#Browsersync - Gulp & Ruby SASS

Installation/Usage:

To try this example, follow these 4 simple steps.

Step 1: Clone this entire repo

$ git clone https://github.com/Browsersync/recipes.git bs-recipes

Step 2: Move into the directory containing this example

$ cd bs-recipes/recipes/gulp.ruby.sass

Step 3: Install dependencies

Step 4: Run the example

$ npm start

Additional Info:

This example highlights both the stream support for injecting CSS, aswell as the support for calling reload directly following html changes.

We also need to filter out any source maps created by ruby-sass.

Preview of gulpfile.js:

var gulp         = require('gulp');
var browserSync  = require('browser-sync');
var filter       = require('gulp-filter');
var sass         = require('gulp-ruby-sass');
var sourcemaps   = require('gulp-sourcemaps');
var reload       = browserSync.reload;

var src = {
    scss: 'app/scss/*.scss',
    css:  'app/css',
    html: 'app/*.html'
};

/**
 * Kick off the sass stream with source maps + error handling
 */
function sassStream () {
    return sass('app/scss', {sourcemap: true})
        .on('error', function (err) {
            console.error('Error!', err.message);
        })
        .pipe(sourcemaps.write('./', {
            includeContent: false,
            sourceRoot: '/app/scss'
        }));
}

/**
 * Start the Browsersync Static Server + Watch files
 */
gulp.task('serve', ['sass'], function() {

    browserSync({
        server: "./app"
    });

    gulp.watch(src.scss, ['sass']);
    gulp.watch(src.html).on('change', reload);
});

/**
 * Compile sass, filter the results, inject CSS into all browsers
 */
gulp.task('sass', function() {
    return sassStream()
        .pipe(gulp.dest(src.css))
        .pipe(filter("**/*.css"))
        .pipe(reload({stream: true}));
});

/**
 * Default task
 */
gulp.task('default', ['serve']);
