Why isn't AngularJS fully initialized?

Question

Angular

I'm playing with a new project, for which I wrote several automation scripts.
After running all the gulp tasks, the dist folder looks like this:

js/
--vendor.js
--app.js
index.html

All paths in index.html are connected correctly, the angular variable is defined in the Chrome console, i.e. scripts are connected correctly for sure.
The problem is that it is not possible to create a controller or configure via angular.module.('app').config().
Even such a basic construction in index.html does not work

<div ng-app>
<input type="text" ng-model="textVal">
<span>{{textval}}</span>
</div>

What can be wrong?

Answer 1

Did you write the ngController declaration in the html file?

<div ng-app>
<div ng-controller='Имя контроллера'>
<input type="text" ng-model="textVal">
<span>{{textval}}</span>
</div>
</div>

Still remembered. angular.module.('app') just returns the module instance. To create a module, use:
angular.module('app',[])
That is, specifying dependencies with a comma creates a module, without specifying - it simply returns an already created module
