When, How And Why Use Node.js As Your Backend?

Backend is an important part of every software as it serves the functionality of a software product. Hence the selection of technology stack for this is also an important task. There are three fundamental things behind the decision of a technology stack for your software. 

  • Business priorities and objectives
  • Specifications of your business domain and market
  • Specifications of the technology stack itself.

Server side is the most significant part of your product. Among all conceivable back end development technologies to look over, Node.js is one of the essentials. It incorporates a wide variety of modern business domains and actual cases. The advantages of Node.js are uncountable, yet you ought to likewise know about its constraints. Get a full picture of Node.js and abstain from doing serious mistakes being developed that could cost you money.

What is Node.js?

Node.js is an application runtime environment that allows you to develop server-side applications in JavaScript. Its one of a kind I/O model exceeds expectations at the kind of scalable and real time situations we are progressively requesting of our servers. It is lightweight, efficient. Ability of Node to use JavaScript on frontend and backend opens new ways for development. This is the reason that many big companies are using Node. Here we will discuss about- When it is good to use Node and when not? 

How Node.js is different from web JavaScript?

There is no difference between web JavaScript and Node.js in terms of the language used. JavaScript used in browsers and in Node.js is actually the equivalent. Then what makes it special? Node has different set of APIs. In browsers, you have an variety of DOM/Web APIs uncovered that help you connect with UI and enable you to get to access the hardware. Node.js has many APIs that are suitable for backend development, for instance, support for file systems, http requests, streams, child processes etc. Browsers do offer some essential support for file systems or http requests, yet those are typically constrained because of security concerns. You can also know the JavaScript concepts that Node.js programmer must know at- 10 JavaScript concepts every Node.js programmer must master.

Why is it worth developing your project in Node.js?

As a matter of first importance, utilizing it as your server technology gives your team an extraordinary lift that originates from utilizing a similar language on both the front end and the back end. This, implies your team is increasingly productive and cross-functional, which, thusly, prompts lower development costs. Also it is good to mention that JavaScript is a popular programming language, so your applications code will be easy to understand for developers.

You can likewise reuse and share the code between the frontend and the backend parts of your application, which accelerates the development process. In addition, the community of Node.js is continuously increasing (StackOverflow questions are increasing), so the knowledge base for technology is widely available. The fact that the entire Node.js technology stack is open-source and free is additionally extraordinary news. Node offers a great package manager, npm and the amount of available open-source tools in npm’s registry is massive and rapidly growing. Here we will include some advantages of Node.js that you should consider when choosing a technology for a project.

Real time applications-

Choosing Node.js is good for those applications that need to process a high volume of short messages requiring low inertness. Such applications are called real time applications (RTAs). Node.js is used to create it effectively. Node.js will be the right choice for real-time collaborative apps, where you can watch the document being modified live by someone( for eg., Trello, Google Docs). You can develop video conference app, online gaming apps, e-commerce transaction software with Node.js. It can handle multiple client requests, enables sharing and reusing packages of library code and data sync between client and server can be very fast.

Fast and scalable environment-

Ruby on Rails probably won’t be sufficient regarding speed, if you have a huge amount of requests. Node.js will demonstrate valuable in circumstances when something quicker and more versatile than Rails is required. Node’s capacity to process numerous requests with low response times, just as sharing things, for example, validation code between the client and server, make it an extraordinary fit for modern web applications that carry out lots of handling on the client’s side. Hence Node.js is popular among single-page applications because there all rendering is done on the client’s side and the backend only provides a JSON API. Node.js also proves to be useful when you need to process high volumes of IO-bound requests. It won’t generally be all that proficient if a lot of CPU processing is required to serve the request. 

When you should not choose Node.js?

Applications with monolith architecture-

Monolithic apps contain lots of functionality. And Node.js is a single threaded platform. When something is being executed in a single thread, the rest of to pause. Server limits are utilized in a problematic manner, since one thread uses one processor core. Therefore large Node.js applications are created as sets of microservices or under a service-oriented architecture made of several services. Monolith applications of any complexity are acceptable if there is no high load involved.

Complex CPU calculations-

Node.js isn’t the best choice with regards to work with highly loaded threads that include CPU. For instance, when audio and video processing is written on the back end.

Package Quality-

There are more interesting points before commencing with Node.js. There are many packages available in npm for Node.js. The community of it is active and npm is the largest available repository these days. But packages vary in their quality. Some of the time, you can detect issues with packages supported just by individual clients and not kept up appropriately; for example, when associating your Node application to an old database framework.

How to use Node.js for your project?

When you choose a Node.js for your project development, go to the official web page of Node.js and download the Node.js package. After that, you need to install the Node.js package manager to install and manage the dependencies in project easily. Visit nmpjs.com and follow the installation instructions. Now you are ready to code.

The best beginning stage for the Node is the official guide, from which you can gain proficiency with the core concepts of Node.js. In it’s guide, you can find answers to most of the questions. Then you can try out some important frameworks such as express.js to get an overview of how JavaScript dependencies are used. It allows you to build high-performance, scalable and easily maintainable applications in JavaScript. The best learning method for express.js is to visit the official guides on the express.js web page. Now you will be ready to build applications.
