js and Yarn , which are available on Mac, Windows, and Linux distributions. Create the simple Node.js proxy In a few easy steps, we'll create a simple proxy in Node.js that can forward requests to multiple different servers/endpoints! The full code – which will be implemented step by step – is available on GitHub here . Initialize the project Let's start by starting a new Node project: Bash Copy the code yarn init This generates a package.json file that contains a basic project configuration. The command displays several questions (name, version, description, etc.) for you.
You can select "Enter" for all questions to accept the defaults (for example, the telegram philippines girl entry point is index.js by default). Install dependencies We need a few packages for the proxy to work: express : minimalist web framework http-proxy-middleware : simple proxy framework (Optional) morgan : HTTP request logger middleware which we can install by running: Bash Copy the code yarn add express http-proxy-middleware morgan Set a boot order We need to add a start command to our project. After a small modification, your package.json file looks like this (depending on when you install these packages, some version numbers may differ, but their core functionality should remain the same.
If the behavior is radically different, check the latest documentation): Json Copy the code { "name": "simple-nodejs-proxy", "version": "1.0.0", "main": "index.js", "license": "MIT", "dependencies": { "express": "^4.17.1", "http-proxy-middleware": "^1.0.5", "morgan": "^1.10.0" }, "scripts": { "start": "node index.js" } } If we now add an empty index.js file , we can run the project via: Bash Copy the code yarn start This should execute the file. Since the file is empty, the console output should also be empty. But enough configurations. Let's use the proxy to make some requests! Create a simple proxy This is where the interesting stuff starts.
Open the index.js file and add the necessary imports: JavaScript Copy the code const express = require('express'); const morgan = require("morgan"); const { createProxyMiddleware } = require('http-proxy-middleware'); Now we can create a basic express server and define some constants that we will use later: JavaScript Copy the code // Create Express Server const app = express(); // Configuration const PORT = 3000; const HOST = "localhost"; const API_SERVICE_URL = Before implementing the proxy logic, we can add the morgan middleware which logs incoming requests: JavaScript Copy the code // Logging app.use(morgan('dev')); To be able to test that we are only proxying what we want, let's add a dummy /info endpoint that doesn't forward the request, but instead returns a simple text response: JavaScript Copy the code // Info GET endpoint app.
