I am using webpack in my Project, here is the tools:
HTML as - jade-html-loader
CSS as - sass-loader
Project written with AngularJS - all with components & templateUrl (ngTemplate-loader in webpack)
So I got 1 JS file in the end of the process.
All this stuff pretty cool, but I think that it will be good to create static HTML files for clients...
It's going to Improve performance(caching / no need to draw DOM elements throw JS) and it's better for browser - to download few small files, not one big JS...
I am wrong? I can't find good tools that generates static assets(html, css)/cache files.
In the end of the line - I need to find an easy way to require Jade files as templates(templateUrl) into Angular Component, but files needs to be static - so I can see them in "Sources" of the browser...
It is hard to explain - so I hope you can understand me =(.
I been there and what i learned is angular cache template are faster then static. You can also copy static html files to dist map using npm cpy tool but i will highly recommend you to use angular cache template. There is this tool you can use for converting you jade to html.
You don't need to build only one single file you could build one for the vendors and one for your app this will keep your app more clean and you can also make one for the only templates which load in angular from cache on demand. I hope i could explain. webpack come with lot's awesome plugins witch can make life easier! good luck
After week I agree that cache templates works fantastic! =).
I used plugin "webpack.optimize.CommonsChunkPlugin" to generate 2 files for my app:
Vendor - all node_modules/bower_components/libs (js+css).
App - all source of app - controllers/models/business logic/views (js,css(sass),html(jade+ngTemplate for angular)).
My entry looks like:
entry: {
app: './src/app.js',
vendor: [
"angular",
"angular-route",
... and other libs...
],
},
And there I found really cool thing: html-webpack-plugin - this plugin creates index.html file and automatically attaches all your generated JS files.
Add Used "hash" string to my files.
My dist looks like this:
/dist
/index.html
/app.xxxxxxxxx.js
/vendor.xxxxxxxxxx.js
Little magic with webpack.optimize.UglifyJsPlugin to minify all files.
And now I got lightweight, small app that waiting for deploy! =)

We're attempting to create a PHP Laravel application using ReactJS as the view for each page. Laravel handles the routing and the presenting of each view. Each view loads a react js bundle.js file. Each bundle.js file is custom to that view and inside contains the react components needed for that view (screen). What were finding out is that each bundle.js file is about 4MB because each contain its dependencies as well as the components. Also were still trying to figure out how to share a component such as a TableComponent.js file across multiple views but have been so far unsuccessful.
Are we architecting this totally wrong? Should there always be only one bundle.js file for the application as a whole?
Or are there good fixes to remove the dependencies from each bundle.js file in a single dependency js file that gets loaded for all views?
Is there a good way to reuse ReactJS components accross multiple bundle.js files ?
Sounds like a perfect case to use Webpack which is an amazing bundling tool, here is an example on how to build multiple entries(pages):
https://webpack.github.io/docs/multiple-entry-points.html
You just write your entry point code, and webpack will figure out the details on how to build shared dependencies of different entries(pages) into a common bundle.
I'm trying to figure out the right way to add any eventual new library (for example I need angularJS ui-router) in an onsen app.
I installed bower and then downloaded ui-router.
Since I do not know exactly the way Gulp is used, I got confused on what I'm suppose to do.
At the moment, I have the following folders:
bower_components, hooks, merges, node, modules, platforms, plugins, www
The index.html has the following reference:
What I suppose to do, now?
manually copy the ui-router js files in /www/lib/
configure gulp to copy the files automatically
change the script tag src and make the reference to the bower_component folder
change the Bower default folder
could you please guide me on sort it out?
tnx
At the end I chose the option 2.
I edited the file gulpfile.js adding a new custom task supposed to copy the missing bower libraries.
var mainBowerFiles = require('main-bower-files');
gulp.task('copy-bower-libs', function() {
return gulp.src(mainBowerFiles())
.pipe(gulp.dest(__dirname + "/www/lib/bower/js"))
});
This is a must-answer question that needs answered for a generation of coders.
I know to go to the website, but how do you actually download Backbone and start coding.
Most tutorials leave out this stage.
Thanks for helping!
Most Backbone code I see on stackoverflow is a real mess lacking structure which is a shame. But the flexibility in the right hands is also a very strong point that is why larger companies still use frequently choose Backbone whilst newbies would go for something with a little more magic out the box like Angular or Ember.
This is what I recommend in a general sense:
Grunt or gulp for tasks - grunt might be easier as it is more widely used still. Main tasks would be:
- build (compile and minify your code and css) and bundle into a build folder
- server (runs local server or a server from a build folder)
- test (if you have unit or functional tests)
Next you have an index.html file which contains an app wrapper and a single RequireJS call the the entry point of your code.
My folder structure would look something like this:
server/
server/server.js
public/
public/app/app.js
public/app/modules/
public/app/extensions/
public/assets/
public/assets/css/
public/assets/images/
public/packages/
public/index.html
dist/
dist/<env>/public/assets/
dist/<env>/public/app/app.min.js (or app.js depending on env)
package.json
Gruntfile.js
A colleague's boilerplate is probably the closest to my ideal setup in the public domain: https://github.com/mderrick/backbone-boilerplate

We have an extjs application where the structure we laid out doesn't exactly match the structure Sencha recommends. In our structure we don't have an app.js but we do have a js where we mention the autoload and launch function, example as below along with the folder structure.
What we are looking is to minify all the JS files in admin folder and create one JS to be used in production, we tried looking at the Sencha CMD but of no luck. Can some one please point us for the exact steps for minifying our application for production use.
Ext.Loader.setConfig({
enabled: true,
paths: {
'Admin': '../../script/js/ace/admin',
'Ext.ux': '../../script/js/ext4/ux'
}
});
Ext.require('Admin.view.Administration');
Ext.application({
name: 'Admin',
appFolder: '../../script/js/ace/admin',
launch: function()
{
Ext.QuickTips.init();
var me = this;
Ext.create('Admin.view.Administration', {
renderTo: 'contentPanel'
});
}
});
We tried Cmd by generating JSB3 file, I know its deprecated in 4.2.1 but with the structure we have we felt that was the only option.
we tried the below command, but no jsb3 file got generated
sencha build admin.jsb3 <path to the admin js folder>
Thanks in advance, any pointers are really appreciated.
I posted this in Sencha forum, but I am expecting a much simpler option then they have provided.
Edit
we have multiple apps, and in most cases we try to use the js from other app folders.
For example in the below image we have utilities and admin apps, from utilities app we use SourceStore and the autoloader is defined as below to access the required
Ext.Loader.setConfig({
enabled: true,
paths: {
'Admin': '../../script/js/ace/admin',
'Utilities': '../../script/js/ace/utilities',
'Ext.ux': '../../script/js/ext4/ux'
}
});
If you let Sencha CMD to generate a skeleton application for you and then merge your existing code with it, then it will be really easy.
Otherwise you can try the old JSBuilder from Sencha as well.
I'd highly recommend checking out grunt with the grunt_sencha_dependencies plugin. Here's a tutorial.
At a high level, what you do is:
1) Run the sencha_dependencies plugin to generate a list of dependencies.
2) Pass the outputs to the uglify plugin to concat and minify the javascript.
3) Use grunt's copy task to replace to update your index.html with the minified output.
edit: I've dealt with Sencha CMD and it is awful. I would not wish it on my worst enemy. Grunt is just way easier.
I recommend you using JAWR. Basically you define in the jawr.properties file your bundles, and say which file or folder belongs to which bundle. A bundle is actually a bunch of JS files that are minified into another single one and can be requested separately in your servlets/JSP files. Besides, you can define dependencies between bundles (which by default are independent), so that when you include a bundle, other bundles are automatically included in your page. To include a bundle you use the special tag <jwr> in your servlet. Besides, you can enable the debug mode, so that when you develop, you can debug your code.
How it works: you add a servlet to your web.xml file to be loaded on start-up, which is also the stage when these bundles are generated (transparent to you).
Some tips:
Check this tutorial
Because in ExtJS the order in which the files are used is important, you should consider it when you define your bundles.
If you are willing to give Sencha CMD another shot, you could try using the sencha compile command.
sencha compile --classpath=folders-your-using,separated-by-commas concatenate --yui --output-file=output.js
--classpath is the folders you want to include.
--yui is the compressor
--output-file is the name of the javascript output.
I would recommend reading the sencha cmd guides. They can be a little intense, but sencha command packs so many tools in it that it probably deserves to be: http://docs.sencha.com/cmd/5.x/advanced_cmd/cmd_reference.html
Using gulpjs and bower, Id like to start with the bower.json file to call on what package dependencies I want (ideally start the build with html 5 boilerplate, then backbone). Since the whole point of using gulp is for easy project management I would like to understand how to auto insert the scripts in to my project (pulling from the bower_components dir) and add the path to my head tags, I assume this is a responsibility gulp should be handling, in the link below I am under the impression grunt does provide this functionality, so if grunt can gulp should be able to.
This tut seems to cover everything I am looking for, except it is using gruntjs with the plugin "grunt-bowercopy" http://simonsmith.io/managing-bower-components-with-grunt/
So does anyone know how to get gulp and bower to play nicely. It would be cool to download the html 5 boilerplate, then for my javascript include backbone/jquery as well as some css like fontawesome and such with one command bower update, and have it insert the script tags in my header, and pull the main files I need into my project (this would kill a lot of tedious work). I assume grunt does handle this specifically with the "grunt-bowercopy" plugin, so essentially I am looking for a plugin "gulp-bowercopy" or something that provides this?
I still have a lot to learn about gulp/grunt and how to really leverage them, but this seems like an awesome tool to have.

You should then consider looking into either:
gulp-bower
or gulp-bower-files
as they likely provide the same functionality as grunt-bowercopy.
You can just use wiredep directly like the gulp Yeoman generator does. Here's a code sample from the gulpfile.js.
var wiredep = require('wiredep').stream;
gulp.task('wiredep', function () {
gulp.src('app/styles/*.scss')
.pipe(wiredep({
directory: 'app/bower_components',
ignorePath: 'app/bower_components/'
}))
.pipe(gulp.dest('app/styles'));
gulp.src('app/*.html')
.pipe(wiredep({
directory: 'app/bower_components',
ignorePath: 'app/'
}))
.pipe(gulp.dest('app'));
});
