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 REST, get
from autumn.response import JSONResponse

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

Key Points

• @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.
• The controller module must be imported by the application or discovered by Autumn during startup.
