Properties added via Mixin are not updated

[SergejKasper]

Hallo Karol,
i've come across the following issue when using vue-mixins with custom elmenents:

Steps to Reproduce:

1. Create a component, register it as a custom element and add a prop via vue-mixin
   -> The default of the prop is displayed properly
2. Change the prop by assigning a different value (as attribute or via js)
   -> The prop is not being updated

When taking a look in the debugger i discovered that the
__vue_custom_element__.$options.props
are only showing the component's own props

Confirmed, vue-custom-element looks for props only directly in Vue component passed to Vue.customElement, not in it's mixins.

Corresponding code -

vue-custom-element/src/utils/props.js

Line 35 in ac5be50

if (componentDefinition.props && componentDefinition.props.length) {

As I'm about a holiday leave it might take a while to fix this. Regards!

Thank you for the quick reply.
I checked vue-extends in the meantime. As your comment suggests we have the same issue there.
Have a nice holiday! I'll work around this for the time being :)
