Offline First Web Development

By: Daniel Sauble

Overview of this book

When building mobile apps, it’s easy to forget about the moments when your users lack a good Internet connection. Put your phone in airplane mode, open a few popular apps, and you’ll quickly see how they handle being offline. From Twitter to Pinterest to Apple Maps, some apps might handle being offline better—but very few do it well. A poor offline experience will result in frustrated users who will abandon your app, or worse, turn to your competitor’s apps Expert or novice, this book will teach you everything you need to know about designing and building a rigorous offline app experience. By putting the offline experience first, you’ll have a solid foundation to build upon, avoiding the unnecessary stress and frustration of trying to retrofit offline capabilities into your finished app. This basic principle, designing for the worst-case scenario, could save you countless hours of wasted effort.

Summary


In this chapter, we discussed different ways of dealing with a split-brain: the collective agreement approach where every collaborator must agree on the same resolution and the self-appointed dictator approach where any collaborator can choose a resolution independently of the others. We implemented the second approach for the description field of the to-do items and discussed ways to extend this to the map and image fields as well.

In the next chapter, we'll look at ways to optimize the performance of the app. Up until now, we've stuck with the standard defaults provided by our offline database. Let's investigate where our defaults fall short and how to improve them. We'll also learn how to detect different usage scenarios and tweak the defaults in real time to accommodate these scenarios.
