@babel/eslint-plugin

This project is still experimental and will be released with Babel v8. You can track our progress here! Please use eslint-plugin-babel in the meantime.

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

Requires Node 10.9 or greater

Install

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

Load the plugin in your .eslintrc.json file:

{
  "plugins": ["@babel/eslint-plugin"]
}

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

{
  "rules": {
    "babel/new-cap": "error",
    "babel/no-invalid-this": "error",
    "babel/no-unused-expressions": "error",
    "babel/object-curly-spacing": "error",
    "babel/semi": "error",
  }
}

Rules

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

🛠: means it's autofixable with --fix.

• babel/new-cap: handles decorators (@Decorator)
• babel/no-invalid-this: handles class fields and private class methods (class A { a = this.b; })
• babel/no-unused-expressions: handles do expressions
• babel/object-curly-spacing: handles export * as x from "mod"; (🛠)
• babel/semi: Handles class properties (🛠)
