@babel/eslint-plugin

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 10.13 or greater

Install

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

Load the plugin in your .eslintrc.json 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": "error",
    "@babel/no-invalid-this": "error",
    "@babel/no-undef": "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-undef: handles class accessor properties (class A { accessor x = 2 })
@babel/no-unused-expressions: handles do expressions
@babel/object-curly-spacing: handles export * as x from "mod"; (????)
@babel/semi: Handles class properties (????)

TypeScript

While @babel/eslint-parser can parse TypeScript, we don't currently support linting TypeScript using the rules in @babel/eslint-plugin. This is because the TypeScript community has centered around @typescript-eslint and we want to avoid duplicate work. Additionally, since @typescript-eslint uses TypeScript under the hood, its rules can be made type-aware, which is something Babel doesn't have the ability to do.
