JavaScript ESLint rules

JavaScript ESLint bundle with best practices and common use rules for writing more consistent code

"semi": [ "error", "never" ] :godmode: ... the horror :goberserk:

Other bundles: XO, eslint-config-airbnb, eslint-config-google, more


npm install eslint @mutant-ws/eslint-config --save-dev

Run npm info "@mutant-ws/eslint-config@latest" peerDependencies to get the packages needed in your own devDependencies in package.json.

It should be something like:

"eslint": "^7.4.0",
"eslint-config-prettier": "^6.11.0",
"eslint-plugin-import": "^2.22.0",
"eslint-plugin-json": "^2.1.1",
"eslint-plugin-no-inferred-method-name": "^2.0.0",
"eslint-plugin-promise": "^4.2.1",
"eslint-plugin-prettier": "^3.1.4",
"eslint-plugin-unicorn": "^20.1.0",
"prettier": "^2.0.5"

For React projects you'll also have to add:

"eslint-plugin-html": "^6.0.2",
"eslint-plugin-react": "^7.20.3",
"eslint-plugin-react-hooks": "^4.0.8",


Add react, html or node target file in your .eslintrc file:

    "extends": [


  • eslint-plugin-import - Support for ES2015+ (ES6+) import/export syntax
  • eslint-plugin-promise - Enforce best practices for JavaScript promises
  • eslint-plugin-unicorn - Various awesome ESLint rules
  • eslint-plugin-html - Allows linting and fixing inline scripts contained in HTML files
  • eslint-plugin-react - React specific linting rules
  • eslint-plugin-react-hooks - Linting rules rules of React Hooks.
  • eslint-plugin-no-inferred-method-name - In ES6, compact methods and unnamed function expression assignments within object literals do not create a lexical identification (name) binding that corresponds to the function name identifier for recursion or event binding. The compact method syntax will not be an appropriate option for these types of solutions, and a named function expression should be used instead. This custom ESLint rule will identify instances where a function name is being called and a lexical identifier is unavailable within a compact object literal.

Example config

Using babel-eslint and eslint-import-resolver-webpack


    "root"  : true,
    "parser": "babel-eslint",

    "extends": [ "@mutant-ws/eslint-config/targets/react" ],

    "settings": {
        // Use webpack to resolve modules in imports
        "import/resolver": {
            "webpack": {
                "config": "./webpack.config.js",

        // Recommended if you use eslint_d
        "import/cache": {
            "lifetime": 5,

        // List of regex strings that, if matched by a path, will not report
        // the matching module if no exports are found.
        "import/ignore": [ "\\.(sass|scss|less|css)$" ],

    // Custom rules
