📝 Walkthrough

Summary by CodeRabbit

New Features
- Enhanced asynchronous data collection, enabling more efficient handling of data streams.
Refactor
- Improved promise management for clearer traceability, better resolution of nested asynchronous operations, and streamlined processing logic.

Walkthrough

The pull request introduces updates in both the @whatwg-node/promise-helpers and @whatwg-node/node-fetch packages. In the promise-helpers package, the fakePromise function signature is updated to return a more accurately awaited type, and inline callbacks in iterateAsync are replaced with named functions for better trace readability. In the node-fetch package, the PonyfillBody class now leverages the handleMaybePromise function to streamline asynchronous handling, and a changeset entry promotes using Array.fromAsync for asynchronous collections.

Changes

File(s)	Change Summary
`.changeset/loose-cities-grin.md` `packages/promise-helpers/src/index.ts`	Updates to `@whatwg-node/promise-helpers`: the `fakePromise` signature is modified to return `Promise<Awaited<T>>`, and the `iterateAsync` method now uses named functions (`handleCallback` and `handleCallbackResult`) for improved trace readability.
`.changeset/quiet-corners-tickle.md` `packages/node-fetch/src/Body.ts`	Patch for `@whatwg-node/node-fetch`: Introduces asynchronous collection with `Array.fromAsync` in the changeset and integrates `handleMaybePromise` in the `PonyfillBody` class to streamline promise handling in both async iterable and readable stream scenarios.

I'm a rabbit hopping through lines of code,
Named functions now in my humble abode.
Async promises neatly aligned in a row,
With streams and callbacks ready to go.
Code carrots await, and off we hop! 🥕🐰

🪧 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.
