Top trends in Node.js to Watch in 2021

The year 2021 has just started, and everyone is predicting trends in their respective fields. After the COVID-19 pandemic, the E-commerce industry has blossomed like never before. More and more businesses are shifting their business models to virtual markets. In this rapidly growing software development, choosing the right framework has become one of the most important and complicated tasks.

Developers all over the world are also assuming many predictions for trends in Node.js for 2021. In this article, we will explain the expected trend in Node.js for 2021.

Let’s start the article by learning more about Node.js and its popularity.

What is Node.js?

Node.js is a JavaScript runtime built on Chrome’s V8 JS engine. It uses an event-driven, asynchronous, non-blocking input/output model (meaning how it interacts with the system’s disk and network, e.g., reading/writing data, making HTTP requests, etc.). It operates on a single thread event loop.

Node.js was created in 2009 by Ryan Dahl. He argued that software should be able to multi-task and said that the right way to handle several concurrent connections was to have a single-thread, an event loop, and non-blocking I/Os. This all made Node very efficient and eliminated the wait for requests.

More details about Node.js and why to choose it is linked in the article.

The popularity of Node.js has grown significantly in recent years because of its extremely lightweight and high flexibility. Node.js comes with an extensive library of JavaScript

modules that simplify the development process. Due to its open-source nature, Node.js has become incredibly popular for both web and mobile application development.

Recent statistics show that:

  • As of early 2020, more than 50% of the developers use Node.js in their projects.
  • In the USA, more than 28000 websites are built on Node.js technology.
  • Big names like eBay, AliExpress, and others are relying on Node.js.
  • Node.JS is used by websites that get heavy traffic, such as Netflix, PayPal, and Groupon.
  • Since 2009 when Node.js was introduced into the developer world, its popularity has wildly grown. In Github, Node.js has 75.9k stars, 19k forks, and 3k watchers. In Stack share, it has 71.8k followers and 8.3k votes. These numbers alone can show how popular Node.js is. Popular tech giants like Microsoft and Netflix use Node.js.
  • Node.js won the top spot in the StackOverflow’s 2020 developer survey. Over half of the respondents in the survey reported having used it in their projects.

Meteor.js

Meteor.js is an open-source platform that is used by millions of developers to develop web and mobile apps. It is well-known among developers for making javascript applications simple, efficient, and scalable. It took over a decade of hard work by the industry giants to make it to its perfection. Meteor is a mature open-source framework that allows you to build and scale efficiently so you can serve millions of users.

Koa.js

Koa.js middleware stack flows in a stack-like manner, allowing a developer to perform actions downstream then filter and manipulate the response upstream. Koa is a new web framework designed by the team behind Express, aiming to be a smaller, more expressive, and more robust foundation for web applications and APIs. By leveraging async functions, Koa allows developers to ditch callbacks and greatly increase error-handling. Koa does not bundle any middleware within its core, and it provides an elegant suite of methods that make writing servers fast and enjoyable.

Sails.js

Sails.js - one of the most famous MVC frameworks for Node.js. It is designed to match the familiar MVC pattern of frameworks like Ruby on Rails, but with support for modern apps' requirements. It provides features like data-driven APIs with a scalable and service-oriented architecture.

Hapi.js

Hapi.js is an open-source framework for web and desktop applications. It is most commonly used to build web services such as JSON API, websites, and HTTP proxy applications. The mobile team created the framework at Walmart Labs. Mr. Eran Hammer, who created OAuth, was the brain behind this technology. He designed it to handle their traffic for Black Friday events, one of the busiest days for online shopping in the U.S. calendar. The original versions of Hapi used the Express framework.

NestJS

NestJS is an open-source, extensible, versatile, progressive Node.js framework for creating compelling and demanding backend systems. It is currently the fastest-growing Node.js framework in TypeScript. NestJS is used for writing scalable, testable and loosely coupled applications. It brings scalable Node.js servers to a whole new level.

Check out more reasons why you should choose Nest.js as your desired Framework in this detailed article.

Moving on to the main topic of the article and checking out the top trends in Node.js to watch in 2021.

Here’re some of the most predicted trends in Node.js that will help businesses leverage their potential and get an edge over their competitors in 2021.

Trend # 1: GraphQL Deployment in Node.js apps

GraphQL is a query language. By using GraphQL, a client can request for the data they need from the server, and the server will send a JSON response to the query. The interesting thing to note here is that the client can ask for exactly what they need, and they receive only what is required.

The Popularity of GraphQL in 2020

  • An emerging Node.js trend - GraphQL has grown immensely in popularity over the last two years. Due to its ability to streamline the workflow on multiple platforms, it has become the choice of millions of developers worldwide.
  • The GraphQL Foundation, a newly established organization hosted by the Linux Foundation, governs developments around GraphQL. GraphQL servers are available for multiple popular languages, e.g., Java, JavaScript, Ruby, Python, Perl, C#, Go, etc.
  • The popularity of GraphQL grew rapidly. E.g., The State of JavaScript 2018 report mentions that only 5% of developers surveyed had used it in 2016. However, 20.4% of developers used it in 2018.

GraphQL is the best Alternative for REST API And Why should it be used?

GraphQL offers several advantages over REST, which are as follows:

  • Apps using REST APIs call endpoints. The entire data in that endpoint will be returned in the JSON format. This results in over-fetching as well as under-fetching, which can cause scalability and performance issues. GraphQL, with its queries, schemas, and resolvers, enables developers to design API calls that meet their specific data requirements. This way, GraphQL resolves the over-fetching and under-fetching challenges.
  • Due to designing the endpoints according to the view in the application using REST API, it can create a bottleneck when the application needs quick iterations on the frontend. Such iterations might require more data in the frontend, or they might require fewer data. GraphQL doesn’t create such a bottleneck due to its flexibility. The iterations for developing the frontend can continue without having to change the backend.
  • Applications built on REST API get all the data in the Endpoint. The application owner can’t gain insights into specific data elements since the entire data is returned every time. Whereas, in GraphQL, a developer can use the specific queries to retrieve specific data elements. This enables the application owner to gain insights into which data elements are in demand. Moreover, they will know which data elements aren’t being used by clients anymore.

Trend # 2: MEAN & MERN Stack

MEAN (MongoDB, Express, Angular, Node.JS) and MERN (MongoDB, Express, React, Node.JS) are the two stacks that constitute amazingly powerful technologies in the field of app development. These technologies are rapidly growing open-source web and app development frameworks that enable a developer to develop complex applications and frontend web apps.

These technologies are used by some of the biggest tech companies, like Netflix, which boost its popularity. Netflix's entire website relies on the MERN stack framework for the smooth web development experience.

Trend # 3: Real-Time Apps

In the year 2021, people demanded real-time apps for different online activities. These real-time apps are the most common cause of Node.js. With amazing user-engagement, real-time apps not only provide a set of incredible features but speed as well. These apps include features like live chats, social media integration, ad servers, gamification, stock exchange features, etc. Node.js fits all the requirements in this ecosystem.

Node.js apps can serve thousands of servers for data-intensive and real-time IoT device apps as well. However, there is one drawback of these real-time apps as they can overload a server. Node.js makes the collaboration environment update seamlessly due to Event API and Web Sockets. Trello is one of the biggest examples of a web-app where a real-time collaboration pattern is implemented.

The other kind of real-time apps which can be build using Node.js frameworks are:

  • Video conference apps
  • Document sharing apps
  • Voice over Internet Protocol
  • Online gaming
  • E-commerce transactions like stockbroking
  • Instant messaging apps

Because of the fast performance and open-source flexibility, Node.js has been a popular choice among the top-notch web and app developers worldwide.

Trend # 4: Serverless Architecture

Node.js is most famous for its serverless architecture. It means that to create an application, a developer does not have to worry about maintaining the servers.

A serverless architecture reduces the dependency on hardware and servers, which leads to less cost of development. It also offers numerous advantages, and the biggest advantages are overall-low project cost, high code quality, low module cost, and better flexibility.

Trend # 5: Internet of Things (IoT)
