While not the most amusingly named feature of the web platform, everything seems to point at ServiceWorker being the most significant addition to the web platform since the introduction of AJAX – over 10 years ago. Not to be confused with WebWorker (used to offload intense compute operations onto another execution thread), ServiceWorker allows you to intercept (and hijack) network requests originating from your site before they’re even dispatched. This article explores how it works, what it means and what it enables, and how you can implement it by following a case study.

When AppCache arrived on the scene it gave us a couple of patterns to make content work offline. If those were the patterns you needed, congratulations, you won the AppCache lottery (the jackpot remains unclaimed), but the rest of us were left huddled in a corner rocking back & forth.

Static Web Applications run independently of the need for server-side dynamic processing. Static web architecture eases common web development headaches without introducing additional complexity. This guide will introduce you to the world of static web applications and offer solutions to common challenges encountered while building them. Welcome!

localForage is a handy library that improves the offline experience of your web app by using asynchronous storage (via IndexedDB or WebSQL where available) but with a simple, localStorage-like API. localForage includes a localStorage-backed fallback store for browsers with no IndexedDB or WebSQL support. This means that asynchronous storage is available in Chrome, Firefox, and Safari (including Safari Mobile).

We want to enable you to build complete web apps in days, without having to worry about backends, databases or servers, all with an open-source library that's as simple to use as jQuery. That's why we're making Hoodie. Hoodie is a noBackend architecture for frontend-only web apps.

Offline.js is a library to automatically alert your users when they've lost internet connectivity, like Gmail. It captures AJAX requests which were made while the connection was down, and remakes them when it's back up, so your app reacts perfectly. It has a number of beautiful themes and requires no configuration.

Needless to say, the native apps fared better and more gracefully degraded when no internet connection was available. Offline is a feature and it’s crucial we start to consider it from the start of a project as apposed to adding support later in the development lifecycle.

HTML5 introduces new methods for enabling a web site or web application to function without a network connection. When you’re working on a mobile connection and your signal drops, or you just have no connection to the internet for whatever reason, having some level of access is better than nothing. In this article, we’ll look at how the application cache can store resources to be used by the browser when it’s offline, granting your users partial access to your web site or application.

Web apps that work offline are still uncommon, and there aren't a lot of "real life" implementation examples on the Web.

ByLine is an IPhone application which synchronises Google Reader and your IPhone, letting you read your last feed entries right from the IPhone - even offline. I am going to test it!
