eslint-config-wojtekmaj

eslint-config-wojtekmaj

Set of default, recommended rules from:

• ESLint itself,
• eslint-plugin-import,
• eslint-plugin-jsx-a11y,
• eslint-plugin-react,
• eslint-plugin-react-hooks

with a few enhancements:

• All required plugins are marked as dependencies, not peerDependencies, so you don't need to install them manually. Note: Since ESLint 8.0.0, it will work just fine with Yarn PnP.
• Files matching **/*.spec.js', **/*.spec.jsx, **/__tests__/* patterns automatically detect jest environment, so you can use test, describe, it, expect globals.
• Certain rules were overwritten (details below).
• React flavor assumes JSX automatic runtime is turned on.

This config is designed to be run alongside Prettier.
