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 reimplements 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/object-curly-spacing": 1,
    "babel/object-shorthand": 1,
    "babel/arrow-parens": 1,
    "babel/no-await-in-loop": 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/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
• bael/no-await-in-loop: guard against awaiting async functions inside of a loop
