AngularJS minified js files not working

I minified and merged all js files in one and included in html nothing is working in site.
There are so many files in js and I dont want include all one by one, so modified and merged all in one.
Is there any other way to decrease number of http calls for js files.

When minifying your AngularJS documents it is important that you follow the docs for dependancy injection, otherwise your code can break. You should make sure you are using the preferred array method an example can be seen below:
someModule.controller('MyController', ['$scope', 'greeter', function($scope, greeter) {
// ...
}]);
As seen in the official Angular JS docs: https://docs.angularjs.org/guide/di.

It seems, that's a reason of implicit dependency injection. According to the Angular JS documentation:
Careful: If you plan to minify your code, your service names will get renamed and break your app.
Use strict dependency injection instead. For example:
angular
.module("MyModule")
.controller("MyCtrl", ["$scope", "$timeout", function ($scope, $timeout) {
...
}]);
More over, consider using ng-annotate that's much easier:
angular
.module("MyModule")
.controller("MyCtrl", function ($scope, $timeout) {
"ngInject";
...
});

To follow up on #dayle-salmon 's answer, if you have your controllers like this
app.controller('DemoCtrl', function(dependency1, dependency2){
// controller code
});
Change it to
app.controller('DemoCtrl', ['dependency1', 'dependency2', function(dependency1, dependency2){
// controller code
}]);
Reason JS minificators usually change the name of the dependency that is injected. And Angular wont have a clue on what the dependency is. So, you manually declare them so it won't cause a problem after minification!

The $routeProvider in Angular can't be found in undefined

I'm following a guide on how to include AngularJS in a MVC project and I got to the point where I'm connecting my controllers (the section's name is Routing).
It seems not to work and when I open the console, I see the following error message.
TypeError: Cannot read property '$routeProvider' of undefined
I've checked all the files in the solution for that string and the only usage of it is in the file where I registered my module. It looks like this.
var CoolApp = angular.module('CoolApp', ["ngRoute"]);
CoolApp.controller('CoolController', CoolController);
var configFunction = function ($routeProvider) {
$routeProvider
.when("/one", { templateUrl: "angularRoute/first" })
.when("/two", { templateUrl: "angularRoute/second" })
.when("/thr", { templateUrl: "angularRoute/third" });
}
configFunction.$inject["$routeProvider"];
CoolApp.config(configFunction);
I have MVC controller class named AngularRouteController and as far I can see, the only place where I'm "dotting" the $routeProvider is in when statements. Commenting them out doesn't resolve my issue, though. Instead, the line that seems to be the cause of the error is this one.
configFunction.$inject["$routeProvider"];
Due to my ignorance with Angular, I can't see why. As a consequence, I have no idea how to solve the problem. Any suggestions would be welcome. I've googled the issue but that didn't give me anything useful (as far I could judge).
The closest hits I've got was this and this one and they didn't make me any wiser. Not even sure if those are relevant to my problem.
I've made sure that I reference the routing package of Angular separately as suggested in this answer. Should I skip ngRoute and go for ui.router? Not sure what that changes for the guide...

It looks like you have to change that line to:
configFunction.$inject = [
"$routeProvider"
];

Injecting Angular modules: Unknown provider

I followed a tutorial on how to organize and Angular project. I have a ng directory that contains all my controllers, services and my routes.js. This is then bundled all together into an app.js by my gulp config.
My module.js is like this:
var app = angular.module('app', [
'ngRoute',
'ui.bootstrap'
]);
Here's a bit of my routes.js:
angular.module('app')
.config(function ($routeProvider) {
.when('/login', { controller: 'LoginCtrl', templateUrl: 'login.html'})
});
Here's what my working LoginCtrl looks like:
angular.module('app')
.controller('LoginCtrl', function($scope, UserSvc) {
$scope.login = function(username, password) {
...
}
})
The tutorial didn't make use of any Angular modules and I wanted to try one out. I added ui.bootstrap to my page from a CDN and try to change the LoginCtrl to:
angular.module('app')
.controller('LoginCtrl', function($scope, $uibModal, UserSvc) {
...
})
But this throws me the following error:
"Error: [$injector:unpr] Unknown provider: $templateRequestProvider <- $templateRequest <- $uibModal
What is causing this error? In every tutorial I find this seems to be how they load a module, the only difference I see is that the tutorial don't seem to be using a router.
PS: Note that if I use an empty module list [] I get the exact same error. If I use a non-existing module ['helloworld'] I get an errorModule 'helloworld' is not available'. So I'm concluding that my `ui.bootstrap' module is indeed available.
EDIT: Plunker fiddle here: http://plnkr.co/edit/FWHQ5ZDAByOWsL9YeMUH?p=preview

angular route is another module you should not only include but also use like this
in the app module creation
means DI of route
angular.module('app', ['ngRoute']);
Please go through the angular route doc

Remove ['ui.bootstrap'] form controller. You should add dependencies only one time but you add it twice so the second dependency list override the first one.
angular.module('app')
.controller('LoginCtrl', function($scope, UserSvc) {
... })

your routes snippet looks wrong, you should be hanging the when call off $routeProvider and maybe declare $routeProvider as an injected val if it's not being picked up e.g.
angular.module('app')
.config(["$routeProvider", function ($routeProvider) {
$routeProvider.when('/login', { controller: 'LoginCtrl', templateUrl: 'login.html'})
}]);

I have checked your link. I think there is a serious issue with angular and ui bootstrap version.In ui-boostrap dashboard, it is written that 0.12.0 is the last version that supports AngularJS 1.2.x. I have tried with all combinations but it doesn't work with your angular version.
I suggest you to change angular version to latest and ui-bootstrap version to latest so it will work.
Please check out this working Plukr
<script src='https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.8/angular.min.js'></script>
<script src='https://ajax.googleapis.com/ajax/libs/angularjs/1.2.18/angular-route.js'></script> //change this to latest also.
<script src='https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/1.0.3/ui-bootstrap.min.js'></script>
<script src='./app.js'></script>
If you want to go with your angular version only. I'd request you to do some R&D. Try with different versions of ui-bootstrap. still if it doesn't work you can make PR.

AngularJS : get translate key in app.js

In my application, I use the AngularJS module Pascal Precht (translate module). I come to you because I can not get in my method myApp.Run of app.js a translation key.
I can do in a controller or a view. But impossible to get it at the initialization of the project. It shows me the key, not correspondence.
Do you have a solution?
Here is my code:
var myApp = angular.module('myApp', ['ngRoute', 'ngAnimate', 'myApp.filters', 'myApp.services', 'myApp.directives', 'pascalprecht.translate']);
// Declare routeProvider
myApp.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/', {templateUrl:'partials/connectView.html', controller:'ConnectController'});
$routeProvider.when('/homeView', {templateUrl:'partials/homeView.html', controller:'HomeController'});
}]);
// Declare translateProvider
myApp.config(['$translateProvider', function($translateProvider) {
$translateProvider.useStaticFilesLoader({
prefix: 'res/localization/lang-',
suffix: '.json'
});
$translateProvider.preferredLanguage('fr_FR');
//$translateProvider.preferredLanguage('en_US');
}]);
// Declare Global variables
myApp.run(['$rootScope', '$filter', function($rootScope, $filter) {
$rootScope.list = false;
etc....
//I'm trying to get translate Key but it doesn't work
console.log($filter('translate')('MY_KEY'));
}]);
My AngularJS version is 1.2.16 (last stable version). Thx

Try injecting the $translate service in app.run().
angular-translate version 1.1.1 and below
myApp.run(['$rootScope', '$translate', '$log', function ($rootScope, $translate, $log) {
$log.debug($translate('MY_KEY'));
}]);
I'd also suggest you to upgrade to the latest version of Pascal Precht's angular-translate. There are some changes in the new version.
angular-translate version 2.0.0 and above
myApp.run(['$rootScope', '$translate', '$log', function ($rootScope, $translate, $log) {
// translate via promises (recommended way)
$translate(['MY_KEY', 'MY_OTHER_KEY'])
.then(function (translation) {
$log.debug(translation.MY_KEY);
});
// translate instantly from the internal state of loaded translation
$log.debug($translate.instant('MY_KEY'));
}]);
See this helpful migration guide.

Why don't you inject the $translate service in the run section
and then call it instead of using the filter?!
console.log($translate('MY_KEY'));

Well, Apparently I can't comment because of reputation issue, we came across something that might be what you are experiencing - since the locale file is downloaded only in the config part of angular, it might not be available (yet) when you call the translate.
We solved this by adding all the locale files upfront (we don't have many and they are small) and in the initialization we just choose the correct one, that way we avoid the problem.
(again this should probably be more of a comment then an answer, but I can't comment...)

This is not a solution for your issue, but if you try the following code in your 'run', you will get an idea, why the translation is not available at the initializing state.
myApp.run(['$rootScope', '$filter','$timeout', function($rootScope, $filter,$timeout) {
$timeout(function(){
alert($filter('translate')('MY_KEY'));
},5000)
}]);
Problem here is, by the time the translation is being loaded the 'run' will be executed. So it cannot be assured that you will get the translation loaded at that time.

AngularJS + Rails - Problems when compressing assets

I recently created an AngularJS 1.0.0rc8 app with a Rails 3.2.3 back-end and it worked fine in development, but after deploying to Heroku there was a Unknown Provider error - apparently the app could not see the service object.
I know that it's now necessary to include angular-resource.js as a separate file and inject ngResource into the app module like this:
// main app javascript file
'use strict';
angular.module('contactapp', ['ngResource']).
config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/contacts', {template: 'assets/app/partials/contact-list.html', controller: ContactListCtrl}).
when('/contacts/new', {template: 'assets/app/partials/new-contact.html', controller: ContactListCtrl}).
when('/contacts/:contact_id', {template: 'assets/app/partials/contact-detail.html', controller: ContactDetailCtrl}).
otherwise({redirectTo: '/contacts'});
}]);
I also know that when files are minified that the controllers can't tell what their dependencies are unless they are also injected into the controller objects like this:
ContactListCtrl.$inject = ['$scope', '$http', 'Contacts'];
I've also tried doing it the other way that Angular recommends with bracket notation and passing in a function like this:
var ContactListCtrl= ['$scope', '$http', 'Contacts', function($scope, $http, Contacts) { /* constructor body */ }];
However, none of this seems to work.
The only way my application could see the resource provided was by turning off asset compression in the Production.rb file, like this:
# Compress JavaScripts and CSS
config.assets.compress = false
It took several hours for me to figure this out, but I recently saw another Rails + AngularJS app that had the same issue.
Jens Krause came to the same conclusion and explains it on his blog: http://www.websector.de/blog/2012/01/17/fun-with-angularjs-rails-coffeescript-sass-another-cafe-townsend-example/
If I have a relatively large app, and I need to compress the assets, how do I get around this using Angular with Rails?
Thanks.

If you're using Rails 4, change your js_compressor in your production and staging environments to:
config.assets.js_compressor = Uglifier.new(mangle: false)

I think the problem is that your minifier is still obfusticating the variable name of the control itself (ContactListCtrl -> a or whatever it does).
Have you tried defining your controllers with the module.controller function?
angular.module('myModule', [])
.controller('Controller1', ['dep1', 'dep2', function(dep1, dep2) {
//code
}]);

Adding this line to my config/environments/production.rb did the trick for me:
config.assets.js_compressor = Sprockets::LazyCompressor.new { Uglifier.new(:mangle => false) }
