Syntax

Content

functional component

const App = () => <div></div>

with render

const App = {
  render() {
    return <div>Vue 3.0</div>
  }
}
const App = defineComponent(() => {
  const count = ref(0);

  const inc = () => {
    count.value++;
  };

  return () => (
    <div onClick={inc}>
      {count.value}
    </div>
  )
})

Fragment

const App = () => (
  <>
    <span>I'm</span>
    <span>Fragment</span>
  </>
)

Attributes/Props

const App = () => <input type="email" />

with a dynamic binding:

const placeholderText = 'email'
const App = () => (
  <input
    type="email"
    placeholder={placeholderText}
  />
)

Directives

It is recommended to use camelCase version of it (vModel) in JSX, but you can use kebab-case too (v-model).

v-show

const App = {
  data() {
    return { visible: true };
  },
  render() {
    return <input vShow={this.visible} />;
  },
};

v-model

Note: You should pass the second param as string for using arg.

<input vModel={val} />
<input vModel={[val, ['trim']]} />
<A vModel={[val, 'foo', ['bar']]} />

Will compile to:

h(A, {
  'foo': val,
  "fooModifiers": {
    "bar": true
  },
  "onUpdate:foo": $event => val = $event
})

custom directive

const App = {
  directives: { custom: customDirective },
  setup() {
    return () => (
      <a
        vCustom={[val, 'arg', ['a', 'b']]}
      />
    );
  },
}

Slot

const App = {
  setup() {
    const slots = {
      a: () => <div>A</div>,
      b: () => <span>B</span>
    }
    return () => <A vSlots={slots} />
  }
}
