Can you use HTML5 technologies to build a website which works offline? Without a reliable internet connection, or no connection at all over a couple of days? We will talk you through the challenges we faced building an offline-first web application, using AppCache, IndexedDB and File API to store the application’s sources and its data in the browser. The questions we had to ask ourselves included: – Is the client or the server the master of the data? – What happens if we introduce schema changes that break out-of-date clients? – How do we handle updates of the application? – How do we sync the data between clients and server? – And what does “offline” mean anyway?
