i new with gulp and i have a problem that i can't know why.
I want to minify my js and css, with the code below, works, but only works if i call minify-js and minify-css into default.
Gulp watch not work and i don't know why.
If a delete the .min with watch running, he creates the .min file, but came empty. All problems i have found came with solutions that my code already have.
var css = [
'./css/estilo.css'
];
var js = [
'./js/app.js'
];
var gulp = require('gulp');
var jsmin = require('gulp-jsmin');
var rename = require('gulp-rename');
var uglify = require("gulp-uglify");
var concat = require("gulp-concat");
var watch = require('gulp-watch');
var cssmin = require("gulp-cssmin");
var stripCssComments = require('gulp-strip-css-comments');
gulp.task('minify-css', function(){
gulp.src(css)
.pipe(stripCssComments({all: true}))
.pipe(cssmin())
.pipe(rename({suffix: '.min'}))
.pipe(gulp.dest('./css/min/'));
});
gulp.task('minify-js', function () {
gulp.src(js)
.pipe(jsmin())
.pipe(rename({suffix: '.min'}))
.pipe(gulp.dest('./js/min/'));
});
gulp.task('default', function() {
gulp.start('watch');
});
gulp.task('watch', function() {
gulp.watch(js, ['minify-js']);
gulp.watch(css, ['minify-css']);
});
Change
gulp.task('default', function() {
gulp.start('watch');
});
to:
gulp.task('default', ['watch']);
This will set the default task's dependency as watch, running watch when default is called.
Also, instead of running gulp, you can run gulp watch to start watching your files. If you make a change to ./css/estilo.css or ./js/app.js, gulp will change it automatically.
Make sure safe write is turned off in your editor (if you use JetBrains this guide should work), and the /css and /min directories have been created.

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.
i am currently learning about gulp.js.
as i saw the tutorial and documentation of gulp.js, this code:
gulp.src('js/*.js')
.pipe(uglify())
.pipe(gulp.dest('minjs'));
makes the uglified javascript file with create new directory named 'minjs'. of course, i installed gulp-uglity with --dev-save option. there is no error message on the console so i don't know what is the problem. i tried gulp with "sudo", but still not working.
so i went to the root directory and searched all filesystem but there is no file named 'minjs' so i guess it just not working. why this is happening? anyone knows this problem, it would be nice why this is happening.
whole source code:
var gulp = require('gulp');
var uglify = require('gulp-uglify');
gulp.task('default', function() {
console.log('mifying scripts...');
gulp.src('js/*.js')
.pipe(uglify())
.pipe(gulp.dest('minjs'));
});
I had the same problem; you have to return the task inside the function:
gulp.task('default', function() {
return gulp.src("js/*.js")
.pipe(uglify())
.pipe(gulp.dest('minjs'));
Also, minjs will not be a file, but a folder, where all your minified files are going to be saved.
Finally, if you want to minify only 1 file, you can specify it directly, the same with the location of the destination.
For example:
var gulp = require('gulp');
var browserify = require('browserify');
var source = require('vinyl-source-stream');
var uglify = require('gulp-uglify');
gulp.task('browserify', function() {
return browserify('./src/client/app.js')
.bundle()
// Pass desired output filename to vinyl-source-stream
.pipe(source('main.js'))
// Start piping stream to tasks!
.pipe(gulp.dest('./public/'));
});
gulp.task('build', ['browserify'], function() {
return gulp.src("./public/main.js")
.pipe(uglify())
.pipe(gulp.dest('./public/'));
});
Hope it helps!
Finally I resolved the question like this:
It was a directory mistake so the gulp task hasn't matched any files; then it couldn't create the dest directory (because no files in output).
const paths = {
dest: {
lib: './lib',
esm: './esm',
dist: './dist',
},
styles: 'src/components/**/*.less',
scripts: ['src/components/**/*.{ts,tsx}', '!src/components/**/demo/*.{ts,tsx}'],
};
At first my scripts was ['components/**/*.{ts,tsx}', '!components/**/demo/*.{ts,tsx}']
And that hasn't matched any files.
I'm using Gulp to dome some tasks on my SCSS and CSS. Now the problem is that when I run Gulp it's starting the watch but nothing is happening: no css is being created. I triple checked the folder structure and it's can.
This is my code:
var gulp = require('gulp');
var plumber = require('gulp-plumber');
var sass = require('gulp-sass');
var autoprefixer = require('gulp-autoprefixer');
var minifycss = require('gulp-minify-css');
var rename = require('gulp-rename');
var watch = require('gulp-watch');
gulp.task('sass', function () {
return gulp.src('resources/assets/sass/**/*.scss')
.pipe(plumber())
.pipe(sass({errLogToConsole: true}))
.pipe(autoprefixer({browsers: ['last 2 version']}))
.pipe(rename({suffix: '.min'}))
.pipe(minifycss())
.pipe(gulp.dest('./public/css'))
});
gulp.task('default', function () {
watch('resources/assets/sass/**/*.scss', function () {
gulp.start('sass');
});
});
Temporary Solution
After a long search with some people it's just PHPStorm that's not showing the updated file. The file has to be accessed first. It's like a sort of caching.
When I save the .scss file, and immediatly open it with notepad, or access a php file which uses the file, then it also updates in PHPStorm.
Try this one
var gulp = require('gulp');
var plumber = require('gulp-plumber');
var sass = require('gulp-sass');
var autoprefixer = require('gulp-autoprefixer');
var minifycss = require('gulp-minify-css');
var rename = require('gulp-rename');
gulp.task('sass', function () {
return gulp.src('resources/assets/sass/**/*.scss')
.pipe(plumber())
.pipe(sass({errLogToConsole: true}))
.pipe(autoprefixer({browsers: ['last 2 version']}))
.pipe(rename({suffix: '.min'}))
.pipe(minifycss())
.pipe(gulp.dest('./public/css'))
});
gulp.task('default', function () {
gulp.watch('resources/assets/sass/**/*.scss', ['sass']);
});
I don't think you really need another plugin to complie your sass files, gulp.watch works just fine.
So basically what I am doing here is, I am just telling gulp to watch all the sass files in that folder and whenever there's a change, just run the task in the given array ['sass'].
The solution is a PHPStorm Setting
It seems that PHPStorm uses a form of file caching, that's why I didn't see the reflected changes. The solution can be found here!
How to prevent phpstorm to reload file without prompt when file on disk is changed?
I have a gulpfile.js that looks like this:
var gulp = require('gulp'),
concat = require('gulp-concat'),
less = require('gulp-less'),
minifyCSS = require('gulp-minify-css'),
uglify = require('gulp-uglify'),
autoprefixer = require('gulp-autoprefixer');
gulp.task('less', function () {
gulp.src(['less/*.less'])
.pipe(less())
.pipe(concat('everything.css'))
.pipe(autoprefixer())
.pipe(minifyCSS())
.pipe(gulp.dest('asset/'));
});
gulp.task('js', function () {
gulp.src(['javascript/*.js'])
.pipe(concat('everything.js'))
.pipe(uglify())
.pipe(gulp.dest('asset/'));
});
gulp.task('watch', function() {
gulp.watch('javascript/*.js', ['js']);
gulp.watch('less/*.less', ['less']);
});
As I was developing, the less task stopped working out of the blue. The console doesn't throw any errors, everything looks just like it should but the everything.css file does not get updated. I even removed the file and it doesn't get created again.
I'm compeltely clueless to what's going on, even rebooted my computer as a sanity check but it didn't help.
EDIT:
So apparently it's the less pipe. But why did it start to fail suddenly?
Try updating your less files a bit, to simplify. This is a common design pattern, and it works very well for me:
/*main.less*/
#import "somefile.less"
#import "some/deep/nested/file.less"
In your other less files, those will be where you keep your actuall less code.
Then in your gulpfile.js you will want to modify a bit:
...
gulp.task('less', function () {
gulp.src(['less/main.less']) //only pull in your main.less file
.pipe(less())
.pipe(autoprefixer())
.pipe(minifyCSS())
.pipe(gulp.dest('asset/'));
});
...
gulp.task('watch', function() {
gulp.watch('javascript/*.js', ['js']);
gulp.watch('less/*.less', ['less']); //this remains the same - you want to watch for all changes
});
Note: gulp.watch will not find new files - you will need to restart when you have new files, or use something like gulp-watch.
This will solve all kinds of headaches for you. Hope it helps!
I have a simple gulpfile that loads a javascript object from a json file (to get paths based on environment), compiles my scss files, moves them to my public directory, and also moves any javascript files to the public directory.
So my assets in /app/Http/assets/js and scss
are compiled and moved to /public/assets/js and css
Here is my gulpfile.js:
var gulp = require('gulp');
var gutil = require('gulp-util');
var notify = require('gulp-notify');
var sass = require('gulp-sass');
var autoprefix = require('gulp-autoprefixer');
// Load the application config
var config = require('./env.config.json');
// Where do you store your Sass files?
var sassDir = 'app/Http/Assets/scss';
// Which directory should Sass compile to?
var targetCSSDir = config.assets_path + '/css';
// Where do you store your CoffeeScript files?
var jsDir = 'app/Http/Assets/js';
// Which directory should CoffeeScript compile to?
var targetJSDir = config.assets_path + '/js';
/** Tasks **/
// Compile Sass, autoprefix CSS3, and save to target CSS directory
gulp.task('css', function () {
return gulp.src(sassDir + '/**/*.scss')
.pipe(sass())
.pipe(autoprefix('last 10 version'))
.pipe(gulp.dest(targetCSSDir))
.pipe(notify('CSS minified'))
});
// Move Javascript
gulp.task('js', function () {
return gulp.src(jsDir + '/**/*.js')
.pipe(gulp.dest(targetJSDir))
});
// Keep an eye on Sass and Javascript files for changes...
gulp.task('watch', function () {
gulp.watch(sassDir + '/**/*.scss', ['css']);
gulp.watch(jsDir + '/**/*.js', ['js']);
});
// What tasks does running gulp trigger?
gulp.task('default', ['css', 'js', 'watch']);
This is working fine for my javascript. Also, when I run "gulp" the first time, it compiles all my scss files and moves them accordingly. However, the watch task is not working for my scss files. It DOES work for javascript files. What's really weird (to me) is that when I change my scss source to a specific file, the watch works. So,
gulp.task('css', function () {
return gulp.src(sassDir + '/**/app.scss')
.pipe(sass())
// and the rest is the same
will watch AND compile any changes to my app.scss file, but obviously not to any other scss files.
I have re-arranged and googled all I can. I don't understand why it won't work for watching scss.
EDIT: Strangely, it seems to be notify that is breaking the css watcher. When I comment it out like so:
gulp.task('css', function () {
return gulp.src(sassDir + '/**/*.scss')
.pipe(sass())
.pipe(autoprefix('last 10 version'))
.pipe(gulp.dest(targetCSSDir))
//.pipe(notify('CSS minified'))
});
everything works as expected.
Thanks in advance.
