Project mention: Preact vs Astro 4: The Performance Battle benchmark in High-Scale | dev.to | 2026-05-07
Preact’s 3.2kB core is already small, but high-scale apps often bloat bundles with unnecessary dependencies, utility libraries, and duplicate code. First, audit your bundle with webpack-bundle-analyzer or source-map-explorer to identify large dependencies. Replace moment.js (67kB gzipped) with date-fns (12kB gzipped) or dayjs (2kB gzipped) for date formatting. Use preact/compat only if you need React ecosystem libraries, as it adds ~1kB of overhead. Enable strict tree shaking in your bundler: for Vite (recommended for Preact), set build.rollupOptions.treeshake: 'smallest' to eliminate all unused code. In our 10k component benchmark, enabling strict tree shaking reduced Preact bundle size by 38%, from 1.2MB to 744kB. For server-side rendering with Preact, use preact-render-to-string instead of React’s renderToString, which is 40% faster for large component trees. Always minify and gzip your bundles: use vite-plugin-compression to generate pre-compressed .gz and .br files, which reduce transferred bytes by 60-70% for text-based assets. Avoid bundling large static assets (images, videos) with your JS bundle; use a CDN like Cloudflare or AWS CloudFront instead, which reduces server load and bundle size.

Parcel - Blazing fast, zero configuration web application bundler

I guess this is the most tricky part, given that you usually do not have any visibility at that point (unless you are a well-known figure in the industry). In order to match our format we needed two speakers, so that was our first goal. Luckily, Erfan Ebrahimnia was working at MASSIVE ART at the time, and volunteered to have a talk about Grunt. Additionally, we have tweeted (yes, I did that at the time) to find another speaker, to which Christoph Klocker responded to suggest doing a talk about Sass. And yes, both of these topics were cutting edge back then!
