## @vue/babel-sugar-v-on
Syntactic sugar for v-on in JSX.
### 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-v-on
# for npm:
npm install @vue/babel-sugar-v-on --save
```
In your `.babelrc`:
```json
{
"plugins": ["@vue/babel-sugar-v-on"]
}
```
However it is recommended to use the [configurable preset](../babel-preset-jsx/README.md) instead.
### Details
This plugin adds v-on to the JSX and tries to mirror the same behaviour as in vue-template-compiler, with a few differences:
1. You should use underscore (`_`) instead of dot (`.`) for modifiers (`vOn:click_prevent={this.test}`)
2. It is recommended to use camelCase version of it (`vOn`) in JSX, but you can use kebab-case too (`v-on`).
```js
export default {
methods: {
test() {
console.log('Hello World')
},
},
render(h) {
return (
<div>
<a href="https://vuejs.org" vOn:click={this.test}>Vue</a>
</div>
)
},
}
```
