This question is probably above my pay grade 
How I’ve seen most angular applications do this is they, unfortunately, need to build it themselves. They do a call to a configuration file on the server to configure the modules.
Two ways that I’ve seen in live applications…
- Make an http.get to a configuration file on the server
- Use an environment.js file that is loaded before your angular app that sets some values, that you can modify during build time per environment.
I’m not super familiar with octopus functionality though. They might have some other ideas.
