#Browsersync - Grunt, SASS & Autoprefixer
|
||
|
|
|
||
|
|
## Installation/Usage:
|
||
|
|
|
||
|
|
To try this example, follow these 4 simple steps.
|
||
|
|
|
||
|
|
**Step 1**: Clone this entire repo
|
||
|
|
```bash
|
||
|
|
$ git clone https://github.com/Browsersync/recipes.git bs-recipes
|
||
|
|
```
|
||
|
|
|
||
|
|
**Step 2**: Move into the directory containing this example
|
||
|
|
```bash
|
||
|
|
$ cd bs-recipes/recipes/grunt.sass.autoprefixer
|
||
|
|
```
|
||
|
|
|
||
|
|
**Step 3**: Install dependencies
|
||
|
|
```bash
|
||
|
|
$ npm install
|
||
|
|
```
|
||
|
|
|
||
|
|
**Step 4**: Run the example
|
||
|
|
```bash
|
||
|
|
$ npm start
|
||
|
|
```
|
||
|
|
|
||
|
|
### Additional Info:
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
This example shows how you can chain potentially slow-running tasks, but still achieve CSS
|
||
|
|
Injection. The trick, as seen below, is to use the `bsReload` task that now comes
|
||
|
|
bundled with `grunt-browser-sync` since `2.1.0`
|
||
|
|
|
||
|
|
Don't forget the `spawn: false` option for the watch task - it's a requirement
|
||
|
|
that allows Browsersync to work correctly
|
||
|
|
|
||
|
|
```js
|
||
|
|
watch: {
|
||
|
|
options: {
|
||
|
|
spawn: false // Important, don't remove this!
|
||
|
|
},
|
||
|
|
files: 'app/**/*.scss',
|
||
|
|
tasks: ['sass', 'autoprefixer', 'bsReload:css']
|
||
|
|
},
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
### Preview of `Gruntfile.js`:
|
||
|
|
```js
|
||
|
|
module.exports = function (grunt) {
|
||
|
|
grunt.initConfig({
|
||
|
|
dirs: {
|
||
|
|
css: "app/css",
|
||
|
|
scss: "app/scss"
|
||
|
|
},
|
||
|
|

|
||

|
||
|
|
spawn: false
|
||
|
|
},

|
|
reload: true
|
||
|
|
}
|
||
|
|
}
|
||
|
|
});
|
||
|
|
|
||
|
|
// load npm tasks
|
||
|
|
grunt.loadNpmTasks('grunt-contrib-sass');
|
||
|
|
grunt.loadNpmTasks('grunt-autoprefixer');
|
||
|
|
grunt.loadNpmTasks('grunt-browser-sync');
|

grunt.loadNpmTasks('grunt-contrib-watch');
|

// define default task
|

grunt.registerTask('default', ['browserSync', 'watch']);
