新建文件 index.js
const fastify = require('fastify')({ logger: true })
const path = require('path')
// Serve the static assets
fastify.register(require('fastify-static'), {

start()
package.json
{
"scripts": {
"dev": "node index.js"
},
"dependencies": {
"fastify": "^3.6.0",
"fastify-static": "^3.2.1"
}
}

运行 npm run dev 打开http://127.0.0.1:8080
新建 go.mod
module hello-world go 1.18
main.go
package main
import (
"syscall/js"

func main() {
