# `eslint-plugin-react-hooks`
|
|
|
|
The official ESLint plugin for [React](https://react.dev) which enforces the [Rules of React](https://react.dev/reference/eslint-plugin-react-hooks) and other best practices.
|
|
|
|
## Installation
|
|
|
|
Assuming you already have ESLint installed, run:
|
|
|
|
```sh
|
|
# npm
|
|
npm install eslint-plugin-react-hooks --save-dev
|
|
|
|
# yarn
|
|
yarn add eslint-plugin-react-hooks --dev
|
|
```
|
|
|
|
### Flat Config (eslint.config.js|ts)
|
|
|
|
Add the `recommended` config for all recommended rules:
|
|
|
|
```js
|
|
// eslint.config.js
|
|
import reactHooks from 'eslint-plugin-react-hooks';
|
|
import { defineConfig } from 'eslint/config';
|
|
|
|
export default defineConfig([
|
|
reactHooks.configs.flat.recommended,
|
|
]);
|
|
```
|
|
|
|
If you want to try bleeding edge experimental compiler rules, use `recommended-latest`.
|
|
|
|
```js
|
|
// eslint.config.js
|
|
import reactHooks from 'eslint-plugin-react-hooks';
|
|
import { defineConfig } from 'eslint/config';
|
|
|
|
export default defineConfig([
|
|
reactHooks.configs.flat['recommended-latest'],
|
|
]);
|
|
```
|
|
|
|
### Legacy Config (.eslintrc)
|
|
|
|
If you are still using ESLint below 9.0.0, the `recommended` preset can also be used to enable all recommended rules.
|
|
|
|
```js
|
|
{
|
|
"extends": ["plugin:react-hooks/recommended"],
|
|
// ...
|
|
}
|
|
|
|
```
|
|
|
|
### Custom Configuration
|
|
|
|
If you want more fine-grained configuration, you can instead choose to enable specific rules. However, we strongly encourage using the recommended presets — see above — so that you will automatically receive new recommended rules as we add them in future versions of the plugin.
|
|
|
|
#### Flat Config (eslint.config.js|ts)
|
|
|
|
```js
|
|
import reactHooks from 'eslint-plugin-react-hooks';
|
|
|
|
export default [
|
|
{
|
|
files: ['**/*.{js,jsx}'],
|
|
plugins: { 'react-hooks': reactHooks },
|
|
// ...
|
|
rules: {
|
|
// Core hooks rules
|
|
'react-hooks/rules-of-hooks': 'error',
|
|
'react-hooks/exhaustive-deps': 'warn',
|

}
|
|

#### Legacy Config (.eslintrc)
|
|

|
|
"plugins": [
|
|
// ...
|
|
"react-hooks"
|
|
],
|

|
"react-hooks/use-memo": "error",
|
|
"react-hooks/incompatible-library": "warn"
|
|
}
|
|
}
|
|
```
|
|
|
|
## Advanced Configuration
|
|
|
|
`exhaustive-deps` can be configured to validate dependencies of custom Hooks with the `additionalHooks` option.
|
|
This option accepts a regex to match the names of custom Hooks that have dependencies.
|
|
|
|
```js
|
|
{
|
|
rules: {
|
|
// ...
|
|
"react-hooks/exhaustive-deps": ["warn", {
|
|
additionalHooks: "(useMyCustomHook|useMyOtherCustomHook)"
|
|
}]
|
|
}
|
|
}
|
|
```
|
|
|
|
We suggest to use this option **very sparingly, if at all**. Generally saying, we recommend most custom Hooks to not use the dependencies argument, and instead provide a higher-level API that is more focused around a specific use case.
|
|
|
|
## Valid and Invalid Examples
|
|
|
|
Please refer to the [Rules of Hooks](https://react.dev/reference/rules/rules-of-hooks) documentation to learn more about this rule.
