Unicorn in PM2 and running programmatically.

[snowy-jaguar]

Hi got a couple questions about Uvicoorn.

I had a look at the deployment tab of the .org website and saw that Uvicoorn can be run from inside a process manager, would process manager 2 work? As that is what I currently use and I am familiar with how it works.

Another question I ahve is about running uvicorn projects programmatically, is uvicorn.run() blocking like asyncio.run()? I would like to be able to run both my asyncio project and my uvicorn project from the same file as they are related but I can't put uvicorn.run() after asyncio.run() as the asyncio project blocks the entire process and never 'completes' (intended behaviour).

I never used pm2 (actually discovered it) so cant say for sure but I dont see any obvious reason why it could not.

Okay, thanks for the response. I'm going to keep this open a bit longer in case anyone else knows anything about uvicorn and pm2 and in case someone is able to provide an answer to my second question.

sorry didn't answered that, one could use the startup events to run your asyncio project. something like this perhaps:

import asyncio

from starlette.applications import Starlette

import uvicorn


async def other_async():
    while True:
        print(1)
        await asyncio.sleep(1)


async def startup():
    task = asyncio.create_task(other_async())


app = Starlette(on_startup=[startup])


if __name__ == "__main__":
    uvicorn.run("two_async:app")
