eslint-plugin-react-component-name

Motivation

• Autofix based on variable name.
• Better error traces in console for debug.
• Support for any High-order components and compositions (e.g. MobX's observer or nesting like memo(forwardRef(() => <div />)))
• Universal solution based solely on ESLint.

Installation

Install the package using npm or yarn:

npm install eslint-plugin-react-component-name --save-dev

Usage

Add the plugin to your .eslintrc configuration:

{
  "plugins": ["react-component-name"],
  "extends": ["plugin:react-component-name/recommended"]
}

You can change the default rule setting (memo, forwardRef) by adding targets option in the rules section.

Also, if you are using "prefer-arrow-callback" rule, it is required to add allowNamedFunctions option to it.

{
  "plugins": ["react-component-name"],
  "rules": {
    "prefer-arrow-callback": ["error", { "allowNamedFunctions": true }],

    "react-component-name/react-component-name": [
      "error",
      {
        "targets": ["memo", "forwardRef", "observer"]
      }
    ]
  }
}

Examples

Wrong Code

const MyComponent = memo(() => {
  return <div>Hello</div>;
});

const MyRef = forwardRef((props, ref) => {
  return <input ref={ref} {...props} />;
});

Fixed Code

const MyComponent = memo(function MyComponent() {
  return <div>Hello</div>;
});

const MyRef = forwardRef(function MyRef(props, ref) {
  return <input ref={ref} {...props} />;
});
