Progressive Web Applications are the state of modern web solutions. With the proper strategies, it is possible to drastically improve the overall performance and providing data even without a network connection. 
In an increasingly mobile-first world, optimising the time to load web pages can be our business's success. 

We will start by describing what PWAs are and their advantages over native and plain web applications. We then go deeper analysing fundamental concepts like service workers, caching strategies and when to use them in different scenarios. 

Aside from generic, framework-agnostic code samples, there will be an entire "hands-on" section dedicated to Angular, where we will create a complete, real-world PWA project from scratch.

Finally, we will learn how to deploy our PWAs to the cloud with different providers, describing in detail the approach with the Firebase platform. Thus, concluding our journey in the PWAs world.

## Service worker configuration file
This is one of the essential files added by the `@angular/pwa` schematic because the service worker configuration file (`ngsw-config.json`) allows specifying the different caching strategies for the assets and network responses. 


# Service worker configuration file
This is one of the essential files added by the `@angular/pwa` schematic because the service worker configuration file (`ngsw-config.json`) allows specifying the different caching strategies for the assets and network responses. 


The service worker configuration file provides several properties that allows developers to specify which caching strategies to implement and which resources to target.
