Migration from uvicorn to Granian (Python)

[itsmeadarsh2008]

Here is the code snippet. There is no certain documentation of how we could implement it programmatically.

from __future__ import annotations

import multiprocessing
import socket
from typing import List, Optional

import uvicorn

from . import core, storage
from .native import native


class CustomServerConfig(uvicorn.Config):
    storage_secret: Optional[str] = None
    method_queue: Optional[multiprocessing.Queue] = None
    response_queue: Optional[multiprocessing.Queue] = None


class Server(uvicorn.Server):
    instance: Server

    @classmethod
    def create_singleton(cls, config: CustomServerConfig) -> None:
        """Create a singleton instance of the server."""
        cls.instance = cls(config=config)

    def run(self, sockets: Optional[List[socket.socket]] = None) -> None:
        self.instance = self
        assert isinstance(self.config, CustomServerConfig)
        if self.config.method_queue is not None and self.config.response_queue is not None:
            core.app.native.main_window = native.WindowProxy()
            native.method_queue = self.config.method_queue
            native.response_queue = self.config.response_queue

        storage.set_storage_secret(self.config.storage_secret)
        super().run(sockets=sockets)

The main point is to replace uvicorn and speed up the performance. You could give related snippets of code or classes available to figure it out. (I'll be thankful for that)

This would require more information, as I'm not sure why you need a singleton and use uvicorn configuration to manage application-related code.

If you're looking into a way to run Granian in a thread using a single worker, you can check #209. But again, I'm not sure what's the use-case here.
