Middlewares

How it works

In jija, middlewares are used to process requests before and after they are passed to the view.

In startup jija collecting middlewares from all apps and core app from middlewares.py in each app, middlewares.py should contain a subclasses of jija.middleware.Middleware, it will be included in order of definition. Request for subapp will be processed by middlewares from core app and subapp, then if you want add some middleware for all apps you can add it to core app.

Default middlewares

By default jija uses some middlewares: jija.middlewares.print_request.

Creating a custom middleware

To create a custom middleware, you need to create middlewares.py in your app and add a class that inherits from jija.middleware.Middleware and implement the handler method.

from jija import middleware

class MyMiddleware(middleware.Middleware):
    async def handler(self, request, handler):
        # add your logic here
        return await handler(request)
