The streaming build system

[![NPM version][npm-image]][npm-url] [![Downloads][downloads-image]][npm-url] [![Build Status][ci-image]][ci-url] [![Coveralls Status][coveralls-image]][coveralls-url] ## 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 3000 curated plugins for streaming file transformations. - **Simple** - By providing only a minimal API surface, gulp is easy to learn and simple to use. ## Installation Follow our [Quick Start guide][quick-start]. ## Roadmap Find out about all our work-in-progress and outstanding issues at https://github.com/orgs/gulpjs/projects. ## Documentation Check out the [Getting Started guide][getting-started-guide] and [API docs][api-docs] on our website! __Excuse our dust! All other docs will be behind until we get everything updated. Please open an issue if something isn't working.__ ## Sample `gulpfile.js` This file will give you a taste of what gulp does. ```js var gulp = require('gulp'); var less = require('gulp-less'); var babel = require('gulp-babel'); var concat = require('gulp-concat'); var uglify = require('gulp-uglify'); var rename = require('gulp-rename'); var cleanCSS = require('gulp-clean-css'); var del = require('del'); var paths = { styles: { src: 'src/styles/**/*.less', dest: 'assets/styles/' }, scripts: { src: 'src/scripts/**/*.js', dest: 'assets/scripts/' } }; /* Not all tasks need to use streams, a gulpfile is just another node program * and you can use all packages available on npm, but it must return either a * Promise, a Stream or take a callback and call it */ function clean() { // You can use multiple globbing patterns as you would with `gulp.src`, // for example if you are using del 2.0 or above, return its promise return del([ 'assets' ]); } /* * Define our tasks using plain functions */ function styles() { return gulp.src(paths.styles.src) .pipe(less()) .pipe(cleanCSS()) // pass in options to the stream .pipe(rename({ basename: 'main', suffix: '.min' })) .pipe(gulp.dest(paths.styles.dest)); } function scripts() { return gulp.src(paths.scripts.src, { sourcemaps: true }) .pipe(babel()) .pipe(uglify()) .pipe(concat('main.min.js')) .pipe(gulp.dest(paths.scripts.dest)); } function watch() { gulp.watch(paths.scripts.src, scripts); gulp.watch(paths.styles.src, styles); } /* * Specify if tasks run in series or parallel using `gulp.series` and `gulp.parallel` */ var build = gulp.series(clean, gulp.parallel(styles, scripts)); /* * You can use CommonJS `exports` module notation to declare tasks */ exports.clean = clean; exports.styles = styles; exports.scripts = scripts; exports.watch = watch; exports.build = build; /* * Define default task that can be called by just running `gulp` from cli */ exports.default = build; ``` ## Use latest JavaScript version in your gulpfile Gulp provides a wrapper that will be loaded in your ESM code, so you can name your gulpfile as `gulpfile.mjs` or with `"type": "module"` specified in your `package.json` file. And here's the same sample from above written in **ESNext**. ```js import { src, dest, watch } from 'gulp'; import less from 'gulp-less'; import babel from 'gulp-babel'; import concat from 'gulp-concat'; import uglify from 'gulp-uglify'; import rename from 'gulp-rename'; import cleanCSS from 'gulp-clean-css'; import del from 'del'; const paths = { styles: { src: 'src/styles/**/*.less', dest: 'assets/styles/' }, scripts: { src: 'src/scripts/**/*.js', dest: 'assets/scripts/' } }; /* * For small tasks you can export arrow functions */ export const clean = () => del([ 'assets' ]); /* * You can also declare named functions and export them as tasks */ export function styles() { return src(paths.styles.src) .pipe(less()) .pipe(cleanCSS()) // pass in options to the stream .pipe(rename({ basename: 'main', suffix: '.min' })) .pipe(dest(paths.styles.dest)); } export function scripts() { return src(paths.scripts.src, { sourcemaps: true }) .pipe(babel()) .pipe(uglify()) .pipe(concat('main.min.js')) .pipe(dest(paths.scripts.dest)); } /* * You could even use `export as` to rename exported tasks */ function watchFiles() { watch(paths.scripts.src, scripts); watch(paths.styles.src, styles); } export { watchFiles as watch }; const build = gulp.series(clean, gulp.parallel(styles, scripts)); /* * Export a default task */ export default build; ``` ## Incremental Builds You can filter out unchanged files between runs of a task using the `gulp.src` function's `since` option and `gulp.lastRun`: ```js const paths = { ... images: { src: 'src/images/**/*.{jpg,jpeg,png}', dest: 'build/img/' } } function images() { return gulp.src(paths.images.src, {since: gulp.lastRun(images)}) .pipe(imagemin()) .pipe(gulp.dest(paths.images.dest)); } function watch() { gulp.watch(paths.images.src, images); } ``` Task run times are saved in memory and are lost when gulp exits. It will only save time during the `watch` task when running the `images` task for a second time. ## Want to contribute?
