React.js Technologies to Watch in 2024

With the introduction of React Hooks, React.js emerged as the leading fully functional UI framework. I previously delved into this 'Functional UI revolution' in my 2020 post, which I've republished here for reference. If you're embarking on a new frontend project in 2024, it's crucial to stay informed about the latest and greatest in the React.js ecosystem. In this post, I'll provide a brief review of the most promising and impactful React.js technologies to watch out for in 2024.

React Server Components

2024 has ushered in an exciting development in the React.js ecosystem with the advent of React Server Components. This groundbreaking feature enables developers to strategically split rendering tasks: static parts of the content can be rendered on the server, while dynamic elements requiring JavaScript functionality are handled on the client side. This approach not only enhances load performance and data efficiency but also optimizes the overall user experience. React Server Components mark a significant shift towards more versatile, hybrid architectures in React applications, empowering developers to craft web experiences that are both dynamic and highly performant.

Next.js: The Undisputed Leader in the React Ecosystem

The realm of Server Side Rendering (SSR), with frameworks like Gatsby and Next.js, has long been pivotal for rendering static websites. However, the Vercel team behind Next.js has truly set a new standard by swiftly embracing? React Server Components and elevating the architecture of Next.js to the next level. Versions 13 and 14 of Next.js introduced revolutionary features, including enhanced automatic static optimization, superior image optimization capabilities, and better integration with Vercel's edge. A particularly standout feature in Next.js 14 is the advanced code splitting and prefetching, significantly boosting application performance and enhancing the user experience. These progressive enhancements firmly establish Next.js as the frontrunner in the React ecosystem, leading the way with innovation and efficiency.

Tailwind CSS: Disrupting Traditional CSS Practices

Tailwind CSS has emerged as a disruptive force in web design, challenging traditional approaches to styling such as semantic UI. Adam Wathan, the creator of Tailwind CSS, advocates for a utility-first approach, where CSS is written in a way that prioritizes reusability over semantic naming. This approach deviates from the conventional practice of creating CSS classes based on content or structure, such as .author-bio or .article-preview, which often results in a strong coupling between CSS and HTML. Instead, Tailwind promotes the use of utility classes that can be applied across various elements, regardless of their semantic meaning. For example, classes like .rounded or .hover:bg-blue-700 focus on styling aspects without being tied to specific content types.

Adam Wathan's insights into the relationship between HTML and CSS reveal that traditional "separation of concerns" might not be as clear-cut as previously thought. In many cases, semantic CSS ends up mirroring the HTML structure it styles, leading to a form of coupling that Tailwind CSS seeks to avoid. By focusing on utility classes that apply specific styles, Tailwind encourages a more flexible and efficient way of writing CSS that's not overly reliant on the HTML structure. This shift in approach has been a game-changer in the web development world, embraced widely for its practical benefits in creating responsive, aesthetically pleasing, and highly functional web designs.? Tailwind's approach promotes a more efficient, maintainable, and scalable styling practice, making it a popular choice among developers and frameworks, including Next.js and various UI component libraries.

Shadcn UI: A Novel Approach to UI Component Collections

There are many component libraries based on Tailwind CSS. Among them is Shadcn UI which represents a unique approach in the realm of UI component libraries. Unlike typical libraries such as Material UI or Chakra UI, Shadcn UI is not actually a component library in the traditional sense. It is defined as "a collection of reusable components that we can copy and paste into our apps". This innovative approach allows developers to directly download the source code for individual UI components into their codebases, providing a high degree of modularity and customization.

Built on top of Tailwind CSS and Radix UI, Shadcn UI supports a variety of frameworks including Next.js, Gatsby, Remix, Astro, and Vite, making it versatile for different development environments. Despite being a relatively new entrant in the web development ecosystem, it has quickly gained popularity, demonstrated by its viral growth and substantial GitHub stars.

Witness to Shadcn UI popularity is an AI tool v0.dev developed by Vercel. This tool allow to create fully functional part of UI based on Shadcn UI and React.js.

Vercel AI SDK: The Catalyst for 2024's AI Chatbot Revolution

The year 2022 marked a pivotal moment in the adoption of AI technologies, witnessing their transition into mainstream applications. This era saw the emergence of groundbreaking advancements of zero shot AI models like? CLIP, a surge in AI art, and most notably, the ChatGPT revolution, which transformed how we interact with digital platforms.
