SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill standardizes how backend API routes are built in FastAPI projects, ensuring consistent structure, security, and maintainability across services.

Core Features & Use Cases

Uniform route patterns: Enforce use of APIRouter with a common /api prefix, and standardized tagging for OpenAPI.
Dependency injection: Promote automatic management of database sessions via FastAPI Depends.
Security & validation: Enforce JWT-based authentication, path/query validation with Pydantic models, and consistent error handling.
Service layer alignment: Encourage delegating business logic to service modules to separate concerns.

Quick Start

Create a new route by following the documented patterns. Example: define a router in backend/routes, apply APIRouter(prefix="/api"), add dependencies (db: Session = Depends(get_db), current_user: dict = Depends(verify_jwt_token)), validate inputs with Pydantic models, and return a standardized response. Then wire the router into the application.

FAQPage Schema

How do I structure FastAPI routes for consistency and security?▼

Structure FastAPI routes by using APIRouter with a '/api' prefix, applying dependency injection for database sessions, enforcing JWT verification, and validating inputs with Pydantic models for consistent, secure endpoints.

What's the best way to add JWT authentication to FastAPI endpoints?▼

Add JWT authentication to FastAPI endpoints by configuring a dependency function like verify_jwt_token and injecting it into your route definitions using FastAPI Depends to secure protected resources.

How do I validate request data in FastAPI using Pydantic?▼

Validate request data in FastAPI by defining Pydantic models for your path and query parameters, then applying them to route signatures to automatically enforce validation and standardize error handling.

Can I use dependency injection for database sessions in FastAPI routing?▼

Yes, you can use dependency injection for database sessions in FastAPI routing by applying Depends(get_db) to your endpoint parameters, which automatically manages session creation and teardown.

How do I organize FastAPI endpoints to separate business logic from routing?▼

Organize FastAPI endpoints by delegating business logic to dedicated service modules, keeping your APIRouter definitions focused on handling HTTP requests, validating inputs, and returning standardized responses.

Does FastAPI support standardizing OpenAPI documentation across multiple routes?▼

FastAPI supports standardizing OpenAPI documentation by applying consistent OpenAPI tagging to your APIRouter definitions, ensuring all endpoints are grouped logically and documented uniformly across the application.
