Jquery library not working after gulp bundle - javascript

I am quite a newbie for gulp but i am trying to implement it in my this project. But looks like somewhere i mashup. I order the js files and was trying to get the bundle. But looks like jquery lib or something is not working.
Here is my gulpfile.js code:
'use strict';
// include all necessary plugins in gulp file
var gulp = require('gulp');
var order = require('gulp-order');
var concat = require('gulp-concat');
var sass = require('gulp-sass');
var sourcemaps = require('gulp-sourcemaps');
var uglify = require('gulp-uglify');
var rename = require('gulp-rename');
var imagemin = require('gulp-imagemin');
var cache = require('gulp-cache');
// Task defined for java scripts bundling and minifying
gulp.task('scripts', function() {
return gulp.src('assets/src/js/*.js')
.pipe(order([
"assets/src/js/jquery-3.2.1.slim.min.js",
"assets/src/popper.min.js",
"assets/src/js/bootstrap.min.js",
"assets/src/js/morphext.min.js",
"assets/src/js/pushy.min.js",
"assets/src/quote.js"
], { base: './' }))
.pipe(concat('bundle.js'))
.pipe(rename({suffix: '.min'}))
.pipe(uglify())
.pipe(gulp.dest('assets/dist/js'));
});
// Task define for compliling scss file
// Currently i am not using this complier
gulp.task('sass', function() {
return gulp.src('assets/src/css/**/*.scss', {style: 'compressed'})
.pipe(rename({suffix: '.min'}))
.pipe(sourcemaps.init()) // Process the original sources
.pipe(sass())
.pipe(sourcemaps.write()) // Add the map to modified source.
.pipe(gulp.dest('assets/dist/css/'));
});
// Define task to optimize images in project
gulp.task('images', function() {
return gulp.src('assets/src/img/**/*')
.pipe(cache(imagemin({ optimizationLevel: 5, progressive: true, interlaced: true })))
.pipe(gulp.dest('assets/dist//img'));
});
// Task watch
gulp.task('watch', function() {
// Watch .js files
gulp.watch('assets/src/js/*.js', ['scripts']);
// Watch .scss files
gulp.watch('assets/src/css/*.scss', ['sass']);
// Watch image files
gulp.watch('assets/src/img/**/*', ['images']);
});
// declaring final task and command tasker
// just hit the command "gulp" it will run the following tasks...
gulp.task('default', ['scripts', 'images' , 'watch']);

I got solution for this problem, here is my new code for gulp.js!
'use strict';
// include all necessary plugins in gulp file
var gulp = require('gulp');
var concat = require('gulp-concat');
var sass = require('gulp-sass');
var sourcemaps = require('gulp-sourcemaps');
var uglify = require('gulp-uglify');
var rename = require('gulp-rename');
var imagemin = require('gulp-imagemin');
var cache = require('gulp-cache');
// Task defined for java scripts bundling and minifying
gulp.task('scripts', function() {
return gulp.src
([
'assets/src/js/jquery/*.js',
'assets/src/js/vendor/*.js',
'assets/src/js/plugins/*.js',
'assets/src/js/custom/*.js',
])
.pipe(concat('bundle.js'))
.pipe(rename({suffix: '.min'}))
.pipe(uglify())
.pipe(gulp.dest('assets/dist/js/'));
});
// Task define for compliling scss file
gulp.task('sass', function() {
return gulp.src('assets/src/scss/**/*.scss', {style: 'compressed'})
.pipe(rename({suffix: 'custom'}))
.pipe(sourcemaps.init()) // Process the original sources
.pipe(sass())
.pipe(sourcemaps.write()) // Add the map to modified source.
.pipe(gulp.dest('assets/dist/css/unminified/'));
});
// Define task to optimize images in project
gulp.task('images', function() {
return gulp.src('assets/src/img/**/*')
.pipe(cache(imagemin({ optimizationLevel:5, progressive: true, interlaced: true })))
.pipe(gulp.dest('assets/dist/img'));
});
// Task watch
gulp.task('watch', function() {
// Watch .js files
gulp.watch('assets/src/js/*.js', ['scripts']);
// Watch .scss files
gulp.watch('assets/src/scss/*.scss', ['sass']);
// Watch image files
gulp.watch('assets/src/img/**/*', ['images']);
});
// declaring final task and command tasker

gulp.task('default', ['scripts', 'images' , 'sass' , 'watch']);

Browsersync works only on second save

I never encountered this issue before cause I worked with one-page websites. But now I have several pages, and when I created third file in 'build' folder, browsersync started to work not as expected.
Basically, browsersync now makes changes in browser only on second save. You can see this behavior on video: https://youtu.be/lNFEDZMBiQY
Here's my gulp setup:
// Gulp.js configuration
var
// modules
gulp = require('gulp'),
sass = require('gulp-sass'),
pug = require('gulp-pug'),
concat = require('gulp-concat'),
//uglify = require('gulp-uglify'),
browserSync = require('browser-sync').create()
// browserSync
gulp.task('browserSync', function() {
browserSync.init({
server: {
baseDir: 'build',
directory: true
},
notify: false
})
})
// pug to html
gulp.task('pug', function buildHTML() {
return gulp.src('src/pug/*.pug')
.pipe(pug())
.pipe(gulp.dest('build/'))
.pipe(browserSync.reload({
stream: true
}))
});
// scss to css
gulp.task('sass', function(){
return gulp.src('src/scss/style.scss')
.pipe(sass()) // Converts Sass to CSS with gulp-sass
.pipe(gulp.dest('build/css'))
.pipe(browserSync.reload({
stream: true
}))
});
// js concat and minify
gulp.task('scripts', function() {
return gulp.src(['src/js/jquery-3.0.0.min.js', 'src/js/jquery-migrate-1.4.1.min.js', 'src/js/swiper.min.js', 'src/js/jquery.photoswipe-global.js', 'src/js/custom.js'])
.pipe(concat('main.min.js'))
//.pipe(uglify())
.pipe(gulp.dest('build/js/'));
});
// watcher
gulp.task('watch', ['browserSync', 'sass', 'pug', 'scripts'], function(){
gulp.watch('src/scss/**/*.scss', ['sass']);
gulp.watch('src/pug/**/*.pug', ['pug']);
gulp.watch('src/js/**/*.js', ['scripts']);
// Other watchers
})
gulp.task('default', ['watch']);
Maybe, there's an error in this setup? How I can fix this issue?

Task 'sass' is not in your Gulpfile - ERROR

Following is the code I am facing this error please help me solve this, i would be really graced to get clear answer ___
Everything runs smooth but except if I save the file, following error occurs
ERROR : Task 'sass' is not in your gulpfile

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

});

gulp.task('watch', function() {
gulp.watch('./src/js/*.js', ['scripts']);
gulp.watch('./src/sass/*.scss', ['styles']);
});
// image minification
gulp.task('imagemin', function() {
var imgSrc = './src/img/**/*',
imgDst = './dist/img';
gulp.src(imgSrc)
.pipe(changed(imgDst))
.pipe(imagemin())
.pipe(gulp.dest(imgDst));
});
gulp.task('default', ['scripts', 'styles', 'browser-sync', 'imagemin', 'watch']);
You do not have, indeed, defined "sass" task nor "scss" task thats marked as dependable under "browser-sync" file.
Try Replacing:
gulp.watch("./src/sass/*.scss", ['scss']);
with
gulp.watch("./src/sass/*.scss", ['styles']);

Error in gulp while copying files

My command line shows following error while i entered the gulp watch command. Since gulp is searching css files from inside the app directory instead of searching it from bower_components.I have tried using minify-css as well as copy-css.Both are not working.

Gulp file not compiling less file to css

I have a gulp file, and when I run it only the JavaScript files get complied and the less files doesn't get compiled, and I cannot seem to understand why is this happening.
This is my gulp file:
'use strict';
var path = require('path');
var gulp = require('gulp');
var concat = require('gulp-concat');
var sourcemaps = require('gulp-sourcemaps');
var less = require('gulp-less');
var watch = require('gulp-watch');
var jshint = require('gulp-jshint');
var jscs = require('gulp-jscs');
var livereload = require('gulp-livereload');
var jsFiles = ['*.js', 'src/**/*.js'];
// js hints
gulp.task('hints', function(){
return gulp.src(jsFiles)
.pipe(jshint())
.pipe(jshint.reporter('jshint-stylish', {
verbose: true
}))
.pipe(jscs()); });
// less
gulp.task('less', function () {
return gulp.src('./public/src/less/main.less')
.pipe(less({ paths: [path.join(__dirname, 'less', 'includes')] }))
.pipe(gulp.dest('./public/src/less/css')); });
// concat
gulp.task('concat', ['concat:css', 'concat:js']); gulp.task('concat:css', function() {
return gulp.src([
'public/lib/bower_components/bootstrap/dist/css/bootstrap.min.css',
'public/lib/bower_components/swiper/dist/css/swiper.min.css',
'public/lib/bower_components/font-awesome/css/font-awesome.min.css',
'public/src/less/css/main.css'
])
.pipe(concat('styles.css'))
.pipe(gulp.dest('./public/build/')); }); gulp.task('concat:js', function() {
return gulp.src([
'public/lib/bower_components/jquery/dist/jquery.min.js',
'public/lib/bower_components/bootstrap/dist/js/bootstrap.min.js',
'public/lib/bower_components/swiper/dist/js/swiper.min.js',
'public/lib/bower_components/jquery.scrollTo/jquery.scrollTo.min.js',
'public/lib/bower_components/jquery.localScroll/jquery.localScroll.min.js',
'public/lib/bower_components/jquery-waypoints/lib/jquery.waypoints.min.js',
'public/lib/bower_components/gsap/src/uncompressed/TweenMax.js',
'public/lib/bower_components/scrollmagic/scrollmagic/uncompressed/ScrollMagic.js',

'public/lib/bower_components/scrollmagic/scrollmagic/uncompressed/plugins/debug.addIndicators.js',
'public/src/js/init.js',
'public/src/js/utils.js',
'public/src/js/main.js'
])
.pipe(concat('scripts.js'))
.pipe(gulp.dest('./public/build/')); });
// watch
gulp.task('watch', ['watch:css', 'watch:js']);
gulp.task('watch:css', function () {
gulp.watch('public/src/less/*.less', ['less', 'concat:css']);
});
gulp.task('watch:js', function () {
gulp.watch('public/src/js/*.js', ['concat:js', 'hints']);
});
gulp.task('build', [ 'less', 'concat']);
gulp.task('development', [ 'less', 'concat', 'watch']);
When I run gulp development the css and js file gets created under the build folder but because the less files dont get compiled to css the css file under build folder has none of my styles.
Does someone know how to solve this issue?
Thank you

Update: Errors with postCSS and Babel in Gulpfile

Goal
I'm updating my old gulpfile.js, which used to be mainly for compiling my Sass into CSS, but now I'm trying to get Gulp to do the following:
Sync browser, whip up localhost server - DONE
Compile Sass => CSS - DONE
Show any JavaScript errors with JSHint - DONE
Compile ES6 => ES6 with Babel (WORKING ON)
Minify all assets (WORKING ON)
Show project file size - DONE
Deploy index.html, style.css and images to S3 (WORKING ON)
Watch files, reload browser when .scss or .html changes - DONE
Problem
Trying to minify my Javascript and also create a scripts.min.js
file, it keeps adding the suffix min to every new minified JavaScript
file.
Folder structure
index.html
gulpfile.js
package.json
.aws.json
.csscomb.json
.gitignore
assets
- css
style.css
style.scss
--partials
---base
---components
---modules
- img
- js
scripts.js
- dist

Hi i can't solve all your problems but I had also a similar issue with the babel and ES6 fat arrow functions (using babelify and browserify). To solve the problem try to pass:
stage: 0
to your babel.js gulp plugin. If error will still occurs then try to pass also:
experimental: true
For more information please have a look "experimental" section on babel.js site.
