This can make the template much cleaner, especially when the slot provides many props. It also opens other possibilities, such as renaming props, e.

Dynamic directive arguments also work on v-slot , allowing the definition of dynamic slot names:. Similar to v-on and v-bind , v-slot also has a shorthand, replacing everything before the argument v-slot: with the special symbol.

For example, v-slot:header can be rewritten as header :. However, just as with other directives, the shorthand is only available when an argument is provided. That means the following syntax is invalid:. Slot props allow us to turn slots into reusable templates that can render different content based on input props. This is most useful when you are designing a reusable component that encapsulates data logic while allowing the consuming parent component to customize part of its layout.

Instead of hard-coding the content for each todo, we can let the parent component take control by making every todo a slot, then binding todo as a slot prop:. However, even this barely scratches the surface of what scoped slots are capable of. For real-life, powerful examples of scoped slot usage, we recommend browsing libraries such as Vue Virtual Scroller , Vue Promised , and Portal Vue. The v-slot directive was introduced in Vue 2. The full rationale for introducing v-slot is described in this RFC.

The slot and slot-scope attributes will continue to be supported in all future 2. Deprecated in 2. See here for the new, recommended syntax. There can still be one unnamed slot, which is the default slot that serves as a catch-all for any unmatched content. In both examples above, the rendered HTML would be:.

Vue Router transitions are a quick and easy way to add some flair to Vue app. When used correctly, they can enhance the user experience by making your app feel more modern and professional. However, in newer versions of Vue Router, we have to use the v-slot to destructure our props and pass them to our inner slot.

This slow will contain a dynamic component surrounded by a transition component. Something like this:. And so on for each route that we want to have a transition. This way we can customize each route by changing the name of the transition. Our other option is to bind the name of our transition to a variable. Then, we can dynamically change this variable depending on our rotes. It uses a watcher on the current route to dynamically set the transitionName variable.

Adding a fade page transition is probably one of the most straightforward things we can add to our Vue app. For our new element to smoothly fade in, we need the current element gone before we start the new transition.

Note: these are the default names when you give your transition a name attribute the format of the class is name-enter-from , name-enter-active , and so on. We want our enter and leave states to have an opacity of 0.

Then, when our transition is active, we want the opacity to animate. This will cause our element to animate to the default opacity of 1 all by itself! The template will look like this. I also gave each a background color. Finally, our transition style will animate the absolute position of our components to slide them in.
