SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires fastapi, pydantic, sqlalchemy, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps developers standardize their FastAPI REST API development process by providing guidelines on project structure, type hints, async/await usage, Pydantic validation, and dependency injection.

Core Features & Use Cases

  • Project Structure: Defines a recommended structure for FastAPI projects with directories for main app, core, API, models, schemas, and services.
  • Type Hints: Emphasizes the use of type hints for better code readability and IDE support.
  • Async/Await: Outlines best practices for writing asynchronous code in FastAPI.
  • Pydantic Validation: Provides guidance on using Pydantic for request and response validation.
  • Dependency Injection: Offers examples of dependency injection for database sessions and other services.
  • Use Case: For a developer starting a new FastAPI project, this Skill can help ensure best practices are followed from the beginning.

Quick Start

Use the fastapi-api-standards skill to create a new FastAPI project with the recommended structure and configurations.

Frequently Asked Questions about fastapi-api-standards

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is the recommended project structure for a FastAPI REST API using SQLAlchemy?▼

The recommended FastAPI project structure organizes directories for the main app, core, API, models, schemas, and services. This structure standardizes development by separating data models, Pydantic schemas, and business logic.

How do I use dependency injection for database sessions in FastAPI?▼

Dependency injection in FastAPI manages database sessions by passing SQLAlchemy sessions to route functions. This approach standardizes database access and ensures sessions are properly handled across asynchronous endpoints.

How do I validate request and response data in FastAPI with Pydantic?▼

Pydantic validates FastAPI request and response data by defining schema models with type hints. This ensures automatic data validation and serialization while improving code readability and IDE support.

What are the best practices for writing async/await code in FastAPI?▼

Best practices for async/await in FastAPI involve using asynchronous functions for I/O bound operations and SQLAlchemy async sessions. This maximizes concurrency and prevents blocking the event loop during database queries.

Does this FastAPI standardization approach work for existing projects?▼

Yes, this standardization applies to both new and existing FastAPI projects. You can integrate recommended structures, Pydantic validation, and async dependency injection incrementally into your current codebase.

Do I need SQLAlchemy and Pydantic to standardize my FastAPI project?▼

Yes, standardizing FastAPI development requires SQLAlchemy for database operations and Pydantic for data validation. These dependencies, along with async/await support, form the foundation of the recommended architecture.
