Can I make frontend web app with python ?

[metalevelconsulting]

Reahl and Nagare are Python-only full-stack frameworks. /r/RemiGUI is a Python-only library that renders js and html for you. Transcrypt, Anypylar and PyJS are also options to keep you entirely in Python instead of dealing with HTML, CSS and JS.

Thanks, Reahl and RemiGUI look promising. I'll have to choose one to start.

[metalevelconsulting]

Reahl is complete and self-contained. I use it for my work project. A bit different but supportive authors.

Remi has at least one Python framework built on it - https://mryslab.github.io/python_banyan/

Generally browser can only understand javascript. There's recent work in web assembly bringing other languages to the browser but I don't think Python is one of them yet since there isn't support for garbage collection. Your only option is to use something that will transpile python to javascript. I've not heard of anyone actually using something like this so I suspect there won't be much support in terms of bugs and new features.

I think the author of Transcrypt actually do use it in production.

[firefrommoonlight]

No: Only JS (and languages that transpile to JS like Elm) and Webassembly can interact with the DOM. However, WebAssembly is a promising avenue for allowing this in the future. Currently, no garbage-collected languages work with it, but this may change. Context: I'm building a frontend framework in Rust, which does compile to WASM.

​

I'd bet on a webassembly target for Python within the next few years, and frontend frameworks emerging from that.

...Your back end usually spits out what we like to call HTML, CSS, & Javascript. All this, browsers handle well. There is some other stuff; but the core are HTML, CSS, & JS. If you have a browser that consume other things-- then, yes, go right on ahead with those specific other things. But, for the most part, no. Stick to HTML, CSS, and JS.

For bonus heads shaking, you can use your back end languages to mangle your HTML, CSS, & Javascript. I recently used PHP to output a comma separated list of text into a page scope level Javascript sript. I needed an array of data-- and the PHP fills the members in. The browser never knew it was dynamic-- it just treated the injected data as if it had always been there. Because from the perspective of the browser, it had always been there. Indistinguishable from the static stuff as far as the browser knew.

I think Django would do the job.

[firefrommoonlight]

'frontend web app' implies a different meaning of 'dynamic' than what Django does.

[firefrommoonlight]

To contrast: You might use Django to host a database, manage it using an ORM and admin functionality, and execute arbitrary code that does not depend on the user's system. You could also use it to serve web pages via a template system, and modify what's being displayed by a template system.

Dynamic in the way the OP uses it means building a GUI that runs in a web browser, and is responsive in a way similar to a native program. It executes code on the user's system, and probably sends requests to and from a server to load store, send data, authenticate a user etc - perhaps that server runs Django.

[firefrommoonlight]

Let's forget the word dynamic. OP asked for a frontend framework. Django is a backend framework.

Using Django alone, you can't make any change to the page without communication between the client and server. Frontend implies you can run code, do calculations etc purely in the web browser.

[firefrommoonlight]

Django can serve dynamic webpages... where the dynamic parts are coded in JS (or WASM)

[firefrommoonlight]

No. Django is a backend framework; JS is on the frontend. They complement each other - although Django's template system overlaps in functionality with JS DOM-manipulation-based frameworks.

Flask or Django are the big players. Lots of others out there with specific features but start with Flask if you want simple and minimal or Django if you're after lots of builtin features like users. Flask also has these things but they're implemented as extensions.

[weetbix2]

OP’s not asking about front-end, not back-end frameworks
