News & Books is a simple Progressive Web App. It uses Google Books API to search for books and Embedded Viewer API to display book content. It also use the New York Times API as source of news and information and the Unsplash API to get high resolutions pictures related with the key word.

The app is built using PWA Starter Kit. Using the starter-template as the starting point and the wiki for configuring and personalizing.
