NiceGUI 1.2 – Bringing Electron-like Capabilities to Python with pywebview

We are thrilled to introduce NiceGUI 1.2, a major update to our open-source Python library (https://nicegui.io). With an emphasis on simplicity and ease of use, NiceGUI empowers Python developers to create user-friendly graphical web-based interfaces while focusing on their Python code. The library has been well-received, boasting 3000+ stars on GitHub and a growing community.

Lately we've introduced the "native" mode, which paves the way for Electron-like capabilities. By using "ui.run(native=True)", you can now create a native desktop window using pywebview, offering desktop-feeling on Windows, Mac, and Linux.

Technical details:

NiceGUI uses FastAPI in the backend and Vue3/Quasar in the frontend

Each user interaction is sent via WebSocket to the backend, processed in Python; similarly, UI descriptions are created as JSON objects in the backend and sent via WebSocket to the client

While there are still many features missing for a full Electron alternative, with the great community, we will flesh this out in the future

The whole backend-first approach from NiceGUI relies on a fast internet connection and therefore is not meant to replace classical web apps; its main purpose is a quick way to build user interfaces for your Python code

We know the Hacker News community values technical details, and we invite you to dive into the GitHub repository (https://github.com/zauberzeug/nicegui/) to explore the code and contribute. We're eager to receive constructive feedback and improve the library based on your insights.

Join our Discord server (https://discord.gg/TEpFeAaF4f) and subreddit (r/NiceGUI) for discussions, support, and sharing projects.

We appreciate your support and look forward to seeing NiceGUI's potential unfold with your help. Together, let's make NiceGUI the Electron of Python!
