If you haven’t heard, LinkedIn released a new iPad app this week. The company’s developers have been writing blog posts about the technology behind the app, and many in the development community are intrigued to read the details. It turns out approximately 95% of the iPad app is HTML with nearly all of the view rendering done on the client in JavaScript.
LinkedIn is the second company to make this many headlines with their mobile app; FT featured heavily in the mobile news when it decided to drop their wildly-popular iOS apps last year in favor of web apps. There’s a great debate going on among mobile developers about native vs. web, and LinkedIn’s efforts are making this conversation even more interesting.
What’s perhaps most interesting of all: LinkedIn is using Node.js, some clever DOM manipulation, and a handful of HTML5-related technologies (localStorage and WebSockets) to make this app incredibly fast.
