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

This file will give you a taste of what gulp does.

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)

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

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

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

Incremental Builds

We recommend these plugins:

  • gulp-changed - only pass through changed files
  • gulp-cached - in-memory file cache, not for operation on sets of files
  • gulp-remember - pairs nicely with gulp-cached
  • gulp-newer - pass through newer source files only, supports many:1 source:dest
