[nodemon] app crashed - waiting for file changes before starting...

const http = require("http");

const PORT = 4999;

const ip = "localhost";

const server = http.createServer((request, response) => {
const { headers, method, url } = request;
// 여기서부터 작성
let body = [];
request
.on("data", (chunk) => {
body.push(chunk);
})
.on("end", () => {
body = Buffer.concat(body).toString();
});

if (request.method === "POST" && request.url === "/upper") {
response.writeHead(200, defaultCorsHeader);
response.end(body.toUpperCase());
} else if (request.method === "POST" && request.url === "/lower") {
response.writeHead(200, defaultCorsHeader);
response.end(body.toLowerCase());
} else if (request.method === "OPTIONS") {
response.writeHead(200, defaultCorsHeader);
response.end();
} else {
response.writeHead(404, defaultCorsHeader);
response.end("Error");
}

console.log(
`http request method is ${request.method}, url is ${request.url}`
);
response.writeHead(200, defaultCorsHeader);
response.end("hello mini-server sprints");
});

server.listen(PORT, ip, () => {
console.log(`http server listen on ${ip}:${PORT}`);
});

const defaultCorsHeader = {

"Access-Control-Allow-Methods": "GET, POST, PUT, DELETE, OPTIONS",
"Access-Control-Allow-Headers": "Content-Type, Accept",
"Access-Control-Max-Age": 10,
