Babel Preset JSX
Configurable Babel preset to add Vue JSX support. See the configuration options here.
Installation
Install the preset with:
npm install @vue/babel-preset-jsx @vue/babel-helper-vue-jsx-merge-propsThen add the preset to .babelrc:
{
"presets": ["@vue/babel-preset-jsx"]
}Syntax
Content
render() {
return <p>hello</p>
}with dynamic content:
render() {
return <p>hello { this.message }</p>
}when self-closing:
render() {
return <input />
}with a component:
import MyComponent from './my-component'
export default {
render() {
return <MyComponent>hello</MyComponent>
},
}Attributes/Props
render() {
return <input type="email" />
}with a dynamic binding:
render() {
return <input
type="email"
placeholder={this.placeholderText}
/>
}with the spread operator (object needs to be compatible with Vue Data Object):
render() {
const inputAttrs = {
type: 'email',
placeholder: 'Enter your email'
}
return <input {...{ attrs: inputAttrs }} />
}Slots
named slots:
render() {
return (
<MyComponent>
<header slot="header">header</header>
<footer slot="footer">footer</footer>
</MyComponent>
)
}scoped slots:
render() {
const scopedSlots = {
header: () => <header>header</header>,
footer: () => <footer>footer</footer>
}
return <MyComponent scopedSlots={scopedSlots} />
}Directives
<input vModel={this.newTodoText} />with a modifier:
<input vModel_trim={this.newTodoText} />with an argument:
<input vOn:click={this.newTodoText} />with an argument and modifiers:
<input vOn:click_stop_prevent={this.newTodoText} />v-html:
<p domPropsInnerHTML={html} />Functional Components
Transpiles arrow functions that return JSX into functional components, when they are either default exports:
export default ({ props }) => <p>hello {props.message}</p>or PascalCase variable declarations:
const HelloWorld = ({ props }) => <p>hello {props.message}</p>Compatibility
