terser integration to ember-cli to minify your JavaScript.

ember install ember-cli-terser

Note that, ember-cli-terser has no effect under Embroider, as Embroider provides its own minification process based on terser. This means that, apps using Embroider, can safely uninstall ember-cli-terser.

After installing ember-cli-terser it will automatically hook into the build pipeline and minify your JS files in production builds.

If you want to customize how ember-cli-terser is running terser under the hood you have several configuration options available:

// ember-cli-build.js

var app = new EmberApp({
  'ember-cli-terser': {
    enabled: true,

    exclude: ['vendor.js'],

    terser: {
      compress: {
        sequences: 50,
      },
      output: {
        semicolons: true,
      },
    },

    // Tell broccoli-terser-sourcemap to not add sourcemap URLs
    hiddenSourceMap: true,
  },
});

• enabled?: boolean: Enables/Disables minification (defaults to true for production builds, false for development builds)

• exclude?: string[]: A list of paths or globs to exclude from minification

• terser?: TerserOptions: A hash of options that are passed directly to terser

If no terser option is passed, a default configuration will be used.

Options supported by broccoli-terser-sourcemap may be added as top-level fields.

Source maps are disabled by default for production builds in Ember CLI. If you want to enable source maps for production builds you can configure that in your ember-cli-build.js too:

// ember-cli-build.js

var app = new EmberApp({
  sourcemaps: {
    enabled: true,
    extensions: ['js'],
  },
});
