I'm running a simple script that turns HAML and LESS into PHP and CSS. I'm also using gulp.watch to check up on all the changes I make.
Problem: gulp-less and gulp-haml process the files correctly. But when gulp.watch sees a change in the file the file ends up empty. gulp.watch is using the exact same task that succesfully created the php file.
var gulp = require('gulp');
var gutil= require('gulp-util');
var path = require('path');
var haml = require('gulp-haml');
var less = require('gulp-less');
// Images
gulp.task('less', function() {
return gulp.src('wp-content/themes/luento/assets/less/*.less')
.pipe(less({paths: [ path.join(__dirname, 'less', 'includes') ]}))
.pipe(gulp.dest('wp-content/themes/luento/assets/css/'));
});
gulp.task('haml-def', function () {
return gulp.src('wp-content/themes/luento/*.haml')
.pipe(haml({ext: '.php'}))
.pipe(gulp.dest('wp-content/themes/luento/'));
});
gulp.task('haml-templates', function () {
return gulp.src('wp-content/themes/luento/templates/*.haml')
.pipe(haml({ext: '.php'}))
.pipe(gulp.dest('wp-content/themes/luento/templates/'));
});
gulp.task('haml-partials', function () {
return gulp.src('wp-content/themes/luento/partials/*.haml')
.pipe(haml({ext: '.php'}))
.pipe(gulp.dest('wp-content/themes/luento/partials/'));
});
// Watch
gulp.task('watch', function() {
// Watch .scss files
gulp.watch('wp-content/themes/luento/templates/*.haml', ['haml-templates']);
gulp.watch('wp-content/themes/luento/partials/*.haml', ['haml-partials']);
gulp.watch('wp-content/themes/luento/*.haml', ['haml-def']);
gulp.watch('wp-content/themes/luento/assets/less/*.less', ['less'])
});
gulp.task('default', ['less', 'haml-def', 'haml-templates','haml-partials','watch']);

I have problem. Yestrday I had to update the Node.js kernel and now that I change something in the LESS file, there will be no css update. Gulpfile is the same as before the update. Could someone advise me what's wrong with my gulpfile script?
The HTML file update is OK.

Thanks for your advice :-)
I try this path, but problem remains.
Last version node.js was Node.js 7.2.1 (Node.js), now Node.js 9.8.0.
I attach an image to the console after changing 1 line in the LESS file.
Here I see that the set of commands does not call correctly. Or they are called repeatedly. Do not you see a mistake here, please?
Thanks for your advice
I'm having a strange problem. I'm using gulp to compile a react app and am having it copy index.html to the appropriate web directory. When I first run gulp, all runs as expected, but when the file changes and the watch task is run, gulp copies an empty version of the file to the web directory. Does anyone know why this might be happening? Here is my gulpfile.js:
var gulp = require('gulp');
var browserify = require('browserify');
var babelify = require('babelify');
var source = require('vinyl-source-stream');
var livereload = require('gulp-livereload');
gulp.task('livereload', function() {
console.log('reloading');
livereload();
});
gulp.task('copyindextodist', function() {
gulp.src('app/index.html')
.pipe(gulp.dest('dist'));
});
gulp.task('compilejs', function() {
browserify({
entries: 'app/index.js',
extensions: ['.js'],
debug: true
})
.transform('babelify', {presets: ['es2015', 'react']})
.bundle()
.pipe(source('app.js'))
.pipe(gulp.dest('dist'));
});
gulp.task('publishapp', function() {
gulp.src('dist/*.*')
.pipe(gulp.dest('../public'));
});
gulp.task('copypaste', function() {
gulp.src('app/index.html')
.pipe(gulp.dest('../public'));
});
gulp.task('watch', function() {
livereload.listen();
gulp.watch('app/index.html', ['copyindextodist']);
gulp.watch('dist/index.html', ['publishapp']);
gulp.watch('app/index.js', ['compilejs']);
gulp.watch('dist/app.js', ['publishapp']);
});
gulp.task('default', ['copyindextodist', 'compilejs', 'publishapp', 'watch']);
I had the same problem until I defined the dependencies correctly. You can define which tasks should be completed, before the current task starts:
gulp.task('compress', ['copy'], function() {
//.... your job
});
This means that the compress task will wait for the copy task to be finished. If you don't do that, you might end up with empty/truncated files and other strange results.
Just take care that your copy tasks return a stream object.
gulp.task('copy', function() {
// "return" is the important part ;-)
return gulp.src(['filepath/**/*'])
.pipe(gulp.dest('lib/newpath'))
});
If you have multiple copy commands running in your task this is tricky, but there is an extension for this:
var gulp = require('gulp');
var merge = require('merge-stream');
gulp.task('copy', function() {
var allStreams = [
gulp.src(['node_modules/bootstrap/dist/**/*'])
.pipe(gulp.dest('lib/bootstrap')),
gulp.src(['node_modules/jquery/dist/**/*'])
.pipe(gulp.dest('lib/jquery')),
];
return merge.apply(this, allStreams);
});
gulp.task('nextTask', ['copy'], function() {
// this task formerly produced empty files, but now
// has a valid dependency on the copy stream and
// thus has all files available when processed.
});
I have been playing with gulp and babel for the past few days. I am getting a solid grasp of setting up babel with gulp through tutorials. I've noticed that the newer the tutorial the more changes that develop.
Here is one way I was able to set up es6 to es5 with a transpiler.
var gulp = require('gulp');
var babel = require('gulp-babel');
gulp.task('es6to5', function () {
return gulp.src('js/src/app.js')
.pipe(babel())
.pipe(gulp.dest('dist'));
});
However, I do not want to rerun gulp each time, and I want the dist/ folder to update on each save.
I added browser-sync and delete.
var gulp = require('gulp');
var babel = require('gulp-babel');
var browserSync = require('browser-sync');
var del = require('del');
gulp.task('clean:dist', function() {
return del([
'dist/app.js'
]);
});
gulp.task('es6to5', function () {
return gulp.src('js/src/app.js')
.pipe(babel())
.pipe(gulp.dest('dist'));
});
gulp.task("browserSync", function() {
browserSync({
server: {
baseDir: './dist'
}
});
});
gulp.task("copyIndex", ['clean:dist'], function() {
gulp.src("src/index.html")
.pipe(gulp.dest('./dist'))
.pipe(browserSync.reload({stream: true}));
});
gulp.task('watchFiles', function() {
gulp.watch('src/index.html', ['copyIndex']);
gulp.watch('src/**/*.js', ['babelIt']);
});
gulp.task('default', ['clean:dist', 'es6to5','browserSync','watchFiles']);
I set up a default that will clean out the dist folder then run es6to5. Afterwards I want it to sync and update. I called watchFiles last.
However, I am no longer getting updated js files. The files in the dist folder Are not compiling to es5 and everything is going to a 404.
The task
copyIndex seems to be the problem but I am not sure how to fix it or if it is the only problem. Any direction helps.
You have a typo.
It should be gulp.watch('src/**/*.js', ['es6to5']);, not gulp.watch('src/**/*.js', ['babelIt']);
Anyway i suggest to use gulp-watch instead of the built-in watch function. It has several advantages, mainly it recompile on new file creation.
I am trying to create a basic gulp build process template that starts with an app folder containing html, sass, javascript, and image files and builds those files into a public folder. I am using gulp to watch the app folder for changes and then automatically refreshing the build process to the public folder.
I using browser-sync to serve the public folder and watch for changes but it doesn't seem to automatically reload when a change to the public folder is made. If I manually refresh the browser the changes are reflected.
Thanks for the help, see below for my gulp file:
//BASIC GULP FILE SETUP
//-------------------------------------------------------------
//Include Gulp
var gulp = require('gulp');
//General Plugins
var browserSync = require('browser-sync').create();
var reload = browserSync.reload;
var del = require('del');
var watch = require('gulp-watch');
var runSequence = require('run-sequence');
//CSS Plugins
var sass = require('gulp-sass');
var autoprefixer = require('gulp-autoprefixer');
var csso = require('gulp-csso');
//JS Plugins
var concat = require('gulp-concat');
var uglify = require('gulp-uglify');
//HTML Plugins
var minifyHTML = require('gulp-minify-html');
//IMG Plugins
//-------------------------------------------------------------
//TASKS
//-------------------------------------------------------------
//Clean Public Folder
gulp.task('clean', function() {
del(['public/**/*']);
});
//CSS Tasks
gulp.task('sass', function () {
return gulp.src('app/sass/**/*.scss')
.pipe(sass())
.pipe(autoprefixer())
.pipe(csso())
.pipe(gulp.dest('public/css'));
});
//HTML Tasks
gulp.task('html', function () {
return gulp.src(['./app/**/*.html'], {
base: 'app'
})
.pipe(minifyHTML())
.pipe(gulp.dest('public'))
;
});
//Image Tasks
gulp.task('image', function () {
return gulp.src('app/img/**/*.{png,jpg,jpeg,gif,svg}')
.pipe(gulp.dest('public/images'));
});
//JS Tasks
gulp.task('js', function () {
return gulp.src('app/js/**/*.js')
.pipe(concat('main.js'))
.pipe(uglify())
.pipe(gulp.dest('public/js'));
});
// Watch files for changes
gulp.task('watch', function() {
// Watch HTML files
gulp.watch('./app/*.html', ['html'], browserSync.reload);
// Watch Sass files
gulp.watch('./app/sass/**/*.scss', ['sass'], browserSync.reload);
// Watch JS files
gulp.watch('./app/js/**/*', ['js'], browserSync.reload);
// Watch image files
gulp.watch('./app/img/*', ['image'], browserSync.reload);
});
gulp.task('browser-sync', ['watch'], function() {
browserSync.init({
server: {
baseDir: "./public"
}
});
});
gulp.task('defualt');
gulp.task('build', [], function(callback) {
runSequence('clean',
'sass',
'html',
'js',
'image');
});
I did a little more poking around the forums and the browser-sync documentation. In my serve task I needed to add a watch function to the Public directory that would manually call the reload every time a change was detected. So my 'browser-sync' task, now renamed 'serve', needs to look like this:
//Browser Sync Server
gulp.task('serve', ['watch'], function() {
browserSync.init({
server: {
baseDir: "./public"
}
});
gulp.watch("./public/**/*").on("change", browserSync.reload);
});
I am sure there is a way to do this with browser-sync's streams as well, but this manual reload method found in the docs has done the trick.
Try passing in a files object in the init function so it knows what to look for. No need for a different watch task, Browsersync does all that for you.
gulp.task('browser-sync', ['watch'], function() {
browserSync.init({
server: {
baseDir: "./public"
},
files: [
'**/*.css',
'**/*.js',
'**/*.html'
// etc...
]
});
});
What is the proper way to use gulp-watch plugin?
...
var watch = require('gulp-watch');
function styles() {
return gulp.src('app/styles/*.less')
.pipe(watch('app/styles/*.less'))
.pipe(concat('main.css'))
.pipe(less())
.pipe(gulp.dest('build'));
}
gulp.task('styles', styles);
I don't see any results when run gulp styles.
In your shell (such as Apple's or Linux's Terminal or iTerm) navigate to the folder that your gulpfile.js. For example, if you're using it with a WordPress Theme your gulpfile.js should be in your Theme's root. So navigate there using cd /path/to/your/wordpress/theme.
Then type gulp watch and hit enter.
If your gulpfile.js is configured properly (see example below) than you will see output like this:
[15:45:50] Using gulpfile /path/to/gulpfile.js
[15:45:50] Starting 'watch'...
[15:45:50] Finished 'watch' after 11 ms
Every time you save your file you'll see new output here instantly.
Here is an example of a functional gulpfile.js:
var gulp = require('gulp'),
watch = require('gulp-watch'),
watchLess = require('gulp-watch-less'),
pug = require('gulp-pug'),
less = require('gulp-less'),
minifyCSS = require('gulp-csso'),
concat = require('gulp-concat'),
sourcemaps = require('gulp-sourcemaps');
gulp.task('watch', function () {
gulp.watch('source/less/*.less', ['css']);
});
gulp.task('html', function(){
return gulp.src('source/html/*.pug')
.pipe(pug())
.pipe(gulp.dest('build/html'))
});
gulp.task('css', function(){
return gulp.src('source/less/*.less')
.pipe(less())
.pipe(minifyCSS())
.pipe(gulp.dest('build/css'))
});
gulp.task('js', function(){
return gulp.src('source/js/*.js')
.pipe(sourcemaps.init())
.pipe(concat('app.min.js'))
.pipe(sourcemaps.write())
.pipe(gulp.dest('build/js'))
});
gulp.task('default', [ 'html', 'js', 'css', 'watch']);
Note: Anywhere you see source/whatever/ this is a path you'll either need to create or update to reflect the path you're using for the respective file.
gulp.task('less', function() {
gulp.src('app/styles/*.less')
.pipe(less())
.pipe(gulp.dest('build'));
});
gulp.task('watch', function() {
gulp.watch(['app/styles/*.less'], ['less'])
});
Name your task like I have my 'scripts' task named so you can add it to the series. You can add an array of tasks to the series and they will be started in the order they are listed. For those coming from prior versions note the return on the gulp.src.
This is working code I hope it helps the lurkers.
Then (for version 4+) you need to do something like this:
var concat = require('gulp-concat'); // we can use ES6 const or let her just the same
var uglify = require('gulp-uglify'); // and here as well
gulp.task('scripts', function(done) {
return gulp.src('./src/js/*.js')
.pipe(concat('all.js'))
.pipe(uglify())
.pipe(gulp.dest('./dist/js/'));
});
gulp.task('watch', function() {
gulp.watch('./src/js/*.js',gulp.series(['scripts']))
});
** Note the line gulp.watch('./src/js/*.js',gulp.series(['scripts'],['task2'],['etc']))
