[Vue @Component] Pass Props Between Components with Vue Slot Scope & renderless component

Components with slots can expose their data by passing it into the slot and exposing the data using slot-scope in the template. This approach allows you to pass props down from Parent components to Child components without coupling them together.

For example, we have two components, Settings and Layout component:

<Settings>
    <Layout></Layout>
</Seetings>

We want Layout get data from Settings component, we can do it with slot-scope

Seetings.vue:

<template>
    <div>
        <slot :header=header :footer=footer></slot>    
    </div>
</template>
<script>
import {Component, Vue} from 'vue-property-decorator'

export default class Settings extends Vue {
    header = 'This is data for header'
    footer = 'This is the data form footer'
}
</script>

Actually this is the same as Renderless component:

 // Renderless component
<script>
export default {
    render() {
      return this.$scopedSlot.default({header: 'xxx', footer: 'xxx'})
   }
}
</script>

Layout.vue:

<template>
    <div class="flex flex-col h-screen">
    <slot name="header">
      <h1 class="text-red">Please add a header!</h1>
    </slot>
    <slot name="content">
      <div class="text-red flex-grow">Please add some content</div>
    </slot>
    <slot name="footer">
      <h2 class="text-orange">Please add a footer!</h2>
    </slot>
    </div>
</template>

HelloWorld.vue:

<template>
  <Settings >
    <Layout slot-scope="props">
        <header slot='header' class='p-2 bg-blue text-white'>{{props.header}}</header>
        <div slot="content" class="flex-grow p-3">Amazing content</div>
         <h2 slot="footer" class="bg-grey-light text-blue p-2 text-center">{{props.footer}}</h2>
    </Layout>
  </Settings>
</template>

<script>

import {Component, Prop, Vue} from 'vue-property-decorator'
import Layout from './Layout';
import Settings from './Settings';

@Component({
  components: {
    Layout,
    Settings
  }
})
export default class HelloWorld extends Vue {
  @Prop({
    default: 'Default message from Hello World Component'
  })
  message

  onClick() {
    this.message = 'Goodbye'
  }
}
</script>

The concept is a bit similar to Angular ngTemplateOutlet
