Of Widgets and Apps

One of the primary advantages of Apple's approach to widget engine implementation was that their engine (Dashboard) was based on HTML, CSS, and Javascript, which appeals to a wider spectrum of web developers out there.

Widgets - the idea itself - is nothing new. They were thought up long ago as mini applications with very specific purposes. For example, one such widget might deal with displaying a typical six-day weather forecast. Dashboard's offerings included widgets such as Weather, Stocks, Clock, and Calculator.

A couple years later, when the iPhone debuted, there was apparently news that these same aforementioned widgets' iPhone app counterparts were originally written in a manner similar to the HTML/CSS/Javascript-based Dashboard widgets, but that within the six months between announcement and release, they were redone natively in Objective-C for performance.

But Javascript performance has improved remarkably in the few years since then, with the improvements in Javascript engines from Safari to Chrome to Firefox, and while Apple's stance on native webapps was put aside for the timebeing with the release of the SDK, the webapp idea still lives on in various online and offline forms in Palm webOS apps, Chrome OS apps, and even iPhone MobileSafari's webapps. And it will be interesting to see how further performance improvements increase the viability of the webapp, and by extension, expand development opportunities to a massive number of eager web developers out there.
