Blog REST API
Async FastAPI blog with auto Swagger, filtering, pagination, optimized queries.
FastAPIAsyncSwagger
Problem
A blog API needs clean filtering, pagination and docs that stay in sync — without N+1 queries as posts and comments grow.
Architecture
Async FastAPI endpoints → SQLAlchemy async session → Postgres · Pydantic schemas · auto OpenAPI/Swagger
Key decisions
- Async handlers end-to-end for high concurrency
- Cursor/limit pagination with validated query params
- Separate read and write schemas for posts and comments
