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
npm install eslint-plugin-babel --save-dev
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/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
}
}
Rules
Each rule corresponds to a core eslint rule, and has the same options.
????: means it's autofixable with --fix.
