## What it is
Vue Vapor is a research fork of vuejs/core exploring a rendering mode for Vue that compiles components without the Virtual DOM. Development has moved to the vapor branch of the main Vue core repository, so this repo is no longer maintained.

## Use cases
- render vue components without virtual dom overhead
- research how vue vapor mode compiles templates
- explore vapor template output in a playground
- benchmark virtual-dom-free vue rendering
- prototype direct dom update strategies in vue

## When to choose
- you want to study the original vapor mode prototype or its template explorer
- you need historical reference for how no-vdom vue compilation was designed

## When to avoid
- you want to build a production app with vapor mode - use vuejs/core's vapor branch instead
- you need a maintained framework with active support
- you expect bug fixes or new features in this repository
