Dependency injection is a great pattern for avoiding hardcoded dependencies for components. In this recipe, we are going to examine how we can use a service worker to development and production environments by passing in two injectors to our components without hardcoding the dependencies.
To get started with service workers, you will need to have the service worker experiment feature turned on in your browser settings. If you have not done this yet, refer to the first recipe of Chapter 1, Learning Service Worker Basics: Setting up service workers. Service workers only run across HTTPS. To find out how to set up a development environment to support this feature, refer to the following recipes: Setting up GitHub pages for SSL, Setting up SSL for Windows, and Setting up SSL for Mac.
