What is Node.js?
Why choose Node.js for web development
Event Driven Architecture
It's a family of styles that allow components to communicate through asynchronous messages. Systems based on event-based styles are often organized as a loosely coupled federation of components that trigger behavior in other components through events.
A variety of event styles exist, for example:
Crosscutting concerns are addressed by aspect style.aspect style is a module style, event-based style - runtime style, so it's important not to mix them up.
Real-time web apps? No problem!!
RTA is an application program that functions within a time frame that the user senses as immediate or current. The latency has to be less than a defined value, usually measured in seconds. The use of RTAs in your applications is called the Real Time computing (RTC).
NPM Package Manager:
The main advantage, from the perspective of a developer, is simple: local package installation.
Of course, this approach means that packages may be duplicated on the filesystem, but with the size of most packages vs. the size of current hard drives, that's really not so much of an issue.
When data streaming is the real deal
I/O bound applications are at a greater advantage with the way streams are managed in node.js. Data Streaming is one of the most powerful applications of node.js given that there are very few to choose from. As a majority of the data that come into the systems are in the form of streams, a lot of time can be saved during the process. The ultimate aim is to utilize the time during another operation, and node.js facilitates just that.
