The digital world has grown in leaps and bounds in the past few years. Spurred by the pandemic, the physical world – in an unprecedented manner – made a shift to the digital world.

This, in turn, raised expectations in terms of operational efficiency among businesses. Today, businesses are adopting and adapting to technological advancements to keep up with the changing industrial landscape.

The challenge, however, lies in picking out the best tech stack. This is where the most popular and trusted modern application framework – Node.js – makes its entry.

Node.js development services are extremely popular as this framework is being used by a wide range of businesses such as Netflix, Twitter, etc. for their server-side application development.

StackOverflow’s 2022 Developer Survey shows that Node.js was chosen by 47 percent of its respondents and hence earned its position as the most popular web technology among web developers.

If you are wondering what Node js development services are and how they can add value to your business, read on to learn everything about Node.js!

What is Node.js?

In technical terms, Node.js is described as a single-threaded, open-source, cross-platform runtime environment that facilitates the development of server-side and networking applications that are fast and scalable.

In simpler terms, Node.js offers a balanced intersection of frontend and backend technologies. This means that it extends the capability of JavaScript to run on the server side of both web application architecture as well as serverless architecture.

If an analogy is to be drawn, Node.js is comparable to Java which also runs applications in its runtime. The ease of use and efficacy of Node.js is the reason for the boom in Node js development companies in the USA.

Node.js Frameworks / Approaches

Node.js is on its own an extremely powerful and versatile platform. However, several frameworks and approaches have also been developed to increase the efficiency of Node.js.

Here is a quick snapshot of these frameworks that contribute extensively to Node.js development services:

NestJS

NestJS is built on an abstraction of other Node.js frameworks such as Fastify and Express. This framework is extensible, versatile, and open-source and includes TypeScript, which is a subscript of the popular JavaScript. The abstraction makes this framework easier and faster for developers to learn and work on projects.

Modules, providers, and controllers form the foundation of the NestJS foundation. The first concept – Modules- is nothing but logical units of code put together. All applications need at least one root Module.

However, depending on the code organization, web developers may build more Modules on top of the code. The second component – providers – are abstractions of the code that can be injected at a certain stage as dependencies.

The third and last component – controllers – front end by taking in client requests, executing application logic, and responding.

Due to its ease of use and extensibility, NestJS is quite popular and offers a host of benefits. They are great for developing microservice architecture, lend a strict project structure, and enable a team of programmers to undertake a less bug-ridden development process.

ELECTRON

Electron combines the Node.js runtime with the Chromium rendering engine and facilitates the easy development of desktop applications on JavaScript. Furthermore, it also allows programmers to develop desktop applications in HTML5 and CSS, which are platform-agnostic web languages. Overall, it makes packaging and installation of these applications easier.

Electron is best suited for businesses that require desktop applications. Its framework allows speed up the development process and, therefore, it can be extremely helpful for a business that is looking for quick marketing of its new products.

DENO

The third framework – DENO – addresses the most critical aspect of the application – security, compatibility, and modules. DENO was introduced in 2018 by the creator of Node.js specifically to address the challenges that developers were facing.

The advantage that DENO offers is that the runtime executes in a sandbox safely isolated from the file systems. As a result, attackers are prevented from breaking out and securing access to the server the code is running on.

By allowing modules to be directly imported by a URL, DENO does away with the necessity for a centralized package management system. Also, DENO supports TypeScript which enhances browser compatibility – thus earning its popularity among web developers.

Why Use Node.js?

The popularity that Node.js and the surge in demand for Node.js development services are because of the ease it offers and its applicability in different types of use cases.

Here are a few reasons why you should use Node.js:

Applications are Lightweight and Fast

Node.js is particularly useful when it comes to building small, fast and scalable applications. Collaboration tools and instant messaging apps are the best examples. When coupled with fast synchronization abilities, Node.js can be useful for event-based applications too.

Flexible and Useful in Building Serverless and Microservice Architecture

Node.js is an extremely flexible framework that allows it to be used for the development of serverless and microservice architecture.

Both design styles are extremely popular because they help in saving resources and efficiently manage application lifecycles.

This is nudging more and more businesses across the globe to engage in Node.js development services.

Internet of Things

Node.js is efficient at handling multiple connections and hence works well with IoT. Node.js can successfully handle small messages that are relayed over multiple devices and hence it is very efficient when applied to IoT.

Processing Audio or Video

Another area where Node.js finds much application is processing audio and video. This is because Node.js can much more effectively handle asynchronous input and output. For instance, you can easily and quickly configure a streaming setup using Node.js.

Minimal Ramp Up Times

Because Node.js is built on common web languages, it is very easy to use and hence cuts down on ramp-up time and engineering resources, significantly. Cost efficiency is one of the major reasons for companies to engage in Node js development services.

Integration with C++ Code

As the Node.js runtime is built on a C++ server, it can seamlessly integrate with C++ libraries. As a result, Node.js quickly transmits data between the application code and C++.

How is Node.js Different from Other Backend Technologies?

Each framework is distinct and designed for a specific purpose. While the differences may not be blatantly apparent, they do exist.

Here is a quick comparison of Node.js with Java and Python.

Node.js Vs Java

Node.js and Java are often compared because both run their programs within their own runtime environment. However, there is a clear distinction between the two.

Java has a syntax similar to C++ and is an object-oriented programming language. This makes Java-heavy to use and costly to develop.

Node.js on the other hand is lightweight and based on non-compiled programming languages such as JavaScript.

Node.js is preferred for I/O applications for this reason. Furthermore, its efficiency in handling server-side HTTP requests is another reason that adds to its popularity.

Node.js Vs Python

Python is also widely popular among developers because of its simple syntax and ease of use. However, Python is more comparable to Java in terms of its object-oriented language.

While it is interpreted like JavaScript, its programs are seen to consume a sizeable volume of computing resources.

When Not to Use Node.js?

Node.js is not recommended for application development for fintech. The reason for this is the specifics of work with the floating decimal point that can lead to an accumulation of errors.

Similarly, it is not the best choice when it comes to working with heavily loaded threads that involve a CPU.

Trends in Node.js in 2023 and Beyond

Gauging by the popularity that Node.js enjoys currently, it would be safe to say that it will see much more adoption and integration as the world of business transitions into a more web-driven world.

However, some other Node.js frameworks will also see greater adoption in the coming years.

Frameworks such as Deno are expected to see more adoption due to their modularity and extensibility.

Similarly, Bun, which is a new runtime for JavaScript and TypeScript holds much potential as it offers higher performance and speed.

Amplify, which is a full-stack framework by AWS, and Remix – a newer web technology – is expected to trend in the coming years.

It heightens the speed and overall performance of the program.

Building Real-time Application

Building Real-time application
Numerous enterprises and tech startups are developing a substantial part of their backend infrastructure using Node js for real-time applications. Before the advent of Node js, the applications were less efficient and expensive due to high resource utilization. Thus, Node js had paved the way for real-time apps ever since.

Server-Side Rendering (SSR)

Server-side rendering SSR
Web apps written in JavaScript are capable of functioning without server-side rendering by a Node server. It is because web browsers can render JavaScript along with HTML and CSS on the client-side. Server-side rendering in JavaScript-based web applications makes it useful for search engine optimization. All central Node js frameworks like Express and Koa assist SSR. When using Node, you expose your JSON documents with a REST API for the front-end to read. A JSON database declares query results that can be parsed easily, straightaway by JavaScript.

How to Use Node.js Architecture to Build Highly Scalable Apps?

Node.js for Scalable Apps

Node.js is ideal for building highly scalable, data intensive, real-time back-end services that power our client applications. You might ask but there are other tools and frameworks out there for building back-end services such ASP.NET, Rails, Django, etc., why choose Node? Before answering the question, let’s understand Node.js architecture.

Node’s “Single Thread” Architecture

Node applications are highly scalable because of the non-blocking or asynchronous nature of Node. What do you mean by asynchronous? As a Node.js developer, let me give you an analogy.

You go to a restaurant. A waiter comes to your table, takes your order, and gives it to the kitchen. Then the waiter moves to serve another table while the chef is preparing your meal. The same waiter can serve many different tables and don’t have to wait for the chef to cook one meal before serving another table.

This is what we call non-blocking or asynchronous architecture and this is how Node applications work. The waiter is like a thread allocated to handle a request. So a single thread is used to handle multiple requests.

In contrast to non-blocking or asynchronous architecture, we have blocking or synchronous architecture. To understand the latter architecture, let’s go back to our restaurant analogy. You go to another restaurant, and in this restaurant, a waiter is allocated to you. The waiter takes your order and gives it to the kitchen. Now he is sitting in the kitchen waiting for the chef to prepare your meal, not doing anything.

One way to look at this analogy is this that the waiter is just waiting. He will not take an order from another table until your meal is ready. This is what we call blocking or synchronous architecture. Now, coming back to your question, that’s how applications built with frameworks like ASP.NET, Rails, and Django work out of the box.

Nodes single thread Architecture

In this architecture, when a server receives a request from the client, the thread is allocated to handle that request. As a part of handling that requests, the thread might query a database, which may take a little while until the result is ready. When the database is executing the query, that thread is sitting there waiting. It can’t be used to serve another client’s request and the server has to allocate it another thread.

If we have a large number of concurrent clients with their requests, at some point we’re going to runout of threads to serve these clients. New clients have to wait until free threads are available. If we don’t want them to wait, we need to add more hardware. That’s why Node.js development companies are in great demand these days.

A real-life example

The real-time chat app to support your helpdesk is based on blocking or synchronous architecture and, consequently, for each new conversation, the app creates a new thread. Let’s say each thread occupies 2MB of RAM and the server has 8GB of RAM installed. The RAM will max out at 4000 concurrent conversations. If you have managed a chat support center, then you know 4000 conversations at a time aren’t surprising. Upgrading server, we all know is a costly affair.

Node.js real-life example

In contrast, a Node.js based real-time chat app can, virtually, achieve scalability levels of over 1M concurrent conversation on a single thread in the same amount of RAM. Of course, even the largest of support centers don’t process this many requests at a time. This is the magnitude of scalability a Node.js application can deliver.

Node’s “Single Thread” Advantage

In blocking or synchronous architecture, we are not utilizing our resources efficiently. That’s why applications built with frameworks like ASP.NET aren’t exactly scalable as they max out at the hardware’s maximum ram.

On the other hand, Node.js Platform uses “Single Threaded Event Loop” architecture to handle multiple concurrent clients. Node.js Processing model is JavaScript Event based model with callback. This is how the model works.

Node.js Single Thread Advantage

Node web server accepts requests and puts them in event queue. The web server continuously polls for new requests from client in an infinite loop called Event Loop. Event loop is at the heart of Node.js applications and gives them the unparalleled scalability I am talking about.

The event loop operates under single thread in Node. The event loop runs endlessly across the event queue, seeking new client requests. If it finds a new request in the queue, it will flag it as either blocking or non-blocking. The event loop will process the non-blocking request and send the response to user.

Things get a little interesting when the request requires server to perform a blocking I/O operation like accessing the file system or raising a SQL query. In that case, event loop assigns that request a thread and goes about polling for fresh requests in the event queue. The thread, in the meanwhile, processes the thread, performs blocking operations, and sends it back to the event loop with a response. The event loop sends the response back to the client.

An ideal architecture to build scalable apps

Asynchronous architecture makes Node ideal for building applications that include a lot of disk or network access. Your application can serve more clients without the need to throw in more hardware. Thus, Node.js applications are highly scalable.

What are the Best Node js Frameworks?

Best Node.js Frameworks

Node js turned the tide across web development when it brought JavaScript under aisle of backend development and made way to fullstack development entirely in JavaScript. JavaScript has been a dominant frontend technology–alongside HTML and CSS–since the days of Netscape. However, its existence as a backend technology was next to none until 2009 when Ryan Dahltook Google Chrome’s V8 engine, which is normally confined to the browser, added an event loop, package manager and a low level I/O API, embedded inside a C++ program and called it Node.

The possibility of writing backend code in JavaScript opened a whole new world to web developers, who could now access the files, listen to network traffic and HTTP requests, access databases directly, etc. all with a line of JavaScript code. This led to many Node js frameworks. You all must have heard of Express but there is more to Node js.

There are tens of Node js frameworks available each overcoming a specific limitation of standalone Node package. Of course, all the frameworks I am going to mention here are available for download on your favorite package manager.

Backend Frameworks

1. Express.js

Express is the most popular Node js framework and a component of MEAN stack. A majority of full stack developers employ the Express framework to setup an HTTP server in Node js with easier to use, feature-rich Express APIs. Express APIs, essentially, add a set of additional features to already robust Node js API architecture without overriding it.

However, Node js has its own share of limitations. The most profound of them is Express requires a little more manual actions than most JavaScript developers are accustomed to. Alienated developers may also dislike the larger footprint of web applications developed in Express.

This may make you ask the question,“why is it still so popular?” The obvious answer is Express has its own little ecosystem of itself. That is a Node js developer can easily extend Express, which is itself an extension to Node, with an Express Framework framework like Kraken.js. Kraken.js isn’t the only one.

express.js frameworks

This level of extensibility has garnered Express.js support of major startups into mobile space: MySpace, PayPal, and Klout, which, gradually, led to wider developers’ and makers’ adoption and attention respectively.

2. Hapi.js

What happens when one of the Fortune-500 companies turns up against the likes of Amazon and eBay on Black Friday to compete in online sale finds Express.js a little short of their expectations? It commissions Hapi.js, a Node framework that builds on the shortcomings of Express and shares the same codebase.

Express is a lightweight framework perfect for building your next single-page application on. If you expect your server application to scale at the enterprise level, then this isn’t the framework I would recommend. I am not commenting about the final application’s performance as it would behave as would any other JavaScript application.

Hapi addresses the biggest shortcoming Express.js has that makes Express unsuitable for developing enterprise applications—the inability to split code into small chunks. Enterprise applications can go thousands of lines of code and are, generally, coded by distributed engineering teams. The inability to split codes into small chunks bounds achievable code distribution amongst teams or, in terms of enterprise developers, limits extensibility and maintainability.

Hapi.js is extendable with a rich set of plugins for adding enterprise functions to a Node application, including authorization, authentication, metrics, and logging. Hapi developers tend to focus more on writing reusable application logic than spending time building infrastructure. OpenTable, Macy’s, Condé Nast, and Disney are users of Hapi.js.

3. Koa.js

Koa.js is once again a Node js framework to build applications and APIs on. Koa is the brainchild of initial contributors to the Express.js project on GitHub. It works more or less like Express, except it uses generators to manage callbacks and is more tolerant to errors.

Developers developing applications that will generate too many callbacks can save many complications by choosing Koa over Express.js.

MVC Frameworks

MVC frameworks

4. Total.js

All the above Node js frameworks are great for building server applications but not creating complete web apps with frontend and backend. For building a web application, developers ask for MVC frameworks like Ruby on Rails or Laravel. Total.js is a sort of MVC framework that is built upon Node js like others in the list but provides approachable endpoints to integrate database and frontend technology of your choice.

The Node part of Total.js, in addition to a full web server, includes SMTP mail client, image processing algorithms and web socket among a few. At the time of writing, Total.js was compatible with Angular, Backbone, React, Ember, and of course, Bootstrap when it comes to front-end frameworks and MongoDB, CouchDB, PostgreSQL, SQLite and MySQL when it comes to databases.

5. Sails.js

Sails.js is Ruby on Rails equivalent on JavaScript, particularly when handling HTTP requests. I mean it is a MVC micro-framework for building full-stack enterprise applications very much like Total.js. Sails.js is compatible with most frontend JS frameworks Total.js is.

The two chief ingredients of Sails.js are Express.js and Socket.IO. The ability to generate RESTful JSON models with support for WebSockets and HTTP makes Sails.js a perfect framework to write data-oriented and real-time applications like chat portals.

6. Meteor.js

Full-stack JavaScript applications developed in Meteor contain client-side and client-side rendered JavaScript, the pertaining logic, and markup files. Meteor.js has fewer commonalities than Node js frameworks mentioned above. Unlike Express, it’s highly opinionated and strictly follows MVC framework architecture, which may annoy developers coming from lightweight frameworks like Express and Koa.

Meteor.js even has default elements for every component in its web development stack. Of course, they are interchangeable but this makes the framework less flexible.

Real-time Application Development

7. DerbyJS

Derby is a special purpose Node framework for developing web applications to enable real-time collaboration. To enable collaboration between its users, DerbyJS has a dedicated data synchronization engine, Racer. Racer syncs data between users and makes real-time collaboration a possibility.

Also, DerbyJS is an MVC framework. That is, the view is updated every time the model changes. Also, DerbyJS applications are search engine friendly.

8. Socket.IO

Socket.IO enables real-time communication in chat apps. It opens an event-driven, duplex communication between client and server. A WebSocket-compatible server,Socket.IO provides real-time collaborative features and analytics.

Socket.IO is platform agnostic and goes with almost every device, OS, or browser. One of its tops clients is Flightcar. FlightGear, as the name suggests, rents cars from the airport while traveling.

API Platforms/ Frameworks

9. StrongLoop/LoopBack

LoopBack, along with the StrongLoop API platform, is a vastly extensible Node js API framework developed by IBM. LoopBack APIs connect devices and integrate Android and AngularJS SDKs for mobile app development.

When it comes to supporting for databases, LoopBack supports all major database systems: Oracle, Mongo, and SQL. StrongLoop is a special version of Node js and a stress-free API tool for Express professionals.

10. ActionHero.js

This fast, lightweight Node js server builds reusable, scalable API servers that are inter-compatible and are backward compatible. By using the same API code for HTTP and socket transports, it gives access to APIs and any static data on the server to an authorized client.

TaskRabbit and Samsung are two key Actionhero.js users.

Final Thoughts

The Node js ecosystem is vast and will only grow in the future. Most of the Node js frameworks described above are quite mature and backed by a large community. Node, or JavaScript, as a back-end technology makes for fantastic real-time applications for collaboration, chatting, etc.

Since most of the mentioned Node js frameworks are either based on Express or built by the same team, they share a lot of common features and, thus, give an easy switch to developers moving from one to another. A developer moving from Express to StrongLoop for developing an API server will only take a couple of hours to make the switch.

While I am not a big fan of opinionated Node js frameworks and would prefer lightweight Express with little additions, these MVC frameworks lets you build fantastic applications without paying too attention to setup and thus saving you a lot of precious time.
