express-reverse-proxy

Implementation of reverse proxy with Nodejs / Express. Created to handle HTTP verbs and mantain parameters and request headers.

The main objetive is skip CORS in request, useful in secure knowed servers.

Usage

This module require Express in your main implementation. This module returns an Express Router, for your express implementation.

// Typical express declaration...

var RouterAP = require("express-reverse-api-proxy");

// Other Express middlewares and routes...

app.use("/api_proxy_endpoint", RouterAP);

Every request to endpoint REQUIRE this header:

• x-ap-host -> String with URL of destiny

And REQUIRE an middleware conversion to string, same as next:

const express = require("express");
const app = express();

// Other express declarations and middleware

app.use((req, res, next) => {
  var data = "";
  req.setEncoding("utf8");
  req.on("data", (chunk) => {
    data += chunk;
  });

  req.on("end", () => {
    req.rawBody = data; // Attaching special property rawBody. Is a string of request.
    next();
  });
});

This middleware allows data to be passed to the server without unnecesary conversions.

The response is the same response of original service. test it in Postman or other request tester.
