hello node

nodeのtypeを入れておく。

npm install @types/node

import * as http from "http"



let server:http.Server = http.createServer((req:http.IncomingMessage, res:http.ServerResponse) => {
    res.writeHead(200, {'Content-Type':'text/plain'});
    res.write("Hello World!");
    res.end();
});


server.listen(3001);

console.log("Server start at http://localhost:3001/");

これでlocalhost:3001でhello worldできる。
