## @vue/babel-sugar-functional-vue
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](https://github.com/vuejs/babel-plugin-transform-vue-jsx)
### Usage
Install the dependencies:
```sh
# for yarn:
yarn add @vue/babel-sugar-functional-vue
# for npm:
npm install @vue/babel-sugar-functional-vue --save
```
In your `.babelrc`:
```json
{
"plugins": ["@vue/babel-sugar-functional-vue"]
}
```
However it is recommended to use the [configurable preset](../babel-preset-jsx/README.md) 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:
```js
// 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>
}
```
