Source Code: https://github.com/maxim-f1/quick_jwt

---

Quick JWT is a lightweight and convenient solution for handling JWT token-based authorization.

The key features are:

• Full integration with FastAPI framework and Intuitive use of FastAPI style features.
• Easy customization of environment variables via Pydantic-Settings and Middleware.
• Convenient functions for wrapping Depends with data type persistence.
• Many Depends functions for a large number of tasks.
• Ability to customize standard PyJWT driver to custom solutions.
• Support for function arguments for PyJWT driver, as well as Pydantic validation functions.

Requirements

Quick JWT stands on the shoulders of giants:

• FastAPI - main web framework.
• PyJWT - default JWT driver.
• Pydantic Settings - extension for pydantic with .env variables.

Installation

Create and activate a virtual environment and then install Quick JWT:

$ pip install quick-jwt

Example

Create it

Create a file main.py with:

from fastapi import FastAPI
from pydantic import BaseModel
from quick_jwt import (
    QuickJWTConfig,
    QuickJWTMiddleware,
    create_jwt_depends,
)

key = "default_key"
quick_jwt_config = QuickJWTConfig(encode_key=key, decode_key=key)

app = FastAPI()
app.add_middleware(QuickJWTMiddleware, quick_jwt_config)


class UserScheme(BaseModel):
    sub: str


@app.get("/create-tokens")
async def create_tokens(
    sub: str, 
    jwt: create_jwt_depends(UserScheme, UserScheme)
):
    user = UserScheme(sub=sub)
    tokens = await jwt.create_jwt_tokens(user, user)
    return tokens

Run it

Run the server with:

$ fastapi dev main.py
