Changes

  • Wrap invocation of submit() in reset() using startTransition().

Why Changes are Needed

Otherwise the following error will be thrown:

An async function with useActionState was called outside of a transition. This is likely not what you intended (for example, isPending will not update correctly). Either call the returned function inside startTransition, or pass it to an `action` or `formAction` prop.

Versions:
NextJs v15.2.2
React v19.0.0

In any case, thanks for the great writeup!

Walkthrough

This pull request updates the reset function within the useResetableActionState hook. The function, which previously reset the state by directly calling submit(null), now wraps that call in a startTransition function. This change modifies the update scheduling by treating the reset as a transition. The hook’s overall structure and its returned values remain unchanged, and there are no modifications to exported or public entities.

Changes

File Change Summary
data/blog/reset-state-from-react-useactionstate.mdx Updated the reset function in the useResetableActionState hook to wrap submit(null) within startTransition, altering the state reset execution context.

Poem

I'm a rabbit with hops so bright,
Coding updates deep into the night.
Wrapped transitions now take the stage,
Resetting state with a gentle gauge.
Leaping through changes with a joyful heart,
In the code maze, I play my part!
🐰✨ Happy coding!

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
