How the Node.js framework builds and delivers scalable architecture

Node.js is designed for server-side scripting as a solution to enterprise problems. In this article, Ankit Gupta explains why Node.js is a great framework for all your scalable architecture needs.

Node.js is an ambidextrous server side application development platform which provides solutions to critical business problems. Managing thousands of clients on a single platform; streamlining I/O operations by resolving the bottlenecks; resolving failures, and achieving business rules are some of the development operations possible with this innovative platform. It is good to know about its basic features to make the most of its asynchronous nature and design patterns.

Node.js features

In many ways, node.js answered the needs of computational forces in quest of frolicsome user experience blended with powerful options to take care of the evolving WWW needs. The framework has won many plaudits for the technical prowess and revolutionary web development concepts. Node.js uses the JavaScript language to wholeheartedly support applications development. That’s why creating single language application stacks and sharing codes between server and the client becomes easy.

Another incredible feature of node.js is its single threaded asynchronous architecture. This enhances the scalability and performance of applications. There is also no need for mutexes, threads, and synchronization in node.js. The asynchronous architecture uses queues, events and causality features for developing applications.

NPM is also known as the Node.js Package Manager oversees the module database. It promotes the concepts like extreme modularity, simplicity, and pragmatism. These features help node in distinguishing itself from other server side platforms.

The World Wide Web (WWW) has registered a voluminous growth in terms of complexity and number of applications. Accordingly, many problems associated with the conventional methods have also surfaced. Node.js is a transcendent framework that has revised the conventional methods of application development. A lot of confusion prevails in the conventional application development processes because of the resurrecting errors and resolutions. When an application progresses, the information expands in two forms after every client connects: volume and shape. The dramatic expansion of information severely overburdens the project team. Hence, the development process becomes difficult and delivers dangerously unpredictable results.

With simple and pragmatic approaches, Node.js differentiates itself from the conventional web process. Instead of multiple threads, node uses only single thread which is committed to the event loop. The call-backs manage the deferred tasks and operations. Moreover, there are options in nodejs to manage I/O operations, concurrency, dependencies, and libraries. So everything is well defined and harmoniously managed.

Node.js and JavaScript

Ryan Dahl, the maker of node.js wanted a modern programming language without streams, filesystem, binary objects, etc. The inventor of this tool realized that JavaScript too has an asynchronous and event-driven design. Therefore, Dahl selected JavaScript for covering the following node requirements:

  • A program running on one thread with one even loop
  • For supporting the extensive I/O operations
  • Smooth programming flow through asynchronous callbacks
  • Dismantling parallel process
  • Assembling simpler programs to form complex programs

Besides having a complex architecture, the Node.js development philosophy believes in seamless operations with fewer blockades. It ensures a perfect equilibrium between high concurrency and optimum utilization of resources. The environment created by node.js and JavaScript is the best fit for creating smaller yet simpler modules. With the advent of ES6 Harmony (latest JavaScript version), the JavaScript has become even more powerful.

Both JavaScript and Node complement each other very well. Node contributes many new functionalities to JavaScript. These functionalities in return provide evented I/O libraries that are helpful in creating powerful system commands. The Node based JavaScript extensions emit events through events EventEmitter. It works like a full-blown toolkit for developing rollicking interfaces.

The ‘rule of modularity’ in node.js development strictly believes that programs should be an aggregate of simple and flexible modules to deal with the evolving business needs. This simplifies the complex debugging process as well. Similar management theory is also prevalent in many manufacturing processes as well. Certainly, In node.js, the programs cover a smaller surface area. In other words, the applications are smaller in terms of size and scope. This is similar to the ‘Keep it Simple Stupid (KISS)’ concept.

In conclusion

The Node.js consulting tool is simple and at the same time amazingly lightweight. It supports caching of modules, RESTful services, and unit testing. Node carries APIs to create a range of servers, i.e. HTTP, DNS, TCP, etc.

Node.js suffers from minor criticism like not supporting multi-threaded programming and heavy duty operations. Whenever a user executes a large number of tasks, then node takes time while executing them one after the other. So kindly exercise caution if you are also looking for Node.js development services to cover your business needs. Only Expert developers with technical aptitude know how to circumvent the challenges associated with it.
