Node.js tools: Server-side JavaScript comes of age

Node-inspired development environments and cloud platforms are redefining the Web application stack

The story of Node.js reads like it came from a Hollywood script assembly line: Some kids are monkeying around with scrap they picked up around the Internet and find a new way to snap it together. The next thing you know, they're lapping the pack at the racetrack and coasting to the winner's circle.

In technical terms, the Node.js team, which is largely led by Ryan Dahl, began looking for a new way to serve up documents from a website without chewing up as much RAM as the traditional tools. They grabbed a copy of the V8 JavaScript engine to speed up their code, then created simple libraries that connected the V8 engine to the TCP/IP ports. Presto change-o, it was answering requests very quickly.

Once people noticed the speed, they started actually using the tool and the challenges began. It's easy to make a car by bolting together spare parts that are lying around, but it's an entirely different task to make something that can carry a load or stand up to the daily commute. The first version of Node ran from a command line containing the name of the file where the instructions were stored. That's not a great way to run a big, stable, professional website.

The scruffy, junkyard quality of the Node realm is rapidly disappearing as programmers build extras for Node as quickly as Node itself was born. Now Node is more of an ecosystem, with its own conference and a collection of tools that orbit around it. There are IDEs, deployment tools, and companies looking to offer Node hosting as a service. All are helping to transform Node from science experiment to real contributor in the data center and the cloud.

These tools aren't luxury goods yet. They're largely the first builds, which means there are rough spots and glitches. They are typically small, simple, and far from full-featured solutions, but they're also a chance for the Node users to rethink what did and didn't work with the previous generation of Web tools. Node is addressing some of the problems people have found with the traditional stack and fixing them.

They're also rediscovering some of the reasons why the previous generation of Web developers did many of the things they did. It's a bit of a stretch to say that Node exists because it can be so costly to allocate the RAM to start up a new thread, but the Nodesters are beginning to understand why the last line of programmers created the threads in the first place. There are already a number of angry posts about Node filled with four-letter words because the JavaScript callback paradigm is too unnerving.

To understand a bit of the excitement coming from this corner of the Net, I spent some time unpacking the Node tools and putting them through simple tasks. The more I experimented, the more I found. The area is growing quickly, and this summary is already incomplete as I file it. The good news is that the ground is incredibly fertile. Node.js has revealed that running a website doesn't need to be that complicated. The tools it is spawning may not be perfect yet or ready for everything an enterprise requires, but they're real and they're beginning to play a role.
