usage

go wasm

func main() {
	wait := make(chan struct{}, 0)
  // 统一挂载在同一个全局变量
	js.Global().Get("__axe__").Set("stringMd5", js.FuncOf(StringMd5))
	js.Global().Get("__axe__").Set("uint8ArrayMd5", js.FuncOf(Uint8ArrayMd5))
	<-wait
}

func StringMd5(this js.Value, p []js.Value) interface{} {
	txt := p[0].String()
	sum := md5.Sum([]byte(txt))
	return hex.EncodeToString(sum[:])
}

func Uint8ArrayMd5(this js.Value, p []js.Value) interface{} {
	startTime := time.Now()
	buffer := make([]byte, p[0].Length())
	js.CopyBytesToGo(buffer, p[0])

	sum := md5.Sum(buffer)
	md5 := hex.EncodeToString(sum[:])

	endTime := time.Now()
	duration := endTime.Sub(startTime)
	fmt.Printf("时间差：%v\n", duration)
	return md5
}

js 调用

import { getAbility } from 'tinygo-wasm-driver';
// 将 go wasm 打包成图片
import wasm from './module.png';
import { useEffect } from 'react';

async function run() {
  const { stringMd5 } = await getAbility('__axe__', wasm);
  console.log(stringMd5('abc'));
}

api

type getAbility = (globalName: string, wasmPath: string): Promise<any>

• globalName: go 中设置挂载的全局变量
• wasmPath: 打包的 wasm 文件，建议打包成 png 图片
