct message channels.
For now this feature is only available through the `ChatSDK`:
```ruby
ChatSDK::Message.create(in_reply_to_id: 1, guardian: guardian, raw: "foo bar baz", channel_id: 2, force_thread: true)
```
Prior to this fix if a user had started to reply to a message without actually sending a message, the thread would still be created and we would end up listing it in the threads list of a channel.
This commit also improves adds thread and thread_replies_count to the 4th parameter of the chat_message_created event.
* UX: chat message creator scss cleanup + design tweak to username display
* add user status with live updates to modal
* show user status description in modal
* add tests for user status
* UX: add user-status styling to chat message creator

Prior to this fix clicking <kbd>x</kdb> on a channel row would effectively leave the channel on server side, but it wouldn't disappear from the screen before a page refresh.
With the adjustments of `btn-transparent` in https://github.com/discourse/discourse/pull/24666, there are more buttons that could use this class instead of `btn-flat`. This mostly relates to `x` close buttons, but also includes composer and chat toggles.
The primary difference between these styles is that `btn-transparent` never has a background, where `btn-flat` may have a hover or focus background.
`chat_preferred_mobile_index` allows to set the preferred default tab when loading chat on mobile.
Current choices are:
- channels
- direct_messages
- my_threads
```ruby
ChatSDK::Message.start_stream(message_id: 1, guardian: guardian)
ChatSDK::Message.stream(raw: "foo", message_id: 1, guardian: guardian)
ChatSDK::Message.stream(raw: "bar", message_id: 1, guardian: guardian)
ChatSDK::Message.stop_stream(message_id: 1, guardian: guardian)
```
Generally speaking only admins or owners of the message can interact with a message. Also note, Streaming to an existing message with a different user won't change the initial user of the message.
Prior to this fix the scroll was ignored when clicking the arrow bottom which would prevent the call to update last read. This fix manually calls update last read in this case and adds a test for it.
We have separated and combined modes for sidebar panels.
Separated means the panels show only their own sections,
combined means sections from all panels are shown.
The admin sidebar only shows its own panels, so it must set
the mode to separated; however when we navigate to chat or
home we must revert to the initial mode setttings.
This feature adds the functionality to start a new chat directly from the URL using query params.
The format is: /chat/new-message?recipients=buford,jona
The initial version of this feature allows for the following:
- Open an existing direct message channel with a single user
- Create a new direct message channel with a single user (and auto redirect)
- Create or open a channel with multiple users (and auto redirect)
- Redirects to chat home if the recipients param is missing
This commit introduces the possibility to stream messages. To allow plugins to use streaming this commit also ships a `ChatSDK` library to allow to interact with few parts of discourse chat.
```ruby
ChatSDK::Message.create_with_stream(raw: "test") do |helper|
5.times do |i|
is_streaming = helper.stream(raw: "more #{i}")
next if !is_streaming
sleep 2
end
end
```
This commit also introduces all the frontend parts:
- messages can now be marked as streaming
- when streaming their content will be updated when a new content is appended
- a special UI will be showing (a blinking indicator)
- a cancel button allows the user to stop the streaming, when cancelled `helper.stream(...)` will return `false`, and the plugin can decide exit early
Affects the following settings:
delete_all_posts_and_topics_allowed_groups
experimental_new_new_view_groups
enable_experimental_admin_ui_groups
custom_summarization_allowed_groups
pm_tags_allowed_for_groups
chat_allowed_groups
direct_message_enabled_groups
chat_message_flag_allowed_groups
This turns off client: true for these group-based settings,
because there is no guarantee that the current user gets all
their group memberships serialized to the client. Better to check
server-side first.
This commit was created with a combination of the ember-native-class-codemod and manual cleanup.
User-status-related functionality was previously encapsulated in its own `User.reopen` call, which is essentially an 'inline mixin'. This commit refactors it into a utility class, with an instance accessible on `User#statusManager`
The service `Chat::CreateMessage` will now accept `context_post_ids` and `context_topic_id` as params. These values represent the topic which might be visible when sending a message (for now, this is only possible when using the drawer).
The `DiscourseEvent` `chat_message_created` will now have the following signature:
```ruby
on(:chat_message_created) do | message, channel, user, meta|
p meta[:context][:post_ids]
end
```
Channels can include emojis in front of the channel title which causes problems when sorting.
Using the channel slug is a more reliable way to sort and avoid these kind of issues.
This change will sort channels by activity on mobile, with preference to those with urgent or unread messages.
Channels with mentions will appear first, followed by channels with unread messages, then finally everything else sorted by the channel title (alphabetically).
This commit includes several changes to make hashtags work when "lazy
load categories" is enabled. The previous hashtag implementation use the
category colors CSS variables, but these are not defined when the site
setting is enabled because categories are no longer preloaded.
This commit implements two fundamental changes:
1. load colors together with the other hashtag information
2. load cooked hashtag data asynchronously
The first change is implemented by adding "colors" to the HashtagItem
model. It is a list because two colors are returned for subcategories:
the color of the parent category and subcategory.
The second change is implemented on the server-side in a new route
/hashtags/by-ids and on the client side by loading previously unseen
hashtags, generating the CSS on the fly and injecting it into the page.
There have been minimal changes outside of these two fundamental ones,
but a refactoring will be coming soon to reuse as much of the code
and maybe favor use of `style` rather than injecting CSS into the page,
which can lead to page rerenders and indefinite grow of the styles.
The leave channel button is cut off when accessing the channel settings page on mobile.
This change adds additional padding to the bottom of the channel settings page when accessing via iPad/PWA/Hub.
Chat mobile has separate routes for channels and direct messages. However on desktop we want to prevent these routes from being accessible as they aren't intended to be used by chat in full-page or drawer mode on desktop.
We had two issues which were present for a long time I think:
- one that impacts both core discourse and chat. We were not setting top on the header when `footer-nav-ipad` was present, meaning that you could make it scroll under if you try to scroll up by putting your finger on the discourse header
- one that impacted only chat. It's also present in core, but in core it's not a probem because we don't have a fixed height div. The body height was higher than the screen which would cause a second scrollbar to appear and would slightly break layout, if you scroll on this scrollbar (body).
* UX: increase font-size of last message + decrease emoji size
* UX: decrease size of username emoji
* UX: Mobile chat index cleanup
* UX: decrease size of chat-channel-title in thead list
Chat should follow the same convention as topics, where invalid mentions
are not styled the same as valid mentions. This PR makes chat use such styling.
I'm following the same pattern that we use for invalid mentions in posts –
9bd6523581/app/assets/stylesheets/common/base/topic-post.scss (L1285-L1288)
This way it'll be easier to dry it up if we decide to do that at some point.
This commit adds a link to the original message of a thread, this link will:
- load the channel message and highlight it while keeping thread panel open on desktop
- open the channel and highlight the message in mobile (and close thread panel, as mobile never shows channel and thread in the same view)

Since https://github.com/discourse/discourse/pull/25501 this behavior was broken. This PR attempts to fix it by being more fine grain.
Also note that this PR is moving `footer-nav-ipad` and `footer-nav-visible` to the `html` element and not the `body`. It makes more sense as we are already adding most of other global state class like `keyboard-visible` to the `html` element.
Tested on:
- chrome desktop
- safari ios - iphone
- PWA ios - iphone
- PWA ios - ipad
- DiscourseHub iphone
This commit sets a default of 0px for `--footer-nav-height` and set it only when `body.footer-nav-visible` allowing us to safely use `--footer-nav-height` wherever it will be needed if set.
When reaching the top of a thread, the full thread title will be displayed if it was too long to fit.
It works in mobile, drawer mode, and fullscreen.

This change adds notification badges to the new footer tabs on mobile chat, to help users easily find areas where there’s new activity to review.
When on mobile chat:
- Show a badge on the DMs footer when there is unread activity in DMs.
- Show a badge on the Channels footer tab when there is unread channel activity.
- Show a badge on the Threads footer tab when there is unread activity in a followed thread.
- Notification badges should be removed once the unread activity is viewed.
Additionally this change will:
- Show green notification badges for channel mentions or DMs
- Show blue notification badges for unread messages in channels or threads

The value [Yesterday] was a fixed string which couldn't be translated. Also removes nextWeek/nextDay which make no sense for dates which are always supposed to be in the past.
Having the admin sidebar code in an instance initializer is not
ideal because:
* It runs during app boot which may not even be necessary based on site settings
* It makes it hard for plugins to register additional links in time without resorting
to before/after initializer gymnastics
This PR moves the admin sidebar into a lib and creates the panel
in custom-sections.js, then the sections and links are loaded when
the main sidebar component is rendered, which leaves plugins enough
time to add additional links in an initializer.

Fixes an issue with delayed rendering of the My Threads tab in chat mobile footer.
Previously we made an ajax request to determine the number of threads a user had before rendering the tab, however it is much faster (and better UX) if we can rely on a site setting for this.
The new chat_threads_enabled site setting is set to true when the site has chat channels with threading enabled.
This bug was causing broken layout when using the `header_dropdown` setting instead of `sidebar` as we were rendering `<div class="channels-list"></div>` two times.
In normal use, this `text()` getter is never called. However, when running with the Ember inspector, it is eagerly evaluated and hits throws the "not implemented" error in the base class.
* FIX: Minor bookmark issues
* We were showing "missing %{name} value" when the name for the
bookmark was undefined with title translations
* There was no way to see the bookmark details on hover in chat
for a message where the bookmark icon was in the left gutter.
We can show the title on the bookmark button in the chat message
actions instead.
* Minor fix
* DEV: Test fix
Due to an incorrect test the previous service was incorrectly implementing the map, and was most importantly not deleting the state when reaching bottom.
It was broken on iOS PWA, when you had the keyboard open and would leave the app. When you came back the body was scrolled and it was looking buggy until you close/reopen keyboard.
This commit attempt to reposition the page correctly 200ms after the tab is visible again.
This commit creates a shared implementation of the dates computation and moves all the logic (new messages since last visit and dates separator into one single component <ChatMessageSeparator />).
The frontend tests have been removed and only a single system spec has been added for threads as everything is sharing the same implementation and the existing channel specs should catch any regression.
Allows users to create DMs by selecting groups as a target. It also allows adding user groups to an existing chat
- When creating the channel, it expands the user group and adds all its members with chat enabled to the channel.
- After creation, there's no difference between adding a group or adding its members individually.
- Users can add multiple groups and users simultaneously.
- There are UI validations; the member count preview updates according to the member count of added groups, and it does not allow users to add more members than SiteSetting.chat_max_direct_message_users."
This change moves the "Channels" tab to first position in the chat footer nav, and loads it as the default page when opening chat for the first time on mobile.
This update adds three tabs to the bottom of the chat overlay to make it easier for users to navigate chat on mobile.
As a result of this change:
- Direct Messages are now shown separately from public channels on mobile
- My Threads has now moved from the channel list to it's own tab on mobile
- My Threads can still be accessed on desktop via the sidebar and within the drawer channel list
- Chat back button has been updated to navigate to the correct tab (for both channels and threads)
Some special cases:
- If DMs are not used then the tab is not rendered
- If the user has no threads then the tab is not rendered
- If both the tabs for DMs and Threads aren't available then the whole footer will not be rendered
- Chat footer is only shown on the listing pages (DMs, Channels, My Threads)

This commit:
- increased the size of chat-header-offset from 46px to 56px on mobile
- tweaked navbar padding
- Increased the gap between back button and title; this means no more perfect alignment, but I think that's perfectly fine and a fair trade off for an easier click target for the back button without fear of hitting the title
Small visual improvements for chat header on mobile:
- makes the Back to Forum target size slightly narrower
- makes the text color consistent between header and back button (and d-icon)
- makes the chat heading bold
This change simplifies the layout of our header when chat is open on mobile. The search icon and hamburger menu icons are also hidden and the Discourse logo is replaced by a ← Forum link to make it easier to continue where you left off within the forum (prior to this update the user could only go back to the forum index page).
## Back button to navigate out of add-member area
Currently on mobile, once you're in the member area, there is no easy to return to the general settings area, except exiting the settings altogether, which isn't very user friendly. A go-back link solves the problem.
## Styling tweaks
* Removed the background from the leave button
* Added more spacing between the sections on desktop and removed the fixed height for rows

This new navbar component is used for every navbar in chat, full page or drawer, and any screen.
This commit also uses this opportunity to correctly decouple drawer-routes from full page routes. This will avoid having this kind of properties in components: `@includeHeader={{false}}`. The header is now defined in the parent template using a navbar. Each route has now its own template wrapped in a div of the name of the route, eg: `<div class="c-routes-threads">..</div>`.
The navbar API:
```gjs
<Navbar as |navbar|>
<navbar.BackButton />
<navbar.Title @title="Foo" />
<navbar.ChannelTitle @channel={{@channel}} />
<navbar.Actions as |action|>
<action.CloseThreadButton />
</navbar.Actions>
</navbar>
```
The full list of components is listed in `plugins/chat/assets/javascripts/discourse/components/navbar/index.gjs` and `plugins/chat/assets/javascripts/discourse/components/navbar/actions.gjs`.
Visually the header is not changing much, only in drawer mode the background has been removed.
This commit also introduces a `<List />` component to facilitate rendering lists in chat plugin.
- sticky doesn't work well with overflow: hidden parents. These overflows were used to hide other issues which shouldn't exist anyways. If it causes issues we should fix the root cause.
- our `--header-offset` is changing a lot on safari while scrolling, sometimes with very unexpected value like: negative or very high value, which causes the navbar to appear at unexpected positions for few ms, this commit is using the value of the header on insert and not changing it after, it shouldn't cause any issue.
We can also now control tabindex, and other html attributes, which allows to lick on the thread indicator but not tab to it for example.
By default the tabindex will be 0.
When navigating to /chat/threads we were not closing the side panel. It would not show as the route doesn't support it, but after if we would open a channel from the sidebar it would open the channel with an empty opened sidepanel .
This commit adds a new "My threads" link in sidebar and drawer. This link will open the "/chat/threads" page which contains all threads where the current user is a member. It's ordered by activity (unread and then last message created).
Moreover, the threads list of a channel page is now showing every threads of a channel, and not just the ones where you are a member.
Introduces the concept of image thumbnails in chat, prior to this we uploaded and used full size chat images within channels and direct messages.
The following changes are covered:
- Post processing of image uploads to create the thumbnail within Chat::MessageProcessor
- Extract responsive image ratios into CookedProcessorMixin (used for creating upload variations)
- Add thumbnail to upload serializer from plugin.rb
- Convert chat upload template to glimmer component using .gjs format
- Use thumbnail image within chat upload component (stores full size img in orig-src data attribute)
- Old uploads which don't have thumbnails will fallback to full size images in channels/DMs
- Update Magnific lightbox to use full size image when clicked
- Update Glimmer lightbox to use full size image (enables zooming for chat images)
This outlet allows to redefine the button displayed when asking the user to join a channel.
The following outletArgs are sent to the outlet:
```
onJoinChannel
channel
icon
title
label
disabled
```
Prior to this fix direct message would always show "Chat in ..." when hovering the channel even if you were hovering a direct message channel with another user (or yourself).
We will now correctly show:
- `Chat in ...` for group channels
- `Chat with ...` for direct message channels
In other kind of channels we will only unfollow but for group channels we don't want people to keep appearing in members list.
This commit also creates appropriate services:
- `Chat::LeaveChannel`
- `Chat::UnfollowChannel`
And dedicated endpoint for unfollow: `DELETE /chat/api/channels/:id/memberships/me/follows`
This PR introduces thread support for channel archives. Now, threaded messages are rendered inside a `details` HTML tag in posts.
The transcript markdown rules now support two new attributes: `threadId` and `threadTitle`.
- If `threadId` is present, all nested `chat` tags are rendered inside the first one.
- `threadTitle` (optional) defines the summary content.
```
[chat threadId=19 ... ]
thread OM
[chat ... ]
thread reply
[/chat]
[/chat]
```
If threads are split across multiple posts when archiving, the range of messages in each part will be displayed alongside the thread title. For example: `(message 1 to 16 of 20)` and `(message 17 to 20 of 20)`.
Before this fix we would reset the input two times:
- right before sending message
- and after it's been sent
The second one is actually not necessary, and more over with the server delay the user could have started typing a new message and that would clear it.
Mentions and other post processing (like images) are still done asynchronously in the background. This should ensure reloading a channel while the message has not been processed yet doesn’t renders a blank message.
As a followup, we could probably simplify the staged message logic, given we have the new cooked on send.
This commit implements drafts for threads by adding a new `thread_id` column to `chat_drafts` table. This column is used to create draft keys on the frontend which are a compound key of the channel and the thread. If the draft is only for the channel, the key will be `c-${channelId}`, if for a thread: `c-${channelId}:t-${threadId}`.
This commit also moves the draft holder from the service to the channel or thread model. The current draft can now always be accessed by doing: `channel.draft` or `thread.draft`.
Other notable changes of this commit:
- moves ChatChannel to gjs
- moves ChatThread to gjs
Fixes a minor issue where "Invalid date" is shown briefly
when sending a message in a chat thread. Change to use
`new Date()` instead like the channel staged message which
does not have this issue.
This PR refactors the following:
* leaving all the CSS applied to the old `modal-body` classes in their respective files
* made new clean styling for `.d-modal` and refactored the template to use the new BEM classes
* `inner-`, `middle-`, `outer-` container classes are gone and replaced with simplified `wrapper` and `container` classes
* use standardised max-sizes with modifiers `-large` and `-max`
* lighter backdrop,
* min-width to prevent puny modals
* other styling changes regarding padding, close button,…
* pulled out all modal overrides into a general `modal-overrides` file + cleanup of outdated CSS
* pulled out login and create account modal styling into their own file, cause it's such a big override
* removed old general login.scss file for mobile & desktop
* only kept some remainders I don't want to touch in `app/assets/stylesheets/common/base/login.scss`
Some of these files are quite small, and if we rename them in the same
commit where we inlined the template, Git may choose to see them as
different files. This commit forces Git to recognize the rename, which
will preserve the lineage of the refactored files.
Follow-up to #24278 that is slightly less trivial.
* Some were "trivial" usages that were missed in the previous PR because the same file that had at least one other non-trivial usage.
* These involve extra arguments or inheritance but I have checked that they seem correct.
Group channels will allow users to create channels with a name and invite people. It's possible to add people even after creation of the channel. Removing users is not yet possible but will be added in the near future.
Technically a group channel is `direct_message_channel` with a group attribute set to true on its direct message (chatable). This model might evolve in the future but offers much flexibility for now without having to rely on a complex migration.
The commit essentially consists of:
- a migration to set existing direct message channels with more than 2 users to a group
- a new message creator which allows to search, add members, and create groups
- a new `AddUsersToChannel` service
- a modified `SearchChatable` service
Subscriptions manager have been a pain since the beginning, one of the problem is that thread and channels behave mostly the same but with various small difference which I expect to increase over time.
Trying to use subclasses for this case has proven to be a mistake, this commit now uses a class for each case (channel, thread) which for now contains a lot of duplication, which might be reduced in the future but has the merit to make reasoning about each case very simple.
This refactor is fixing a bug introduced in 90efdd7f9d which was causing the wrong channel to be unsubscribed, this shouldn't be possible anymore. We had tests for this which were disabled due to flakeyness, I will consider re-enabling them in the future.
Other notes:
- notices had been added to the subscriptions manager service, they have been moved into their own dedicated service: `ChatChannelNoticesManager`
- the `(each model)` trick used in `<ChatChannel />` since 90efdd7f9d to ensure atomicity has been applied to `<ChatThread />` too
Chat redesign work to improve chat navigation:
- New header title with channel name (thread list on mobile)
- New header title without channel name (thread list on full page chat)
- Removes the close button on threads (mobile only)
- Updates to back button route within thread (mobile), taking user to:
- The thread index, if they accessed the thread from the thread index.
- The channel itself, if they accessed the thread directly from the channel.
- The channel itself, if they accessed the thread from a notification.
- Show thread title in chat drawer header
- Properly convert emoji in thread titles in chat header (all devices)
- Upgrades various templates to use gjs format.
This commit starts from a simple observation: cooking messages on the hot path can be slow. Especially with a lot of mentions.
To move cooking from the hot path, this commit has made the following changes:
- updating cooked, inserting mentions and notifying user of new mentions has been moved inside the `process_message` job. It happens right after the `Chat::MessageProcessor` run, which is where the cooking happens.
- the similar existing code in `rebake!` has also been moved to rely on the `process_message`job only
- refactored `create_mentions` and `update_mentions` into one single `upsert_mentions` which can be called invariably
- allows services to decide if their job is ran inline or later. It avoids to need to know you have to use `Jobs.run_immediately!` in this case, in tests it will be inline per default
- made various frontend changes to make the chat-channel component lifecycle clearer. we had to handle `did-update @channel` which was super awkward and creating bugs with listeners which the changes of the PR made clear in failing specs
- adds a new `-processed` (and `-not-processed`) class on the chat message, this is made to have a good lifecyle hook in system specs
When uploading images, they are assigned a dominant color which gets used in various places, such as Discourse Hub and the new lightbox. Previously in chat we didn't assign this attribute, so it was defaulting to a null value. We did however use it as an inline CSS style for the image background (which is visible while the image is downloaded).
This change adds data-dominant-color to the uploaded image in chat and uses it correctly within lightbox.
Add new chat indicator preference within chat user preferences.
Enabling this option will mean that green notifications will only appear for mentions (within channels and DMs.
This change also enables mentions within direct messages.
