The Airbnb Javascript Style Guide is the style guide for Javascript and NodeJS used by Airbnb and many other projects.


Install the dependencies and add them to package.json as development dependency:

$ npm install -D eslint
$ npm install -D eslint-config-airbnb-base
$ npm install -D eslint-plugin-import

Add the npm lint script to package.json:

"scripts": {
    "lint": "eslint ."

Create a .eslintrc file in the root of the project:

  "extends": "airbnb-base",
  "env": {
    "node": true
  • The config file above extends from the airbnb-base base configuration file. Rules customizations can be added to this file.
  • Instead of creating the .eslintrc file, these configurations can also be added to the file package.json inside the property eslintConfig.

Create a .eslintignore file in the root of the project:


It is also a good idea to include the path for front-end libraries and vendors in the .eslintignore file.

Finally, run the lint:

$ npm run lint
