I use Django Channels for WebSocket, but I can't find a way to deploy it on Windows. I can't change my platform so switching to Linux is not an option.
Could you please suggest a way to deploy Django Channels on Linux?
Or Do you know what is the Django Channels alternative for Windows?
Django channels also implement with redis server. redis server available on window.
use Django Channel Layer with redis server.
channel layer use web-socket between Django application and socket layer.
please follow this link Channel-Layers

So I have a basic question about WebRTC with Python Django.
Maybe I start at the beginning:
So is it possible that Python Django can serve as a Server for WebRTC? I think in generell it shouldn't be that hard, because how I saw the WebRTC client only needs a Websocket connection. I hope anybody can help me with that. Btw. I use Django Channels, so I think it is possible to build this connection, but how? :)
I would guess they're not recommending it above because it gets complicated very quickly implementing WebRTC video calls on your own with cross-browser support (Safari, especially). Using existing video APIs that have done that work for you can be a great option for a lot of companies to avoid all the edge cases that affect video quality. Daily, Agora, Twilio are all video API options that can handle this work for you.
It's not impossible but I do not recommend!
Instead, there are some WebRTC media servers like Jitsi, AntMedia and Janus. I used the last one on one of our project with Django.
Checkout microservices achitecture and find a way to combine your project with Django (for Authentication, Authorization and other processes) + WebRTC Media Server + Frontend and/or Mobile App. May Frontend could be in same code base with Django, up to you.
I am little bit confused about the main roles of django-channels and uvicorn server. I have read a lot of blogs but did not get much clarification.
If we can implement an ASGI server for websockets using channels, then why do we need asgi server seperately like daphene or uvicorn?
Daphne is a ASGI server while Django Channels is an ASGI Framework for Django.
Links have been taken from www.uvicorn.org.
Also reference from another blog is mentioned below:
Channels was created to support asynchronous protocols like Websockets and long polling HTTP. Django applications still run synchronously. Channels is an official Django project but not part of core Django.
Django Async project will support writing Django applications with asynchronous code in addition to synchronous code. Async is a part of Django core.
Both were led by Andrew Goodwin.
These are independent projects in most cases. You can have a project that uses either or both. For example if you need to support a chat application over web sockets, then you can use Channels without using Django’s ASGI interface. On the other hand if you want to make an async function in a Django view, then you will have to wait for Django’s Async support for views.
I am creating an IoT project with a simple switch on and off event that is sent by the user to Django serve. And my device also connected to the Internet.
Here I want to get data to the device when the user does any action for the device using the Django Rest framework.
Getting data real-time using Django rest framework.
Here the device is raspberry PI.
Is this possible? If yes Please give me any reference.
You can host websockets by yourself with django-channels,or you can use third-party message middleware like pubnub which has python sdk for raspberry PI and java/objects-c sdk for your android/iOS devices.
By the way,i think django and drf is too large for raspberry PI.If your goal is simply to turn light on and off,pubnub is your best choice.
I have done similar project like you,I choose pubnub as message channel.Use android device send command within pubnub to raspberry PI,and raspberry PI control it's GPIO to turn on or off relay.Hope this will help you.
You can use django-websocket-redis package for this purpose
you can directly push messages to UI using this package
Please have a look at this Package
I am writing a Python based application (CLI Back End) which does telnet to some network components and gets some data. It saves the data in SQLite db.
For this application I am writing Django based frond end. Which will start the CLI app and monitor it. For communication between the CLI App and Django I am not able to decide what to use. I read somewhere on net that Django channels can be used in this problem.
I have no idea about what Django channel is and what it does. I need to come up with a tool for this CLI and Django communication.
Is it reliable to build desktop applications using web frameworks like Django?
The idea is to
build the interface with HTML, CSS, and JavaScript
use Python and Django for backend operations (calculations, storage and databases, etc)
and then run a server locally so that
the interaction with the application is done through the browser
other local devices can access the application by connecting to the device on which the server is running.
If that is possible and yields a reliable experience, then
is the development server that comes with Django enough? If no, what servers are most suitable for our purpose? Is Nginx good for example?
what database should be used? PostgreSQL, MySQL, etc? The app will need to store a large number of entries.
I've never done this, but I can't see why not. You can use the Django REST Framework to create an API that your desktop application can talk to, in exactly the same way as you might with a JavaScript single page app.
But no, you should not use the dev server for production, even in a limited scenario like this. Apache/mod_wsgi or nginx/gunicorn are simple to set up and deploy.
For the database, it makes no difference. The Django core devs prefer postgres, but you should use whatever you are comfortable with.
You are asking for a webApp, so yes you can. Is not use the Django server, instead is very common use nginx for Django, and the best database is postgres for Django.
If you want to pass your project like a desktop app is better use Django server and SQLite for avoid create a new database server.
Database
I find this answer explaining why is postgres better for Django
