- We will also need the ability to test…our HTTP applications.…The SuperTest module is a popular choice…for testing HTTP applications,…such as Express sites.…Let's go ahead and navigate to our Exercise Files…and in chapter 10, lesson eight…under the start folder we now have our ski dictionary app…that we built back in chapter eight.…Let's go ahead and navigate to our Terminal…and the first thing that we want to do…is an npm install…to install the dependencies for this app.…And if you would like to familiarize yourself with the app…we can actually run it, node app,…and we have an Express app running on port 3000,…so I'm going to go to my browser window…and navigate to localhost:3000.…

Alex Banks shows how to install Node.js on a Mac or PC and work with the Node.js core: the global object, event loop, http module, and file system. Then he covers reading and writing data, streaming data, making http requests, and working with the node package manager (npm). In the final chapters, he shows how to start sessions on web servers, communicate with web servers and clients with WebSockets, use the Express framework to develop applications, and test and debug Node.js code.
