Can't serialize tasks with gulp.series() - gulp

Only the first function passed to gulp.series() does fire, the rest just don't. Below is my (simplified) gulpfile.js:
gulp.task('sass', function() {
...
});
gulp.task('js', function() {
...
});
gulp.task('images', function() {
...
});
gulp.task('browserSync', function() {
browserSync.init({
proxy: 'http://127.0.0.1/protection/',
})
})
gulp.task('watch', gulp.series('browserSync', 'js', 'sass', function() {
gulp.watch('../assets/styles/**/*.scss',['sass']);
gulp.watch('../**/**/*.php', browserSync.reload);
gulp.watch('../assets/scripts/*.js', ['js']);
gulp.watch('../*.html', browserSync.reload);
}));
What am I doing wrong?

gulp.task('browserSync', function(done) {
browserSync.init({
proxy: 'http://127.0.0.1/protection/',
})
done();
})
And all other tasks either:
gulp.task('images', function() {
reurn gulp.src()...
});
or
gulp.task('images', function(done) {
...
done();
});
gulp.task('watch', gulp.series('browserSync', 'js', 'sass', function() {
gulp.watch('../assets/styles/**/*.scss', gulp.series('sass'));
gulp.watch('../**/**/*.php', browserSync.reload);
gulp.watch('../assets/scripts/*.js', gulp.series('js'));
gulp.watch('../*.html', browserSync.reload);
}));
gulp.watch('../assets/styles/**/*.scss', 'sass');
might work as well since you are only calling one function/task. I usually just future-proof it a bit with the gulp.series('sass') way of doing it it.
Gulp v4 expects a function (hence your error message) as the second parameter to gulp.watch instead of the gulp v3 array of tasks old parameter.

Gulp + browser-sync doesn't work: 'Cannot GET /'

I am learning the front-end build system currently gulp, i want to use brower-sync and the problem is when it brings up the browser it will not display my html file and it will say "Cannot GET /" error in the browser window. This is my index.js code. Help me 🙏
Thanks :)
import gulp from 'gulp';

return gulp.src('src/assets/scss/styles.scss')
.pipe(rename('css/styles.css'))

Run server function before watch function

creating the server with gulp-connect plugin.
the Code is fine, but when I run gulp, it start monitor the 'watch'
how can I run the server and run the watch function after creating the server.
var gulp = require("gulp"),
scss = require("gulp-scss"),
jsmin = require("gulp-jsmin"),
rename = require("gulp-rename"),
connect = require("gulp-connect");
var path = {
src: {
js: 'dist/js/**/*.js',
css: 'dist/css/**/*.scss',
img: 'dist/img/*.*',
html: '/**/*.html'
},
build: {
js: './js/',
css: './css/',
img: './img/'
}
};
/* connect server */
gulp.task("connect", function () {
connect.server({
root: './',
livereload: true
});
});
/* SASS into css */
gulp.task("styles", function () {
gulp.src(path.src.css)
.pipe(scss())
.pipe(gulp.dest(path.build.css))
.pipe(connect.reload());
});
/* minified JS */
gulp.task("scripts", function () {
gulp.src(path.src.js)
.pipe(jsmin())
.pipe(rename({ suffix: '.min' }))
.pipe(gulp.dest(path.build.js))
.pipe(connect.reload());
});
/* html */
gulp.task("html",function(){
gulp.src(path.src.html)
.pipe(connect.reload());
});
/* watch */
gulp.task('watch', function(){
gulp.watch([path.src.html],["html"]);
gulp.watch([path.src.css],["styles"]);
gulp.watch([path.src.js],["scripts"]);
});
gulp.task("default", ["connect", 'html', 'styles', 'scripts','watch']);
If I skip the watch function then gulp create the server.
Any Help!!!
Change this :
gulp.task("default", ["connect", 'html', 'styles', 'scripts', 'watch']);
to:
gulp.task("default", ['html', 'styles', 'scripts', 'watch']);
and
gulp.task('watch', ['connect'], function(){
gulp.watch([path.src.html],["html"]);
gulp.watch([path.src.css],["styles"]);
gulp.watch([path.src.js],["scripts"]);
});
Now the 'connect' task will run before the 'watch' task starts. I think that is what you want? Also, add return statements to all your tasks. As in
gulp.task("styles", function () {
return gulp.src(path.src.css) ...........

gulp-watch doesn't triggered when create or deleted file

dude ... my gulp doesn't triggered when i create new file or deleted
this is my simple code

Gulp-connect shows an error 'listen EADDRINUSE'

I have a simple gulpfile.js:
var gulp = require('gulp');
var sass = require('gulp-sass');

var notify = require("gulp-notify");
var pngquant = require('imagemin-pngquant');
gulp.task('connect', function() {
connect.server({
root: ['./'],
livereload: true
});
});
gulp.task('sass', function() {
gulp.src(['css/**/*.scss'])
.pipe(sass({
errLogToConsole: false,
onError: function(err) {
return notify().write(err);
}
}))
.pipe(gulp.dest('build'))
.pipe(notify({ message: 'Styles task complete' }))
.pipe(connect.reload());
})
gulp.task('imagemin', function () {
return gulp.src('src/images/*')
.pipe(imagemin({
progressive: true,
svgoPlugins: [{removeViewBox: false}],

}))
.pipe(gulp.dest('build/images/'));

gulp.task('default', function() {

gulp.watch('css/**', function(event) {

gulp.run('connect');

gulp.watch('src/images/*', function(event) {

Whithout gulp-connect everything works fine. I'm sure there is a small syntax error in gulpfile.js but I'm unable to find it. Please help to solve this out.
Here is a final gulpgile.js that works just fine thanx to #Rigotti:
var gulp = require('gulp');
var sass = require('gulp-sass');
var connect = require('gulp-connect');
var imagemin = require('gulp-imagemin');
var notify = require("gulp-notify");
var pngquant = require('imagemin-pngquant');
gulp.task('connect', function() {
connect.server({
root: ['./'],
livereload: true
});
});
gulp.task('sass', function() {
gulp.src(['css/**/*.scss'])
.pipe(sass({
errLogToConsole: false,
onError: function(err) {
return notify().write(err);
}
}))
.pipe(gulp.dest('build'))
.pipe(notify({ message: 'Styles task complete' }))
.pipe(connect.reload());
})
gulp.task('imagemin', function () {
return gulp.src('src/images/*')
.pipe(imagemin({
progressive: true,
svgoPlugins: [{removeViewBox: false}],
use: [pngquant()]
}))
.pipe(gulp.dest('build/images/'));
});
gulp.task('html', function () {
gulp.src('index.html')
.pipe(connect.reload());
});
gulp.task('default', function() {
gulp.run('connect', 'sass', 'imagemin');
gulp.watch('css/**', function(event) {
gulp.run('sass');
})
gulp.watch('*.html', function(event) {
gulp.run('html');
})
gulp.watch('src/images/*', function(event) {
gulp.run('imagemin');
})
})
gulp.task('start', ['connect']);
EADDRINUSE means that the port is already in use.
On the code below you're calling the connect task in default, but connect it's called again when you change your .sass files.
gulp.task('default', function() {
// server started
gulp.run('connect', 'sass', 'imagemin');
gulp.watch('css/**', function(event) {
gulp.run('sass');
gulp.run('connect'); // <-- problem! connect is already running!
});
...
So you're basically trying to listen to the same port you're using, giving you this error.
Remove the gulp.run('connect') inside the watchs and you're good to go.
