⚒ Drupal JS Build

Command line to build JS files the way Drupal core does.

Just create your JS files as [name].es6.js. When this tool is executed, those files will be compiled by Babel to [name].js.

The script files were directly taken from Drupal core codebase and updated to support custom build configurations using the .drupalbuild.js file. The default configuration will match Drupal's default behaviour/convention.

Overview

Install it:

npm i drupal-js-build --save-dev

or globally:

npm i -g drupal-js-build

To build the files:

npx drupal-js-build

To watch the files:

npx drupal-js-build watch

Bonus

This tool can also compile SASS files using node-sass.

The recommended folder structure is ./css/sass/[file].scss. The files will be compiled to parent folder as ./css/[file].css

To compile js and scss files:

npx drupal-js-build --css

or

npx drupal-js-build watch --css

To compile scss files only:

npx drupal-js-build --only-css

or

npx drupal-js-build watch --only-css

Configuration.

You may configure how the script runs by creating a local .drupalbuild.js file in the working directory running the script.

An example configuration is available below:

module.exports = {
 ignoreList: [
   // Don't include the local .ignore-me folder.
   './.ignore-me/**'
 ],
 watchSettings: {
     // Additional settings to pass along to chokidar.watch
     usePolling: true, // Use polling in non-standard environments.
 },
 sassSettings: {
   // Additional settings to pass along to the node-sass.render.
   sourceMap: false, // Disable CSS sourcemaps.
 },
 jsHeader: `Custom JS header comment`, // May be set to null to remove the header.
 cssHeader: `/**\n * Custom CSS header comment.\n **/\n`, // May be set to null to remove the header.
 files: {
   // Note: All matched files must end in '.es6.js'
   jsSrc: './**/*.es6.js',
   jsDestination: './', // Relative to the currently processed es6.js file.
   // Note: All matched files must end in '.scss'
   scssSrc: './css/**/[!_]*.scss', 
   scssDestination: '../',  // Relative to the currently processed scss file.
 },
};
