SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

What problem does it solve?

Developers need a consistent, secure pattern to add REST endpoints to FastAPI applications without repeating boilerplate or making common mistakes around authentication, typing, and HTTP semantics.

Core Features & Use Cases

Standardized CRUD templates: Ready-to-use router template with create, read, update, and delete endpoints that follow FastAPI conventions.
Authentication and dependencies: Patterns for optional and required authentication using Depends and for injecting service layers.
Robust API contracts: Enforces async endpoints, Pydantic response models, validated query/path parameters, proper HTTP status codes, and HTTPException-based error handling.
Use Case: Add a new resource router (projects, tasks, users) to a backend with correct routing, response models, and auth checks in minutes.

Quick Start

Create a new router by copying the provided template file, replace the placeholder names with your resource model names, and mount the router in your FastAPI main app.

FAQPage Schema

How do I create FastAPI CRUD endpoints with authentication?▼

FastAPI CRUD endpoints with authentication are generated using a router template that enforces async routes, applies Depends for auth injections, and uses HTTPException to handle errors, delivering secure REST endpoints instantly.

What is the best way to structure Pydantic response models in FastAPI?▼

Structuring Pydantic response models in FastAPI involves defining schemas for your resources and applying them to CRUD endpoints, ensuring validated query parameters and proper HTTP status codes across create, read, update, and delete operations.

How do I mount a new resource router in a Python FastAPI backend?▼

Mounting a resource router in a Python FastAPI backend requires copying a template file, replacing placeholder names with your target resource model, and including the router in your main application to add REST endpoints rapidly.

Does FastAPI dependency injection work for optional authentication?▼

FastAPI dependency injection supports both optional and required authentication patterns using Depends, allowing you to inject service layers and enforce access control dynamically across your CRUD endpoints.

Why does my FastAPI router return incorrect HTTP status codes?▼

Incorrect HTTP status codes in FastAPI routers often occur when boilerplate is written manually; using a standardized template enforces correct status codes for each CRUD operation and leverages HTTPException for robust API contracts.
