This gist is in response to a question asked on the Reddit Angular JS forum about how to structure an Angular app with roles and permissions.

There are many ways to approach this, but I'll share one that I've used before and maybe it will give you an idea. I'd combine all of the above into a single app and control who gets to see what using permissions. There are a few components to this approach...

A local session service

First off I'd advise creating some sort of local session management service. This should be able to track whether you have an authenticated user and- if so- what types of permissions that user has. (Lots of ways to manage permissions. I'll assume your user object has either a 'role' enum or something simple like an array of string permissions.) You could roll your own session service or you could check out something like satellizer.

Let's assume yo

TypeScript and currying

In functional programming you often want to apply a function partly. A simple example is a function add. It would be nice if we could use add like:

var res2 = add(1, 3); // => 4

var add10To = add(10);
var res = add10To(5); // => 15

# So, why would you do this when you could just call the sqlpackage.exe directly? 
# Because Powershell provides a higher level of orchestration; I plan to call this script from another script that
