How to temporarily disable browsersync? - livereload

How can I temporarily disable browsersync, so that it doesn't inject/modify HTML pages? (For testing and debugging.)

There doesn't seem to be a configuration option to do just this, but one hacky workaround is to use snippetOptions to specify a string that will will never be found in the HTML:
snippetOptions: {
rule: {
match: /qqqqqqqqq/
}
}
If this string cannot be found in the HTML, the snippet will never be injected, and browsersync will be inert.

You can use Yargs to send parameters and enable or disable 'watch' task.
Remember this command line to install required components:
npm i --save gulp browser-sync yargs runSequence
On gulpfile.js file:
browserSync.init({
port: 80,
notify: false,
cors: true,
browser: 'chrome',
open: 'local'
});
gulp.task('watch', ['browserSync'], function (){
gulp.watch('dev/*.html', browserSync.reload);
gulp.watch('dev/**/*.js', browserSync.reload);
gulp.watch('dev/**/*.css', browserSync.reload);
});
gulp.task('default', function(callback) {
var sequence = ['browserSync'];
if (args.sync){
sequence.push('watch')
}
runSequence(sequence,callback);
});
This if (args.sync) lines use truthy/falsy searching for sync values and enable/disable 'watch' task.
BrowserSync with watch:
gulp --sync true
BrowserSync without watch:
gulp or gulp --sync false

GULP - How to use gulp in production /deployment?

I have not much experience with gulp and wonder what to do when deploying? How do I exclude certain tasks (like my 'sass' task for example) when deploying or how does gulp work for production - what would I do? I'm not sure if I use the wrong words or just don't understand it, but I couldn't find much online so far.
My gulp file:
var gulp = require('gulp');
var sass = require('gulp-sass');
var browserSync = require('browser-sync').create();
var cleanCSS = require('gulp-clean-css');
var rename = require("gulp-rename");
var uglify = require('gulp-uglify');
// Compiles SCSS files from /scss into /css
gulp.task('sass', function() {
return gulp.src('scss/main.scss')
.pipe(sass())
.pipe(gulp.dest('css'))
.pipe(browserSync.reload({
stream: true
}))
});
// Minify compiled CSS
gulp.task('minify-css', ['sass'], function() {
return gulp.src('css/main.css')
.pipe(cleanCSS({
compatibility: 'ie8'
}))
.pipe(rename({
suffix: '.min'
}))
.pipe(gulp.dest('css'))
.pipe(browserSync.reload({
stream: true
}))
});
// Minify custom JS
gulp.task('minify-js', function() {
return gulp.src('js/scripts.js')
.pipe(uglify())
.pipe(rename({
suffix: '.min'
}))
.pipe(gulp.dest('js'))
.pipe(browserSync.reload({
stream: true
}))
});
// Copy vendor files from /node_modules into /vendor
// NOTE: requires `npm install` before running!
gulp.task('copy', function() {
gulp.src([
'node_modules/bootstrap/dist/**/*',
'!**/npm.js',
'!**/bootstrap-theme.*',
'!**/*.map'
])
.pipe(gulp.dest('vendor/bootstrap'))
gulp.src(['node_modules/jquery/dist/jquery.js',
'node_modules/jquery/dist/jquery.min.js'])
.pipe(gulp.dest('vendor/jquery'))
gulp.src(['node_modules/jquery-easing/*.js'])
.pipe(gulp.dest('vendor/jquery-easing'))
})
// Default task
gulp.task('default', ['sass', 'minify-css', 'minify-js', 'copy']);
// Configure the browserSync task
gulp.task('browserSync', function() {
browserSync.init({
server: {
baseDir: ''
},
})
})
// Dev task with browserSync
gulp.task('dev', ['browserSync', 'sass', 'minify-css', 'minify-js'], function() {
gulp.watch('scss/*.scss', ['sass']);
gulp.watch('css/*.css', ['minify-css']);
gulp.watch('js/*.js', ['minify-js']);
// Reloads the browser whenever HTML or JS files change
gulp.watch('*.html', browserSync.reload);
gulp.watch('js/**/*.js', browserSync.reload);
});
It depends entirely on your hosting solution and what deployment process you prefer to use. Some of your former questions have the Heroku tag so I assume you use Heroku. If not you can use the second strategy.
One method of using Gulp with Heroku is to automatically run Gulp when you push to the Heroku branch. This is done by having a postinstall script in package.json. Like so:
"scripts": {
..
"postinstall": "gulp"
}
When you push to the remote branch, Heroku will run the build process as normal. After the build process is done it will run the postinstall script. That will run the default task in the gulpfile. This will, of course, run on your Heroku dyno, not on localhost.
If you want to change the different sub tasks that are run during postinstall you can make a new task like this:
gulp.task('deployment', ['minify-css', 'minify-js', 'copy']);
and change the postinstall script to this:
"postinstall": "gulp deployment"
The deployment task will now run instead of the default task.
For this to work you need all the gulp packages in dependencies rather than devDependencies. devDependencies are, after all, not installed on Heroku.
The files that Gulp builds should be added to the .gitignore file. The files that Gulp outputs are often sent to a folder called dist which is kept out of the repository completely. You don't need to have them in the repository as they are being built on Heroku instead.
Another method is to build the files manually yourself before deployment. That means you don't have gulp in the postinstall script (or don't have the postinstall script at all) and keep the gulp packages in devDependencies. The files that are being built should also not be in .gitignore.
Before you deploy you build the files with gulp deployment and then commit them. When you push to Heroku the files will be uploaded like normal, instead of being built there.
This strategy is usually used when you have an ordinary web hosting service.

Gulp-sass and browser-sync don't reload browser

When I change some scss file everything seems to work (scss is compiled to css file and the source files are watched):
[21:19:46] Starting 'sass'...
[BS] 1 file changed (principal.css)
[21:19:46] Finished 'sass' after 18 ms
But I need to reload the browser by hand to reflect the changes. This is my gulpfile:
var gulp = require('gulp');
var browserSync = require('browser-sync').create();
var sass = require('gulp-sass');
// Static Server + watching scss/html files
gulp.task('default', ['sass'], function() {
browserSync.init({
proxy: "huertajalon/"
});
gulp.watch("./sass/**/*.scss", ['sass']);
gulp.watch("./*.php").on('change', browserSync.reload);
gulp.watch("./style.css").on('change', browserSync.reload);
});
// Compile sass into CSS & auto-inject into browsers
gulp.task('sass', function() {
return gulp.src("sass/principal.scss")
.pipe(sass())
.pipe(gulp.dest("./css"))
.pipe(browserSync.stream());
});
In other cases (for example, when I modify and save style.css) the browser reloads well.
What am I doing wrong? Thanks!
Are you using browser-sync version 2.6.0 or higher, since this is required to use browserSync.stream().
http://www.browsersync.io/docs/api/#api-stream
If not then you should update or you could try browserSync.reload({stream: true}) instead, which was the previous way to handle streams with browser-sync. If I remember correctly.
Try something like this.
gulp.task(default, ['sass'], browserSync.reload);
Also refer to http://www.browsersync.io/docs/gulp/#gulp-reload

Gulp not watching correctly

I'm new to using gulp and I think I have it setup correctly, but it does not seem to be doing what it should be doing.
My gulpfile.js has
gulp.task('compass', function() {
return gulp.src('sites/default/themes/lsl_theme/sass/**/*.scss')
.pipe(compass({
config_file: 'sites/default/themes/lsl_theme/config.rb',
css: 'css',
sass: 'scss'
}))
.pipe(gulp.dest('./sites/default/themes/lsl_theme/css'))
.pipe(notify({
message: 'Compass task complete.'
}))
.pipe(livereload());
});
with
gulp.task('scripts', function() {
return gulp.src([
'sites/default/themes/lsl_theme/js/**/*.js'
])
.pipe(plumber())
.pipe(concat('lsl.js'))
.pipe(gulp.dest('sites/default/themes/lsl_theme/js'))
// .pipe(stripDebug())
.pipe(uglify('lsl.js'))
.pipe(rename('lsl.min.js'))
.pipe(gulp.dest('sites/default/themes/lsl_theme/js'))
.pipe(sourcemaps.write())
.pipe(notify({
message: 'Scripts task complete.'
}))
.pipe(filesize())
.pipe(livereload());
});
and the watch function
gulp.task('watch', function() {
livereload.listen();
gulp.watch('./sites/default/themes/lsl_theme/js/**/*.js', ['scripts']);
gulp.watch('./sites/default/themes/lsl_theme/sass/**/*.scss', ['compass']);
});
when I run gulp, the result is
[16:14:36] Starting 'compass'...
[16:14:36] Starting 'scripts'...
[16:14:36] Starting 'watch'...
[16:14:37] Finished 'watch' after 89 ms
and no changes are registered.
for file structure, my gulpfile.js is in the root directory and the sass, css, and js are all in root/sites/default/themes/lsl_theme with the sass folder containing the folder 'components' full of partials.
My assumption is that you are on windows? Correct me if I'm wrong.
There is this problem that gulp-notify tends to break the gulp.watch functions. Try commenting out
// .pipe(notify({
// message: 'Scripts task complete.'
// }))
and see if the problem still exists.
If that does fix the issue, a solution from this thread may be helpful.
You can use the gulp-if
plugin in combination with
the os node module
to determine if you are on Windows, then exclude gulp-notify, like
so:
var _if = require('gulp-if');
//...
// From https://stackoverflow.com/questions/8683895/variable-to-detect-operating-system-in-node-scripts
var isWindows = /^win/.test(require('os').platform());
//...
// use like so:
.pipe(_if(!isWindows, notify('Coffeescript compile successful')))
It turns out that a large part of my issue was just simply being a rookie with Gulp. When I removed 'scripts' from my gulp watch it started working.
I then made the connection that it was watching the same directory that it was placing the new concatenated and minified js files in so it was putting the new file, checking that file, and looping over and over causing memory issues as well as not allowing 'compass' to run.
After creating a 'dest' folder to hold the new js everything started working just peachy.

Running 'gulp-preprocess' as part of 'gulp serve' task

I am basing my project off Google Web Starter Kit and am looking to integrate gulp-preprocess into the gulp pipeline.
I have managed to get it to work for the gulp serve:dist task, the relevant code is:
gulp.task('htmlIncludes', function() {
gulp.src('app/*.html')
.pipe(preprocess({context: { NODE_ENV: 'production', DEBUG: true}}))
.pipe(gulp.dest('./dist/'))
});
gulp.task('default', ['clean'], function (cb) {
runSequence('styles', ['jshint', 'html', 'images', 'fonts', 'copy', 'htmlIncludes'], cb);
});
However, I am having trouble getting it to work for the gulp:serve task which includes browser sync:
gulp.task('serve', ['styles'], function () {
browserSync({
notify: false,
server: ['.tmp', 'app']
});
I would like to add the htmlIncludes task, so that it is re-run when files are updated while running gulp:serve. However, simply adding it to the list which currently includes 'styles' does not have the desired effect. Any idea what I need to change?
You are totally right, you have to add it to the dependencies of this task to be run at least once. However, this is just half of the story. You have to run your task each time your HTML files have changed, so add it to the respective watch process:
gulp.task('serve', ['styles', 'htmlIncludes'], function () {
browserSync({
notify: false,
logPrefix: 'WSK',
server: ['.tmp', 'app']
});
// here's the change
gulp.watch(['.tmp/**/*.html', 'app/**/*.html'], ['htmlIncludes', reload]);
gulp.watch(['app/styles/**/**/**/**/*.{scss,css}'], ['styles', reload]);
gulp.watch(['app/scripts/**/*.js'], ['jshint']);
gulp.watch(['app/images/**/*'], reload);
});
You also see that this browserSync call just serves .tmp and app folders, while your output is stored in dist. So you have to change your htmlIncludes task, too:
gulp.task('htmlIncludes', function() {
return gulp.src('app/*.html')
.pipe(preprocess({context: { NODE_ENV: 'production', DEBUG: true}}))
.pipe(gulp.dest('./.tmp/'))
.pipe(gulp.dest('./dist/'))
});
If you need separate configurations for each output, we have to tackle it again. But for now it should work as planned.
It also might be possible that you have to run the 'html' task in sequence first, but I'm not that fit in the WSK Gulpfile to answer you that ;-)

Gulp "watch" is not running the sub task "sass" on file change

I am using Gulp for watch and sass complier. When I start "watch" first time then "sass" complier runs and its create the css files as per given path. However when I change the .scss files then it doesn't call "sass" complier again. Following is is my these two tasks and variables.
gulp.task('sass', function () {
gulp.src(config.sassPath)
.pipe(sass())
.pipe(gulp.dest(config.cssPath))
.pipe(livereload());
});
gulp.task('watch', false, function () {
livereload.listen(8189);
gulp.src(config.watchPaths)
.pipe(watch(config.watchPaths, function (event) {
gulp.start( 'sass', 'js-hint', 'server','test');
livereload();
}))
.pipe(livereload());
});
Following command i use to run "watch" task
gulp watch
I do see "watch" is reloading when I am changing the .scss file. Following is log for this.
[19:49:30] public/sass/html-controls.scss was changed
[19:49:30] /Users/dkuma204/Desktop/Dilip/Projects/OPEN/SourceCode/AWF/OPENApp/application/public/sass/html-controls.scss reloaded.
Not sure what I am missing here. Please help.
Why it is so complicated? Try this:
gulp.task('watch', false, function () {
livereload.listen(8189);
gulp.watch(config.watchPaths,['sass', 'js-hint', 'server', 'test'])
});
And your every task which requires livereload should have .pipe(livereload()) at the end.
You shouldn't use gulp start. Here is one of comment from github discussion:
gulp.start is undocumented on purpose because it can lead to
complicated build files and we don't want people using it
