Request Handlers

Function-based handlers

Request handlers are callables that return a Response or any object (which is auto‑wrapped in Response). Register handlers using @app.route, @app.get, @app.post, etc.:

from jetweb import JetWeb, Request, Response

app = JetWeb()


@app.route("/hello", methods=["GET"])
def hello(request: Request) -> Response:
    return Response(content="Hello, World!")


app.run()

If a handler returns a plain object or string, JetWeb wraps it in a Response automatically:

@app.get("/ping")
def ping(request: Request) -> dict:
    return {"status": "ok"}

Class-based handlers

Class-based handlers must inherit from BaseHandler and be decorated like function-based handlers. HTTP methods (get, post, etc.) are defined as instance methods:

@app.route("/hello")
class HelloHandler(BaseHandler):
    def get(self, request: Request) -> str:
        return "Hello from GET!"

    def post(self, request: Request) -> str:
        return "Hello from POST!"
