Two-Thirds

Two-thirds of Americans access the Web through mobile devices, according to Engine Yard research.

And 34 percent of the world’s top 100 Websites are using HTML5.

Engine Yard says the growth of mobile plus the popularity of HTML5 equals the rise of the real-time Web. And the real-time Web requires real-time technology, such as Node.js.

Node.js is a development framework that uses an event-driven, non-blocking I/O.

Node.js is built on JavaScript to unify front-end and server-side architectures.

Node.js is ideal for high-performance, highly scalable, distributed real-time Web applications.

Node.js is the second-most-watched repository on the GitHub Web-based hosting service-second only to Bootstrap.

Node.js is more watched than Ruby on Rails on GitHub. Bootstrap is first, Node.js second, jQuery third and Rails fourth.

Node Package Manager or NPM is a package manager and distribution system for Node.js. NPM has 12,000 modules and 3,800 active package authors.

LinkedIn is a prominent user of Node.js. On the server side, LinkedIn’s entire mobile software stack is completely built in Node.js. The company went from running 15 servers with 15 instances on each physical machine to just four instances that can handle two times the traffic.

Walmart re-engineered its mobile app to be powered by Node.js and pushed all its JavaScript processing to the server.

eBay recently launched ql.io, a gateway for HTTP APIs, using Node.js as the runtime stack. eBay was able to tune a regular quality Ubuntu workstation to handle more than 120,000 active connections per Node.js process with each connection consuming about 2K of memory.

Node.js is a good choice for building networked multiplayer games, interactive Websites and tools, Web analytics and online chat systems.

It’s JavaScript, the language of the Web.

It supports code reuse at every level: browser, server side and database.

It has a strong, passionate community.

It offers performance and scalability.

It leads to developer happiness.
