gulp

The streaming build system

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)
    .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']);

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
