|
||
|
|
|
||
|
|
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>
|
||
|
|
}
|
||
|
|
```
