Features

Fully Independent (Only needs a web browser or a WebView at runtime)
Lightweight & Small memory footprint
Fast binary communication protocol between WebUI and the browser
Multi-platform & Multi-Browser
Using private profile for safety
Cross-platform WebView

Installation

Install via Nimble:

nimble install webui

Documentation

Online documentation can be found here:

https://webui.me/docs/2.4.0/#/nim_api
https://yesdrx.github.io/nim-webui// (docs in Nim format)

I suggest to get started using some examples or WebUI's own examples or documentation.

Heres a very minimal example of using the wrapper:

import webui

let window = newWindow() # Create a new Window
window.show("<html>Hello</html>") # Show the window with html content

wait() # Wait until the window gets closed

Examples

Examples can be found here at examples/.

If you're trying to run the examples remember to clone the repository recursively, as it depends on the WebUI repo as a submodule. Here's the command to do so for the truly lazy:

git clone --recursive https://github.com/webui-dev/nim-webui.git

Bindings and Wrapper

The Nim library exposes two files: webui.nim and webui/bindings.nim. webui/bindings.nim are low-level bindings for WebUI, generated by c2nim using script generate_bindings.nims. webui.nim is a high-level wrapper for WebUI, using native Nim types and avoiding pointers.

The wrapper and bindings also allow to to control whether or not to statically compile WebUI's C sources into your application, compile with a static library, or to depend on a DLL. Static compilation is the default behavior.

To compile with a static library, pass -d:useWebviewStaticLib or -d:useWebviewStaticLibrary to the Nim compiler. To depend on a DLL, pass -d:useWebviewDll instead. If neither of these flags are passed to the Nim compiler, static compilation will take place instead. Static libraries and DLLs can be found in WebUI's website here.

In addition, you can also enable WebUI's logging via -d:webuiLog but that flag only works for static compilation.
