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

Load the plugin in your .eslintrc file:

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

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').
