Tell HN: Flask and Quart have now partially merged

20 pointsby pgjones3 anni fa7 comments

Flask is a web microframework built to be used with WSGI servers and synchronous code. Quart is the same web microframework built to be used with ASGI servers and asynchronous code. In other words Flask and Quart are now the same base framework as they share the majority of their codebases.

This means that you can use the same framework API and understanding to write synchronous code with Flask, and asynchronous code with Quart.

It is important to note that Flask cannot be made asynchronous without breaking extension and backwards compatibility, or without using monkeypatching. Therefore, Quart is best viewed as a namespace for async/await usages.

Questions and comments very welcome. (I'm struggling a little thinking about how best to communicate this)

TIL about the new Flask logo!

There are new logos for all the Pallets projects and Pallets itself, based on a common theme.

Is there are any reason to pick Flask over FastAPI for a new project in 2023?

pgjones3 anni fa

Yes, I've written about this comparison in detail https://pgjones.dev/blog/fastapi-flask-quart-2022/.

Flask definitely wins the documentation and maintenance department. FastAPI has "shiny" docs. Flask at least has an API reference.

Yes, I don't get it when people praise FastAPI's docs - they're more like tutorials and examples rather than documentation.

So I can use Quart part for my API service, and Flask for my UI service all in the same project structure?
