Recently, we decided it was time to redo our own webpage to make it more modern and compelling. We used this opportunity to showcase some of the latest tools and technologies we like to use for projects like this. In the ever-evolving landscape of web development, it is crucial to stay up to date with the latest developments, but it's also important to know which of them are worth using. We believe that the most important metrics are efficiency, development costs, and time to market. Here are five of the most interesting modern web technologies that we used for this project.

1. CSS Houdini API

The CSS Houdini API is opening completely new ways to approach animations and styling in web development. Houdini opens the "black box" of CSS, allowing developers to directly interact with the browser’s rendering engine. This means that effects previously deemed too complex or performance-intensive to implement can now be created directly with CSS—eliminating the need for JavaScript workarounds.

For example, with Houdini, we can animate backgrounds, such as gradient shifts, entirely in CSS, which reduces code complexity and boosts page performance. Not only does this result in smoother animations, but it also improves load times and SEO compared to traditional workarounds like pre-rendered videos. Modern browsers already support many Houdini features, making it ready for production today. The possibilities for creative, lightweight visual effects are endless!

Below is a simple example of how Houdini can be used to create a custom background animation:

2. Dynamic Graphics with React and SVG

SVG (Scalable Vector Graphics) combined with React is a powerful way to create dynamic, responsive visuals on your website. SVGs are vector-based, which means they scale perfectly at any size without losing quality—unlike raster formats like PNG or JPEG.

When paired with React, SVG elements can be programmatically generated and made interactive, responding to users' device dimensions and user actions like clicks and scrolls. This approach allows developers to build reusable, animated components that remain lightweight and optimized for performance. Using server-side rendering (SSR) in React further enhances the performance, ensuring a seamless user experience across devices.

Here's an example of a simple SVG component created with React:

3. MDX: Flexibility for Content Management

MDX is a unique format that merges Markdown with JSX, striking a balance between traditional content management systems (CMS) and completely code-driven content creation. MDX allows non-technical users to write content using simple Markdown while giving developers the power to extend its capabilities with dynamic, interactive components.

By using MDX, we can create content that goes beyond static text, incorporating custom elements like charts, widgets, and code blocks. It also integrates seamlessly with CMS workflows, offering the best of both worlds—easy content management with the flexibility of custom components. It's an efficient way to keep content engaging while reducing the complexity of the editing process.

Actually, this blog post is written in MDX, showcasing the flexibility and power of this format. Here's an example of how the previous section of this article looks in MDX:

**SVG** (_Scalable Vector Graphics_) combined with React is a powerful way to
create dynamic, responsive visuals on your website. SVGs are vector-based, which
means they **scale perfectly at any size** without losing quality—unlike raster
formats like PNG or JPEG.

When paired with React, SVG elements can be **programmatically generated** and
made **interactive**, responding to users' device dimensions and user actions
like clicks and scrolls. This approach allows developers to build reusable,
animated components that remain **lightweight and optimized for performance**.
Using server-side rendering (SSR) in React further enhances the performance,
ensuring a seamless user experience across devices.

4. Server-Side Rendering with Next.js

Server-Side Rendering (SSR) is a technique that pre-renders web pages on the server before sending them to the client. Unlike traditional SPAs (Single Page Applications), where content is rendered in the browser, SSR delivers content directly from the server, resulting in faster initial load times and improved SEO.

Using Next.js for SSR brings additional benefits like automatic image optimization, prefetching, and efficient server-side caching. It combines the best of traditional static websites with the interactivity of SPAs, providing a fast, SEO-friendly experience with seamless navigation and user interaction. Whether it's an e-commerce site or a marketing page, SSR can significantly enhance your web experience.

LCP (Largest Contentful Paint) is a key metric for measuring page load performance. It represents the time it takes for the largest content element to be rendered on the screen. The LCP score for this page is ~100ms, which is considered excellent and is a result of using Next.js for server-side rendering. This ensures that the page loads quickly and provides a smooth user experience.

5. tRPC: Faster API Development with Fewer Bugs

API development has long been dominated by REST, but tRPC is a step forward, eliminating boilerplate and providing seamless type safety between server and client. With tRPC, there’s no need to create repetitive endpoints or serializers—changes made on the server are automatically reflected on the client, saving time and reducing errors.

tRPC's type safety ensures that types are shared across the entire codebase, minimizing the chances of bugs and keeping your application in sync. Even if you're currently using REST, tRPC can complement existing environments without compatibility issues, making it an excellent option for projects looking to increase efficiency.

Summary

These five technologies are reshaping the web development landscape by reducing complexity, enhancing performance, and improving the overall user experience. Whether you're interested in cutting-edge animations with Houdini, dynamic graphics with SVG and React, or streamlining your API development with tRPC, these tools can take your next project to the next level.
