Question 1

How does NiceGUI compare to Streamlit for dashboards?

Accepted Answer

NiceGUI offers more control over state with less automatic rerendering than Streamlit, making it better for complex interactions but requiring manual state management. It's ideal when you need fine-grained updates without Streamlit's 'magic'.

Question 2

Can I use NiceGUI to build mobile-friendly apps?

Accepted Answer

Yes, NiceGUI uses Quasar which is responsive, but for native mobile features or progressive web apps, additional configuration or complementary tools might be needed.

Question 3

How to add authentication to a NiceGUI app?

Accepted Answer

You can integrate authentication using FastAPI's capabilities, such as OAuth or JWT, but NiceGUI doesn't provide built-in auth components, so it requires manual setup in Python.

Question 4

What's the best way to deploy NiceGUI in production?

Accepted Answer

NiceGUI can be deployed via Docker or as a standalone Uvicorn server; for scalability, you may need to handle session persistence and load balancing, as it uses a single worker by default.

Question 5

How to handle database connections in NiceGUI?

Accepted Answer

Since it's backend-first, you can use any Python database library like SQLAlchemy, but you must manage connections and state within your code, as NiceGUI doesn't abstract this.

Question 6

Is NiceGUI good for real-time data streaming?

Accepted Answer

Yes, with built-in timers and WebSockets, it supports real-time updates, but for high-frequency data (e.g., every 10 ms), test performance to avoid bottlenecks.
