    eslint-plugin-babel

    An eslint plugin companion to babel-eslint. babel-eslint does a great job at adapting eslint for use with Babel, but it can't change the built in rules to support experimental features. eslint-plugin-babel re-implements problematic rules so they do not give false positives or negatives.

    Requires Node 4 or greater

    Install

    npm install eslint-plugin-babel --save-dev

    Load the plugin in your .eslintrc file:

    {
      "plugins": [
        "babel"
      ]
    }

    Finally enable all the rules you would like to use (remember to disable the original ones as well!).

    {
      "rules": {
        "babel/new-cap": 1,
        "babel/camelcase": 1,
        "babel/no-invalid-this": 1,
        "babel/object-curly-spacing": 1,
        "babel/quotes": 1,
        "babel/semi": 1,
        "babel/no-unused-expressions": 1,
        "babel/valid-typeof": 1
      }
    }

    Rules

    Each rule corresponds to a core eslint rule, and has the same options.

    🛠: means it's autofixable with --fix.

    • babel/new-cap: Ignores capitalized decorators (@Decorator)
    • babel/camelcase: doesn't complain about optional chaining (var foo = bar?.a_b;)
    • babel/no-invalid-this: doesn't fail when inside class properties (class A { a = this.b; })
    • babel/object-curly-spacing: doesn't complain about export x from "mod"; or export * as x from "mod"; (🛠)
    • babel/quotes: doesn't complain about JSX fragment shorthand syntax (<>foo</>;)
    • babel/semi: doesn't fail when using for await (let something of {}). Includes class properties (🛠)
    • babel/no-unused-expressions: doesn't fail when using do expressions or optional chaining (a?.b()).
    • babel/valid-typeof: doesn't complain when used with BigInt (typeof BigInt(9007199254740991) === 'bigint').
