swagger-angular-generator | Generator of API layer in TypeScript for Angular 2 apps | REST library

I'm currently working with an API that's a bit of a pain :D The API doesn't return full information needed for my app and that means I have to make multiple calls to get the full information required. Also, I'm struggling to keep my head round it so if it's not well explained just let me know!

Main Details of Issue

The current API flow looks a little like this:

1. Get a list of 'Group ID's' (see response 1).

2. Using that list, for each Group ID, get the Group Details and Types in the Group (see response 2).

3. Using the group details, for each type, get the type name (see response 3).

4. Build a big tree with all the details.

5. Using a separate end point, get all 'skills' and update the tree accordingly (see response 4).

The problem comes when trying to return the correct values in the correct place which is all out of sync since I'm nesting promises in promises in async promises :O

The main API endpoints and examples can be found at https://esi.tech.ccp.is/latest/.

My current code looks a little like the below (I've tried to list functions in the order they are called).

The problem is, I need to locate the point where:

• The list of groups has been returned.

• For each group the types included have been returned.

• the skillTree object has had a new property added which is under the format below.
