# `eslint-plugin-react-hooks`
|
|
|
|
This ESLint plugin enforces the [Rules of Hooks](https://react.dev/reference/rules/rules-of-hooks).
|
|
|
|
It is a part of the [Hooks API](https://react.dev/reference/react/hooks) for React.
|
|
|
|
## Installation
|
|
|
|
**Note: If you're using Create React App, please use `react-scripts` >= 3 instead of adding it directly.**
|
|
|
|
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
|
|
```
|
|
|
|
### Legacy Config (.eslintrc)
|
|
|
|
If you are still using ESLint below 9.0.0, please continue to use `recommended-legacy`. To avoid breaking changes, we still support `recommended` as well, but note that this will be changed to alias the flat recommended config in v6.
|
|
|
|
```js
|
|
{
|
|
"extends": [
|
|
// ...
|
|
"plugin:react-hooks/recommended-legacy"
|
|
]
|
|
}
|
|
```
|
|
|
|
### Flat Config (eslint.config.js)
|
|
|
|
For [ESLint 9.0.0 and above](https://eslint.org/blog/2024/04/eslint-v9.0.0-released/) users, add the `recommended-latest` config.
|
|
|
|
```js
|
|
import reactHooks from 'eslint-plugin-react-hooks';
|
|
|
|
export default [
|
|
// ...
|
|
reactHooks.configs['recommended-latest'],
|
|
];
|
|
```
|
|
|
|
### Custom Configuration
|
|
|
|
If you want more fine-grained configuration, you can instead add a snippet like this to your ESLint configuration file:
|
|
|
|
#### Legacy Config (.eslintrc)
|
|
|
|
```js
|
|
{
|
|
"plugins": [
|
|
// ...
|
|
"react-hooks"
|
|
],
|
|
"rules": {
|
|
// ...
|
|
"react-hooks/rules-of-hooks": "error",
|
|
"react-hooks/exhaustive-deps": "warn"
|
|
}
|
|
}
|
|
```
|
|
|
|
#### Flat Config (eslint.config.js)
|
|
|
|
```js
|
|
import reactHooks from 'eslint-plugin-react-hooks';
|
|
|
|
export default [
|
|
{
|
|
files: ['**/*.{js,jsx}'],
|
|
plugins: { 'react-hooks': reactHooks },
|
|
// ...
|
|
rules: {
|
|
'react-hooks/rules-of-hooks': 'error',
|
|
'react-hooks/exhaustive-deps': '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.
|
|
|
|
