Summary
In this chapter, we learned how to use Node.js as a command-line tool. We successfully got arguments from the terminal, searched directories for image files, and uploaded them to Flickr. Most of the raw operations such as access to the filesystem or the Flickr OAuth implementation were delegated to different modules, which we added as dependencies to the project. More and more instruments are emerging everyday which transform Node.js into an attractive environment to develop not only web-based applications, but also command-line scripts.
In the next chapter, we will learn how to use Node.js and Ember.js together. We will get a Twitter social feed and display it on the browser.
