fix: auto focus and scroll to bottom on large-text in composer #28790

jeet-dhandha · 2023-10-04T06:56:00Z

Details

In web the composer is not scrolling to bottom on large text when a report is opened or if page is refereshed.
We fixed the issue using UpdateMultilineInputRange.
Currently we scroll to each of the platform except iOS, as we don't have a good solution for it.

Fixed Issues

Reviewer Checklist

I have verified the author checklist is complete (all boxes are checked off).
I verified the correct issue is linked in the ### Fixed Issues section above
I verified testing steps are clear and they cover the changes made in this PR
- I verified the steps for local testing are in the Tests section
- I verified the steps for Staging and/or Production testing are in the QA steps section
- I verified the steps cover any possible failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
- I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
I checked that screenshots or videos are included for tests on all platforms
I included screenshots or videos for tests on all platforms
I verified tests pass on all platforms & I tested again on:
- Android / native
- Android / Chrome
- iOS / native
- iOS / Safari
- MacOS / Chrome / Safari
- MacOS / Desktop
If there are any errors in the console that are unrelated to this PR, I either fixed them (preferred) or linked to where I reported them in Slack
I verified proper code patterns were followed (see Reviewing the code)
- I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick).
- I verified that the left part of a conditional rendering a React component is a boolean and NOT a string, e.g. myBool && <MyComponent />.
- I verified that comments were added to code that is not self explanatory
- I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
- I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
- I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
- I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is approved by marketing by adding the Waiting for Copy label for a copy review on the original GH to get the correct copy.
- I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
- I verified the JSDocs style guidelines (in STYLE.md) were followed
If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
I verified that this PR follows the guidelines as stated in the Review Guidelines
I verified other components that can be impacted by these changes have been tested, and I retested again (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar have been tested & I retested again)
I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
I verified any variables that can be defined as constants (ie. in CONST.js or at the top of the file that uses the constant) are defined as such
If a new component is created I verified that:
- A similar component doesn't exist in the codebase
- All props are defined accurately and each prop has a /** comment above it */
- The file is named correctly
- The component has a clear name that is non-ambiguous and the purpose of the component can be inferred from the name alone
- The only data being stored in the state is data necessary for rendering and nothing else
- For Class Components, any internal methods passed to components event handlers are bound to this properly so there are no scoping issues (i.e. for onClick={this.submit} the method this.submit should be bound to this in the constructor)
- Any internal methods bound to this are necessary to be bound (i.e. avoid this.submit = this.submit.bind(this); if this.submit is never passed to a component event handler like onClick)
- All JSX used for rendering exists in the render method
- The component has the minimum amount of code necessary for its purpose, and it is broken down into smaller components in order to separate concerns and functions
If any new file was added I verified that:
- The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
If a new CSS style is added I verified that:
- A similar style doesn't already exist
- The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(themeColors.componentBG)
If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.
I have checked off every checkbox in the PR reviewer checklist, including those that don't apply to this PR.

@jeet-dhandha I'm still getting a delay before the composer scrolls to the bottom, presumably because you're wrapping with InteractionManager.runAfterInteractions. Unless there's a good reason for this that I don't understand, I much prefer the immediate scroll to bottom, feels a lot less janky!

jjcoffee · 2023-10-05T14:09:27Z

src/pages/home/report/ReportActionCompose/ComposerWithSuggestions.js

+
+        InteractionManager.runAfterInteractions(() => {
+            updateMultilineInputRange(textInputRef.current);
+            focus(); // This will focus the composer after its fully rendered.


Unsure why we need to force focus here?

App/src/pages/home/report/ReportActionCompose/ComposerWithSuggestions.js

Line 535 in f070f8b

autoFocus={shouldAutoFocusWithLongText}

If you check above line of code we are disabling autoFocus as we wan't to focus manually after scrollHeight and selection are updated.

So without that, the selection wouldn't be set to the end, is that what you mean? Or what side-effect is there if we don't add that?

Screen.Recording.2023-10-06.at.3.10.04.PM.mov

Without that Composer won't get Focused. As you can see the Cursor isn't there in the end.

Sorry this still isn't really making sense to me. If I remove your change to autoFocus and just have a simple useEffect that runs updateMultilineInputRange, it works fine (on desktop at least). I'm struggling to understand the reason why all this extra logic is necessary here.

Did you check out my video @jjcoffee ?

Lets have a quick chat in Slack here its harder to chat.

@jeet-dhandha Yes, is that with autoFocus set back to shouldAutoFocus? I don't get the same behaviour if so...

The original issue also doesn't show any problem with focusing on the composer. That's why I'm quite sceptical about adding extra focus calls here!

jjcoffee · 2023-10-05T14:11:10Z

@jeet-dhandha Can you please update the test steps to clarify that the text has to be long enough to make the scrollbar appear? It's also probably better to start with entering a long text and then refreshing, otherwise the steps are a bit confusing.

jjcoffee · 2023-10-05T14:18:20Z

@jeet-dhandha One last thing, can you make sure the screenshots follow the test steps? Not all of them seem to have a long enough text.

jeet-dhandha · 2023-10-05T16:48:05Z

True Enough @jjcoffee . InteractionManager was creating janky animation. After Removing it its a lot smoother.

@jeet-dhandha My point was that if I remove all of your code (including the autoFocus change) and just leave a simple useEffect that runs updateMultilineInputRange, it works fine (on desktop at least). I understand that with the autoFocus change you made, it's necessary to run focus(). I'm seeking clarification from you as to why the autoFocus change is there at all?

jeet-dhandha · 2023-10-09T16:33:48Z

WTH 😵‍💫 it was not working previously as the scroll to bottom animation was coming. But now its working probably due to the removal on InteractionsManager.

@jjcoffee Removing all the unnecessary code.

@jjcoffee Please review last time 😄

I don't think initialFocusedRef is needed anymore since we removed focus calls.

I don't think the isNativeApp check is really necessary here either. Also not sure if you considered under what cases shouldAutoFocus would be false and if we'd not want to scroll to the bottom? It seems to me like we always want to be scrolled to the bottom, but I could be missing some obvious case!

jjcoffee · 2023-10-10T15:46:39Z

@jeet-dhandha As it stands, it doesn't look like we scroll to the bottom on mWeb which I don't think makes sense as you most likely want to continue from the end of your last message, rather than the top (even if we're not focused on the composer!).

Please check now. @jjcoffee

Hmm I see what you mean, can you check the behaviour?

jeet-dhandha · 2023-10-11T14:38:14Z

Yes it focuses it.

jeet-dhandha · 2023-10-11T14:40:19Z

There's a hack which i think we can use, but i don't recommend it.

Screen.Recording.2023-10-11.at.8.08.52.PM.mov

jjcoffee · 2023-10-11T15:10:35Z

Hmm so I think we'll probably need to do the same as on the issue that introduced updateMultilineInputRange and ignore iOS for now as there isn't really a good solution to fix scrolling to the bottom of the input. Looping in @nkuoch here to see if you agree?

Note there's a very old RN issue from 2020 related to this. We could open an issue to see if anyone has a proposal to fix that issue as it would unlock the fix for both this and all pages that rely on updateMultilineInputRange.

jjcoffee · 2023-10-12T11:49:58Z

@jeet-dhandha Could you ensure that iOS doesn't focus on composer, maybe by adding a shouldFocus property to updateMultilineInputRange?

jeet-dhandha · 2023-10-12T17:41:34Z

Added shouldAutoFocus check and below is the output.
