eslint-plugin-babel
NOTE: eslint-plugin-babel is now @babel/eslint-plugin
and has moved into the Babel monorepo.
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/semi": 1,

}
}
Rules
Each rule corresponds to a core eslint
rule, and has the same options.
🛠: means it's autofixable with --fix
.
