LinkedIn, Node.js, and the Rise of JavaScript in Mobile

If you’re a business professional, you are likely a LinkedIn user. The company recently announced that there are more than 300 million registered LinkedIn users worldwide as of April 2014, which is nearly the entire population of the United States! And increasingly these users are interacting through mobile devices—up to 50% of interactions will be via mobile by end of 2014 predicts LinkedIn. So how does LinkedIn create a mobile app experience that satisfies this very busy and demanding population?

In my recent research note “Improve Mobile App Development and Integration With JavaScript Technologies” I highlight LinkedIn as a case study in how they have evolved their mobile client strategy, from only mobile Web before 2011, to hybrid mobile apps from 2011-213, and finally shifting to full native apps on iOS and Android in 2013. While at the same time, on the server side they swapped out their Ruby on Rails server architecture and implemented Node.js, which gave them substantial performance and scalability increases and agility to address the integration needs of a changing client-side strategy.

In recent years, JavaScript-related technologies like Node.js and various JavaScript frameworks have really gained a foothold in mobile projects. My note explores the implications for mobile strategists in how they should evaluate and support such technologies for both frontend and backend mobile app development, and in planning for the skill set makeup of their mobile development teams.
