Creating the RSS feed reader

The RSS feed reader we will create will let you add feed URLs, view a list of added URLs, and view the content of each feed URL. We will be storing the URLs in HTML5 local storage.

Setting up the project directories and files

In the exercise files of this chapter, you will find two directories: Initial and Final. Final contains the final source code of the application whereas Initial contains the files to help you quickly get started with building the application.

In the Initial directory, you will find app.js, package.json, and a public directory containing files to be served to the frontend. The app.js file will contain backend code. Currently, app.js and package.json contain no code.

We will put our HTML code in public/html/index.html, and in the public/js/index.js file, we will place our frontend JavaScript code, that is, React code.
