Vuact

Vuact is a React runtime compatibility layer for Vue 3. It enables seamless usage of the React component ecosystem inside Vue 3 projects, with two-way interoperability between Vue and React for components, events, reactivity, Context, Ref, and more.

Key value:

• Seamlessly use React components in Vue apps
• Support bidirectional migration: Vue ↔ React
• Use Vue and React in the same application
• Build cross-stack component libraries in a React-like way

Quick Start

For the full configuration and initialization flow, see setup-config.md.

Core Capabilities

1. Component Conversion

Vuact provides two core functions to convert components between Vue and React:

• r2v (react-to-vue): Convert a React component into a Vue component
• v2r (vue-to-react): Convert a Vue component into a React component

Examples:

• r2v Basics
• v2r Basics

2. Slots and Render Props

Vuact provides a flexible slots and render-props transformation mechanism:

• On the Vue side, you can pass children, element props, or render props to React components via slots

• On the React side, you can pass slots to Vue components via props prefixed with slot:

• r2v Render Props and Slots

• v2r Slots

3. Events and Props Interop

Vuact automatically transforms props and events between Vue and React:

• Vue class → React className
• Vue style (string or object) → React style (object)
• React className → Vue class
• React style (object; auto-add px for unitless values) → Vue style
• Vue v-model update events → React onUpdate:xxx

Examples:

• r2v Event Callbacks
• v2r Event Callbacks

4. Context Interop

Vuact supports two-way Context passing between Vue and React:

• On the Vue side, you can provide React Context to React components via provideContext
• On the React side, you can provide Vue Context to Vue components via VueContextProvider
• Context can pass through both frameworks

Examples:

• r2v React Context
• r2v Vue Context
• v2r React Context
• v2r Vue Context

5. Ref Interop

Vuact supports passing refs between Vue and React components:

• On the Vue side, use ref to get a React component instance
• On the React side, use ref to get a Vue component instance
• For function components, expose methods via useImperativeHandle

Examples:

• r2v Component Ref
• v2r Component Ref

6. Use Vue Hooks in React Components

Vuact lets you use Vue reactivity directly inside React components:

• Create a Vue reactive scope via useVueEffectScope
• Use Vue hooks like ref, watch, computed, etc. within that scope
• Combine the reactivity systems from both frameworks

Examples:

• r2v Vue Hooks
• r2v Hybrid Components

Compatibility and Limitations

Version Compatibility

• React: mainly compatible with React 16–18; React 19 support is in progress
• Vue: requires Vue >= 3.5
• Build tools: ESM-only; requires a modern bundler

Known Limitations

Because Vuact is essentially based on Vue, some behaviors cannot fully match React:

1. Concurrent rendering: Vue renders recursively, so React concurrent rendering cannot be replicated
2. Commit phase: Vue mutates the DOM during recursive rendering; there is no explicit commit phase like React
   • useInsertionEffect timing differs from React
   • getSnapshotBeforeUpdate timing differs from React
3. Event system: @vue/runtime-dom cannot fully match react-dom
   • react-dom's SyntheticEvent differs from standard web events
   • react-dom applies special handling for some native DOM elements (e.g. input, form, etc.)
