Vue.js known as javascript hooks

I've been working on connecting Vue.js with velocity.js. Following a guide, I found an example that doesn't use a named transition. Currently, my transition code looks like this:

<transition name="collapse">

https://v2.vuejs.org/v2/guide/transitions.html#JavaScript-Hooks

In the Vue.js documentation, they show how to set up transition elements with JavaScript hooks:

<transition
  v-on:before-enter="beforeEnter"
  v-on:enter="enter"
  v-on:after-enter="afterEnter"
  v-on:enter-cancelled="enterCancelled"
  v-on:before-leave="beforeLeave"
  v-on:leave="leave"
  v-on:after-leave="afterLeave"
  v-on:leave-cancelled="leaveCancelled"
>

Is there a way to automate this process without setting it all up manually? It would be ideal to have a named animation without the need for extensive setup.

I was hoping to define methods in my Vue.js component like this:

collapseEnter, collapseEnterCancelled, etc.

However, it appears this approach does not function as expected. Do I really have to configure all the directives or is there a simpler solution available?

To streamline hook functions, consider creating an abstract component that automatically binds them. This method may seem hacky, but it should effectively achieve the desired result.

Start by defining a component named autoTransition:

Vue.component('autoTransition', {
  props: ['name', 'vm'],
  functional: true,
  abstract: true,
  render (h, ctx) {
    return h('transition', {
      name: ctx.props.name,
      on: {
        'before-enter': ctx.props.vm.beforeEnter,
        'enter': ctx.props.vm.enter,
        // ... other hooks
      }
    }, ctx.children)
  }
})

Simply integrate this component into your code like a regular transition. Instead of individually passing each hook function, you can now directly pass the entire vm (accessible through $root) along with the specified name:

<auto-transition name="myTransition" :vm="$root">
  <h1 v-show="someBool">hello</h1>
</auto-transition>

In my opinion, the name is only utilized when adding CSS classes for transitioning. It does not relate to any javascript hooks. Therefore, all hooks must be defined explicitly.
