We just need a tool to let every REST/rpc endpoint gain the ability of 'resolve' and 'dataloader' from GQL, to provide rich detailed view data to frontend (in just single call)

So that: 1. we enjoy the current tech stack from REST/rpc 2. we gain the ability of quick composition from resolver / dataloader 3. with iteration, we can replace/ refactor endpoint without breaking anything.

for fastapi user, the lib 'pydantic-resolve' can help.
