We live in a disconnected world. However this should not adversely affect our experiences when using mobile web applications offline. Using existing HTML5 and JavaScript technologies it is possible to create great offline user experiences that not only make a mobile web application work offline but positively affect the application in terms of speed, reliability and usability.
More specifically we look at the technology that can be used to create offline first web applications, including how to cache pages/assets and how to store data using different browser storage options. We will explore the offline first design pattern and why it is becoming important when building mobile applications.
