eslint-config-drupal-bundle

Eslint with Drupal style

Note: with Drupal 9.x moving to eslint greater than 5.x this setup of having a globally installed plugins and configs will not work under eslint 6+ without major effort setting it up per project. As such if you need the changes provided in eslint 6+ it probably better to web/core yarn install the modules with just have eslint and prettier installed globally or running them from their node_modules path.

see:

• ESLint cannot find global install
• Migrating to ESLint v6.0.0: Plugins and shareable configs are no longer affected by ESLint’s location

ESLint bundled with the original Airbnb Style and prettier/recommended configs. Global installation is supported! No struggle with peer dependencies, easily integrates with your code editors.

See airbnb/javascript and prettier/eslint for more information.

See instructions for WebStorm, VSCode, Sublime Text and Atom

yarn global add eslint-config-drupal-bundle

or

npm -g install eslint-config-drupal-bundle

Create .eslintrc file in your project. Setup your IDE / Editor. And be smart!

ES6, ES7, React, JSX, async/await - all new features supported by default 👍

ESLint inside

You shouldn't add eslint to your dependencies. It's bundled with this package, just specify the path if you need. Here is an example for eslint-loader:

{
  loader: 'eslint-loader',
  options: {
    eslintPath: 'eslint-config-drupal-bundle/node_modules/eslint',
  }
},

WebStorm

File ➤ Settings / Default Settings ➤ Languages and Frameworks ➤ JavaScript ➤ Code Quality Tools ➤ ESLint

Global installation in not necessary for WebStorm, but it is handy for the "Default Settings".

   }

   Relative path for local installation:

   {
     "eslint.nodePath": "node_modules/eslint-config-drupal-bundle/node_modules/eslint",
   }

6. Create .eslintrc.js file inside your working project root:

   process.chdir(__dirname);
   
   module.exports = {
     extends: [
       'drupal-bundle',
     ],
   };

       ],
       "osx": [],
       "windows": ["%AppData%\\npm"]
   },

7. Create .eslintrc file inside your working project:

   {
     "extends": ["drupal-bundle"]
   }

10. You can switch to squiggly underline mark style from Tools. Have fun!

Custom Config

Add your own rules to the .eslintrc file in your project folder. Note: you may want to add root: true to your project.eslintrc to limit eslint looking up parent directories for additional configs.

Credit

All credit to doasync and the original eslint-config-airbnb-bundle of which this is a fork just adding extra config/dependencies of prettier to have function under Drupal 8.6+.
