Why?

@TheAlexLichter

  • Dependencies came out with major (internal) changes
    • Vue 3
    • Webpack 5
  • Vite had been released as "next generation" tooling
    • Nuxt module for Nuxt 2 available
    • but deeper intergration desirable
  • Internal refactorings that would cause breaking changes
  • Improve support for deployment (serverless + workers)
  • Make vue-router optional (for very simple sites)

unjs

  • Decoupled modules
  • Powering the Nuxt core
  • Can be used in any JS/TS project
  • Easier to test than the full core
  • Helpful for other projects too

⚡️ Batteries included

@TheAlexLichter

  • Includes common libraries if necessary (e.g. vue router)
  • Easy manipulation of the document head (useMeta)
  • Configured build tools out of the box (PostCSS, ESBuild, Webpack5/Vite)
  • Basic but flexible folder structure
  • File-system-based routing
  • Supercharged components
    • layout concept
    • create easy transition between pages
    • composables to make data fetching a breeze

@TheAlexLichter

There can be many folders

But you only need an app.vue to get started

FS Routing explained

@TheAlexLichter

🚀 Optimized

@TheAlexLichter

  • Code-splitting by default
  • Sensible default configs
  • Asset fingerprinting (& cache busting)
  • Modern mode
  • Smart prefetching
