UnJS: Nuxt 3 behind the scenes
summary
A breakdown of the actual pieces powering Nuxt 3: a reusable ecosystem called UnJS with 55+ packages (auth, fetch, storage, config, image optimizer ipx, unimport, unplugin, giget), design rules favoring modularity and composition, and concrete tooling like unbuild used by 2,000+ repos to compile packages and 132M+ npm downloads/month across the org. H3 and Nitro provide a tiny, composable server runtime that benchmarks among the fastest; these components are production‑tested inside Nuxt 3 and actively maintained.
