GraphQL provides its architects with the freedom to create their own schemas, and over the years, I have come across various methods of doing so. However, what I’m about to write here is very important – errors made at the beginning of schema design will haunt an entire team throughout a project.
Problems that can arise from a poorly designed GraphQL schema include unauthorized access to data, over-fetching, chaos and messiness, forced execution of a large number of queries instead of one, and unclear relationships between objects.
