SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill provides a structured approach to organizing FastAPI routing by promoting a modular router pattern and a file-based routing option, helping teams scale complex APIs with maintainable code.

Core Features & Use Cases

  • Modular Router Pattern: Define routers in src/api/v1/endpoints and compose them in an aggregator to keep routes organized and versioned.
  • File-Based Routing (optional): Enable URL structures that mirror the filesystem for quick navigation in smaller projects or rapid prototyping.
  • Versioned API Architecture: Promote consistent versioning and clear separation of concerns across API surfaces.
  • Best Practices: Use tags, prefixes, and dependencies at the router level to simplify OpenAPI docs and reuse.

Quick Start

Create a modular router setup under src/api/v1/endpoints with users.py, items.py, and auth.py, then create src/api/v1/api.py to aggregate routers with appropriate prefixes and tags. Update your project’s startup to include the v1 router and test with a few sample requests to verify routing behavior.

FAQPage Schema
How do I organize FastAPI routing for a large project with multiple modules?

Organize FastAPI routing for large projects by applying a modular router pattern. Define endpoint routers in src/api/v1/endpoints and compose them using an aggregator in src/api/v1/api.py to maintain separation of concerns and scalable code.

What is the best way to structure versioned endpoints in FastAPI?

The best way to structure versioned endpoints in FastAPI is using a versioned API architecture. Place endpoint modules under src/api/v1/endpoints and aggregate them in src/api/v1/api.py with appropriate prefixes and tags for consistent versioning.

Can I use file-based routing in FastAPI to mirror my filesystem structure?

Yes, you can use file-based routing in FastAPI. This optional feature enables URL structures that mirror the filesystem, which is useful for quick navigation in smaller projects or rapid prototyping.

How do I use tags and prefixes to simplify FastAPI OpenAPI documentation?

Simplify FastAPI OpenAPI documentation by applying tags, prefixes, and dependencies at the router level. This practice organizes routes logically and ensures clear separation of concerns across different API surfaces.

When should I use a modular router pattern versus file-based routing in FastAPI?

Use a modular router pattern for large FastAPI projects with multiple modules and API versions. File-based routing is better suited for smaller projects or rapid prototyping where you need URL structures that mirror the filesystem for quick navigation.

Does this FastAPI routing approach work for teams building scalable APIs?

Yes, this FastAPI routing approach is designed for teams building scalable APIs. It promotes a modular router pattern and versioned architecture, helping teams manage complex APIs with maintainable code across multiple modules and endpoints.
