Hello Controller

Controllers in Autumn act as the transport layer. They receive HTTP requests, delegate business logic to the appropriate services, and produce the HTTP response.

Your First Route

from autumn.controller import get
from autumn.response import JSONResponse

from app import app

@app.rest(prefix = '/hello')
class HelloController:
    @get('/')
    async def index(self) -> JSONResponse:
        return JSONResponse({
            'message': 'Hello from Autumn'
        })

Key Points

• @app.rest(...) groups routes within a single controller and defines a shared prefix.
• @get('/') defines the HTTP method and path for the handler.
• JSONResponse serializes the dict to JSON and returns a proper HTTP response with the required headers.
