Gulp bundle then minify - gulp

I'm creating 3 minified bundles for my application. I have 2 tasks to do this, minify, and bundle. Minify has a dependency on bundle. If I run minify, both tasks run with no errors. The bundles are created, but the minified files are not. If I remove the dependency on bundle, I can then run minify by itself and the minified files are created successfully. This leads me to believe maybe the files are in use when the minify task triggers (because bundle hasn't finished?). How do I cause it to wait until the files are fully ready? Can I pass the stream? Or maybe combine these into a single task? The reason they are not currently a single task is because they output 2 files per bundle (an unminified and a minified bundle).
var outFolder = __dirname + '\\Scripts\\dist';
var appBundles = [
{ scripts: ['Scripts/Common/**/*.js'], output: 'eStore.common.js' },
{ scripts: ['Scripts/Checkout/**/*.js'], output: 'eStore.checkout.js' },
{ scripts: ['Scripts/ProductDetail/**/*.js'], output: 'eStore.product.js' }
];
gulp.task('bundle', bundle);
gulp.task('minify', ['bundle'], minify); // this one doesn't work
gulp.task('minifyOnly', minify); // this one works
function bundle() {
appBundles.forEach(function (appBundle) {
gulp.src(appBundle.scripts)
.pipe(concat(appBundle.output))
.pipe(sourcemaps.init())
.pipe(sourcemaps.write(outFolder + '\\maps'))
.pipe(gulp.dest(outFolder))
.on('error', errorHandler);
});
}
function minify() {
appBundles.forEach(function(appBundle) {
var bundleSrc = outFolder + '\\' + appBundle.output;
gulp.src(bundleSrc)
.pipe(rename({ extname: '.min.js' }))
.pipe(uglify())
.pipe(gulp.dest(outFolder))
.on('error', errorHandler);
});
}

Have the minify task use the same source files that the bundle task uses. 'concat' will be used in both tasks. This way minify doesn't have a dependency on the output from the bundle task.
function minify() {
appBundles.forEach(function (appBundle) {
console.log('Creating minified bundle for: ' + appBundle.output);
gulp.src(appBundle.scripts)
.pipe(concat(appBundle.output))
.pipe(rename({ extname: '.min.js' }))
.pipe(uglify())
.pipe(gulp.dest(outFolder))
.on('error', errorHandler);
});
}
function bundle() {
appBundles.forEach(function (appBundle) {
console.log('Creating bundle and sourcemaps: ' + appBundle.output);
gulp.src(appBundle.scripts)
.pipe(concat(appBundle.output))
.pipe(sourcemaps.init())
.pipe(sourcemaps.write(outFolder + '\\maps'))
.pipe(gulp.dest(outFolder))
.on('error', errorHandler);
});
}

Use Gulp To Copy File Into Directory Named After Filename

I have the following files
assets
---views
------pages
---------some_page.ejs
---------another_page.ejs
When I build these ejs files, I want them to go into the following file structure
public
---some_page
------index.html
---another_page
------index.html
My gulp file contains the following build command:
gulp.task('build-html', function() {
return gulp.src('assets/views/pages/*.ejs')
.pipe(ejs())
.pipe(gulp.dest('public/???')); // WHAT DO I ADD HERE TO MAKE ABOVE WORK?
});
I'm totally stumped what I need to add into the gulp.dest function to achieve the above.
Solved with gulp-rename package:
gulp.task('build-html', function() {
return gulp.src('assets/views/pages/*.ejs')
.pipe(ejs())
.pipe(rename(function (path) {
path.dirname += "/" + path.basename;
path.basename = "index";
}))
.pipe(gulp.dest('public/'));
});

foundation-sites 6 replacing panini for jekyll

I'm looking to extend a zurb foundation for sites 6 site and use jekyll instead of panini to render the HTML. I'm using the out of the box ZURB foundation prototype template that includes ES6 + webpack. I want foundation to handle all the SASS and JS compiling and I also want to retain the browsersync functionality. I just want to know the best approach for modifying the gulp file to integrate jekyll, this is so I can work with GitHub Pages.
Here is what the default gulp.babel.js file looks like:
'use strict';
import plugins from 'gulp-load-plugins';
import yargs from 'yargs';
import browser from 'browser-sync';
import gulp from 'gulp';
import panini from 'panini';
import rimraf from 'rimraf';
import sherpa from 'style-sherpa';
import yaml from 'js-yaml';
import fs from 'fs';
import webpackStream from 'webpack-stream';
import webpack2 from 'webpack';
import named from 'vinyl-named';
// Load all Gulp plugins into one variable
const $ = plugins();
// Check for --production flag
const PRODUCTION = !!(yargs.argv.production);
// Load settings from settings.yml
const { COMPATIBILITY, PORT, UNCSS_OPTIONS, PATHS } = loadConfig();
function loadConfig() {
let ymlFile = fs.readFileSync('config.yml', 'utf8');
return yaml.load(ymlFile);
}
// Build the "dist" folder by running all of the below tasks
gulp.task('build',
gulp.series(clean, gulp.parallel(pages, sass, javascript, images, copy), styleGuide));
// Build the site, run the server, and watch for file changes
gulp.task('default',
gulp.series('build', server, watch));
// Delete the "dist" folder
// This happens every time a build starts
function clean(done) {
rimraf(PATHS.dist, done);
}
// Copy files out of the assets folder
// This task skips over the "img", "js", and "scss" folders, which are parsed separately
function copy() {
return gulp.src(PATHS.assets)
.pipe(gulp.dest(PATHS.dist + '/assets'));
}
// Copy page templates into finished HTML files
function pages() {
return gulp.src('src/pages/**/*.{html,hbs,handlebars}')
.pipe(panini({
root: 'src/pages/',
layouts: 'src/layouts/',
partials: 'src/partials/',
data: 'src/data/',
helpers: 'src/helpers/'
}))
.pipe(gulp.dest(PATHS.dist));
}
// Load updated HTML templates and partials into Panini
function resetPages(done) {
panini.refresh();
done();
}
// Generate a style guide from the Markdown content and HTML template in styleguide/
function styleGuide(done) {
sherpa('src/styleguide/index.md', {
output: PATHS.dist + '/styleguide.html',
template: 'src/styleguide/template.html'
}, done);
}
// Compile Sass into CSS

.pipe($.if(!PRODUCTION, $.sourcemaps.write()))
.pipe(gulp.dest(PATHS.dist + '/assets/css'))
.pipe(browser.reload({ stream: true }));
}
let webpackConfig = {
rules: [
{
test: /.js$/,
use: [
{
loader: 'babel-loader'
}
]
}
]
}
// Combine JavaScript into one file
// In production, the file is minified
function javascript() {
return gulp.src(PATHS.entries)
.pipe(named())
.pipe($.sourcemaps.init())
.pipe(webpackStream({module: webpackConfig}, webpack2))
.pipe($.if(PRODUCTION, $.uglify()
.on('error', e => { console.log(e); })
))
.pipe($.if(!PRODUCTION, $.sourcemaps.write()))
.pipe(gulp.dest(PATHS.dist + '/assets/js'));
}
// Copy images to the "dist" folder
// In production, the images are compressed
function images() {
return gulp.src('src/assets/img/**/*')

I assume as part of the jekyll build/rebuild I would need to use the keep-files config setting so when jekyll clobbers the output directory file don't get overwritten.
Appreciate any help
Thanks
Jekyll is a different solution than Panini and uses Ruby
https://jekyllrb.com/docs/installation/
In general you might need some git hook or Travis config.

Gulp watch not putting files in the right directory

Here is my gulp watch task, the only issue is that the transpiled files are ending up directly in build/ as opposed to in build/original/path/ - how can I preserve the path structure when the files are transpiled to the build/ dir?
gulp.task('transpile-watch-js', function () {
return gulp.watch('lib/**/*.js', function (obj) {
if (obj.type === 'changed') {
gulp.src(obj.path)
.pipe(babel())
.pipe(gulp.dest('build'));
}
});
});
Use gulp.src with the base option.
Examples, considering your sourcefiles path matches the pattern 'folder1/folder2/folder3/*.js'
If you write:
gulp.src(obj.path, {base: '.'})
gulp.dest('build') will write in build/folder1/folder2/folder3/
gulp.src(obj.path, {base: './folder1'})
gulp.dest('build') will write in build/folder2/folder3/
gulp.src(obj.path, {base: './folder1/folder2'})
gulp.dest('build') will write in build/folder3/
And so on.

Gulp dependant task not working properly

I have two gulp tasks, one to compile stylus files and the other is to clean my css files but I don't understand why only clean-styles run when I executed the command: gulp styles on the terminal.
gulp.task("clean-styles", function (done) {
clean(config.css + "**/*.css", done);
});
gulp.task("styles", ["clean-styles"], function () {
return gulp.src(config.styles)
.pipe($.plumber())
.pipe($.stylus())
.pipe(gulp.dest(config.css));
});
function clean(path, done) {
del(path, done);
}
I"m using Gulp version 3.9.0 I've done this on multiple project in the past and it seems to be working.
I'm not sure what I'm doing wrong. There are no errors in the console.
Expected Result:
I expect styles to run after the clean-styles task.
Actual Result: Only clean-styles run.
Thanks #kombucha for the heads up. It seems to be a change in the del package which caused this to no longer work.
gulp.task("clean-styles", function (done) {
clean(config.css + "**/*.css", done);
});
gulp.task("styles", ["clean-styles"], function () {
return gulp.src(config.styles)
.pipe($.plumber())
.pipe($.stylus())
.pipe(gulp.dest(config.css));
});
New Clean function:
function clean(path, done) {
del(path).then(function (paths) {
console.log("Cleaning: " + paths);
done();
});
}

Gulp to combine bower files

I'm aware this has probably been asked before, but I can't seem to be able to ask Google the right questions to find what I need. So I'm possibly thinking about this in the wrong way.
Basically, I need to know if there is a way to use Gulp with Bower so that all css files in subdirectories under bower_components are combined into one styles.css, all js files in subdirectories under bower_components are combined into one scripts.js. Kind of how assetic works in symfony2 to combine assets into single files. Does each 'built' file in each bower_componets subdirectory have to be linked to manually (in the Gulp config file), or is it more common to loop through them programatically?
Thanks
Would something like the below help? It loops through all css files in my 'src' directory and spits out one css file in the 'dist' folder. It does the same for my js files:
// Config
var requireJsRuntimeConfig = vm.runInNewContext(fs.readFileSync('src/app/require.config.js') + '; require;');
requireJsOptimizerConfig = merge(requireJsRuntimeConfig, {
out: 'scripts.js',
baseUrl: './src',
name: 'app/startup',
paths: {
requireLib: 'bower_modules/requirejs/require'
},
include: [
'requireLib',
'components/nav-bar/nav-bar',
'components/home-page/home',
'text!components/about-page/about.html'
],
insertRequire: ['app/startup'],
bundles: {
// If you want parts of the site to load on demand, remove them from the 'include' list
// above, and group them into bundles here.
// 'bundle-name': [ 'some/module', 'another/module' ],
// 'another-bundle-name': [ 'yet-another-module' ]
}
});
// Discovers all AMD dependencies, concatenates together all required .js files, minifies them
gulp.task('js', function () {
return rjs(requireJsOptimizerConfig)
.pipe(uglify({ preserveComments: 'some' }))
.pipe(gulp.dest('./dist/'));
});
// Concatenates CSS files, rewrites relative paths to Bootstrap fonts, copies Bootstrap fonts
gulp.task('css', function () {
var bowerCss = gulp.src('src/bower_modules/components-bootstrap/css/bootstrap.min.css')
.pipe(replace(/url\((')?\.\.\/fonts\//g, 'url($1fonts/')),
appCss = gulp.src('src/css/*.css'),
combinedCss = es.concat(bowerCss, appCss).pipe(concat('css.css')),
fontFiles = gulp.src('./src/bower_modules/components-bootstrap/fonts/*', { base: './src/bower_modules/components-bootstrap/' });
return es.concat(combinedCss, fontFiles)
.pipe(gulp.dest('./dist/'));
});
there is a way and its honestly really simple. you can install "gulp-run" to your npm devDependencies and then use the run to execute bower install.
var gulp = require('gulp'),
del = require('del'),
run = require('gulp-run'),
sass = require('gulp-sass'),
cssmin = require('gulp-minify-css'),
browserify = require('browserify'),

concat = require('gulp-concat'),
jshint = require('gulp-jshint'),
browserSync = require('browser-sync'),
source = require('vinyl-source-stream'),
buffer = require('vinyl-buffer'),
reactify = require('reactify'),
package = require('./package.json'),
reload = browserSync.reload;

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

})
/**

.task('server', function() {
browserSync({
server: {
baseDir: './'
}
});
})
/**

.task('sass', function() {
return gulp.src(package.paths.sass)

})
.task('sass:min', function() {
return gulp.src(package.paths.sass)

.pipe(concat(package.dest.style))
.pipe(cssmin())
.pipe(gulp.dest(package.dest.lib));
})
/**

.task('js', function() {
return browserify(package.paths.app)
.transform(reactify)
.bundle()
.pipe(source(package.dest.app))
.pipe(gulp.dest(package.dest.lib));
})
.task('js:min', function() {
return browserify(package.paths.app)
.transform(reactify)
.bundle()
.pipe(source(package.dest.app))
.pipe(buffer())
.pipe(uglify())
.pipe(gulp.dest(package.dest.lib));
})
/**
* Compiling resources and serving application
*/
.task('serve', ['bower', 'clean', 'lint', 'sass', 'js', 'server'], function() {
return gulp.watch([
package.paths.js, package.paths.jsx, package.paths.html, package.paths.sass
], [
'lint', 'sass', 'js', browserSync.reload
]);
})
.task('serve:minified', ['bower', 'clean', 'lint', 'sass:min', 'js:min', 'server'], function() {
return gulp.watch([

], [
'lint', 'sass:min', 'js:min', browserSync.reload
]);
});
what is really beautiful with this setup I just posted is this is making a custom gulp run called "serve" that will run your setup with a development server (with live reload and much better error intelligence) all you have to do is go to your directory and type "gulp serve" and it'll run bower install and build everything for you. obviously the folder structure is different so you will need to make some modifications, but hopefully this shows how you can run bower with gulp :)
Something like the below was what I was looking for, except I don't like having to add the paths manually. This is why I prefer something like CommonJS for Javascript. I definitely remember seeing a way in which CSS files were picked up automatically from the bower_components folder, I believe it was in the Wordpress Roots project (based on the settings/overrides in bower.json).
gulp.task('css', function () {
var files = [
'./public/bower_components/angular-loading-bar/build/loading-bar.css',
'./public/bower_components/fontawesome/css/font-awesome.css'
];
return gulp.src(files, { 'base': 'public/bower_components' })
.pipe(concat('lib.css'))
.pipe(minifyCss())
.pipe(gulp.dest('./public/build/css/')
);
});
gulp.task('js-lib', function () {
var files = [
'public/bower_components/jquery/dist/jquery.js',
'public/bower_components/bootstrap-sass/assets/javascripts/bootstrap.js'
];
return gulp.src(files, { 'base': 'public/bower_components/' })
.pipe(sourcemaps.init())
.pipe(uglify({ mangle: false }))
.pipe(concat('lib.js'))
.pipe(sourcemaps.write('./'))
.pipe(gulp.dest('./public/build/js/')
);
});
You can use gulp-main-bower-files library to add the main files of packages in .bower.json instead to declare them manually
