Two additional validations for useMemo: * Disallow reassigning to values declared outside the useMemo callback (always on) * Disallow unused useMemo calls (part of the validateNoVoidUseMemo feature flag, which in turn is off by default) We should probably enable this flag though! --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

eslint-plugin-react-compiler
ESLint plugin surfacing problematic React code found by the React compiler.
Installation
You'll first need to install ESLint:
npm i eslint --save-dev
Next, install eslint-plugin-react-compiler:
npm install eslint-plugin-react-compiler --save-dev
Usage
Flat config
Edit your eslint 8+ config (for example eslint.config.mjs) with the recommended configuration:
+ import reactCompiler from "eslint-plugin-react-compiler"
import react from "eslint-plugin-react"
export default [
// Your existing config
{ ...pluginReact.configs.flat.recommended, settings: { react: { version: "detect" } } },
+ reactCompiler.configs.recommended
]
Legacy config (.eslintrc)
Add react-compiler to the plugins section of your configuration file. You can omit the eslint-plugin- prefix:
{
"plugins": [
"react-compiler"
]
}
Then configure the rules you want to use under the rules section.
{
"rules": {
"react-compiler/react-compiler": "error"
}
}
Rules
TODO: Run eslint-doc-generator to generate the rules list.
