I'm trying to follow along with a wordpress guide on Lynda.com that instructs me to use npm and Browser-Sync. Everything was working properly when I was working on a windows machine but I have recently setup a linux server (Ubuntu 16.04) and cannot seem to access the External URL Browser-Sync gives me. I am on the same network, and it does not work on any of my devices. I have the site setup to http://custom.local. Below is the Gulpfile.js I am using to initiate browser-sync.
var themename = 'custom';
var gulp = require('gulp'),
// Prepare and optimize code etc
autoprefixer = require('autoprefixer'),
browserSync = require('browser-sync').create(),
image = require('gulp-image'),
jshint = require('gulp-jshint'),
postcss = require('gulp-postcss'),
sass = require('gulp-sass'),
sourcemaps = require('gulp-sourcemaps'),
// Only work with new or updated files
newer = require('gulp-newer'),
// Name of working theme folder
root = '../' + themename + '/',
scss = root + 'sass/',
js = root + 'js/',
img = root + 'images/',
languages = root + 'languages/';
// CSS via Sass and Autoprefixer
gulp.task('css', function() {
return gulp.src(scss + '{style.scss,rtl.scss}')
.pipe(sourcemaps.init())
.pipe(sass({
outputStyle: 'expanded',
indentType: 'tab',
indentWidth: '1'
}).on('error', sass.logError))
.pipe(postcss([
autoprefixer('last 2 versions', '> 1%')
]))
.pipe(sourcemaps.write(scss + 'maps'))
.pipe(gulp.dest(root));
});
// Optimize images through gulp-image
gulp.task('images', function() {
return gulp.src(img + 'RAW/**/*.{jpg,JPG,png}')
.pipe(newer(img))
.pipe(image())
.pipe(gulp.dest(img));
});
// JavaScript
gulp.task('javascript', function() {
return gulp.src([js + '*.js'])
.pipe(jshint())
.pipe(jshint.reporter('default'))
.pipe(gulp.dest(js));
});
// Watch everything
gulp.task('watch', function() {
gulp.task('watch', function() {
browserSync.init({
open: false,
proxy: 'custom.local',
port: 8080
});
gulp.watch([root + '**/*.css', root + '**/*.scss' ], ['css']);
gulp.watch(js + '**/*.js', ['javascript']);
gulp.watch(img + 'RAW/**/*.{jpg,JPG,png}', ['images']);
gulp.watch(root + '**/*').on('change', browserSync.reload);
});
// Default task (runs at initiation: gulp --verbose)
gulp.task('default', ['watch']);
I've tried using different ports, and setting tunnel: true, and anything else I can find, but I'm getting a whole lot of nothing. Any assistance would be amazing.
Thank you,
If you come across this and are having a similar issue, I just fixed it. I am using a headless environment so I didn't think to set up an entry in the hosts file.

I've been trying to get this straight for a few days now but haven't been able to get it working the way I need to. I'm unable to find any examples of other people using Browsersync with .net core, that may even be the reason I'm experiencing all of these issues. But I can't find any evidence that proves that and wouldn't understand why exactly that would be the case.
Anyway... I've got everything working in my gulp file exactly how I want it to for sass/js for handling errors, etc. I'm not new to gulp otherwise I'd blame my lack of experience for my inability to get this working.
Here's my gulp file followed by what the output is when running gulp.
Default Task:
const gulp = require("gulp"),
uglify = require("gulp-uglify"),
sass = require("gulp-sass"),
rename = require('gulp-rename'),
sassGlob = require('gulp-sass-glob'),
postcss = require('gulp-postcss'),
autoprefixer = require('gulp-autoprefixer'),
sourcemaps = require('gulp-sourcemaps'),
cleanCSS = require('gulp-clean-css'),
concat = require('gulp-concat'),
msbuild = require('gulp-msbuild'),
through = require('through2'),
notifier = require('node-notifier'),
browserSync = require('browser-sync').create();
// Static Server + watching scss/html files
gulp.task('serve', ['sass', 'compileJS'], function() {
browserSync.init({
proxy : {
target: "https://localhost:3000",
},
files: ['./wwwroot/css/*'],
rewriteRules: [
{
match: new RegExp('/css/main.min.css'),
fn: function() {
return './wwwroot/css/main.min.css'
}
}
]
});
//Watch for any changes to the scss files.
gulp.watch('./wwwroot/sass/**/*.scss', ['sass']);
//Watch for any changes to the js files, reload after those changes are made.
gulp.watch('./wwwroot/js/source/*.js', ['compileJS']).on('change', browserSync.reload);
//Watch for any changes to a .cshtml file and reload the browser if/when that change happens.
gulp.watch("./**/*.cshtml").on('change', browserSync.reload);
});
gulp.task('default', ['serve']);

console.log('Sass Error:', err.toString());
notifier.notify({

});
this.emit("end");

})
)
.pipe(

cb(null, chunk)
})
)
.pipe(cleanCSS({compatibility: 'ie8',

.pipe(rename({suffix: '.min'}))
.pipe(gulp.dest('./wwwroot/css'))
.pipe(browserSync.stream());
});
/**

gulp.task('compileJS', function (done) {
return gulp.src('./wwwroot/js/source/*.js')
.pipe(sourcemaps.init())
.pipe(concat('main.js'))
.pipe(uglify().on('error', function (err) {
console.log('JS Uglify Error:', err.toString());
notifier.notify({

});
this.emit("end");
}))
.pipe(rename({suffix: '.min'}))
.pipe(sourcemaps.write('../maps'))
.pipe(gulp.dest('./wwwroot/js/dist'));
});
Output:

[Browsersync] Reloading Browsers...
So, looking at that output you would probably think to yourself, "This dude is an idiot... Browsersync states that it's reloading browsers..." Right, it does state that, but it is not reloading the browser. Browsersync also fails to inject my css into the browser as well.
As I mentioned, I've used gulp before, and this setup closely represents the gulp files that I use when doing Wordpress development as well. However, it won't work for this project (which has led me to my .net core / Visual Studio suspicions).
You could just do something like this
Create a env variable thats global to your application then above the closing tag in your view you can add the following code.
This code is how I do it in Laravel with my Blade templates but it should be exactly the same you just need to replace it with the way .NET does it, I think they use Razor templating engine :)
{{-- Live reload with browser sync --}}
#if (!empty(env('APP_ENV')) && env('APP_ENV') === 'local')
<script
async
defer
src="{{ URL::to('/') . ':3000/browser-sync/browser-sync-client.js?v=2.26.7'}}">
</script>
#endif
Hope this helps you.
Just for interest sake below is my gulp pipeline:
const browserSync = require("browser-sync");
const sass = require("gulp-sass");
const autoprefixer = require("gulp-autoprefixer");
const sourcemaps = require("gulp-sourcemaps");
const rename = require("gulp-rename");
const reviser = require("gulp-rev");
const runSequence = require("run-sequence");
gulp.task("browserSync", function() {
return browserSync.init({
open: false,
https: false,
notify: false,
injectChanges: true,
proxy: "http://{site-name-here}.local/",
});
});
gulp.task("compile:scss", function() {
return (
gulp
// Gets the main.scss file
.src("resources/assets/scss/main.scss")
// Passes it through a gulp-sass, log errors to console
.pipe(sass().on("error", sass.logError))
// Adds versioning
.pipe(reviser())
// Add vendor prefixes
.pipe(
autoprefixer({
browsers: ["last 2 versions"],
cascade: false
})
)
// Rename the file
.pipe(rename({ suffix: ".min" }))
// Outputs it in the css folder
.pipe(gulp.dest("public/css"))
// Add sourcemaps
.pipe(sourcemaps.write())
// Adds versioned file to manifest so we can access with the same name
.pipe(reviser.manifest("manifest/rev-manifest.json"), { merge: true })
// Outputs it in the css folder
.pipe(gulp.dest("public/css"))
.pipe(
browserSync.reload({
// Reloading with Browser Sync
stream: true
})
)
);
});
// Watchers
gulp.task("watch", function() {
gulp.watch(["./resources/assets/scss/**/*"], "compile:scss", browserSync.reload);
});
// Default task
gulp.task("start", function(callback) {
return runSequence(
"browserSync",
"compile:scss",
"watch",
callback
);
});
to use it I just run gulp start
Keep in mind that running gulp like this you will need to have gulp installed globally. to do this run npm install --global gulp-cli

I recently picked this project back up after a month long break and haven't touched the code since, yet I've never had this issue before.
I have this problem when I try to run 'gulp rundev' in my Git Bash window. It appears to complete without errors but never actually serves the files and I can't use the Git Bash window or even close it afterwards (none of these work: clicking exit, Alt+F4, or killing the process in Task Manager). The only way to get rid of it is to restart the computer. I'm using Windows 10, Node v8.9.4, Gulp v3.9.1, Brackets, and Git Bash as my development environment in case that helps.
Here's a copy of the output:

[Browsersync] Serving files from: dist
I do remember getting more 'Starting' and 'Finished' lines in the output for the other tasks that are called by 'rundev' but otherwise the output looks normal.
Since the 'clean' task never reports as 'Finished' I assume the problem is somehow related to that and my research seems to indicate that the problem has something to do with permissions or the files being locked when it tries to operate on them. To this end, I've tried messing with the devMode, closing all programs except the Git Bash to call the task, and making sure everything is running with admin privileges, but it always hangs.
I'm a bit new to Node and Gulp so there may be something glaringly obvious that I don't even know to ask about, so hopefully someone here can help me learn my way through this.
it seems there is something im missing - Im just trying to get the css injection working on this project.
The server proxy works
The file watcher too
The injection works,
but the page always reloads half a second after...
Im on Mac osx 10.11.6 (15G1108)
Node v4.1.1
here is my gulpfile:
var gulp = require('gulp');
var browserSync = require('browser-sync').create();
var reload = browserSync.reload;
var sass = require('gulp-sass');
var plumber = require('gulp-plumber');
var notify = require("gulp-notify");
var src = {
scss: 'assets/scss/**',
css: 'assets/css/',
html: 'app/*.html'
};
gulp.task('serve', ['sass'], function() {
browserSync.init({
proxy: "intouch.local",
open: false,
reloadOnRestart: false,
injectChanges: true,
});
gulp.watch(src.scss, ['sass']);
});
gulp.task('sass', function() {
var onError = function(err) {
notify.onError({
title: "Gulp",
subtitle: "Failure!",
message: "Error: <%= error.message %>",
sound: "Beep"
})(err);
this.emit('end');
};
return gulp.src(src.scss)
.pipe(plumber({errorHandler: onError}))
.pipe(sass())
.pipe(gulp.dest(src.css))
// NOTE: i've tried with all of these lines, all do the same...
// .pipe(reload({stream: true}))
// .pipe(browserSync.stream())
.pipe(browserSync.reload({
stream: true
}))
.pipe(notify({
title: 'Gulp',
subtitle: 'success',
message: 'Sass task',
sound: "Pop"
}));
});
gulp.task('default', ['serve']);
Adjust the glob for the sass files you want to compile to only match .scss (or .sass) files:
e.g. in your code example change assets/scss/** to assets/scss/**/*.scss.
A broad glob can result in unexpected files (typically source maps) being passed down the pipeline and Browsersync's default behaviour when it encounters modified files that can't be streamed is to reload the page, hence you get a successful injection for the CSS and then a hard reload for some files you probably didn't expect / don't care about.
I am currently trying to write a gulp task that allows me to serve development code up through a node webserver and use browser sync to reload the page. In doing so i'm attempting to use the events with nodemon, so for example when start event occurs, I want my gulp to log what its starting. Currently the events for gulp nodemon are not firing at all. No error is being thrown and the web server is starting. I'm not sure what I am doing wrong.
gulp.task('serve-dev', ['inject'], function(){
var isDev = true;
var nodeOptions = {
script: config.nodeServer,
delayTime: 1,
env: {
'PORT': port,
'NODE_ENV': isDev ? 'dev': 'build'
},
watch: ['server.js']
};
$.nodemon(nodeOptions)
.on('start', function(){
log('*** nodemon started');
// startBroswerSync();
})
.on('restart', function (ev){
log('*** nodemon restarted');
log('files changed on restart:\n' + ev);
})
.on('crash', function(){
log('Server Crashed for some reason');
})
.on('exit', function(){
log('Server Ended Cleanly');
})
Here is my config File:
module.exports = function() {
var client = './src/';
var temp = './.tmp/';
var server = './server.js';
var config = {
// Location of index.html
index: client + 'index.html',
// Temp folder
temp: temp,
// All of the js files to load
js: [
client + '**/*.module.js',
client + '**/*.js',
'!' + client + '**/*.spec.js'
],
// Root Folder of App(Where to find index.html etc...)
client: client,
// Where to find build Sass and CSS files
css: [temp + '*css', client + 'css/*.css'],
// All Js to Vet
alljs: [
'./src/**/*.js',
'./*js'
],
// Path to Node Server
server: server,
//Sass to Compile
sass: ['src/scss/*.scss'],
// Bower and NPM Locations
bower: {
json: require('./bower.json'),
directory: './bower_components/',
ignorePath: '../..'
},
// Node Settings
defaultPort: 7203,
nodeServer: './server.js'
};
config.getWiredepDefaultOptions = function() {
var options = {
bowerJson: config.bower.json,
directory: config.bower.directory,
ignorePath: config.bower.ignorePath
};
return options;
};
return config;
};
Completely Unrelated answer, log method was not functioning properly, thus no log statements....sorry

My system is Windows 7, nodejs version is v0.10.32, gulp version:

Also, the same error I am getting on Ubuntu 12.04 LTS while on newer Ubuntu (not sure what version) and mac os it is seems to be working ok. What can cause this error?
Update 5/11/2016: Before writing comment about the fact that accepted answer hide errors, please, see first two comments to that particular accepted answer. Use it only if know what you are doing. Related info: https://github.com/karma-runner/gulp-karma/pull/15
How are you running your tests with Gulp? I came up against this issue recently on OSX, running node v0.11.14 and gulp 3.8.10, whenever there were failing tests.
Changing from the recommended:
gulp.task('test', function(done) {
karma.start({
configFile: __dirname + '/karma.conf.js',
singleRun: true
}, done);
});
To:
gulp.task('test', function(done) {
karma.start({
configFile: __dirname + '/karma.conf.js',
singleRun: true
}, function() {
done();
});
});
...got rid of this error.
Seems to be down to how gulp handles error messages when an error is signalled in a callback. See Improve error messages on exit for more information.
None of these solutions worked correctly for me using gulp 3.9.1 and karma 1.1.1. Adding a reference to gulp-util npm install --save-dev gulp-util and updating the task to the below fix the error output very nicely, while maintaining exit status correctly.
var gutil = require('gulp-util');
gulp.task('test', function (done) {
new Server({
configFile: __dirname + '/karma.conf.js',
singleRun: true
}, function(err){
if(err === 0){
done();
} else {
done(new gutil.PluginError('karma', {
message: 'Karma Tests failed'
}));
}
}).start();
});
Below is a code snippet from gulp patterns on using Karma. It's a bit similar, but also uses the newer method how to start the karma.
/**
* Start the tests using karma.
* #param {boolean} singleRun - True means run once and end (CI), or keep running (dev)
* #param {Function} done - Callback to fire when karma is done
* #return {undefined}
*/
function startTests(singleRun, done) {
var child;
var excludeFiles = [];
var fork = require('child_process').fork;
var KarmaServer = require('karma').Server;
var serverSpecs = config.serverIntegrationSpecs;
if (args.startServers) {
log('Starting servers');
var savedEnv = process.env;
savedEnv.NODE_ENV = 'dev';
savedEnv.PORT = 8888;
child = fork(config.nodeServer);
} else {
if (serverSpecs && serverSpecs.length) {
excludeFiles = serverSpecs;
}
}
var server = new KarmaServer({
configFile: __dirname + '/karma.conf.js',
exclude: excludeFiles,
singleRun: singleRun
}, karmaCompleted);
server.start();
////////////////
function karmaCompleted(karmaResult) {
log('Karma completed');
if (child) {
log('shutting down the child process');
child.kill();
}
if (karmaResult === 1) {
done('karma: tests failed with code ' + karmaResult);
} else {
done();
}
}
}
What worked for me and gave a nice formatted error message is to provide an Error instance to the done callback.
gulp.task('test', function(done) {
karma.start({
configFile: __dirname + '/karma.conf.js',
singleRun: true
}, function(result) {
if (result > 0) {
return done(new Error(`Karma exited with status code ${result}`));
}
done();
});
});
If you want to return with an error code, and want to see Karma's error output but not Gulp's (probably unrelated) stack trace:
gulp.task('test', function() {
karma.start({
configFile: __dirname + '/karma.conf.js',
singleRun: true
}, function(karmaExitStatus) {
if (karmaExitStatus) {
process.exit(1);
}
});
});
Not sure about Ubuntu, but I was getting a similar error on Windows, and installing one version back fixed it right away like this:
npm install -g gulp#3.8.8
npm install gulp#3.8.8
this is gulp's way of telling your tests have failed and that karma exited with a return code of 1. Why you would want to call done yourself and not pass the error as a message baffles me.
The right way to solve this according to Karma's documentation and https://github.com/pkozlowski-opensource, is to rely on Karma's watch mechanism rather than Gulp's:
gulp.task('tdd', function (done) {
karma.start({
configFile: __dirname + '/karma.conf.js'
}, done);
});
Note the omission of singleRun: true.
#McDamon's workaround will work for gulp.watch, but you don't want to swallow exit codes like that when running on a CI server.
Gulp is also reworking how they handle exit codes in scenarios just like this one. See https://github.com/gulpjs/gulp/issues/71 and the other dozen or so related issues.
gulp.task('test', function(done) {
karma.start({
configFile: __dirname + '/karma.conf.js',
singleRun: false
}, done);
});
passing singleRun: false argument will prevent the process from returning a value different of 0 (which would signify an error and exit gulp).
Run with singleRun: true if you only launching your test from a command line, not part of a continuous integration suite.
In case anyone else comes here, do not use the accepted solution. It will hide failed tests. If you need a quick solution to modify your gulp test task, you can use the solution found in this comment in this github thread.
gulp.src(src)
// pipeline...
.on('error', function (error) {
console.error('' + error);
});
