This migrates the compiler's bundler to esbuild instead of rollup. Unlike React, our bundling use cases are far simpler since the majority of our packages are meant to be run on node. Rollup was adding considerable build time overhead whereas esbuild remains fast and has all the functionality we need out of the box. ### Before ``` time yarn workspaces run build yarn workspaces v1.22.22 > babel-plugin-react-compiler yarn run v1.22.22 $ rimraf dist && rollup --config --bundleConfigAsCjs src/index.ts → dist/index.js...

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
Add react-compiler to the plugins section of your .eslintrc 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.
