Express.js is a powerful platform for web application development on the Node.js ecosystem.  By providing a flexible set of functions and structure, while still keeping the platform flexible for full control of web request and response flow, Express.js has grown to become one of the most popular extensions for Node.js web development.

The program components of Express.js are request processing, response processing, and templating.  Request processing takes the incoming request HTTP and separates the key components into relevant variables for web development.  The request type, URL, querystring, form variables, can all be extracted and processed to route the request to the proper subsystem.  Inside the subsystem, the program will then generate the response that is sent back to the client.

Express.js responses can consist of both HTML and JSON or XML for AJAX (Asynchronous JavaScript) from the client-side.  HTML page responses are the traditional purvey of web applications, while newer technologies like Angular.js enable client-side pages to perform direct requests to the server, improving performance and increasing the interactivity of web apps.  The response is where the third technology – templating, comes into play in Express.js.  The templating engine helps automate generation of the response, and allow variable insertion directly into the text.  Instead of manually generating the response as a text string, templating enables the response to be generated from existing files, such as EJS or Jade templates, with variable insertion of dynamic data.  EJS makes it easy to insert additional JavaScript processing into the template, emulating the functionality of server-side scripting languages such as PHP.
