A Proxy server is a server that acts as a middle layer when requesting data from a 3rd party API. In building a proxy server, you will create a server that requests data from an external API and serves the user that information.

User <------> Proxy <-----> Internet Domain

So the Proxy receives requests from the internal network (LAN) and forward them to the internet and vice versa.

This application is a simple proxy server that redirects the user to the specified website. Example: localhost:PORT/google will redirect the client to https://google.com

Steps to configure the application:

• Create a directory. In this case, mine is: my-proxy

• Create a new Node project: yarn init -y The "-y" or "--yes" flag means "yes" to all configs, btw it is a default configuration.

• Installing Express dependencies: yarn add express

• Installing "http-proxy-middleware" dependencies: yarn add http-proxy-middleware

• Adding a "start" command to our project:

  ,
  "scripts": {
      "start": "node index.js"
  }
  

This will allow us to run our project with "yarn start".

• Install nodemon for re-running after changes: yarn add nodemon
