If you are developing a software application, its efficiency depends on the back-end framework which you are using. If you are using Node.js, it opens many advantages as well as many ways to improve the performance of the application. But first, know about Node.js and its importance in brief.

Node.js is the most popular back-end development technology which is initially written by Ryan Dahl. The technology has been built with the use of JavaScript, C, and C++ programming languages. Node.js application is runnable on such operating systems including Windows OS, OS X, and Linux OS. Later, this technology has been used by the most popular companies like Uber, Netflix, Groupon, and many more.

Node.js is the open-source Backend Framework that provides a cross-platform run-time environment across all operating systems. This will allow the execution of JavaScript code outside of the browser. The reason behind the development of Node.js is to design and build network applications that are scalable. Node.js enables developers to use the in-built JavaScript library and also to build APIs for the back end. It is more challenging for developers to use Node.js than other technologies. Let’s have a glance at the most important criteria related to Node.js.

How to Improve Node.js Application’s Performance?

Node.js environment is built for the development of fast and scalable software applications. The Node.js web application development platform enables many ways for developers to optimize the applications. Below are the most useful tips to improve the performance of Node.js applications:

1) Clear Cache Memory

Caching is the most crucial factor which affects the performance of any application. Clearing the cache memory of the application will help to respond to a user’s query quickly. To implement the caching in Node.js, use the ‘node-cache’ package. This package will help Node developers to initiate caching to improve the performance of any web application.

2) Eliminate Render-blocking Resources

At the core of the Node.js framework, JavaScript is there! The render-blocking resources are the unused resources in the programming of the application. This portion of code can be CSS or JavaScript. To eliminate these resources from Node.js, make use of defer and async attributes, remove unused CSS and JavaScript files, and do not use CSS with or within the @import rule. For the conditional CSS, allow the use of media attributes in the development of the Node.js Application.

3) Accurately Monitoring Application

During and the after the launching of the app, opt for the monitoring of the product. There are many tools are helps to monitor the Node.js application such as AppMetrics, PM2, Clinic.js, and many more. Real-time data analysis, finding and fixing bugs, the utilization of resources, and other factors must be at the core to monitor the application.

4) Make Use of the Cluster Module

The cluster module is the built-in Node.js which helps developers to take advantage of the all cores available in your system. The use of cluster modules will help in improving the performance of the software app. The cluster module allows running multiple cores to handle the single core or application loading. Allow cluster manager to manage your multiple Node servers, core, or application to maintain the single app. This way, the cluster module helps improve the app’s performance.

5) Avoid Memory Leaks

Memory leaks can lead to vulnerability in the application which results in the reliability issue. It probably happens that the unused memory is not returned to the OS, because of the restrictions. The system of collecting automatic memory is available in Node.js. It is required to keep a sharp eye to avoid memory leaks, as it can also be a reason for data breaches in the application.

6) Use WebSocket for Server Communication

Significant changes can be brought in the Node.js application using the Web Socket protocol. The use of the web socket protocol allows communication between server and client, decreasing the latency. It will also work well on data transferring, initiation of the data, and data storage. The protocol is perfect for data exchange as it provides a speed of 2 bytes per frame. While using the HTTP protocol, it is 8 KB per frame.

Advantages of Using Node.js Backend Framework

The architecture of Node.js development is designed and built in a way to execute programming code and communicate with the operating systems. As the server-side application development platform, which enables Node.js developers to achieve the maximum benefits. Let’s uncover the major advantages of using Node.js in software application development.

1) Fastest Software Development

Node.js uses an asynchronous and event-driven I/O model which is used to perform time-saving operations. It cuts the time for developers while deploying an application. Node.js offers a lightweight runtime environment for the fastest delivery of any software application. With the use of the Node.js development framework, developers can build server-side as well as client-side applications. It will lead your software application to deliver faster results in the full-stack web application development process.

2) Allowing Easy Scalability

The scalability of Node.js isn’t more efficient than Ruby, and PHP. Also, many platforms are more scalable than Node.js. Still, Node.js allows developers to scale products easily. Node.js framework event-driven programming and microservices architecture. Microservices are the small blocks of code or information to perform a function. It makes it easier of scaling up applications and also offers an easy way to add more microservices with existing ones without making any changes to it. Event-driven programming helps manage a website or application traffic without affecting the performance and accuracy of the software.

3) Easy to Learn

The Node.js application development framework is built using JavaScript at the core. A person who is having good skills in JavaScript development can learn Node.js easily. Every JavaScript programmer gets a junior position in Node.js development services. According to the report, more than 60% of developers prefer this programming framework as it is more satisfying than others. Node.js is having proper solutions to deliver the standards at all stages of the software development cycle. It allows app building without restrictions from scratch.

4) Saves Costs

Only the development and launching of the product is not enough. Software testing for bugs, the application or website management, updating software day-to-day, and many other tasks are to be completed. Additionally, collecting reviews and offering approval are conducted via the app. The Node.js itself has functionalities to remotely update apps with experiencing minimal disruptions. It will allow easy software maintenance, and save time, along with additional benefits. Removing the functionality of versioning will lead to a reduction in the cost of software maintenance.

5) Best for Mobile App Development

The demand for mobile devices has grown in the last some years. With the rise in mobile devices, mobile apps must be scalable at all and allow mobile friendliness. Mobile apps must be designed in a way to get an easy connection with desktop devices without losing features and performance. One can get the benefit from Node.js to launch successful mobile apps. It also allows application migration easiest to desktop programs.
