There’s one big problem that you will eventually uncover as you spend more hours developing your GraphQL API. The problem doesn’t give you any errors nor it is obvious to developers — the “N+1” problem.
The goal of this article is to shed some light on how one could use Dataloader to address the “N+1” problem in Graphene Django while creating a GraphQL API for the One-to-Many and Many-to-One relationship between tables.
In case you are lost somewhere in between or you would like to try out everything on your own, you may find the source code here at GitHub.
I will also be using Insomnia REST Client to test out the APIs in this article. If you are interested to learn more about Insomnia, check out this article:
