[eprh] Remove NoUnusedOptOutDirectives (#34703)
This rule was a leftover from a while ago and doesn't actually lint
anything useful. Specifically, you get a lint error if you try to opt
out a component that isn't already bailing out. If there's a bailout the
compiler already safely skips over it, so adding `'use no memo'` there
is unnecessary.

Fixes #31407

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.
