Module is not available, misspelled or forgot to load (but I didn't)
It should be
var app = angular.module("MesaViewer", []);This is the syntax you need to define a module and you need the array to show it has no dependencies.
You use the
angular.module("MesaViewer");syntax when you are referencing a module you've already defined.
You are improperly declaring your main module, it requires a second dependencies array argument when creating a module, otherwise it is a reference to an existing module
Change:
var app = angular.module("MesaViewer");To:
var app = angular.module("MesaViewer",[]);
I had the same error and fixed it.It turned out to be a silly reason.
This was the culprit:
<script src="app.js"/>Fix:
<script src="app.js"></script>
Make sure your script tag is ended properly!
