WebAssembly Key Encoder Example

This example demonstrates how to use the Ghostty VT library from WebAssembly to encode key events into terminal escape sequences.

Building

First, build the WebAssembly module:

zig build lib-vt -Dtarget=wasm32-freestanding -Doptimize=ReleaseSmall

This will create zig-out/bin/ghostty-vt.wasm.

Important: You must serve this via HTTP, not open it as a file directly. Browsers block loading WASM files from file:// URLs.

From the root of the ghostty repository, serve with a local HTTP server:

# Using Python (recommended)
python3 -m http.server 8000

# Or using Node.js
npx serve .

# Or using PHP
php -S localhost:8000

Then open your browser to:

http://localhost:8000/example/wasm-key-encode/

Focus the text input field and press any key combination to see the encoded output.
