Web Hosting Using Nodejs and Express

Nodejs and Express are two of the most widely used platforms for creating server-side web apps, offering extensive support through add-on libraries, technical communities and developers. Their popularity indicates a framework’s likelihood to continue its evolution over time with additional documentation, documentation support and developer/production assistance available as resources.

Express is flexible when it comes to how applications should be constructed, allowing developers to insert middleware functions at any point during request processing chain. Middleware functions can do almost anything imaginable including adding functionality or altering how requests are processed and returning responses back to clients; changing environments; passing control on; even handling errors (although the default behavior of Middleware should log the error). Express also supports several template engines which are commonly used to generate output documents in HTML form.

Third-party middleware can help simplify common Express applications tasks such as working with cookies and sessions, user authentication, accessing POST/GET data, and logging. There are a number of express-compatible third party middleware packages maintained by the Express team that are accessible through npm package manager; these include packages for logging, routing, session management and more.
