Passing props dynamically to dynamic component in VueJS

I've a dynamic view:

<div id="myview">
  <div :is="currentComponent"></div>
</div>

with an associated Vue instance:

new Vue ({
  data: function () {
    return {
      currentComponent: 'myComponent',
    }
  },
}).$mount('#myview');

This allows me to change my component dynamically.

In my case, I have three different components: myComponent, myComponent1, and myComponent2. And I switch between them like this:

Vue.component('myComponent', {
  template: "<button @click=\"$parent.currentComponent = 'myComponent1'\"></button>"
}

Now, I'd like to pass props to myComponent1.

How can I pass these props when I change the component type to myComponent1?

To pass props dynamically, you can add the v-bind directive to your dynamic component and pass an object containing your prop names and values:

So your dynamic component would look like this:

<component :is="currentComponent" v-bind="currentProperties"></component>

And in your Vue instance, currentProperties can change based on the current component:

data: function () {
  return {
    currentComponent: 'myComponent',
  }
},
computed: {
  currentProperties: function() {
    if (this.currentComponent === 'myComponent') {
      return { foo: 'bar' }
    }
  }
}   

So now, when the currentComponent is myComponent, it will have a foo property equal to 'bar'. And when it isn't, no properties will be passed.

You can also do without computed property and inline the object.

<div v-bind="{ id: someProp, 'other-attr': otherProp }"></div>

Shown in the docs on V-Bind - https://vuejs.org/v2/api/#v-bind

You could build it like...

comp: { component: 'ComponentName', props: { square: true, outlined: true, dense: true }, model: 'form.bar' }
     

<component :is="comp.component" v-bind="{...comp.props}" v-model="comp.model"/>
