wasmloader

import "github.com/rfwlab/rfw/v2/wasmloader"

WASM loader with progress bar and automatic brotli decompression for Go WASM apps.

Load

func Load(url string, opts Options)

Loads and instantiates a Go WASM bundle. Supports .wasm and .wasm.br (brotli compressed) files.

Options

type Options struct {
    Go         js.Value  // Go runtime instance (required)
    Color      string   // Progress bar color (default: #ff0000)
    Height     string   // Progress bar height (default: 4px)
    Blur      string   // Progress bar blur (default: 8px)
    SkipLoader bool     // Disable progress bar
}

Behavior

1. Tries .wasm.br first, then .wasm
   
2. Shows animated progress bar during load
   
3. Automatically decompresses brotli files
   
4. Calls Go.run(instance) after instantiation
   

Example

import "github.com/rfwlab/rfw/v2/wasmloader"

wasmloader.Load("./app.wasm", wasmloader.Options{
    Go:    js.Global().Get("Go"),
    Color: "#00ff00",
})
