Flask VS Tornado

I was looking at all the big projects like numpy, pytorch, flask, etc.

I may use Flask-Admin initially to offload the "CRUD" operations to have an initial prototype fast but then drop it ASAP because I don't want to write a "flask-admin application" to fight against later on. If the application is mainly "CRUD", then Flask-Admin is suitable.

Now...

Would you do a breakdown/list of all the jobs you've done by sector/vertical and by function/role and by application functionality?

In the lab to follow, we will be setting up an end-to-end DevOps workflow for a Flask microservice with GitHub Actions, using a self-managed custom runner for maximal control over the pipeline execution environment and automating deployments to a local Kubernetes cluster. Furthermore, we will construct separate pipelines for our "development" and "production" environments to further elaborate on the concepts of continuous deployment and delivery.

Flask Micro web Framework: You will use Flask to build a Flask web application.

In an earlier post I mentioned a bunch of Open Source web applications. Let's now focus on the ones written in Python using Flask the light-weight web framework.

I also suggest that once you've gained familiarity with the basics, you look at micro-frameworks, such as FastAPI and flask, before switching to a full fat framework like django, which will give you an appreciation of what opinionated frameworks such as django can do for you.

I am not expert in these but I thought Tornado's ioloop was readable enough for me to learn more event loops. Mostly, it was being implemented in pure Python.

(Had to be in 4.5 because the newer versions 5.x and 6.x, it's switched to Python's stdlib asyncio)

I am a bit confused, Tornado is web server like a apache http server, or a framework like django, or both?

For Python, I use Tornado.

tornado? this https://github.com/tornadoweb/tornado ?

I'm writing a Node app that talks to a server that uses Tornado, a Python networking framework. The server uses WebSocket and structured JSON to expose RPCs, like sign_on called with the following message:

I've been using Python's Tornado (http://www.tornadoweb.org/) for years now.

Now on version 6, it's fast, well maintained, mature, and has good docs with readable code.

@bdarnell has done an excellent job maintaining it.

Here's one example:

Tornado supported async style co-routines before asyncio was a thing. Now it uses asyncio under the hood by default -- and it did so with an exceptionally smooth transition.

Tornado is another micro framework aimed at a specific use case: asynchronous networking applications. Tornado is well-suited for creating services that open a great many network connections and keep them alive that is, anything involving WebSockets or long polling. Moreover, It requires Python 3.5 or higher and drops Python 2 support entirely.

How to fix tornado.util.TimeoutError: Operation timed out after 5 seconds on tornado test debug?

Here's an official demo chat app using websocket: https://github.com/tornadoweb/tornado/tree/master/demos/websocket, though you should read the docs on websocket for understanding the code.
