eslint-plugin-jest-react

library0.1.0jsnpmunverified

An ESLint plugin providing linting rules for Jest tests in React projects. Current stable version is 0.1.0, with low release cadence (last update likely stale). Key differentiator: combines Jest and React specific rules. However, the official community ESLint Jest plugin (eslint-plugin-jest) is more actively maintained and recommended; this plugin may have niche value only for the `no-mocking-react` rule.

plugin:jest-react/recommended

✓ extends: ['plugin:jest-react/recommended']

✗ plugins: ['jest-react'] without extends

Use the recommended config to enable all rules with sensible defaults.

Rules (e.g., jest-react/no-mocking-react)

✓ { "rules": { "jest-react/no-mocking-react": "warn" } }

✗ plugins: ['jest-react'] but not adding rules

Rules are prefixed with 'jest-react/' in ESLint configs.

Plugin declaration

✓ plugins: ['jest-react']

✗ plugins: ['eslint-plugin-jest-react']

ESLint automatically shortens the plugin name; you only need 'jest-react'.

Shows how to install and configure the plugin in ESLint to lint Jest tests in React projects.

// Install: yarn add --dev eslint eslint-plugin-jest-react // .eslintrc.js module.exports = { plugins: ['jest-react'], extends: ['plugin:jest-react/recommended'], rules: { 'jest-react/no-mocking-react': 'error' } };
