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

• You should use underscore (_) instead of dot (.) for modifiers (vModel_trim={this.test})

export default {
  data: () => ({
    test: 'Hello World',
  }),
  render() {
    return (
      <>
        <input type="text" vModel_trim={this.test} />
        {this.test}
      </>
    )
  },
}

custom directive

const App = {
  directives: { custom: customDirective },
  setup() {
    return () => (
      <a
        vCustom={{
          value: 123,
          modifiers: { modifier: true },
          arg: 'arg',
        }}
      />
    );
  },
}
