create a http server and read the request body as form url encoded in typescript

You can use the built-in http module in Node.js to create an HTTP server and receive requests. To parse the request body as form-urlencoded, you can use the querystring module.

Here's an example code snippet in TypeScript:

index.ts
import * as http from "http";
import * as querystring from "querystring";

const server = http.createServer((req, res) => {
  if (req.method === "POST") {
    let body = "";
    req.on("data", (chunk) => {
      body += chunk.toString();
    });
    req.on("end", () => {
      const formData = querystring.parse(body);
      // Do something with the form data
      console.log(formData);
      res.end("Form data received");
    });
  } else {
    res.end("Hello, World!");
  }
});

server.listen(8080, () => {
  console.log("Server listening on port 8080");
});

In this example, we create an HTTP server that listens on port 8080. When the server receives a POST request, it reads the request body as a stream and concatenates the chunks into a string. Then, it uses the querystring module to parse the form data into a JavaScript object. Finally, it logs the form data to the console and sends a response to the client.

Note that this example only works for form-urlencoded data. If you need to handle other types of request bodies (such as JSON), you'll need to use a different parser.
