Question 1

How do I pass data from JavaScript to V in V-WebUI?

Accepted Answer

Use the webui.js script in your HTML to call backend functions bound in V, like webui.greet(), and handle arguments with Event.get_arg() in V, as shown in the example code. The binary protocol ensures efficient data transfer.

Question 2

V-WebUI or Electron for a lightweight desktop app?

Accepted Answer

V-WebUI is lighter (~200 Kb, no bundled browser) and dependency-free, ideal for minimal footprint, while Electron includes Chromium with a larger ecosystem but more bloat. Choose based on control over the runtime versus feature richness.

Question 3

Is V-WebUI ready for production use?

Accepted Answer

It's MIT-licensed and stable for cross-platform apps, but consider the WIP documentation and browser dependencies. For critical projects, test thoroughly due to the smaller community compared to mature frameworks.

Question 4

How to debug V-WebUI applications when things go wrong?

Accepted Answer

Compile with the -d webui_log flag for debug builds, as noted in the README, to enable logging. Also, check browser developer tools and refer to the examples directory for common patterns.

Question 5

What browsers does V-WebUI support on macOS?

Accepted Answer

On macOS, it supports Firefox, Chrome, Edge, and others, but Safari is 'coming soon' and not fully available yet, per the compatibility table in the README.

Question 6

Can I use V-WebUI without an internet connection?

Accepted Answer

Yes, it uses local browsers for GUI rendering, so internet isn't required for basic operation. However, ensure browsers are installed locally, and note that some web features might need offline handling.
