vue-next

Status: Pre-Alpha.

We have achieved most of the architectural goals and new features planned for v3:

• Compiler

  • Modular architecture
  • "Block tree" optimization
  • More aggressive static tree hoisting
  • Source map support
  • Built-in identifier prefixing (aka "stripWith")
  • Built-in pretty-printing
  • Lean ~10kb brotli-compressed browser build after dropping source map and identifier prefixing

• Runtime

  • Significantly faster
  • Simultaneous Composition API + Options API support, with typings
  • Proxy-based change detection
  • Fragments
  • Portals
  • Suspense w/ async setup()

However, there are still some 2.x parity features not completed yet:

• Server-side rendering
• <keep-alive>
• <transition>
• Compiler DOM-specific transforms
  • v-on DOM modifiers
  • v-model
  • v-text
  • v-pre
  • v-once
  • v-html
  • v-show

The current implementation also requires native ES2015+ in the runtime environment and does not support IE11 (yet).
