In this chapter, we discussed using standard web technologies inside the Electron application. The first section was about using service worker to enable the resource caching and providing the offline experience when accessing remote content. The next part was about implementing the push notification with service worker inside the Electron application. Finally, we checked how we can store the data inside the shell/browser itself using the standard HTML5 APIs. Instead of directly using the low-level API, we used a custom library so that the storage target can be easily migrated. 

The next chapter will cover testing the Electron application. We will also be discussing how to test a web application as the Electron's user interface is built with web technologies.
