Many existing tutorials tend to focus on a single technology at a time. In this tutorial we will build two versions of an offline website in order to demonstrate how to add functionality to an existing offline website in such a way that existing users won’t get left behind using an old version.
There are plenty of great resources already written for offline HTML5 websites, but just getting a website to work offline is not enough. Why the world needs another Offline HTML5 App Tutorial I now recommend only implementing IndexedDB integration and using the IndexedDB polyfill to support browsers that only provide WebSQL.įor the actual integration with IndexedDB I recommend using Dexie.js a Promise-based library that makes integrating with IndexedDB easy and safe. Most importantly, my advice on using local databases (WebSQL and IndexedDB) has evolved since writing this article. For more up to date tips and best practise see my offline web app workshop, published for free on GitHub, which includes a chapter on building an offline news app. This article is a little out of date but it still gets a lot of traffic.
