Features packages are those packages that add a specific feature to a Frontity project. They need to be defined and configured in the frontity.settings.js file so Frontity can properly use them in the project.
Most of the logic needed for specific features in a Frontity project are delegated in packages. Some of the packages contain essential features like routing and source, so they will be used by most of the projects. Other optional features (like analytics) can be easily implemented through other packages.
This package is in charge of getting data from WordPress and make it accesible from React components.
