Middleware

A “middleware” is a function that works with every request before it is processed by any specific path operation. And also with every response before returning it.

• It takes each request that comes to your application.

• It can then do something to that request or run any needed code.

• Then it passes the request to be processed by the rest of the application (by some path operation).

• It then takes the response generated by the application (by some path operation).

• It can do something to that response or run any needed code.

• Then it returns the response.

Create a middleware

private_jet = PrivateJet()

class CustomMiddleware:
async def call(self, scope, receive, send):
      print("Custom Middleware")

async def app(scope, receive, send):
if scope["type"] == "http":

      await private_jet.add_middleware(
            CustomMiddleware
      )
      await private_jet.start(scope=scope, receive=receive, send=send)

Built-in middlewares

CORSMiddleware

from privatejet.middlewares import CORSMiddleware

private_jet = PrivateJet()


async def app(scope, receive, send):
if scope["type"] == "http":

      await private_jet.add_middleware(
            CORSMiddleware
      )
      await private_jet.start(scope=scope, receive=receive, send=send)
