uvicorn VS daphne

This tells Heroku to run uvicorn, which is a web server implementation in Python.

FastAPI uses Uvicorn, an ASGI (Asynchronous Server Gateway Interface) web server implementation for Python.

Now, let’s run our FastAPI application using Uvicorn: uvicorn main:app --reload

Uvicorn + Starlette 8k requests/s

I switched to Hypercorn because Uvicorn currently supports HTTP/1.1 and WebSockets as mentioned at https://www.uvicorn.org

This will set up Chroma and run it as a server with uvicorn, making port 8000 accessible outside the net docker network. The command also mounts a persistent docker volume for Chroma's database, found at chroma/chroma from your project's root.

There's an open discussion under the Uvicorn repository and we prepared a repository for Reproduction GitHub Repo

FastAPI is a popular Python Web framework that developers use to create RESTful APIs. It is based on Pydantic and Python-type hints that assist in the serialization, deserialization, and validation of data. In this tutorial, we will use FastAPI to create a simple "Hello World" application. We test and run the application locally. FastAPI requires a ASGI server to run the application production such as Uvicorn.

Uvicorn and Daphne are both ASGI server implementations that can be used with Django to serve your application using the ASGI protocol. Uvicorn is built on top of the uvloop library, which is a fast implementation of the event loop based on libuv, while Daphne is maintained as part of the Django Channels project and was designed to handle the unique requirements of Django applications that utilize asynchronous features, such as real-time updates, bidirectional communication, and long-lived connections.

I'm trying to implement a real time chat and I took a look at Channel. The documentation mentions that the server needs to be run with Daphne, and Daphne needs an asynchronous version of UWSGI named ASGI.

Daphne

For example, there are the servers: Daphne: https://github.com/django/daphne Uvicorn: https://www.uvicorn.org/ Hypercorn: https://pgjones.gitlab.io/hypercorn/index.html

This. To add between Django and nginx there is a application server that can talk to Django using wsgi and more recently asgi as it’s async compatible protocol. See daphne that implements asgi protocol. If you have trouble understanding you will find much more examples using wsgi with gnuicorn or uwsgi.
