Vite - Marchant Web Case Study

Vite is a next-generation build tool that offers a fast and modern development experience, making it a favorite among front-end developers. It's used by many popular frameworks, including React, Angular, Vue, Solid, Svelte, and many others. With over 15 million weekly npm downloads and more than 6 million dependent projects, Vite has become a cornerstone of modern web development, supported by a vibrant community of over 1,000 contributors.
In early 2024, Evan You, the creator of Vue.js and Vite, approached me with an exciting opportunity: he wanted to completely overhaul the Vite homepage to better represent the project's growth and vision. This redesign was also part of a larger initiative tied to the launch of VoidZero, a VC-backed company Evan was starting to take Vite and other projects into the future. This was an incredible chance to contribute to a tool that has become a core part of modern web development.
The design by Vincent Rodriguez (@the_rmoon) featured detailed animations and interactivity that represented the future-facing vision of Vite. Thanks to Vincent's well-organized Figma designs, I was able to work asynchronously. He even fully mocked up the animation sequences, using Figma magic that’s frankly above my pay grade. His work speaks for itself in everything he does.
The project presented a unique challenge. Vite is known for being "blazingly fast", with a history of obsessive focus on performance, so the website needed to communicate that in its own performance metrics. I wanted to ensure that the page loads immediately and never felt "laggy" in terms of frame rate or interactivity. Additionally, we had to minimize any dependencies, as they would propagate downstream to all projects using Vite. GSAP was the only new dependency, used for handling complex animations, and added only as a development dependency to avoid it impacting downstream production bundles.
I began by cloning the Vite repo and diving into the VitePress installation for the homepage and docs. This was admittedly one of my earliest projects using VitePress specifically, but it supports Vue components out of the box, making it very easy to work with. My approach was to first establish an initial layout for each section and build the components one by one. Once the structure was in place, I centralized logic into composables to make the code more efficient and organized. I find this iterative approach—getting something up quickly and refining it continuously—produces my best work. I like to tinker and nitpick until I'm happy with what I see.
With the DOM structure ready, my animation strategy was twofold: use CSS for simpler animations and SVG components for more complex ones. I aimed for a responsive approach, wherein desktop interactions trigger hover animations, while mobile used scroll-based viewport triggers.
The main Vite CPU "chip" in the hero animation is a prime example of the CSS-first approach. The reflective highlight effect was achieved with two linear gradients moving at different speeds, paired with rounding, blurring, and a color-dodge blend mode. This technique created an organic, curved look despite using simple rectangular shapes.
The specular edges utilized a Chromium browser quirk to transition between gradients, creating a sense of moving environment lighting. I'm honestly not sure if that's a bug or a feature.
For more intricate animations, like glowing nodes moving along curved paths, I developed a reusable SvgNode component. This component accepted props for path, position, and color, rendering an SVG element accordingly. The glowing effect was achieved by shifting a radial gradient along the path and masking it:
GSAP was then used to animate these props, creating smooth animations that could handle various easing effects and "stick" the SVG dots to the underlying line paths.
Performance was a key focus throughout. The gradient background in the hero section is a great example of my continuous improvement approach.
Initially, I used two colored circles with a large blur filter. Later, I optimized it to a single background gradient for color, combined with a masked radial gradient for lighting, plus a light grain texture to reduce color banding. This significantly improved mobile performance without compromising the visual style.
Mobile optimizations included reducing transparency and heavy effects like backdrop blur, which are resource-intensive. For animations, I used GPU-friendly CSS properties, leveraging will-change and other CSS tricks to push animations to the GPU, while avoiding repaints by animating only opacity and transform. Every component was thoroughly tested across browsers and screen sizes to ensure optimal performance. If we could squeeze a few milliseconds out of a frame's render time, consider it squeezed.
It was a joy and an honor to work on this project for the Vite community, and I'm happy to say it was well-received at ViteConf 2024. You can visit the new site at vite.dev or check out the repo at vitejs/vite. Feel free to explore the site and see the work firsthand. If you’re inspired, consider contributing to the Vite project and becoming part of this thriving community - you won't regret it! 😉

Grab your sense of humor and prepare to dive headfirst into this crazy coding adventure.
Introducing "usePartyRef" for @vuejs. It's a ref() that syncs in real-time with other clients using @partykit_io.
This was a fun one to build, with the design by none other than @the_rmoon 👏
