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.
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.
- 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
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.
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.
