This seems to work: gulp.src([ baseDir + ‘/**’, // Include all ‘!’ + baseDir + ‘/excl1{,/**}’, // Exclude excl1 dir ‘!’ + baseDir + ‘/excl2/**/!(.gitignore)’, // Exclude excl2 dir, except .gitignore ], { dot: true }); Excluding single file from glob match was tricky because there’s no similar examples in minimatch docs. https://github.com/isaacs/minimatch “If the … Read more
UglifyJS does not currently support EcmaScript 6 structures like classes.

Update 2017-06-17 The branch of UglifyJS that is designed to work with ES6 is now published as uglify-es on npm. Update … Read more
For those migrating from gulp v3 to v4 or are using gulp.task() to define tasks in gulp v4 and get this error message: Task never defined, the problem usually lies here: Forward references A forward reference is when you compose tasks, using string references, that haven’t been registered yet.

I managed to get an official word on this from Mads Kristensen in this conversation on Twitter: So in VS2015RC (and RTM too), there is no way to get messages to go to the output window. The task runner only outputs to the error window if the Gulp task returns a failure – but honestly, … Read more
My approach is to create a test instance and use exec and yeoman-assert. Though it feels more like an integration test, I find it helpful to be sure the tasks run properly (my use case being a yeoman-generator). Some (mocha) example: ‘use strict’; var path = require(‘path’); var helpers = require(‘yeoman-generator’).test; var assert = require(‘yeoman-generator’).assert; … Read more
Use this as your start point: var gulp = require(‘gulp’); var gutil = require(‘gulp-util’); var sourcemaps = require(‘gulp-sourcemaps’); var source = require(‘vinyl-source-stream’); var buffer = require(‘vinyl-buffer’); var browserify = require(‘browserify’); var to5ify = require(‘6to5ify’); var uglify = require(‘gulp-uglify’); gulp.task(‘default’, function() { browserify(‘./src/index.js’, { debug: true }) .transform(to5ify) .bundle() .on(‘error’, gutil.log.bind(gutil, ‘Browserify Error’)) .pipe(source(‘bundle.js’)) .pipe(buffer()) .pipe(sourcemaps.init({loadMaps: … Read more
The best way to handle this is to use one of the HTML injectors from the get-go. I’m using gulp-inject to some success so far. Add gulp-inject to your project: npm i –save-dev gulp-inject Assuming that you have a folder layout similar to this: build/ src/ index.html less/ main.less js/ app.js Your HTML should include … Read more

Try installing the ‘del’ package by running the following command in your terminal: npm install del –save-dev If you have already installed ‘del’ package and still getting this … Read more
I just run into the same problem while upgrading to gulp 4. The depending tasks have to be specified as series or in parallel, just the name is not enough anymore. Example gulp.task(‘copy’, [‘sass-min’], function() { Becomes gulp.task(‘copy’, gulp.series(‘sass-min’), function() { gulp.parallel can also be used to execute the tasks in parallel
removing the node_modules folder, clearing npm cached files, and doing a fresh install, resolves this issue. rm -rf node_modules && npm cache clean –force && npm install source: https://github.com/ember-cli/ember-cli/issues/3087#issuecomment-71327402
