I am working with AngularJS from a short amount of time so I am still a kind of lost with it. Sorry if the question is trivial or was already asked... I have seen so many different questions / posts / docs that I am really confused.
This is the problem I am facing: I would like to dynamically add dependencies to my app (I am going to refer to it as rootApp), before bootstrap it.
At the moment the bootstrap happens manually: for what I have read on the web, should be possible to dynamically add dependencies to the app before bootstrap it (and that is why the bootstrap is happening manually).
I have different templates (powered by Template Toolkit) that can load different modules as dependency: for example, the template "myComponent" needs to load, as dependency, the Angular module myComponent; the template "myTable" needs to load, as dependency, the Angular module NGTable, etc...
What I would like to do is to define the module for the rootApp as:
// NOTE: no dependencies as argument!
rootAppModule = angular.module('rootApp', []);
and then add dependencies on demand, something like:
rootAppModule.pushDependency( myComponentModule );
rootAppModule.pushDependency( NGTableModule );
then finally bootstrap:
angular.bootstrap(document, ['rootAppModule']);
Someone can help me?
PS I have seen there are Angular plugins to load dependencies AFTER the bootstrap of the app but here I would be happy doing it before the bootstrap. It should be easier, so I would prefer to avoid (not needed?) complexity.
edit:
I have found the array "requires", follows an example:
angular.module("rootAppModule").requires.push("myComponentModule");
from here
Anybody can tell if that is a reliable solution?
Well, this was already in the "edit" but a friend told me that is good habit to answer own questions when there is an answer, so here it is:
I have found the array "requires", follows an example: angular.module("rootAppModule").requires.push("myComponentModule");
from here
Anybody can tell if that is a reliable solution?
Thanks.

I am trying to develop a desktop application using Electron. I am also using AngularJS.
The problem I am running into is that when I create a custom directive, and load a templateUrl, the view doesn't load and the console says it doesn't exist. Yes, the path is correct, I am sure of it.
The problem is that the application is already running index.html, so it can't load the second file. Needless to say, I am not experienced enough to solve this problem on my own.
I know that Electron uses node on the backend, so I suppose setting routes and/or setting a path to my static files might resolve the problem, but I don't know how to do it.
I have searched the whole web for a solution, but I couldn't find a clear answer.
One way you could easily do it, is by adding your template as an inline template on the angular side, for example in your index.html:
<script type="text/ng-template" id="temp1.html">
....
</script>
Then you can reference it from your directive, like templateUrl: temp1.html.
Otherwise, you could also use a module bundler. Webpack has a ng-template loader which does that for you. Gulp and Grunt also have equivalents
Another thing to try, if you need to reference paths from the js side, is to use __dirname nodejs variable. Here an example
Just started a demo Angular2 project (no previous experience with Angular1/AngularJS. Have followed and extended from the online quickstart and tutorials, and all was fine. However I'm at the point where I would like to use some components from a library which is designed for AngularJS, and having no end of problems!
Most of the information available about AngularJS/Angular2 compatibility assumes that you have an AngularJS project that you're adding Angular2 components to - not the other way around - so what I'm hoping to do may not even be possible. What I've tried so far involves a simple stripped-back project based on the Angular2 quickstart, with a single Angular2 component that loads into the index.html. I'd then like to integrate components from the existing library (AngularJS-based) into this.
I've tried using UpgradeAdapter.upgradeNg1Component to create components from the library and add them directly into my Angular2 component
I've tried installing angularjs through npm, importing it in a script tag into my index.html and then using a combination of UpgradeAdapter.downgradeNg2Component and UpgradeAdapter.bootstrap to load my Angular2 as a downgraded module
Neither of these seem to work - the component fails to show, and the browser console tells me I've got an Uncaught SyntaxError: Unexpected token <
Evaluating http://localhost:3000/angular2/upgrade
Error loading http://localhost:3000/app/main.js
My best guess at the moment is that this is actually an unsupported scenario, and I need to have a 'proper' AngularJS app in order to use the UpgradeAdapter functionality from Angular2. Can anyone confirm this? Or is there something stupid I'm missing here?
Here is a working plunkr describing how to mix Angular1 and Angular2 elements:
http://plnkr.co/edit/yMjghOFhFWuY8G1fVIEg?p=preview
An important point is to bootstrap your main component on the UpgradeAdapter. This way all elements are available in providers (services / factories) and in directives (components / directives):
upgrade.bootstrap(document.body, ['heroApp']);

How to inject upgraded Angular 1 service/factory to Angular 2 component in ES5?
So the major problem in this case turned out to be the fact that it appears that the upgrade components aren't included as part of the basic angular 2 bundle. After adding:
<script src="node_modules/angular2/bundles/upgrade.min.js"></script>
to my index.html file the error I was seeing disappeared.
Thanks to the answer here for pointing me in the right direction!
After reading hundreds of lines about browserify vs webpack and several how to of both I decided to go for webpack. The main reason it's because I liked the idea of bundling everything into a js file.
I have an angular project already working and I want to refactor it for webpack. The problem? My project is using angular 1.4.7, ng-animate and plain javascript (ES5) and all the tutorials and manuals are for ES6. I don't want to refactor my project so much. What's the way to go? I would like an example of each angular module : factory, directive, controller and so on. Many thanks
I typically have a feature.module.js file which has my module definition and requires all of the directives / services contained within the module. Also has the external dependancies.
/* module.js */
angular.module('my.module',['dependancy1', 'dependancy2']);
//External libraries
require('./dependancy1.module.js');
require('./dependancy2.module.js');
//Internal components
require('./thing.directive');
require('./thing.service';
/* service.js */
angular.module('my.module')
.directive('yourDir', function myDir(){...});
I'm dealing with the same problem now. And I found something that works (work in progress, but at least I can see progress). My steps:
Install yeoman
Run this angular-webpack generator. Select 'ES5' when asked (the other option is 'ES2015', which I guess is the same that 'ES6')
Start modifying the automatically generated boilerplate with your Angular code
Yes, you still need to learn about gulp and sass, but at least you can run a simple AngularJS app using the old ES5 syntax, and start modifying it.
I'm probably blogging about this. So, I'll update this answer then.
I tend to do this:
app.js:
require('/any/angular/deps');
var subModule = require('/some/sub/module');
var app = angular.module('myApp', []);
// pass the app module in sub modules to allow them to define their own config
subModule.configure(app);
/subModule/module.js:
var someSubDirective = require('./subDir/directive');
export function configure(app) {
someSubDirective.configure(app);
}
/subModule/subDir/directive.js:
export function configure(app) {
app.directive('myDir', myDir);
}
function myDir() {
}
My idea is to let all sub modules handle their own configuration, so declaring config or constant, factories or providers. Letting this then bubble up to the app.js. This means its really easy to delete a folder from your structure, because it is one line removal from it's parent module.
This also makes relevant file paths a lot shorter and easier to handle.
I'm working on an Angular app using:
`<html ng-app="navops"></html>`
and we hired a designer how gave me a minified JS script and he is using:
angular.bootstrap(element,modules,config);
so this create an error:
App Already Bootstrapped with this Element '<body>'
how can I integrate the two codes??
You are bootstrapping twice, remove the ng-app from the body tag and it will work. If your code then no longer works make sure you add it as a dependency into the bootstrap() command. Presumably you would just add "myLibs" or something into the modules array
I have a web app I am launching from Eclipse using Spring Boot. I am trying to use Angular modals to have a nice looking confirm delete modal and I was following this tutorial to get the right dependencies. The Bower install seemed to go well:
bower install angular-modal-service --save
And I copy this into my html:
<script src="bower_components\angular-modal-service\dst\angular-modal-service.min.js"></script>
And I add the dependency in my Angular file:
var app = angular.module('myApp', ['angularModalService']);
But that is the point at which it fails. If I launch my app I just get a blank page, nothing at all loads. My console output from Chrome's developer tools gives me:
Uncaught Error: No module: angularModalService
This is a general problem I have had, anytime I try to add a dependency with something like
var app = angular.module('myApp', ['DEPENDENCY']);
it doesn't work. Is there something more I need to do in Eclipse in order for it to get it to pick up on my Bower dependencies?
When you have such problem, we can't resolve it for you.
But we can give you some advices to resolve this kind of problem :
Identify the problem. Open the developper tools of your navigator (F12), then the console. If you have nothing here, try to refresh. Angular will let you know if there is a dependency injection problem.
Check if you didn't forgot something. You have to import in your page angular, THEN angular-modal-service, THEN your application. The order is important.
Check if the module you want to use doesn't depend to something else. In your case, do this module needs bootstrap JS files ? Again, take a look at the console. It's here to help you.
Perhaps not specifying type="text/javascript in the script declaration causes your browser not to parse and execute the script? It is required in HTML < 5. Try adding that. Maybe that will help. Post your HTML file, if it still does not work.
