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.

Install

npm install eslint-plugin-babel -D

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/generator-star-spacing": 1,
    "babel/new-cap": 1,
    "babel/array-bracket-spacing": 1,
    "babel/object-curly-spacing": 1,
    "babel/object-shorthand": 1,
    "babel/arrow-parens": 1,
    "babel/no-await-in-loop": 1,
    "babel/flow-object-type": 1
  }
}

Rules

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

babel/generator-star-spacing: Handles async/await functions correctly
babel/new-cap: Ignores capitalized decorators (@Decorator)
babel/array-bracket-spacing: Handles destructuring arrays with flow type in function parameters
babel/object-curly-spacing: doesn't complain about export x from "mod"; or export * as x from "mod";
babel/object-shorthand: doesn't fail when using object spread (...obj)
babel/arrow-parens: Handles async functions correctly

The following rules are not in eslint, but are relevant only to syntax that is not specified by the current JavaScript standard or supported by eslint.

babel/no-await-in-loop: guard against awaiting async functions inside of a loop
babel/flow-object-type: Require a particular separator between properties in Flow object types.
- Use the option semicolon to require semicolons (e.g. type Foo = { bar: number; baz: string }).
- Use the option comma to require commas (e.g. type Foo = { bar: number, baz: string }).
