How to organise controllers in Angular Js? - angularjs

I am trying to learn Angular js I am following angular-phonecat tutorial . I am trying to organize my controllers inside my controllers folder for that I am using this structure :
app/js
js/controllers/
Ctrl1.js
movies.js
Here everything is working fine but there is an issue suppose I have 100 controllers then how can I use them inside my html files which is like this :
<!doctype html>
<html lang="en" ng-app="phonecatApp">
<head>
<meta charset="utf-8">
<title>My HTML File</title>
<link rel="stylesheet" href="bower_components/bootstrap/dist/css/bootstrap.css">
<link rel="stylesheet" href="css/app.css">
<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/angular-route/angular-route.js"></script>
<script src="js/app.js"></script>
<script src="js/controllers.js"></script>
<script src="js/controllers/movies.js"></script>
<script src="js/controllers/Ctrl1.js"></script>
</head>
<body>
<div ng-view></div>
</body>
</html>
Is there any way by which I can reduce the calling of scripts in this line below how can I put this in one call where these two files can be called via one or there is any other efficient way :
<script src="js/controllers/movies.js"></script>
<script src="js/controllers/Ctrl1.js"></script>

Have a look at gulp. Gulp allows you to bundle all related files into one file which you can refer to in the index.html. For example, in my gulpfile I do this for all my JS files:
gulp.task('js', function() {
return gulp.src('./src/js/**/*.js').pipe(concat('main.js').on('error', gutil.log))
.pipe(gulp.dest('dist/js').on('error', gutil.log))
});
This places them all into a single file called main.js inside a dist folder which I can then deploy.
Oh - and we can then refer to this file in the index like so:
%body.container-fluid
%ui-view
%script{ src: "js/main.js", async: true }
Note - This is HAML syntax not pure HTML. Also - please bear in mind that gulp is made it by different plugins designed to do different things - each of which will need to be installed:
var uglify = require('gulp-uglify'),
// Allows me to use it in the gulpfile as uglify.foo()

I found a better solution to this problem. Simply go through this tutorial :http://yeoman.io/codelab/install-generators.html And you will get to know how to install yoman, here they are using grunt here it will generate all the hard work for you .
you simply need to run this command :
grunt build
grunt serve:dist
It will create a full minified js and css inside a dist directory and you can do whatever you want to do with that directory . You can also watch a this video :https://www.youtube.com/watch?v=gKiaLSJW5xI . I hope this way you can organise your files better .

Download UNPKG React zip

I could create a react app like this simply and it worked.
index.html:
<html>
<body>
<div id="root"></div>
<script src="https://unpkg.com/react#16.13.1/umd/react.development.js"></script>
<script src="https://unpkg.com/react-dom#16.13.1/umd/react-dom.development.js"></script>
<script src="https://unpkg.com/#babel/standalone#7.8.3/babel.js"></script>
<script type="text/babel">
ReactDOM.render(<div>Hello World</div>, document.getElementById('root'))
</script>
</body>
</html>
But, because i can't code online all the time. i wanna download those files with their root file with .zip. Where can i download them? Why i`m unsure just to download that links itself because i think they may have other dependencies too.
Thanks!
Unpkg is a global content delivery network for everything on npm, you can just copy and paste their links into your script tags.
Though if you want to have all your files locally, you can use npm for it.

Eliminate render-blocking JavaScript and CSS in above-the-fold content (Angular JS Controllers)

I am trying to optimize my page speed with me MEAN stack application. I have run into the issue where I should be eliminating the render-blocking Javascript and CSS. I have gotten to the point where I have almost eliminated everything, EXCEPT for the controllers that have to be loaded.
I am thinking that it is not possible to actually do this, since angular throws an injector module error when I place "async" as an attribute on the <script>.
I was also thinking of making one large controller, but that does not really work as well.
The link to the site is https://coastalreign.com, below is the code for the controllers:
<!-- ANGULAR CUSTOM -->
<script src="js/app.js"></script>
<script src="js/controllers/MainCtrl.js"></script>
<script src="js/controllers/ContactCtrl.js"></script>
<script src="js/controllers/ProductCtrl.js"></script>
<script src="js/controllers/ProductsCtrl.js"></script>
<script src="js/controllers/CartCtrl.js"></script>
<script src="js/controllers/TrackOrderCtrl.js"></script>
<script src="js/controllers/CheckoutCtrl.js"></script>
<script src="js/controllers/DesignerCtrl.js"></script>
<script src="js/controllers/SublimationCtrl.js"></script>
<script src="js/controllers/LocationCtrl.js"></script>
<script src="js/controllers/ServiceAreaCtrl.js"></script>
<script src="js/controllers/CategoriesCtrl.js"></script>
<script src="js/services/getCategoryText.js"></script>
<script src="js/controllers/CustomQuoteCtrl.js"></script>
<script src="js/controllers/GradContestCtrl.js"></script>
<script src="js/controllers/four04Ctrl.js"></script>
<script src="js/controllers/popularGroupingCtrl.js"></script>
Thank you in advance for your guy's expertise!
The problem is the amount of requests. I would bundle the JS files (app + vendor files) and minify them.
You can check for performance tips with Chrome - Developer tools - audits
You can use gulp-concat to reduce the amount of requests as Alexander's answer suggested. Then you can use gulp-minify to decrease the size of the file. You will have some additional issues if you want to put async option because you might need to render HTML which depends on angular

How to load Angular UI Bootstrap and dependencies

I'm experimenting with the Angular UI Bootstrap libraries (specifically modal) but I'm having trouble getting the right versions of each library loaded in the right order, but I keep coming up against the No module: template/accordion/accordion-group.html error. I've switched back to Bootstrap 2.3 but it's still there. My application header is below, can anyone spot any wrong versions or JS files out of order? I'm also using Angular UI Sortable, hence its inclusion.
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/2.3.2/js/bootstrap.min.js"></script>
<script src="http://code.angularjs.org/1.0.2/angular.min.js"></script>
<script src="http://cdnjs.cloudflare.com/ajax/libs/angular-ui/0.4.0/angular-ui.min.js"></script>

<link rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/themes/smoothness/jquery-ui.css">
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/2.3.2/css/bootstrap.css">
<link rel="stylesheet" href="style.css" />
</head>
My app declaration looks like this:
var app = angular.module('myModule', ['ui', 'ui.bootstrap']);
Edit
I managed to get it working like this:
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>

<script src="http://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/0.11.2/ui-bootstrap-tpls.min.js"></script>
<script src="http://cdnjs.cloudflare.com/ajax/libs/angular-ui-sortable/0.13.2/sortable.min.js"></script>

</head>
and
var app = angular.module('myModule', ['ui.sortable', 'ui.bootstrap']);
did you download all the files? according to their docs
Files to download
Build files for all directives are distributed in several flavours:
minified for production usage, un-minified for development, with or
without templates. All the options are described and can be downloaded
from here. It should be noted that the -tpls files contain the
templates bundled in JavaScript, while the regular version does not
contain the bundled templates. For more information, check out the FAQ
here and the README here.
Alternativelly, if you are only interested in a subset of directives,
you can create your own build.
Whichever method you choose the good news that the overall size of a
download is very small: <76kB for all directives (~20kB with gzip
compression!)
Looks like your error is with a template not begin available or loaded. Maybe you missed the download which packaged the templates. In your case the accordian template isn't being loaded.
After reading the FAQs I'm also wondering if having both angular-ui cdns is causing your problem. The angular-ui is loading first without templates and then your loading angular-ui-bootstrap with templates.
Angular-ui-bootstrap FAQ
This project comes with several deliverables described here:
https://github.com/angular-ui/bootstrap/tree/gh-pages#build-files If
the roles of those files are not clear for you just pick
ui-bootstrap-tpls-[version].min.js, but be sure to include only one
file in your project.
You're showing this
<script src="http://cdnjs.cloudflare.com/ajax/libs/angular-ui/0.4.0/angular-ui.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/0.13.4/ui-bootstrap-tpls.min.js"></script>
Try just loading
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/0.13.4/ui-bootstrap-tpls.min.js"></script>
More info on the builds from github
the excerpt i'm reading is
Now it should be clear that files with the -tpls in their name have
bootstrap-specific templates bundled with directives. For people who
want to take all the directives and don't need to customize anything
the solution is to grab a file named
ui-bootstrap-tpls-[version].min.js. If, on the other hand default
templates are not what you need you could take
ui-bootstrap-[version].min.js and provide your own templates, taking
the default ones
(https://github.com/angular-ui/bootstrap/tree/master/template) as a
starting point.
Did you add 'ui.router' and 'ui.sortable' as dependency in your app.js file ?
var myApp = angular.module('myApp', ['ui.router','ui.sortable']);
I would use a package manager such as Bower or WebPack to manage your client side dependencies.
According to the Angular UI docs you only need to add:
AngularJS and Bootstrap CSS. No need for jQuery.
And then you should initialize your Angular App module with ui.bootstrap dependency:
angular.module('myModule', ['ui.bootstrap']);
== UPDATE
According to this example, this should be everything you need:
index.html
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.4/angular.min.js"></script>
<script src="https://rawgithub.com/angular-ui/ui-sortable/master/src/sortable.js"></script>
```
app.js
var myapp = angular.module('sortableApp', ['ui.sortable']);
Let me know if this helps you

How to use complete AngularJS file in your program?

Up until now I was using links to minified AngularJS files in my code, but now there is a requirement because of which I have to use complete AngularJS file. I have downloaded it from the official site, and:
<script src="../Angular/angular.js"> </script>
<script src="../Angular/angular-animate.js"></script>
<script src="../Angular/angular-aria.js"></script>
<script src="../Angular/angular-cookies.js"></script>
<script src="Angular/angular-loader.js"></script>
<script src="../Angular/angular-message-format.js"></script>
<script src="../Angular/angular-messages.js"></script>
<script src="../Angular/angular-mocks.js"></script>
<script src="../Angular/angular-resource.js"></script>
<script src="../Angular/angular-route.js"></script>
<script src="../Angular/angular-sanitize.js"></script>
<script src="../Angular/angula-scenario.js"></script>
<script src="../Angular/angular-touch.js"></script>
and this is how I added all these files in my code, but it is not working, please let me know what is the correct way of using complete AngularJS file.
Your path for angular-loader is different from the rest of your paths. I'm not sure if any of them are correct. I'd recommend starting the Chrome developer tools and then going to the Network tab to see if all of your resources are loading correctly.
Looking at your codepen it appears that you are reloading the Angular libraries later in your HTML. That is probably causing Angular to reinstantiate and therefore destroying whatever you've done in your code in between. Try deleting or commenting out the lines where you load Angular from cloudflare.

How to add cordova to existing angular project

I've been searching high and low and couldn't get a direct answer or getting my code to work.
I have an existing Angular project that was started via yeoman with Angular and PhoneGap setup together. My setup uses yo and bower to generate the files.
I've tried to import certain cordova plugins to test out like the camera or datepicker and see if it works on the device but it doesn't as it was always saying the calling function is undefined.
So with the current setup I call the code below in one of my submodules
navigator.camera.getPicture(onSuccess,onFail,{sourceType:1,quality:60});
This doesn't work so I tried other tutorials and also by trying ngCordova which is a wrapper class for angular. The following is how it looks like in my index.html
<!-- build:js(.) scripts/vendor.js -->
<script src="phonegap.js"></script>
<!-- bower:js -->
<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/angular-animate/angular-animate.js"></script>
<script src="bower_components/angular-sanitize/angular-sanitize.js"></script>
<script src="bower_components/angular-ui-router/release/angular-ui-router.js"></script>
<script src="bower_components/collide/collide.js"></script>
<script src="bower_components/ionic/release/js/ionic.js"></script>
<script src="bower_components/ionic/release/js/ionic-angular.js"></script>
<script src="bower_components/json3/lib/json3.js"></script>
<script src="bower_components/angular-translate/angular-translate.js"></script>
<script src="bower_components/pouchdb/dist/pouchdb-nightly.js"></script>
<script src="bower_components/angular-pouchdb/angular-pouchdb.js"></script>
<script src="bower_components/proj4/dist/proj4.js"></script>
<script src="bower_components/ngCordova/dist/ng-cordova.js"></script>
<!-- endbower -->
In the tutorials it's asking to have the ng-cordova import above this line which does not exist
<script src="cordova.js"></script>
How do I generate this cordova.js into an existing project and will it conflict with the phonegap.js file?
Just create a new project, add a platform (e.g. ios) with cordova and put the cordova.js file of it into your existing project. Phonegap supports both phonegap.js and cordova.js as stated here. You'll find the file in platforms/ios/www/cordova.js. Then, you're right, the cordova.js has to be included as the last <script> that you include.
