Walkthrough

The changes in this pull request involve the addition of the TransformStream import from node:stream/web to the src/utils.ts file. The patchForNode16 function is updated to check for the existence of global.TransformStream, adding a polyfill if it is not defined. This update aims to enhance compatibility with Node.js 16 without altering existing function signatures or overall control flow.

Changes

File	Change Summary
src/utils.ts	Added import for `TransformStream` from `node:stream/web` and updated `patchForNode16` to check for `global.TransformStream`.

Poem

In the code where streams do flow,
A new transform joins the show.
With checks in place, it finds its home,
In Node 16, it loves to roam.
So let us cheer, with hops and glee,
For streams that dance so joyfully! 🐇✨

- 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.

219-223: Consider adding tests for the TransformStream polyfill

The new polyfill functionality should be covered by tests to ensure it works correctly across different Node.js versions.

Would you like me to help create test cases for verifying the TransformStream polyfill functionality?

4-4: LGTM: Import statement follows Node.js best practices

The addition of TransformStream to the import statement is correct and follows Node.js best practices by using the node: protocol prefix.

219-223: Verify the TransformStream polyfill compatibility

The implementation follows the established pattern for Web Streams API polyfills. However, we should verify:

The polyfill works correctly on Node.js 16
This change doesn't affect other Node.js versions unexpectedly

Let's verify the Node.js version compatibility:
