After authentication, Batman was worried about the website traffic during the rush hours. He was worried about the server crashing when Joker would try to break all the criminals from the Arkham asylum one more time. So, Robyn told him about the
Const Requests feature and the multi-core scaling potential.
Robyn told Batman that you can pre-compute the response for each route. This will compute the response even before execution. This will improve the response time bypassing the need to access the router.
@app.get("/", const=True) async def h(): return "Hello, world"
Robyn told Batman that he can use the
--workers flag to scale the application to multiple cores. This will create multiple instances of the application and will distribute the load among them. This will improve the performance of the application.
python3 app.py --workers=N --process=M
The authenticate method should return an
Identity object if the user is authenticated, or
None otherwise. The Identity object can contain any data you want, and will be accessible in the route methods using the
Note: that this authentication system is basically only using a
before request middleware under the hood. This means you can overlook it and create your own authentication system using middlewares if you want to. However, Robyn still provides this easy to implement solution that should suit most use cases.
After making the application faster, Batman was happy and wanted to make a request from his Frontend Dashboard.
But he was faced with CORS issues! He asked Robyn about how to solve this issue. Robyn told him about the following features
