+#Browsersync - Gulp, SASS + Slow running tasks
+

+
+**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/gulp.task.sequence
+```
+
+**Step 3**: Install dependencies

+$ npm install
+```
+
+**Step 4**: Run the example
+```bash
+$ npm start
+```
+
+### Additional Info:
+
+
+
+This example highlights a common problem where you don't want to reload
+ the browser until a 2 or more slow-running tasks have completed. The solution
+ is to create the intermediate task that ensures `browserSync.reload` is not 
+ called until both slow tasks are complete.
+
+
+### Preview of `gulpfile.js`:
+```js
+var gulp        = require('gulp');
+var browserSync = require('browser-sync');
+var sass        = require('gulp-sass');
+var reload      = browserSync.reload;
+var through     = require("through2");
+
+/**
+ * A slow task
+ */
+gulp.task('slow1', function () {
+    return gulp.src('./app/*.html')
+        .pipe(slowStream());
+});
+
+/**
+ * Another Slow task
+ */
+gulp.task('slow2', function () {
+    return gulp.src('./app/*.html')
+        .pipe(slowStream());
+});
+
+/**
+ * Separate task for the reaction to a file change
+ */
+gulp.task('html-watch', ['slow1', 'slow2'], reload);
+
+/**
+ * Sass task for live injecting into all browsers
+ */
+gulp.task('sass', function () {
+    return gulp.src('./app/scss/*.scss')
+        .pipe(sass())
+        .pipe(gulp.dest('./app/css'))
+        .pipe(reload({stream: true}));
+});
+
+/**
+ * Serve and watch the html files for changes
+ */
+gulp.task('default', function () {
+
+    browserSync({server: './app'});
+
+    gulp.watch('./app/scss/*.scss', ['sass']);
+    gulp.watch('./app/*.html',      ['html-watch']);
+});
+
+/**
+ * Simulate a slow task
+ */
+function slowStream () {
+    return through.obj(function (file, enc, cb) {
+        this.push(file);
+        setTimeout(cb, 2000);
+    });
+}
+```
