Pass object as prop on Vue

Question

How do you go on passing objects as props on vue? I would imagine this would be a simple task but apparently not.

I have the following code on a .vue file:

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

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

On html I try to pass the data props as follows :

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

When I try log it into the console the result is only an empty observer object.

I believe the problem is somewhere else in your code as passing an object as a prop is as simple as you imagine:

// register the component 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>

Edit: After my initial answer and creating a JsFiddle, I am not sure why the behavior you described is happening. It works when narrowed down to the use case:

<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>

And the HTML:

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

v-bind="yourObject"

Should do on <my-component v-bind="yourObject"><my-component>

Not sure about <component></component>. Still digging into Vue. Try and let us know.
