The streaming build system
For a Getting started guide, API docs, recipes, making a plugin, etc. see the documentation page!
This file is just a quick sample to 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 all packages available on npm
gulp.task('clean', function(cb) {
// You can use multiple globbing patterns as you would with `gulp.src`
del(['build'], cb);
});
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']);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
