tsconfig.json

{
  "include":["./src/**/*.ts"],/*源代码存放的路径*/
  "compilerOptions":{

    "target": "ES6",/*编译后的目标语言规范*/
    "removeComments": true,/*编译时是否删除代码中的注释*/
    "outDir": "./public/js",/*输出目录位置*/

}

server.js

'use script'
var http = require("http");
var serveIndex = require('serve-index')
var express = require('express');
var app = express();
app.use(serveIndex('./public'));
app.use(express.static('./public'));
var http_server = http.createServer(app);
http_server.listen(8000,'0.0.0.0');
