|
|---|
| 12 | ## Installation
|
|---|
| 13 |
|
|---|
| 14 | ```sh
|
|---|
| 15 | npm install eslint eslint-plugin-react --save-dev
|
|---|
| 16 | ```
|
|---|
| 17 |
|
|---|
| 18 | It is also possible to install ESLint globally rather than locally (using `npm install -g eslint`). However, this is not recommended, and any plugins or shareable configs that you use must be installed locally in either case.
|
|---|
| 19 |
|
|---|
| 20 | ## Configuration (legacy: `.eslintrc*`) <a id="configuration"></a>
|
|---|
| 21 |
|
|---|
| 22 | Use [our preset](#recommended) to get reasonable defaults:
|
|---|
| 23 |
|
|---|
| 24 | ```json
|
|---|
| 25 | "extends": [
|
|---|
| 26 | "eslint:recommended",
|
|---|
| 27 | "plugin:react/recommended"
|
|---|
| 28 | ]
|
|---|
| 29 | ```
|
|---|
| 30 |
|
|---|
| 31 | If you are using the [new JSX transform from React 17](https://reactjs.org/blog/2020/09/22/introducing-the-new-jsx-transform.html#removing-unused-react-imports), extend [`react/jsx-runtime`](https://github.com/jsx-eslint/eslint-plugin-react/blob/c8917b0885094b5e4cc2a6f613f7fb6f16fe932e/index.js#L163-L176) in your eslint config (add `"plugin:react/jsx-runtime"` to `"extends"`) to disable the relevant rules.
|
|---|
| 32 |
|
|---|
| 33 | You should also specify settings that will be shared across all the plugin rules. ([More about eslint shared settings](https://eslint.org/docs/user-guide/configuring/configuration-files#adding-shared-settings))
|
|---|
| 34 |
|
|---|
| 35 | ```json5
|
|---|
| 36 | {
|
|---|
| 37 | "settings": {
|
|---|
| 38 | "react": {
|
|---|
| 39 | "createClass": "createReactClass", // Regex for Component Factory to use,
|
|---|
| 40 | // default to "createReactClass"
|
|---|
| 41 | "pragma": "React", // Pragma to use, default to "React"
|
|---|
| 42 | "fragment": "Fragment", // Fragment to use (may be a property of <pragma>), default to "Fragment"
|
|---|
| 43 | "version": "detect", // React version. "detect" automatically picks the version you have installed.
|
|---|
| 44 | // You can also use `16.0`, `16.3`, etc, if you want to override the detected value.
|
|---|
| 45 | // Defaults to the "defaultVersion" setting and warns if missing, and to "detect" in the future
|
|---|
| 46 | "defaultVersion": "", // Default React version to use when the version you have installed cannot be detected.
|
|---|
| 47 | // If not provided, defaults to the latest React version.
|
|---|
| 48 | "flowVersion": "0.53" // Flow version
|

|
|---|
| 50 | "propWrapperFunctions": [
|
|---|
| 51 | // The names of any function used to wrap propTypes, e.g. `forbidExtraProps`. If this isn't set, any propTypes wrapped in a function will be skipped.
|
|---|
| 52 | "forbidExtraProps",
|
|---|
| 53 | {"property": "freeze", "object": "Object"},
|
|---|
| 54 | {"property": "myFavoriteWrapper"},
|
|---|
| 55 | // for rules that check exact prop wrappers
|
|---|
| 56 | {"property": "forbidExtraProps", "exact": true}
|
|---|
| 57 | ],
|
|---|
| 58 | "componentWrapperFunctions": [
|
|---|
| 59 | // The name of any function used to wrap components, e.g. Mobx `observer` function. If this isn't set, components wrapped by these functions will be skipped.

|
|---|
| 63 | {"property": "observer", "object": "<pragma>"} // sets `object` to whatever value `settings.react.pragma` is set to
|
|---|
| 64 | ],
|
|---|
| 65 | "formComponents": [
|
|---|
| 66 | // Components used as alternatives to <form> for forms, eg. <Form endpoint={ url } />
|
|---|
| 67 | "CustomForm",
|
|---|
| 68 | {"name": "SimpleForm", "formAttribute": "endpoint"},
|
|---|
| 69 | {"name": "Form", "formAttribute": ["registerEndpoint", "loginEndpoint"]}, // allows specifying multiple properties if necessary
|
|---|
| 70 | ],
|
|---|
| 71 | "linkComponents": [
|
|---|
| 72 | // Components used as alternatives to <a> for linking, eg. <Link to={ url } />
|
|---|
| 73 | "Hyperlink",

|---|
| 74 | {"name": "MyLink", "linkAttribute": "to"},
|
|---|
| 75 | {"name": "Link", "linkAttribute": ["to", "href"]}, // allows specifying multiple properties if necessary
|
|---|
| 76 | ]
|
|---|
| 77 | }
|
|---|
| 78 | }
|
|---|
| 79 | ```
|
|---|
| 80 |
|
|---|
| 81 | If you do not use a preset you will need to specify individual rules and add extra configuration.
|
|---|
| 82 |
|
|---|
| 83 | Add "react" to the plugins section.
|
|---|
| 84 |
|
|---|
| 85 | ```json
|
|---|
| 86 | {
|
|---|
| 87 | "plugins": [
|
|---|
| 88 | "react"
|
|---|
| 89 | ]
|
|---|
| 90 | }
|
|---|
| 91 | ```
|
|---|
| 92 |
|
|---|
| 93 | Enable JSX support.
|
|---|
| 94 |
|
|---|
| 95 | With `eslint` 2+
|
|---|
| 96 |
|
|---|
| 97 | ```json
|
|---|
| 98 | {
|
|---|
| 99 | "parserOptions": {
|
|---|
| 100 | "ecmaFeatures": {
|
|---|
| 101 | "jsx": true
|
|---|
| 102 | }
|
|---|
| 103 | }
|
|---|
| 104 | }
|
|---|
| 105 | ```
|
|---|
| 106 |
|
|---|
| 107 | Enable the rules that you would like to use.
|
|---|
| 108 |
|
|---|
| 109 | ```json
|
|---|
| 110 | "rules": {
|
|---|
| 111 | "react/jsx-uses-react": "error",
|
|---|
| 112 | "react/jsx-uses-vars": "error",
|
|---|
| 113 | }
|
|---|
| 114 | ```
|
|---|
| 115 |
|
|---|
| 116 | ### Shareable configs
|
|---|
| 117 |
|
|---|
| 118 | #### Recommended
|
|---|
| 119 |
|
|---|
| 120 | This plugin exports a `recommended` configuration that enforces React good practices.
|
|---|
| 121 |
|
|---|
| 122 | To enable this configuration use the `extends` property in your `.eslintrc` config file:
|
|---|
| 123 |
|
|---|
| 124 | ```json
|
|---|
| 125 | {
|
|---|
| 126 | "extends": ["eslint:recommended", "plugin:react/recommended"]
|
|---|
| 127 | }
|
|---|
| 128 | ```
|
|---|
| 129 |
|
|---|
| 130 | See [`eslint` documentation](https://eslint.org/docs/user-guide/configuring/configuration-files#extending-configuration-files) for more information about extending configuration files.
|
|---|
| 131 |
|
|---|
| 132 | #### All
|
|---|
| 133 |
|
|---|
| 134 | This plugin also exports an `all` configuration that includes every available rule.
|
|---|
| 135 | This pairs well with the `eslint:all` rule.
|
|---|
| 136 |
|
|---|
| 137 | ```json
|
|---|
| 138 | {
|
|---|
| 139 | "plugins": [
|
|---|
| 140 | "react"
|
|---|
| 141 | ],
|
|---|
| 142 | "extends": ["eslint:all", "plugin:react/all"]
|
|---|
| 143 | }
|
|---|
| 144 | ```
|
|---|
| 145 |
|
|---|
| 146 | **Note**: These configurations will import `eslint-plugin-react` and enable JSX in [parser options](https://eslint.org/docs/user-guide/configuring/language-options#specifying-parser-options).
|
|---|
| 147 |
|
|---|
| 148 | ## Configuration (new: `eslint.config.js`)
|
|---|
| 149 |
|
|---|
| 150 | From [`v8.21.0`](https://github.com/eslint/eslint/releases/tag/v8.21.0), eslint announced a new config system.
|
|---|
| 151 | In the new system, `.eslintrc*` is no longer used. `eslint.config.js` would be the default config file name.
|
|---|
| 152 | In eslint `v8`, the legacy system (`.eslintrc*`) would still be supported, while in eslint `v9`, only the new system would be supported.
|
|---|
| 153 |
|
|---|
| 154 | And from [`v8.23.0`](https://github.com/eslint/eslint/releases/tag/v8.23.0), eslint CLI starts to look up `eslint.config.js`.
|
|---|
| 155 | **So, if your eslint is `>=8.23.0`, you're 100% ready to use the new config system.**

|
|---|
| 165 | ### Plugin
|
|---|
| 166 |
|
|---|
| 167 | The default export of `eslint-plugin-react` is a plugin object.
|
|---|
| 168 |
|
|---|
| 169 | ```js
|
|---|
| 170 | const react = require('eslint-plugin-react');
|
|---|
| 171 | const globals = require('globals');
|
|---|
| 172 |
|
|---|
| 173 | module.exports = [
|
|---|
| 174 | …
|
|---|
| 175 | {
|
|---|
| 176 | files: ['**/*.{js,jsx,mjs,cjs,ts,tsx}'],
|
|---|
| 177 | plugins: {
|
|---|
| 178 | react,
|
|---|
| 179 | },
|
|---|
| 180 | languageOptions: {
|
|---|
| 181 | parserOptions: {
|
|---|
| 182 | ecmaFeatures: {
|
|---|
| 183 | jsx: true,
|
|---|
| 184 | },
|
|---|
| 185 | },
|
|---|
| 186 | globals: {
|
|---|
| 187 | ...globals.browser,
|
|---|
| 188 | },
|
|---|
| 189 | },
|
|---|
| 190 | rules: {
|
|---|
| 191 | // ... any rules you want
|
|---|
| 192 | 'react/jsx-uses-react': 'error',
|
|---|
| 193 | 'react/jsx-uses-vars': 'error',
|
|---|
| 194 | },
|
|---|
| 195 | // ... others are omitted for brevity
|
|---|
| 196 | },
|
|---|
| 197 | …
|
|---|
| 198 | ];
|
|---|
| 199 | ```
|
|---|
| 200 |
|
|---|
| 201 | ### Configuring shared settings
|
|---|
| 202 |
|
|---|
| 203 | Refer to the [official docs](https://eslint.org/docs/latest/user-guide/configuring/configuration-files-new#configuring-shared-settings).
|
|---|
| 204 |
|
|---|
| 205 | The schema of the `settings.react` object would be identical to that of what's already described above in the legacy config section.
|
|---|
| 206 |
|
|---|
| 207 | <!-- markdownlint-disable-next-line no-duplicate-heading -->
|
|---|
| 208 | ### Flat Configs
|
|---|
| 209 |
|
|---|
| 210 | This plugin exports 3 flat configs:
|
|---|
| 211 |
|
|---|
| 212 | - `flat.all`
|
|---|
| 213 | - `flat.recommended`
|
|---|
| 214 | - `flat['jsx-runtime']`
|
|---|
| 215 |
|
|---|
| 216 | The flat configs are available via the root plugin import. They will configure the plugin under the `react/` namespace and enable JSX in [`languageOptions.parserOptions`](https://eslint.org/docs/latest/use/configure/language-options#specifying-parser-options).
|
|---|
| 217 |
|
|---|
| 218 | ```js
|
|---|
| 219 | const reactPlugin = require('eslint-plugin-react');
|
|---|
| 220 |
|
|---|
| 221 | module.exports = [
|
|---|
| 222 | …
|
|---|
| 223 | reactPlugin.configs.flat.recommended, // This is not a plugin object, but a shareable config object
|
|---|
| 224 | …
|
|---|
| 225 | ];
|
|---|
| 226 | ```
|
|---|
| 227 |
|
|---|
| 228 | You can of course add/override some properties.
|
|---|
| 229 |
|
|---|
| 230 | **Note**: Our shareable configs does not preconfigure `files` or [`languageOptions.globals`](https://eslint.org/docs/latest/user-guide/configuring/configuration-files-new#configuration-objects).
|
|---|
| 231 | For most of the cases, you probably want to configure some properties by yourself.
|
|---|
| 232 |
|
|---|
| 233 | ```js
|
|---|
| 234 | const reactPlugin = require('eslint-plugin-react');
|
|---|
| 235 | const globals = require('globals');
|
|---|
| 236 |
|
|---|
| 237 | module.exports = [
|
|---|
| 238 | …
|
|---|
| 239 | {
|
|---|
| 240 | files: ['**/*.{js,mjs,cjs,jsx,mjsx,ts,tsx,mtsx}'],
|
|---|
| 241 | ...reactPlugin.configs.flat.recommended,
|
|---|
| 242 | languageOptions: {
|
|---|
| 243 | ...reactPlugin.configs.flat.recommended.languageOptions,
|
|---|
| 244 | globals: {
|
|---|
| 245 | ...globals.serviceworker,
|
|---|
| 246 | ...globals.browser,
|
|---|
| 247 | },
|
|---|
| 248 | },
|
|---|
| 249 | },
|
|---|
| 250 | …
|
|---|
| 251 | ];
|
|---|
| 252 | ```
|
|---|
| 253 |
|
|---|
| 254 | The above example is same as the example below, as the new config system is based on chaining.
|
|---|
| 255 |
|
|---|
| 256 | ```js
|
|---|
| 257 | const reactPlugin = require('eslint-plugin-react');
|
|---|
| 258 | const globals = require('globals');
|
|---|
| 259 |
|
|---|
| 260 | module.exports = [
|
|---|
| 261 | …
|
|---|
| 262 | {
|
|---|
| 263 | files: ['**/*.{js,mjs,cjs,jsx,mjsx,ts,tsx,mtsx}'],
|
|---|
| 264 | ...reactPlugin.configs.flat.recommended,
|
|---|
| 265 | },
|
|---|
| 266 | {
|
|---|
| 267 | files: ['**/*.{js,mjs,cjs,jsx,mjsx,ts,tsx,mtsx}'],
|
|---|
| 268 | languageOptions: {
|
|---|
| 269 | globals: {
|
|---|
| 270 | ...globals.serviceworker,
|
|---|
| 271 | ...globals.browser,
|
|---|
| 272 | },
|
|---|
| 273 | },
|
|---|
| 274 | },
|
|---|
| 275 | …
|
|---|
| 276 | ];
|
|---|
| 277 | ```
