Strapi: what is best way to combine multiply Collections in one endpoint?

Question

lets imagine that we have 2 independent data collections:

1. menu (contains labels + links [])
2. posts (contains text [])

By default Strapi gives me 2 endpoints, one for menu and another for posts. That's fine, but how I can combine this two (or even 10+ small data collections) in one Strapi REST API response?

I'm new to Strapi so need most simple and effective solution. I know that possible to make a custom endpoint but in this case I should manually add/remove any collections inside Strapi config - think its not a true way.

Thank you for your time!

Answer 1

You can also create another collection e.g. agg_collection that has relations to both collections so you can retrieve them by calling api/agg_collection?populate=....

Writing a custom endpoint is the preferred solution I suppose, but the question is; do you really need to have it in a single request?
