These resources are then returned to the client as though they originated from the server itself (or servers themselves). While a forward proxy acts as an intermediary for its (usually nearby) associated clients and returns to them resources accessible on the Internet, a reverse proxy acts as an intermediary for its (usually nearby) associated servers and only returns resources provided by those associated servers.
Node.js uses an event-driven, non-blocking model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. This simple web server written in Node responds with “Hello World” for every request. To run the server, put the code into a file example.js and execute it with the node program from the command line.
