Syntactic sugar for functional components.

Babel Compatibility Notes

• This repo is only compatible with Babel 7.x, for 6.x please use vuejs/babel-plugin-transform-vue-jsx

Usage

Install the dependencies:

# for yarn:
yarn add @vue/babel-sugar-functional-vue
# for npm:
npm install @vue/babel-sugar-functional-vue --save

In your .babelrc:

{
  "plugins": ["@vue/babel-sugar-functional-vue"]
}

However it is recommended to use the configurable preset instead.

Details

This plugin transpiles arrow functions that return JSX into functional components but only if it's an uppercase variable declaration or default export:

// Original:
export const A = ({ props, listeners }) => <div onClick={listeners.click}>{props.msg}</div>
export const b = ({ props, listeners }) => <div onClick={listeners.click}>{props.msg}</div>
export default ({ props, listeners }) => <div onClick={listeners.click}>{props.msg}</div>

// Result:
export const A = {
  functional: true,
  render: (h, {
    props,
    listeners
  }) => <div onClick={listeners.click}>{props.msg}</div>
}
export const b = ({ props, listeners }) => <div onClick={listeners.click}>{props.msg}</div>
export default {
  functional: true,
  render: (h, {
    props,
    listeners
  }) => <div onClick={listeners.click}>{props.msg}</div>
}
