Setting up our Gulpfile 5 WHAT WE NEED GULP TO DO Lint and concatenate our JavaScript Compile our Sass files Minify and rename everything Reload our browser after each change 

Setting up our Gulpfile 5 ➜ project npm install gulp-jshint gulp-sass gulp-concat gulp-uglify gulp-rename gulp-livereload --save-dev 

gulpfile.js // Include gulp var gulp = require('gulp'), ! // Include Our Plugins jshint = require('gulp-jshint’), sass = require(‘gulp-sass'), concat = require(‘gulp-concat’), uglify = require(‘gulp-uglify'), rename = require(‘gulp-rename’); livereload = require(‘gulp-livereload'); Set up Gulp includes 

gulpfile.js // Lint Task gulp.task('lint', function() { return gulp.src('js/*.js') .pipe(jshint()) .pipe(jshint.reporter('default')); }); Set up the Lint task 

gulpfile.js // Compile Our Sass gulp.task('sass', function() { return gulp.src('scss/*.scss') .pipe(sass()) .pipe(gulp.dest('css')); }); Set up the Sass task 

gulpfile.js // Concatenate & Minify JS gulp.task('scripts', function() { return gulp.src('js/*.js') .pipe(concat('main.js')) .pipe(gulp.dest('js')) .pipe(rename('main.min.js')) .pipe(uglify()) .pipe(gulp.dest('js')); }); Concatenate and Minify the JS 

gulpfile.js gulp.task('watch', function() { server.listen(35729, function (err) { if (err) { return console.log(err) }; ! // Watch .scss files gulp.watch('scss/**/*.scss', ['sass']); ! // Watch .js files gulp.watch('js/**/*.js', ['scripts']); ! }); }); Watch the files and reload the browser when changed 

Watch our files for changes 6 ➜ project gulp watch 

Add more plugins. 7
