Features

• ⚡️ Vue 3+Vite+pnpm, 怎么快怎么来
• 🔎 TinyGo 追求最小打包体积
• 🔥 wasm 玩的就是wasm
• 🦾 Golang, of course
• ☁️ Deploy on Netlify

• 挂载全局变量

const go = new Go(); // Defined in wasm_exec.js. Don't forget to add this in your index.html.

const importObject = go.importObject;
let wasmModule;

export const InitWasm = async () => {
    wasmModule = await wasmBrowserInstantiate(wasmUrl, importObject);
    go.run(wasmModule.instance);
}

export const ExpressionIt = (s) => {
    let result
    try {
        result = window.expression(s)
    } catch (e) {
        console.log(e)
        result = 'ERROR'
    }
    return result
};

• vue端导入

(async function () {
    await InitWasm().then(() => {
        createApp(App).mount('#app');
    });
})();

• ts支持

export function InitWasm(): Promise<void>;
export function ExpressionIt(s: string): string;
