what's wrong with this code:
var gulp = require('gulp');
var watch = require('gulp-watch');
var connect = require('gulp-connect');
var jshint = require('gulp-jshint');
var stylish = require('jshint-stylish');
//lint
module.exports = gulp.task('lint', function () {
return gulp.src([config.paths.src.scripts,config.paths.exclude.bower])
.pipe(jshint())
.pipe(jshint.reporter(stylish));
});
//watch
module.exports = gulp.task('watch', function () {
watch(config.paths.src.scripts, ['lint'])
.pipe(connect.reload());
watch(config.paths.src.templates, ['templates'])
.pipe(connect.reload());
watch(config.paths.src.index)
.pipe(connect.reload());
});
when ie I edit a js file doing an error
jshint show me nothing.
This works:
watch(config.paths.src.scripts)
.pipe(jshint())
.pipe(jshint.reporter(stylish))
.pipe(connect.reload());
but it's quite the same or not ?
gulp-watch does not support an array of task names like the internal gulp.watch. See documentation at https://www.npmjs.org/package/gulp-watch
You have to provide gulp-watch a function, something like
watch(config.paths.src.scripts, function(events, done) {
gulp.start(['lint'], done);
}
Note: It seems that gulp.start will be deprecated in Gulp 4.x, it will be replaced by a task runner called bach: https://github.com/floatdrop/gulp-watch/issues/92

I'm having trouble with browserSync I can't get reload do trigger after trying several different methods. BrowserSync itself is up and running although when I manually reload nothing happens I have to open a new tab to see any changes. I'm not really understanding gulp 4 and all the sources I have watched seem to be using completely different methods to me. Any help would be greatly appreciated feel free to ask any questions.
var gulp = require('gulp');
var sass = require('gulp-sass');
var concatcss = require('gulp-concat');
var concatjs = require('gulp-concat');
var uglifycss = require('gulp-uglifycss');
var reload = require('browser-sync').reload();
var nunjucks = require('gulp-nunjucks-render');
var browserSync = require('browser-sync').create();
sass.compiler = require('node-sass');
gulp.task('sass', function () {
return gulp.src('./Edit/sass/*.scss')
.pipe(sass().on('error', sass.logError))
.pipe(gulp.dest('./Edit/css'));
});
gulp.task('concatcss', function() {
return gulp.src('./Edit/css/*.css')
.pipe(concatcss('style.css'))
.pipe(gulp.dest('./Edit/css/concated/'));
});
gulp.task('concatjs', function() {
return gulp.src('./Edit/java-script/*.js')
.pipe(concatjs('scripts.js'))
.pipe(gulp.dest('./Upload/js/'));
});
gulp.task('css', function () {
return gulp.src('./Edit/css/concated/*.css')
.pipe(uglifycss({
"maxLineLen": 80,
"uglyComments": true
}))
.pipe(gulp.dest('./upload/css'));
});
gulp.task('browserSync', function() {
browserSync.init({
server: {
baseDir: "./Upload/"
}
});
});
gulp.task('run',gulp.parallel('browserSync', gulp.series('sass','concatcss','concatjs','css')));
gulp.task('watch', function(){
gulp.watch('./Edit/sass/*.scss',gulp.series('sass'));
gulp.watch('./Edit/css/*.css',gulp.series('concatcss'));
gulp.watch('./Edit/java-script/*.js',gulp.series('concatjs')); // maybe put extra task in all gulp series for browser sync
gulp.watch('./Edit/css/concated/*.css', gulp.series('css'));
});
gulp.task('default', gulp.parallel('watch', 'run'));
For anyone else having trouble here is my solution, simply add this .on('change', browserSync.relod) to the end of the desired watch.
gulp.task('watch', function(){
gulp.watch('./Edit/sass/*.scss',gulp.series('sass'));
gulp.watch('./Edit/css/*.css',gulp.series('concatcss'));
gulp.watch('./Edit/java-script/*.js',gulp.series('concatjs')); // maybe put extra task in all gulp series for browser sync
gulp.watch('./Edit/css/concated/*.css', gulp.series('css'));
gulp.watch('./Upload/css/*.css').on('change', browserSync.reload);
gulp.watch('./Upload/js/*.js').on('change', browserSync.reload);
});
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 do not know what could be wrong. When I'm developing most of the time my CPU is using 100%. I have already tried to do this gulpfile.js in several ways and continue with the same error. I read in other posts that there may be some looping I'm doing with no feedback, but I do not know where that error is. Can anyone with more experience help me?
My GULP file is:
'use strict';
var gulp = require('gulp');
var browserSync = require('browser-sync').create();
var util = require('gulp-util');
var compass = require('gulp-compass');
var error = util.colors.bold.red;
function errorHandler(err) {
console.log(error(err.toString()));
this.emit('end');
}
var optionsCompass = {
config_file : 'config.rb',
css : './css',
sass : './scss',
image : './img'
};
gulp.task('scss', function() {
return gulp.src('./scss/**/*.scss')
.pipe(compass(optionsCompass).on('error', errorHandler))
.pipe(gulp.dest('./css'))
.pipe(browserSync.stream());
});
gulp.task('server', function() {
gulp.src('./scss/**/*.scss')
.pipe(compass(optionsCompass).on('error', errorHandler))
.pipe(gulp.dest('./css'));
browserSync.init({
proxy: 'todentro.localhost/'
});
gulp.watch('./scss/**/*.scss', ['scss']);
gulp.watch('./**/*.html', browserSync.reload);
gulp.watch('./**/*.js', browserSync.reload);
});
gulp.task('default', ['server']);
I have the following problem and don't know whats going wrong with my gulpfile. Everything is working fine and my sass files are being compiled and the browser refreshed when changing something.
But if I add a new partial file and import it into my _base.scss, browsersync is only recognizing the change in that partial and is not compiling the whole sass file & reloading the browser. Does anyone know how to solve this problem? I could not figure out a good solution.
Thanks!

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']))
