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

$3

``sh
npm install eslint-plugin-babel --save-dev
`

Load the plugin in your .eslintrc file:

`json
{
"plugins": [
"babel"
]
}
`

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

`json
{
"rules": {
"babel/new-cap": 1,
"babel/camelcase": 1,
"babel/no-invalid-this": 1,
"babel/object-curly-spacing": 1,
"babel/quotes": 1,
"babel/semi": 1,
"babel/no-unused-expressions": 1,
"babel/valid-typeof": 1
}
}
`

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').
