Project inspiration (outdated examples) - Ditch Javascript Frameworks For Pure Python Joy

Meld is a framework for Flask to meld your frontend and backend code. What does that mean? It means you can enjoy writing dynamic user interfaces in pure Python.

Less context switching. No need to write javascript. More fun!

Issues

Dependency issue

opened on 2022-11-15 10:12:17 by israel-oye

When I install flask-meld, it says flask-meld 0.13.1 requires click==7.1.2, but you have click 8.1.3 which is incompatible because flask-2.2.2 requires click>=8.0

Downgrading Flask does NOT solve the issue either as flask-sqlalchemy-3.0.2 requires flask>=2.2.2

To reproduce: pip install flask-meld pip install flask==2.0.3

Cannot use SQLAlchemy models: "Object of type XYZ is not JSON serializable"

opened on 2022-05-25 13:18:40 by kemaleren

I cannot recreate the search example on https://www.flask-meld.dev/ which shows the function users() running a query and returning the results. Then the template directly uses those objects, such as in <h3>{{ user.name }}</h3>.

When I try to recreate that pattern, I get an exception: TypeError: Object of type XYZ is not JSON serializable, related to line 259 in componenty.py.

I was hoping that since the templates were rendered on the server, I would not need to write a serializer for my models. Is that not correct?

Erroron on load

Updated to the last flask-meld with pip. I have this error on loading of a page using meld component

Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/plain". Strict MIME type checking is enforced for module scripts per HTML spec.

And then I'm not able to have a component working (with a previous version it work)

File uploads

Is there a process to upload files using a component?

Add a diagram of the project layout to guide new users.

Beginning at the following paragraph the README shows new users how to build a minimal app that illustrates what is possible with Flask-Meld:

https://github.com/mikeabrahamsen/Flask-Meld/blob/main/README.md#initialize-meld-in-an-existing-project-alternative-method-to-get-started

A tree showing the project layout would be helpful.
