We Have to Talk About Flask
I've been maintaining my Build a SAAS App with Flask video course[0] for 8 years. It has gone from pre-1.0 to 2.3 and has been recorded twice with tons of incremental updates added over the years to keep things current.
In my opinion tutorial creators should pin their versions so that anyone taking the course or going through the tutorial will have a working version that matches the video or written material.
I'm all for keeping things up to date and do update things every few months but rolling updates don't tend to work well for tutorials because sometimes a minor version requires a code change or covering new concepts. As a tutorial consumer it's frustrating when the content doesn't match the source code unless it's nothing but a version bump.
I've held off upgrading Flask to 3.0 and Python 3.12 due to these open issues with 3rd party dependencies https://github.com/nickjj/docker-flask-example/issues/17.

- Good example projects on Github with Flask and Next.js 13?

Course recommendation for a begineer
Flask Mega Tutorial and "Build a SaaS App" purchased directly from the course website are probably your best bets.
-
How familiar do I need to be with Python to learn Flask?
The resource I'm looking to learn from is u/nickjj_ course, but I'm trying to figure out how familiar I should be with Python before I dive into it. Looks like I may need some HTML/CSS/JS as well.

Show HN: The pure Python SaaS starter kit
Build a SAAS App with Flask. Course / Boilerplate. https://buildasaasappwithflask.com/
- Has anyone taken this course?
-
starter project?
Personally I maintain https://github.com/nickjj/docker-flask-example. There's also https://github.com/nickjj/build-a-saas-app-with-flask if you want more opinions.

Where can I find templates (with or without code) of flask apps/SaaS?
There's: https://github.com/nickjj/build-a-saas-app-with-flask

Using Celery with Flask application factory
If you're looking only for a code reference there's https://github.com/nickjj/build-a-saas-app-with-flask which uses an app factory and Celery. It's all set up to send emails through Celery and has tests too.

How to go about creating a SaaS without experience as a student?
A few years ago I started my programming/ SaaS yourney and now I can live from my solo bootstrapped SaaS. I started learning Python 2 (free) on codecademy. Followed by the free CS50 from Harvard on Edx.org . After that I build my first SaaS using the SaaS template/ course https://buildasaasappwithflask.com

trio VS awaits - a user suggested alternative
2 projects | 9 Dec 2023
-
In what ways are channels are better than the traditional await?
Incidentally, the alternative event loop implementation trio in python does not have "gather", you also need channels, and it's a deliberate design choice - there is some discussion about that in this ticket https://github.com/python-trio/trio/issues/2188

The Heisenbug lurking in your async code (Python)
I'll +1 the Trio shoutout [1], but it's worth emphasizing that the core concept of Trio (nurseries) now exists in the stdlib in the form of task groups [2]. The article mentions this very briefly, but it's easy to miss, and I wouldn't describe it as a solution to this bug, anyways. Rather, it's more of a different way of writing multitasking code, which happens to make this class of bug impossible.

The gotcha of unhandled promise rejections
It's similar to manual memory management.
Structured concurrency is one approach to solving this problem. In a structured concurrency a promise would not go out of scope unhandled. Not sure how you would add APIs for it though.
See Python's trio nurseries idea which uses a python context manager.
https://github.com/python-trio/trio
I'm working on a syntax for state machines and it could be used as a DSL for promises. It looks similar to a bash pipeline but it matches predicates similar to prolog.
In theory you could wire up a tree of structured concurrency with this DSL.

Python Asyncio: The Complete Guide
Not complete - doesn't include Task Groups [1]
In fairness they were only included in asyncio as of Python 3.11, which was released a couple of weeks ago.
These were an idea originally from Trio [2] where they're called "nurseries" instead of "task groups". My view is that you're better off using Trio, or at least anyio [3] which gives a Trio-like interface to asyncio. One particularly nice thing about Trio (and anyio) is that there's no way to spawn background tasks except to use task groups i.e. there's no analogue of asyncio's create_task() function. That is good because it guarantees that no task is ever left accidentally running in the background and no exception left silently uncaught.
