| 12 | Installation
|
| 13 | ------------------------------------------------------------------------------
|
| 14 |
|
| 15 | ```
|
| 16 | ember install ember-cli-uglify
|
| 17 | ```
|
| 18 |
|
| 19 | Usage
|
| 20 | ------------------------------------------------------------------------------
|
| 21 |
|
| 22 | After installing `ember-cli-uglify` it will automatically hook into the build
|
| 23 | pipeline and minify your JS files in production builds.
|
| 24 |
|
| 25 | If you want to customize how `ember-cli-uglify` is running UglifyJS under the
|
| 26 | hood you have several configuration options available:
|
| 27 |
|
| 28 | ```js
|
| 29 | // ember-cli-build.js
|
| 30 |
|
| 31 | var app = new EmberApp({
|
| 32 | 'ember-cli-uglify': {
|
| 33 | enabled: true,
|
| 34 |
|
| 35 | exclude: ['vendor.js'],
|
| 36 |
|
| 37 | uglify: {
|
| 38 | compress: {
|
| 39 | sequences: 50,
|
| 40 | },
|
| 41 | output: {
|
| 42 | semicolons: true,
|
| 43 | },
|
| 44 | },
|
| 45 | },
|
| 46 | });
|
| 47 | ```
|
| 48 |
|
| 49 |
|
| 50 | ### Options
|
| 51 |
|
| 52 | - `enabled?: boolean`: Enables/Disables minification (defaults to `true` for
|
| 53 | production builds, `false` for development builds)
|
| 54 |
|
| 55 | - `exclude?: string[]`: A list of paths or globs to exclude from minification
|
| 56 |
|
| 57 | - `uglify?: UglifyOptions`: A hash of [options](https://github.com/mishoo/UglifyJS2#minify-options)
|
| 58 | that are passed directly to UglifyJS
|
| 59 |
|
| 60 |
|
| 61 | ### Source Maps
|
| 62 |
|
| 63 | Source maps are disabled by default for production builds in Ember CLI. If you
|
| 64 | want to enable source maps for production builds you can configure that in your
|
| 65 | `ember-cli-build.js` too:
|
| 66 |
|
| 67 | ```js
|
| 68 | // ember-cli-build.js
|
| 69 |
|
| 70 | var app = new EmberApp({
|
| 71 | sourcemaps: {
|
| 72 | enabled: true,
|
| 73 | extensions: ['js'],
|
| 74 | },
|
| 75 | });
|
| 76 | ```
