* [useEvent] Lint for presence of useEvent functions in dependency lists With #25473, the identity of useEvent's return value is no longer stable across renders. Previously, the ExhaustiveDeps lint rule would only allow the omission of the useEvent function, but you could still add it as a dependency. This PR updates the ExhaustiveDeps rule to explicitly check for the presence of useEvent functions in dependency lists, and emits a warning and suggestion/autofixer for removing the dependency.
eslint-plugin-react-hooks
This ESLint plugin enforces the Rules of Hooks.
It is a part of the Hooks API 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:
# npm
npm install eslint-plugin-react-hooks --save-dev
# yarn
yarn add eslint-plugin-react-hooks --dev
Then extend the recommended eslint config:
{
"extends": [
// ...
"plugin:react-hooks/recommended"
]
}
Custom Configuration
If you want more fine-grained configuration, you can instead add a snippet like this to your ESLint configuration file:
{
"plugins": [
// ...
"react-hooks"
],
"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.
{
"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 documentation and the Hooks FAQ to learn more about this rule.
