Key features are:

• Light: Routerfy's lambda layer it's extremely light since it does not need any additional library to redirect routes.
• Fast to test: Increase the speed to test new features by about 500%.
• Fast to build templates: Building AWS templates never been that easy. Routerfy create all AWS templates with necessary properties but still customizable.
• Familiar Syntax: Routerfy use same syntax of FastAPI for routes creation turning the experience of migration a lot easier.
• Body Validation: Routerfy have an own route body validation like pydantic but lighter using no dependencies.

Requirements

Python 3.7+

For development serving, Routerfy uses the amazing ones:

• FastAPI for route management.
• Uvicorn for ASGI server.

Installation

For development:

pip install routerfy[dev]

For AWS Lambda layer:

pip install routerfy

Getting Started

To create your first Routerfy project you only need to use create command. Open CMD in the folder you want to create your project and insert:

routerfy create MyAwesomeRouterfyProject

If everything go well the project folder created will look like this:

.
├─ routes/
│  ├─ hello_world/
│  │  ├─ app.py
│  │  ├─ route.py
└─ routerfy.config.yaml

Example

Our first example file is the route.py inside the lambda folder hello_world. All lambda folders must have a route.py. this way routerfy can identify routers and make the magic happens.

from routerfy import APIRouter, Response

router = APIRouter(prefix="/hello")

@router.get("/")
def hello_world_get_request():
    return "Hello World!"

As you can see, the syntax is very similar to FastAPI.

Testing application

To test application you only need to use the dev command on your project terminal:

routerfy dev

The server will start and you will have your routerfy application served locally!
