Utilize Vue's prop system to pass objects between components

Question

Utilize Vue's prop system to pass objects between components

Can you help with passing objects as props in Vue? It seems like a simple task, but I'm having some trouble.

In my .vue file, I have the following code:

<template>
  <div id="scatter"></div>
</template>

<script>
export default {
  props: {
    data: {
      type: Object,
      default: () => ({}),
    },
  },
  mounted() {
    console.log(this.data);
  },
};
</script>

In the HTML, I attempt to pass the data prop like this:

<component :data="{x:1}"></component>

However, when I try to log it to the console, all I see is an empty observer object.

I think the issue lies elsewhere in your code because passing an object as a prop is quite straightforward:

// component registration
Vue.component('component', {
  props: {
    data: {
        type: Object
    }
  },
  template: '<div>Data: {{data}}</div>',
  mounted: function () {
    console.log(this.data)
  }
})

new Vue({
  el: '#example'
})

HTML:

<div id="example">
  <component :data="{x:1}"></component>
</div>

Update: Following my original response and setting up a JsFiddle, I am uncertain about the reason behind the behavior you mentioned. It seems to function properly when isolated in this scenario:

<script>
    export default {
       props: {
           ok: {
               type: Object,
               default: () => ({}),
           },
           data: {
               type: Object,
               default: () => ({})
           }
       }
     },
     mounted () { 
         console.log(this.data) // {x:1}
         console.log(this.ok) // {x:1}
     }
    }
</script>

Here is the corresponding HTML snippet:

<component :ok="{x:1}" :data="{x:1}"></component>
