A sample gulp testing app

Why this Gulp Starter Kit

This is an simple example to automate our project scripts merged into one js file with compress. This will helps to boost the performance to load js only one time which always produce render blocking on any web site, I mean the more you add scripts your website will be more slow. Though theres lot of technique to over come js render blocking issue which is not the topic of this project

What is gulp?

• Automation - gulp is a toolkit that helps you automate painful or time-consuming tasks in your development workflow.
• Platform-agnostic - Integrations are built into all major IDEs and people are using gulp with PHP, .NET, Node.js, Java, and other platforms.
• Strong Ecosystem - Use npm modules to do anything you want + over 2000 curated plugins for streaming file transformations
• Simple - By providing only a minimal API surface, gulp is easy to learn and simple to use

Sample gulpfile.js

var gulp = require('gulp');
var coffee = require('gulp-coffee');
var concat = require('gulp-concat');
var uglify = require('gulp-uglify');
var imagemin = require('gulp-imagemin');
var sourcemaps = require('gulp-sourcemaps');
var del = require('del');

var paths = {
  scripts: ['client/js/**/*.coffee', '!client/external/**/*.coffee'],
  images: 'client/img/**/*'
};

// Not all tasks need to use streams
// A gulpfile is just another node program and you can use any package available on npm
gulp.task('clean', function() {
  // You can use multiple globbing patterns as you would with `gulp.src`
  return del(['build']);
});

gulp.task('scripts', ['clean'], function() {
  // Minify and copy all JavaScript (except vendor scripts)
  // with sourcemaps all the way down
  return gulp.src(paths.scripts)
    .pipe(sourcemaps.init())
      .pipe(coffee())
      .pipe(uglify())
      .pipe(concat('all.min.js'))
    .pipe(sourcemaps.write())
    .pipe(gulp.dest('build/js'));
});

// Copy all static images
gulp.task('images', ['clean'], function() {
  return gulp.src(paths.images)
    // Pass in options to the task
    .pipe(imagemin({optimizationLevel: 5}))
    .pipe(gulp.dest('build/img'));
});

// Rerun the task when a file changes
gulp.task('watch', function() {
  gulp.watch(paths.scripts, ['scripts']);
  gulp.watch(paths.images, ['images']);
});

// The default task (called when you run `gulp` from cli)
gulp.task('default', ['watch', 'scripts', 'images']);
