Transcrypt VS nicegui

This is the primary difference between Pyodide and projects like Transcrypt or Brython: rather than transpiling to JavaScript, you get the real-deal CPython interpreter running client-side in the user's browser. There are a few things that don't work out of the box, since CPython usually runs on a computer and the Browser environment has some unique restrictions (lack of low-level access to networking, for one), but most things do just work.

In the past, I've personally used GWT to transpile Java to JavaScript in order to share some complex code modules that we needed to use on both the server and client for an enterprise application. In more recent years, I've been using Transcrypt to develop React/MUI applications that are coded in Python. So I'm able to use JS libraries that are proven to work great in a web browser, but use my preferred language to code to the API of those libraries. This approach is certainly not for everyone, but it can be a viable option in some cases.

I now use Python everywhere. Desktop (PySide), embedded (MicroPython), web dev (React via Transcrypt), mobile (Kivy), and just general scripting. I love the versatility of Python, the ease of reading it without the visual cruft of other languages, and the availability of existing libraries that do just about everything you can think of. I also agree with the OP on the welcoming attitude of the Python community. The fact that Python is used in so many different areas leads to many new learning experiences when talking to other Python developers.

Transcrypt is pretty usable for this.

Transcrypt transpiles Python into JavaScript in the same way that TypeScript gets transpiled into JavaScript. It lets Python code word with JavaScript libraries that can then be run in a web browser.

There are options for writing Python and transpiling it into JavaScript but, frankly, they suck (https://www.transcrypt.org/).

Lol, I'll tell you but you're not gonna like it - I write React applications in Python using a Python-to-JS transpiler called Transcrypt, and the source needs to be valid lintable Python code, so no JSX.

The Python AST module exists for this purpose and works by tokenizing individual pieces of the source code. It's also how transpilers such as Transcrypt work their magic to convert Python code to other languages.

I was looking at this space and nicegui seemed like the best ootb experience.

Dash is similar in spirit, as a "build web UIs with Python" framework. Dash seems more similar to nicegui (https://nicegui.io) architecturally than to Hyperdiv. Like nicegui, it builds a static dom that is then mutated via callbacks or data bindings.

By contrast, Hyperdiv lays out UI declaratively based on state, and when state changes, the app re-runs, generating an updated UI. Streamlit and Hyperdiv seem to work similarly, though I'm not sure how Streamlit handles state and state-based layout.

For native GUI, DearPyGui[0] as modern as you can.

For browser web-based GUI, you can use nicegui[1]

I want to bring to attention a set of frameworks that make webdevelopment using Python simple and fun. The popular opinion maybe that webpages developed with Python maybe slow. But this is not the case. Do checkout https://github.com/ofjustpy/ofjustpy/, https://github.com/zauberzeug/nicegui/ and https://github.com/justpy-org/justpy . All these frameworks are build on top of Starlette and make web development really easy. If you want simple and ready to use the nicegui is the choice. If you want fast, scalable, and more control then give ofjustpy a try.

Yes, NiceGUI aims for a very gentle learning curve. Coming from Streamlit I suspect your main adaptation will be that in NiceGUI you need to write valid Python code. Streamlit constantly reevaluates your script which feels nice and easy but creates lots of problems down the road. See https://github.com/zauberzeug/nicegui/discussions/21.

Auth is a big limitation. It's not a built-in component, they have [an example](https://github.com/zauberzeug/nicegui/blob/main/examples/aut...) using the FastAPI layer for auth, but I haven't had time the time to try implementing it. It's definitely not something you get out of the box with NiceGUI.

For scaling, I am viewing it mostly as an internal tool builder. I wouldn't recommend it for external applications. So as far as scaling an internal app I think it works fine. [Their website](https://nicegui.io) is built with NiceGUI, and it works fine, but you can feel the lag occasionally on some of their larger demo pages.

Well, I was at PyCon Ireland last weekend and I missed the NiceGUI talk. I hear postive things about it and anything shiney and anything frontend-related always catches my attention (although I admit talking to a friend when I missed this talk was just as fun, and it was worth it).
