rCOMM3fd1233147c1: [web] Change ThreadList behaviour after hiding ChatThreadComposer

Summary

Depends on D4939
Context: here

Changing behaviour after closing ChatThreadComposer.

Now, when we close thread composer on pending thread by clicking the X button, app will focus on the first thread on the top of the list

In other cases, app will focus on the currently generated or matched thread.

Also, this diff improves behavior of ChatThreadListItem onClick event. Now, clicking on currently active thread in chat creation mode doesn't close ChatThreadComposer.

Test Plan

Steps to test new ChatThreadComposer behavior:

Click Create new chat
Create pending thread (don't select any users or select set of users, which doesn't match to any existing thread)
Close composer by click X button

Now, app is currently focused on the first thread from the thread list.

In other cases, when we send a message to a new thread or we close ChatThreadComposer on an already existing thread, app keeps focus on the current thread.

Steps to test new ChatThreadListItem behavior:

Click Create new chat: a) Click on currently active ChatThreadListItem -> chat creation mode still active b) Click on any other ChatThreadListItem -> app switches active chat item to the new one and closes chat creation mode

web/chat/chat-thread-composer.react.js
26 ↗	(On Diff #15962)	Let's make this more specific. It should be clear at the callsite what the parameter does. Right now, it's not clear at the callsite what is being "kept" or "cleared"

• jakub added inline comments.Aug 28 2022, 9:26 PM

web/chat/chat-thread-composer.react.js
26 ↗	(On Diff #15962)	Could it be "keep-thread-id" and "clear-thread-id"/"change-thread-id"?

web/chat/chat-thread-composer.react.js
169–171		We should memoize the callback
26 ↗	(On Diff #15962)	Instead of focusing on the implementation detail that we use thread id, the name should focus on the difference in behavior. So it this case it should tell whether we're going to stay on the page or open something else.

This revision now requires changes to proceed.Aug 30 2022, 9:13 AM

• jakub added inline comments.Aug 31 2022, 2:53 AM

web/chat/chat-thread-composer.react.js
169–171	Sure

Memoize onClick callback and change enum value names

Harbormaster completed remote builds in B11733: Diff 16123.Aug 31 2022, 3:12 AM

I tested it a bit and discovered a couple of strange behaviors:

When we have a pending thread opened and we click it on threads list it gets closed - should we really do that?
When we have a pending thread opened with some users selected, clicking it doesn't result in it being closed - it remains displayed on the list and its message view is still presented but not in the search mode.

web/selectors/nav-selectors.js
145–170 ↗	(On Diff #16123)	We have duplicated logic here. Can we refactor it so that there's just one `dispatch`?

This revision now requires changes to proceed.Aug 31 2022, 5:14 AM

Change thread behaviour and refactor logic in nav-selectors.js

I changed both behaviours. Now, after clicking on active thread in create mode, app keeps focused on it and ThreadComposer doesn't close.
I also considered using a css class with pointer-event: none property instead to dynamically disable onClick event, but this solution has an impact on children pointer-events, so it could be problematic (e.g. onClick on ChatThreadListItemMenu)

web/selectors/nav-selectors.js
145–170 ↗	(On Diff #16123)	Sure

Harbormaster completed remote builds in B11803: Diff 16206.Sep 1 2022, 7:48 AM

I tested it and wasn't able to break it, so it works correctly. Added one question because I would like to understand it better why it works correctly.

web/chat/chat-thread-composer.react.js
121 ↗	(On Diff #16206)	Could you explain why setting empty string here works correctly?

This revision now requires changes to proceed.Sep 2 2022, 6:57 AM

• jakub added inline comments.Sep 8 2022, 4:18 AM

web/chat/chat-thread-composer.react.js
121 ↗	(On Diff #16206)	When we update redux state, every time new state is validated by `validateState` function. If we pass empty string or invalid threadID, this function will catch it and guarantee returning a most recent readed thread id. Here is part of code responsible for this.

Rebase

Harbormaster completed remote builds in B12016: Diff 16498.Sep 8 2022, 6:45 AM

Really nice! Just a couple minor comments inline.

web/chat/chat-thread-composer.react.js
121 ↗	(On Diff #16206)	Ok, that makes a lot of sense. We could consider determining this thread here, but it's better to let reducer figure it out. It would be a lot safer to use `null` instead of empty string, though.
web/chat/chat-thread-list-item.react.js
140 ↗	(On Diff #16498)	Can we create a callback that calls `onClick` conditionally and could be used here? From performance point of view it shouldn't matter, but it would be more readable to have this logic in a callback instead of setting the prop conditionally here.
web/selectors/nav-selectors.js
131 ↗	(On Diff #16498)	In the most recent solution we use `newThreadID` only in `chat-message-list-container` so maybe we should revert moving it and keep it in `chat-message-list-container`.

This revision now requires changes to proceed.Sep 8 2022, 6:49 AM

Change empty string to null, return newThreadID to the previous position and add
conditional callback for onClick

web/chat/chat-thread-list-item.react.js
50–53 ↗	(On Diff #16503)	Can we use a `useCallback` here? Using memo when we have a function might be confusing. On the other hand, memo is a little more performant in this case... but still, I would prefer readability here.

This revision now requires changes to proceed.Sep 9 2022, 4:11 AM

Changing useMemo to useCallback

Adding @ashoat because he had some comments

web/chat/chat-thread-list-item.react.js
52 ↗	(On Diff #16540)	I think it might a little more readable if we used an alternative instead

Change if condition to alternative form

Harbormaster completed remote builds in B12053: Diff 16553.Sep 9 2022, 5:18 AM

Mostly feedback about naming

web/chat/chat-thread-composer.react.js
26 ↗	(On Diff #16553)	Nit: can we use American English instead of British English? "Behavior" instead of "behaviour"
26 ↗	(On Diff #16553)	"Renew" is confusing here... let's say `reset-active-thread` instead It appears that the reset will not occur if the active thread is not pending. How about `reset-active-thread-if-pending`?
web/chat/chat-thread-list-item.react.js
44–57 ↗	(On Diff #16553)	This too should've been a separate diff. It took a second for me to realize why it was necessary... it would've been helpful to have a separate diff name / diff description to explain why this change is necessary At this point you can feel free to leave it in
50 ↗	(On Diff #16553)	`conditionalClick` is not a very helpful name. How about `selectItemIfNotActiveCreation`
web/selectors/nav-selectors.js
144–158 ↗	(On Diff #16553)	These changes appear to have nothing to do with this diff. They should've been a separate diff, but at this point I won't object to leaving them here
