Yes, there is package dexie-relationships. I've tried it but finally remove. Cuz:

  1. indexedDb does not have real relationships like I used to in MySQL. This library is just sugar over dexie.
  2. I faced problem with drop table, cuz reltionships library does not accepts null in table definition (tries to null.split() it).
  3. Instead of that library I use simple repositories (classes or functions) to fetch all required data with short syntax. And so you don't need relationships library cuz all relations are hidden in repositories and you don't need to use relations directly.
  4. Dexie v3.0 is now in beta.1 stage and I don't know whether compatible with dexie-relationships or would ever.

PS: too late, but I think it should be published. It would save me a lot of time if I read this few month before.
