Proxyapi Nodejs (Upload of files)

Question

Good afternoon, I am creating a Proxy for an application. What is intended is to centralize a set of API’s and forward requests.

I’m doing a basic example in nodejs. Where I have 2 servers:

• Server 1 (Proxy Server)
• Server 2 (Other API)

Index:

const http = require("http");

const appServer1 = require("./server1");
const appServer2 = require("./server2");

const server1 = http.createServer(appServer1);
const server2 = http.createServer(appServer2);

server1.listen(3001);
server2.listen(3002);

Server 1:

const express = require("express");
const bodyParser = require("body-parser");

const app = express();
app.use(bodyParser.json());

app.post("/upload", function(req, res) {
  res.json({});
});

module.exports = app;

Server 2:

const express = require("express");
const bodyParser = require("body-parser");

const app = express();
app.use(bodyParser.json());

app.post("/uploadOther", function(req, res) {
  res.json({});
});

module.exports = app;

What I wanted to do was forward for example the request http://localhost:3001/upload for http://localhost:3002/uploadOther, without having to save the file for example. Someone can help me?
