Rob Hogan c9c601d61a Node.js: Drop support for Node.js versions released before 20.19.4, and EOL v21,v23 (#55114)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/55114

Our official [docs](https://reactnative.dev/docs/set-up-your-environment#node--watchman) require:

> Node 20.19.4 or newer

Currently, our `package.json#engines` fields express this as `"node": ">= 20.19.4"`

This is a bit imprecise because of Node's overlapping release lines - e.g. v24.0.0 is actually older than v20.19.4 (2025-07-15), and the whole v21 line was already EOL before v20.19.4.

The release *date* is relevant because Node.js frequently backports the most important updates - notably, `require(esm)` is already stable in Node 20.19 but is not unflagged in v22 until v22.12.

This makes the `package.json#engines` requirement truer to the documented requirement, dropping some old minors and EOL majors that prevent us using features included in v20.19.

Notably, `require(esm)` is stable and unflagged on all versions supported from this diff.

 - v21 and v23 are EOL, so are dropped.
 - v22.13 pre-dates 20.19.4 and is the first to have unflagged silent `require(esm)`
 - v24.3.0 pre-dates 20.19.4 and is the first to unflag TS-stripping
 - Support v25 and newer.

Changelog:
[General][Breaking] Drop support for EOL Node.js lines and old minors.

Danger

Danger is a JavaScript runtime which helps you provide continuous feedback inside GitHub. It's used inside Github Actions to analyze the contents of a GitHub pull request.

If you want to test changes to Danger, I'd recommend checking out an existing PR and then running the danger pr command. You'll need a GitHub Public Access Token (PAT). It will look like github_pat_<REDACTED>.

So, for example:

cd private/react-native-bots && yarn
DANGER_GITHUB_API_TOKEN=ghp_<REDACTED> yarn danger pr https://github.com/facebook/react-native/pull/1234

Code Analysis Bot

The code analysis bot provides lint and other results as inline reviews on GitHub. It runs as part of the Circle CI analysis workflow.

If you want to test changes to the Code Analysis Bot, I'd recommend checking out an existing PR and then running the analyze pr command. You'll need a GitHub token. You can re-use this one: 312d354b5c36f082cfe9 07973d757026bdd9f196 (just remove the space). So, for example:

GITHUB_TOKEN=[ENV_ABOVE] GITHUB_PR_NUMBER=1234 yarn lint-ci
