eslint-plugin-react-app

library6.2.2jsnpmunverified

ESLint configuration and rules bundle based on Create React App's eslint-config-react-app. Version 6.2.2 wraps eslint-config-react-app 5.2.1 and includes plugins for import, flowtype, JSX-a11y, React, React Hooks, and TypeScript. Designed as a single-dependency drop-in for CRA-style linting without manually installing each sub-plugin. Works in React Native. Requires ESLint 6.x peer dependency. Release cadence is sporadic, tied to upstream CRA config updates.

Verified usage

plugin:react-app/recommended

✓ extends: ['plugin:react-app/recommended'] in .eslintrc

✗ extends: ['eslint:recommended', 'plugin:react-app/recommended'] (double extends, but not wrong per se; common mistake is omitting 'plugin:' prefix)

Main exported config; use as a string in ESLint extends array.

react-app/react/react-in-jsx-scope

✓ 'react-app/react/react-in-jsx-scope': ['warn'] in rules

✗ 'react/react-in-jsx-scope': ['warn'] (missing 'react-app/' prefix) leads to 'Definition for rule 'react/react-in-jsx-scope' was not found'

All rules from included plugins must be namespaced with 'react-app/' to avoid collisions.

react-app

✓ extends: ['react-app'] (also works without 'plugin:' prefix for the base config)

✗ extends: 'react-app' (missing array brackets - ESLint accepts string, but common mistake is using wrong key 'plugins' instead of 'extends')

Both 'react-app' and 'plugin:react-app/recommended' are valid. The latter is recommended for clarity.

Installs eslint and the plugin, then configures ESLint to use the CRA recommended rules and override one rule.

// Install npm install --save-dev eslint eslint-plugin-react-app@6.2.2 // .eslintrc.json { "extends": ["plugin:react-app/recommended"], "rules": { "react-app/react/react-in-jsx-scope": ["warn"] } } // Then lint: npx eslint src/

Debug

Known issues

gotchaAll rules from sub-plugins must be prefixed with 'react-app/' to avoid 'Definition for rule not found' errors.

fix

Prefix any rule from eslint-plugin-import, eslint-plugin-react, etc. with 'react-app/', e.g., 'react-app/react/jsx-uses-react'.

affects: >=5.0.0

breakingVersion 6.0.0 updated eslint-config-react-app to 5.0.0, which may include breaking rule changes (e.g., new TypeScript rules).

fix

Review changelog of eslint-config-react-app for rule changes; adjust your overrides.

affects: >=6.0.0 <7.0.0

deprecatedThis plugin is not maintained by the CRA team; it may lag behind upstream eslint-config-react-app updates.

fix

Consider using @rushstack/eslint-config or direct eslint-config-react-app with all peer deps for official support.

affects: *

gotchaRequires ESLint 6.x; incompatible with ESLint 7+.

fix

Stay on ESLint 6.x or use later version of eslint-plugin-react-app if available (currently none). Check peerDependencies.

affects: >=6.0.0

Errors

Common errors & fixes

Error: Failed to load plugin 'react-app' declared in '.eslintrc.json': Cannot find module 'eslint-plugin-react-app'

Plugin package not installed or not in node_modules.

fix

Run `npm install --save-dev eslint-plugin-react-app` and ensure it's in package.json.

Error: Definition for rule 'react/react-in-jsx-scope' was not found

Rule name without 'react-app/' prefix.

fix

Use 'react-app/react/react-in-jsx-scope' instead.

ESLint couldn't find the plugin "eslint-plugin-import".

The plugin only includes eslint-config-react-app but not its sub-plugins as direct deps? Actually they are bundled. This error appears if eslint cache is stale or install corrupted.

fix

Delete node_modules and package-lock.json, then reinstall.

TypeError: Cannot read property 'some' of undefined (eslint-plugin-import)

Incompatible ESLint version (e.g., ESLint 7).

fix

Downgrade ESLint to 6.x: `npm install --save-dev eslint@6`.
