- ## @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>
- }
- ```
