Offline first!

As developers, we usually work on fancy devices with super fast and stable internet connections. It might be a complete shock for you, but most of your users aren’t.

With the incredible power of Service Workers, we can provide a fast and reliable experience for all our users. Forget about Mobile first or Content first; let’s go Offline first!

In this talk, Rowdy will look at different caching strategies to boost the performance of your website and how to deal with offline situations using the Cache API and Fetch API. As a bonus, these techniques will save your users’ valuable bandwidth and battery life as well.
