React Remains at the Top of JavaScript Frameworks

Did you know React was the second most commonly used framework after Node.js in 2022? Congratulations to all React fans out there!

Let’s stroll down memory lane and explore the birth of one of the most popular JavaScript tools. Back in 2011, Facebook developed React library to cater to the swiftly evolving traffic for its services. The initial iteration of React, known as FaxJS, was not yet a robust, efficient, or user-friendly library, but it helped develop user interfaces.

In 2013, Facebook made React an open-source project, and with the collaborative efforts of its maintainers, it now tops the charts of JavaScript developer libraries. React is widely used by many industry giants like Pinterest, WhatsApp, Instagram, Reddit, and Netflix. At Codica, we also use React for our projects. For example, we employed React to revamp a boat marketplace to make it fast, user-friendly, and profitable. Our client observed a 480% increase in lead generation performance compared to their previous platform.

React’s npm package remains top in 2022 and has enjoyed widespread popularity for years. It’s one of the most stable JS trends. However, Svelte has recently taken the first position. You can view the adoption trends of JavaScript frameworks in the graph below.

React 18 was released in 2022 and comes packed with new approaches and concepts. One of its key features is the implementation of a concurrency mechanism. React offers new features such as automatic batching, transitions, and client and server rendering APIs. Our team keeps a keen eye on the state of React and anticipates that 2023 will be an exciting year for React developers.

So, what makes Node.js so popular? Its efficiency and flexibility make development faster, resulting in more effective solutions. This JavaScript runtime environment enables the creation of lightweight and adaptable code. Web applications can easily scale by adding nodes vertically or resources horizontally, thanks to its modular structure, allowing changes to be made without affecting the entire system.

Node.js has proven to be useful in various scenarios, such as streaming media websites and resources with multiple file uploads, like Netflix, real-time applications that process short messages with minimal delays, such as LinkedIn and Trello, and microservices-based applications where only a particular service needs to be updated, such as interacting with PayPal.

The Node.js community continually contributes to the open-source platform, enhancing its capabilities and making it one of the latest trends in JavaScript technology. 

TypeScript is Experiencing Rapid Growth

TypeScript, developed by Microsoft in 2012, is a superset of JavaScript that addresses the lack of type restrictions in JavaScript. It adds optional types and enums to help organize code, making it easier to maintain growing codebases. Although there are many programming languages in the market, TypeScript has held steady in fourth place year-over-year and remains one of the most popular languages.

TypeScript uses the same syntax and semantics as JavaScript and adds additional features developers have longed for. Let’s look at the main advantages of TypeScript as one of the most powerful JavaScript trends.

One of the main advantages of TypeScript is that it’s easy for developers familiar with JavaScript to switch to TypeScript. Top JavaScript libraries and frameworks also support TypeScript, and it compiles readable and standard-based JavaScript. Additionally, TypeScript supports optional static typing, which helps detect bugs during compile-time rather than execution, resulting in higher-quality code.

Another advantage of TypeScript is its support for object-oriented features like interfaces, generics, and modules, making it ideal for creating large, complex systems that the modern web requires.

According to the Stack Overflow Developer Survey, TypeScript is among the 5 most loved programming languages in 2022. JavaScript trends indicate that the popularity of TypeScript will continue to grow in 2023. The wide adoption of TypeScript is one of the most influential recent JavaScript trends.

Vue.js

Vue.js is a popular web development framework that competes with React. While both frameworks have their strengths, Codica’s developers use Vue.js and React depending on the task required for custom software development. Vue.js is known for its modularity, elasticity, and progressiveness and has a big community and excellent documentation, making it an advantage for developers. The latest release, Vue.js 3.2.45, was released in 2022 and is on its way to version 3.3. This latest release improved app performance, smaller bundle sizes, and TypeScript support.

The enhancements to Vue.js are expected to impact JavaScript framework trends in 2023. These enhancements include increased performance, large-scale support, TypeScript integration, layered modules, and building UI component libraries. Vue.js 3.2 allows developers to optimize performance and type binding through the compiler or manually monitor rendering. The Composition API, built into Vue 3.0, makes organizing and reusing the code necessary for large projects easier. It improves readability, type-checking and complies with the latest JavaScript trends.

Vue 3 is built with TypeScript and provides bundled type declarations. The new virtual DOM and Composition API are compatible with TypeScript, which makes it one of the most liked trends of important JavaScript. Vue core has seen an architecture shift to decoupled modules, improving maintainability and introducing tree-shaking that reduces up to 50% of the runtime size. The new “define custom element” method allows building custom solutions using Vue component APIs. 

This feature enables developers to create UI component libraries driven by Vue and compatible with any framework. Vue continues to hold its significant place in JavaScript framework popularity and offers developers a straightforward and flexible way to create web apps. Developers can learn more about the latest enhancements in the Vue blog.

Svelte

Svelte is a front-end framework gaining popularity due to its component-based architecture. Its first version was released in 2016 and was written in JavaScript. However, the latest version, Svelte 3, released in 2019, is based on TypeScript. Svelte has become one of the top frameworks and is among the popular JavaScript trends in 2023.

Since the release of the TypeScript version, Svelte has gained much attention in the developer community. Svelte is a lightweight framework that enables developers to create powerful web apps. Unlike React and Vue, which convert applications into Vanilla JS code during runtime, Svelte performs this process during build time. 

There are several advantages to using Svelte, such as built-in reactivity for all components, enhanced runtime performance, and a compact and straightforward syntax that requires minimal boilerplate code. Due to these benefits, Svelte usage is expected to continue to expand as one of the significant JavaScript trends in 2023.

Angular Framework Enhancements for Improved Performance and Ergonomics

Despite its complexity, Angular is a popular framework for building robust and comprehensive solutions. Enterprises favor Angular because it can handle heavy loads, provide rich user experiences, and support visually appealing animations and themes. Big-name companies like IBM, freelancer.com, Weather and Forbes have chosen Angular to build their websites.

In 2022, the 14th version of Angular was released, which included bug fixes and new features contributed by community members. These enhancements make the development process more efficient and enable developers to deliver streamlined solutions. 

Some new features include stronger typing for routers and more tree-shakable error messages. You can read more about the updates in the Angular blog. Overall, Angular’s robustness and features continue to make it a popular choice among enterprises for building comprehensive solutions.

GraphQL

GraphQL is an increasingly popular data management tool released by Facebook in 2015. It is a query language that can power JavaScript applications and provides a flexible syntax for querying data from both the front and back ends. GraphQL is used by many popular companies such as GitHub, Pinterest, Coursera, and Shopify. As mobile devices are increasingly responsible for a significant share of all internet usage, efficient data loading is essential. GraphQL was created to increase the performance of data calls within Facebook’s apps.

GraphQL has many benefits that make it one of the most significant JavaScript trends in 2023, including fast data retrieval, boosted query efficiency, and customized requests. With GraphQL, data is collected under a single endpoint, requiring only one API call to retrieve the necessary data, which makes data retrieval fast. GraphQL uses graphs to define the data on the server, allowing data to be delivered in packages rather than through multiple API calls, which boosts query efficiency. GraphQL supports arguments for each field and nested object, including scalar fields, reducing complexity and focusing on essential information. These benefits can make GraphQL one of the most used JavaScript in 2023.

Web Components: The Building Blocks of Modern Apps

It is difficult to predict the popularity of JavaScript frameworks over the next five years. Still, web components are likely to be widely used in any popular framework or even in plain JavaScript. These building blocks of modern apps are called framework-independent or agnostic web components. They facilitate web development and reduce the time and costs needed to create an application.

But, what makes this concept so popular with other JavaScript trends, and how does it work? It is based on the following below specifications:

• Shadow DOM makes encapsulation of DOM subtrees into the web elements easier.
• Custom Elements allow developers to create new autonomous HTML tags.
• HTML Template reduces the page loading time by creating markup fragments 
• ES Modules makes it compatible.

The Power of Component-Based Architecture

A component-based architecture breaks down the design of an application into logical or functional elements that embody well-defined interfaces such as methods, properties, and events. This approach aims to improve component reuse, where each component is a self-contained unit encapsulating functionality.

In the context of the latest trends in front-end development and JavaScript, we can’t ignore an open-source platform called Bit. This tool is great for sharing, storing, and organizing web components from any project, promoting code reusability and collaboration on separate components. Implementing a component-based approach is one of the recent JavaScript trends that you should consider.

Jamstack 

Jamstack is a web development solution stack that enables developers to create fast and secure applications. Originally coined by Netlify, Jamstack has become a widely-used architectural method for building sites using various libraries and methods.

According to the Jamstack Community Survey, 47% of Jamstack developers work on edge-dynamic websites, and these platforms attract millions of users. Well-known examples of successful Jamstack sites include Louis Vuitton and Victoria Beckham Beauty.

There are several advantages of using Jamstack. For instance, changes require less code, making customization easier. Markup and assets are delivered via CDN, which enhances performance and aids in scaling the project for traffic spikes or projected growth. 

Additionally, Jamstack allows developers to use a microservices approach, which makes the app more maintainable. Jamstack pages are fast and light, ranking higher in Core Web Vitals. Moreover, server-side rendering mode generates content for highly dynamic websites when users request the page. Lastly, Jamstack websites are safe from hackers’ attacks because they do not have direct ties to sensitive information.

However, there are some drawbacks to using Jamstack. For example, third-party APIs may be used, which can cause the website to fail if the API fails. Coding is often required, and Jamstack is not always plugin-friendly. Every page needs to be created after making changes, which can be inconvenient for sites with many pages.

Despite these drawbacks, Jamstack engineers are working to address them, and with its many capabilities, Jamstack is expected to remain a trendy option in web development in 2023.
