Reusable utilities for FastAPI

Documentation: https://fastapi-utils.davidmontague.xyz

Source Code: https://github.com/dmontagu/fastapi-utils

FastAPI is a modern, fast web framework for building APIs with Python 3.7+.

But if you're here, you probably already knew that!

Features

This package includes a number of utilities to help reduce boilerplate and reuse common functionality across projects:

• Class Based Views: Stop repeating the same dependencies over and over in the signature of related endpoints.
• Response-Model Inferring Router: Let FastAPI infer the response_model to use based on your return type annotation.
• Repeated Tasks: Easily trigger periodic tasks on server startup
• Timing Middleware: Log basic timing information for every request
• SQLAlchemy Sessions: The FastAPISessionMaker class provides an easily-customized SQLAlchemy Session dependency
• OpenAPI Spec Simplification: Simplify your OpenAPI Operation IDs for cleaner output from OpenAPI Generator

It also adds a variety of more basic utilities that are useful across a wide variety of projects:

• APIModel: A reusable pydantic.BaseModel-derived base class with useful defaults
• APISettings: A subclass of pydantic.BaseSettings that makes it easy to configure FastAPI through environment variables
• String-Valued Enums: The StrEnum and CamelStrEnum classes make string-valued enums easier to maintain
• CamelCase Conversions: Convenience functions for converting strings from snake_case to camelCase or PascalCase and back
• GUID Type: The provided GUID type makes it easy to use UUIDs as the primary keys for your database tables

See the docs for more details and examples.

Requirements

This package is intended for use with any recent version of FastAPI (depending on pydantic>=1.0), and Python 3.7+.
