simple setup with gulp - browserify - browsersync: required is not defined - javascript

I have this gulp code that works fine with browser-sync and the gulp sass compiler, I've tried to insert a browserify task but seems doesn't work, it works if I type on the command line:
browserify src/js/main.js -o src/js/bundle/bundle.js
this is my project structure:
|-project
|--/src
|---/css
|----style.css
|---/js
|----main.js
|----/bundle
|-----bundle.js
|---/scss
|----_bootstrap.scss
|----style.scss
|---/assets
|----/img
|---index.html
|--gulpfile.js
|--package.json
and this is my gulp file:
const gulp = require('gulp');
const browserSync = require('browser-sync').create();
const sass = require('gulp-sass');
const browserify = require('browserify');
gulp.task('sass', () => {
return gulp.src("./src/scss/*.scss")
.pipe(sass().on('error', sass.logError))
.pipe(gulp.dest("./src/css"))
.pipe(browserSync.stream());
});
gulp.task('js',()=>{
return gulp.src('./src/js/main.js')
.pipe(browserify())
.pipe(gulp.dest('./src/js/bundle'))
});
gulp.task('serve', ()=> {
browserSync.init({
injectChanges: true,
server: "./src"
});
gulp.watch("./src/scss/*.scss", gulp.series('sass'));
gulp.watch("./src/js/*.js", gulp.series('js'));
gulp.watch("./src/*.html").on('change', browserSync.reload);
});
gulp.task('default', gulp.series('serve','sass','js'));
I have recently added the 'js' task but when I type gulp in the command line everything works fine except for the browserify task.
as a test the main.js file looks like this:
const jquery = require('../../node_modules/jquery')
console.log(jquery)
and I still get the error 'required is not defined'. there is something i missed out. Many thanks

ok, finally works (seems...) it was not a problem with browserify but with the new version of gulp, instead of:
gulp.task('default', gulp.series('serve','sass','js'));
I have had to do:
gulp.task('default', gulp.parallel('serve','sass','js'));
before the sass and js task didn't start, now with parallel function seems works

How do I reload my JS files using browse-sync with GULP JS?

I created a project with gulp js, installed bootstrap, browse-sync and sass.
My gulpfile.js file looks like this:
var gulp = require('gulp');
var browserSync = require('browser-sync').create();
const sass = require('gulp-sass')(require('sass'));
gulp.task('sass', () => {
return gulp.src("./sass/*.scss")
.pipe(sass())
.pipe(gulp.dest("dist/"))
.pipe(browserSync.stream());
});
gulp.task('start', gulp.series('sass', function() {
browserSync.init({
server: "./"
});
gulp.watch("sass/*.scss", gulp.series('sass'));
gulp.watch("./*.html").on('change', browserSync.reload);
}));
gulp.task('default', gulp.series('start'));
When I use the Ctrl + S command in HTML and SCSS files, my project is saved and browser is reloaded; but I want to do this also for my JS files. Can you help me?
Very similar to the way you are dealing with your css, but you can use other plugins like terser to compress your javascript. Here is my js function which concatenates and minifies my javascript before reloading via browsersync
const concat = require('gulp-concat');
const terser = require('gulp-terser');
function js() {
return src(['./js/*.js'])
.pipe(concat('scripts.min.js'))
.pipe(terser())
.pipe(dest('js'))
.pipe(browsersync.stream());
}

Gulp and Three js not allowing import or require

I want to use Gulp in my future projects, but what it is more important to me is to add Three.js modular functionality, to the project, with normal plugins example uglify i dont have any problems, but when i run my gulp file in my js code theres always a error THREE is not defined, or if i type
var THREE = require('three');
it says require is not defined, the same if i add a import,
import * as THREE from "three";
import is not defined
hope i had expressed my problem correctly.
This is my Gulpfile.-
// Include gulp
var gulp = require('gulp');
// Include Our Plugins
var jshint = require('gulp-jshint');
var sass = require('gulp-sass');
var concat = require('gulp-concat');
var uglify = require('gulp-uglify');
var rename = require('gulp-rename');
var THREE = require('three');
gulp.task('build', () =>
gulp.src('app.js')
.pipe(bro({
transform: [
babelify.configure({ presets: ['es2015'] }),
[ 'uglifyify', { global: true } ]
]
})
.pipe(gulp.dest('dist')
)))
gulp.watch('*.js', ['build'])
// Lint Task
gulp.task('lint', function() {
return gulp.src('js/*.js')
.pipe(jshint())
.pipe(jshint.reporter('default'));
});
// Compile Our Sass
gulp.task('sass', function() {
return gulp.src('scss/*.scss')
.pipe(sass())
.pipe(gulp.dest('dist/css'));
});
// Concatenate & Minify JS
gulp.task('scripts', function() {
return gulp.src('js/*.js')
.pipe(concat('all.js'))
.pipe(gulp.dest('dist'))
.pipe(rename('all.min.js'))
.pipe(uglify())
.pipe(gulp.dest('dist/js'));
});
// Watch Files For Changes
gulp.task('watch', function() {
gulp.watch('js/*.js', ['lint', 'scripts']);
gulp.watch('scss/*.scss', ['sass']);
});
// Default Task
gulp.task('default', ['lint', 'sass', 'scripts', 'watch', 'build']);
EDIT: Think i got it, the documentation of a site was not complete, and i didnt knew i had to install Browserify also with gulp-bro, that seems to be the same, anyway that fixed the require problem. (bringing other new ones) Thank you for everything, and hope this helps somebody.
EDIT2: Now i have found out that Rollup.js is a better solution, with Babel, theres Rollup npm s for that, good luck.
Thank you.

gulp plugin - to merge broken js files into one js file?

I have read all the answers on the internet that I could find on this subject in last two days. Now I am just searching for gulp plugin that can merge broken js files into one big js file and not to throw error in terminal caused by unclosed function in one js file.
Explanation:
I have created js app built with modules.
At the very beginning I didn't knew that this will become big app and therefore I have wrote js code in one file.
Now I have come to an idea to split app.js file like this:
app-start.js (Named IIFE function open)
module1.js
module2.js
etc.
app-end.js (Named IIFE function closed)
I am using gulp as task runner and gulp-concat which works perfectly.
Problem is that when I try to break IIFE function in two files (app-start.js, app-end.js) then gulp doesn't wanna build bundle.js file.
I get error in terminal that I should repair my js code in
app-start.js
So, my question is,
do You maybe know about gulp plugin that will merge multiple js files in given order and never mind the js code errors in those files?
This is my gulp.js code:
var gulp = require('gulp'),
sass = require('gulp-sass'),
uglify = require('gulp-uglify'),
plumber = require('gulp-plumber'),
concat = require('gulp-concat'),
imagemin = require('gulp-imagemin'),
pngquant = require('imagemin-pngquant'),
autoprefixer = require('gulp-autoprefixer'),
browserSync = require('browser-sync').create(),
sourceMap = require('gulp-sourcemaps'),
babel = require('gulp-babel');
gulp.task('sass', function() {
gulp.src('resources/sass/config-normalize.sass')
//.pipe(sourceMap.init())
.pipe(sass.sync().on('error', sass.logError))
.pipe(autoprefixer({browsers: ['last 30 versions']}))
.pipe(sass({outputStyle: 'expanded'})) //expanded - compressed
//.pipe(sourceMap.write('.'))
.pipe(gulp.dest('configurator/css'));
gulp.src('resources/sass/config-style.sass')
//.pipe(sourceMap.init())
.pipe(sass.sync().on('error', sass.logError))
.pipe(autoprefixer({browsers: ['last 30 versions']}))
.pipe(sass({outputStyle: 'expanded'})) //expanded - compressed
//.pipe(sourceMap.write('.'))
.pipe(gulp.dest('configurator/css'))
.pipe(browserSync.stream());
});
gulp.task('scripts', function() {
gulp.src([
//'resources/js/vendor/jquery.js',
//'resources/js/vendor/library/neki_file.js',
'resources/js/001-app-start.js',
'resources/js/002-ajax.js',
'resources/js/003-global-variables.js',
'resources/js/050-main.js',
'resources/js/100-my-modules.js',
'resources/js/app-end.js'
])
//.pipe(plumber())
.pipe(babel({
presets: ['es2015']
}))
.pipe(concat('all.js'))
//.pipe(uglify())
.pipe(gulp.dest('configurator/js'))
.pipe(browserSync.stream());
});
gulp.task('php', function() {
gulp.src('./**/*.php')
.pipe(browserSync.stream());
});
gulp.task('browser-sync', function() {
browserSync.init({
proxy: "localhost" //Upisi path do projekta na local hostu bez http://
});
});
gulp.task('images', function() {
return gulp.src('assets/images-uncompressed/**/*')
.pipe(imagemin({
progressive: true,
svgoPlugins: [{removeViewBox: false}],
use: [pngquant()]
}))
.pipe(gulp.dest('build/images'));
});
gulp.task('watch', function() {
gulp.watch('./**/*.php', ['php']);
gulp.watch('resources/sass/**', ['sass']);
gulp.watch('resources/js/**', ['scripts']);
//gulp.watch('resources/images-uncompressed/*', ['images']);
});
gulp.task('default', ['sass', 'scripts', 'php', 'browser-sync', 'watch']);
The problem is with the order you run your Gulp tasks:
babel parses and transforms JavaScript so it needs well-formed input.
concat doesn't need to understand JavaScript; it just combines text files. It will happily deal with your broken-up files.
If you move concat before babel, Babel can work on a single, well-formed blob of JavaScript built up from your split files.

Gulp compiling error js.72. Unhandled error

I just recently copied over my local gulpfile and packages to a server in order to compile sass on the server instead of having to copy the file over everytime I make a change. The gulp tasks worked fine before, but now when I try my gulp css task, I get this error.
Starting 'css'...
events.js:72
throw er; // Unhandled 'error' event
^
Error: Gem undefined is not installed.
Here is my gulpfile. I thought I had all the errors handled, but I guess I missed something. Gulpfiles are so confusing...
var gulp = require('gulp');
var minifycss = require('gulp-cssnano');
var autoprefixer = require('gulp-autoprefixer');
var notify = require('gulp-notify');
var sass = require('gulp-ruby-sass');
var concat = require('gulp-concat');
var sourcemaps = require('gulp-sourcemaps');
gulp.task('css', function() {
return sass('scss/**/*.scss')
.pipe(sourcemaps.init())
.pipe(autoprefixer())
.pipe(concat('ivie2017.css'))
.on('error', sass.logError)
.pipe(sourcemaps.write())
.pipe(gulp.dest('./css'))
.pipe(notify({ message: 'Wait for it....wait for it!!!' }));
});
gulp.task('default', function() {
gulp.watch('scss/**/*.scss',['css']);
});
Run $ npm install --save-dev gulp-ruby-sass to install gulp ruby sass.
https://github.com/sindresorhus/gulp-ruby-sass#install
Ruby gem for Sass was not installed. I ran the command "gem install sass" and afterwards my scss compiled just fine!

Gulp Concat + Browserync restarting

I'm using gulp concat and browserync. When I run gulp, it starts browserync and concatenates and reloads all js files found in modules. The problem is that it only does the concatenation of js files once, so I need to stop running gulp and run it again so I can see any changes reflected to js files. I only see the gulp notify task after stoping and restarting gulp too. How do I setup gulp so that always bundles and compiles the js and then runs browersync?
Here is my gulpfile
var gulp = require('gulp');
var concat = require('gulp-concat');
var browserSync = require('browser-sync').create();
var notify = require('gulp-notify');
// default
gulp.task('default', ['browserSync', 'scripts'], function (){
// Reloads the browser whenever HTML or JS files change
gulp.watch('app/*.html', browserSync.reload);
gulp.watch('app/modules/**/*.js', browserSync.reload);
});
gulp.task('scripts', function() {
return gulp.src('app/modules/**/**.js')
.pipe(concat('main.js'))
.pipe(gulp.dest('app/build/js'))
.pipe(notify({ message: 'Scripts in modules have been bundled!' }));
});
//start browsersync
gulp.task('browserSync', function() {
browserSync.init({
server: {
baseDir: 'app'
},
})
})
Try this:
// watch
gulp.task('watch', ['browserSync', 'scripts'], function (){
// Reloads the browser whenever HTML or JS files change
gulp.watch('app/*.html', browserSync.reload);
gulp.watch('app/modules/**/*.js', ['scripts']);
});
gulp.task('scripts', function() {
return gulp.src('app/modules/**/**.js')
.pipe(concat('main.js'))
.pipe(gulp.dest('app/build/js'))
.pipe(notify({ message: 'Scripts in modules have been bundled!' }))
.pipe(browserSync.reload({
stream: true
}));
});
gulp.task('default', ['watch', 'scripts']);
I'm not sure but could you try to put
gulp.watch('app/modules/**/*.js', ['scripts']);
under task "default"
As I understand your gulp didn't watch your files and run the script
P.S. I'm not expert in gulp if it doesn't work out I'm sorry.
