Vuejs Dynamic Slots
This page assumes you've already read the Components Basics.Read that first if you are new to components. # Slot Content Vue implements a content distribution API inspired by the Web Components spec draft (opens new window), using the slot element to serve as distribution outlets for content. 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: And in your Vue instance, currentProperties can change based on the current.
Next Up, Let’s review Named Slots in VueJS with the help of an example. We covered a lesson on slots in VueJS in the last section. slots help us to take the defined content inside the HTML markup of the component and put them in wherever specified in the template. The problem is it only works for a single default slot.
But what if we want to create more complex markup, where we are looking to accept different content from the user which we have to place at different locations.
Vuejs Dynamic Slot Content
Let’s understand this with the help of an example.
We are looking to convert the Bootstrap Card markup to a Vue Component. Here is generic HTML markup of a Bootstrap card.
And this gives out a generic card styling in the output.
We want the user to be able to specify content to be slotted in the card header, card body, and card footer.
Named Slots in VueJS
Let’s approach it using named slots in VueJS.
Here is the Vue Component code, we have defined the Bootstrap Card markup in our HTML and we have replaced the text with slot element.
Vuejs Dynamic Slots Definition
Notice that the slots are named. The name of the first slot is header, The second one is without a slot that means this is the default slot, the name of the third slot is the footer.
Now let’s see how we can pas content to different slots from our HTML markup.
We have defined the first template with v-slot:header directive inside the component markup. This denotes that text that should go into the header slot. There is a similar template with v-slot:footer directive which denotes the content that should go into footer slot.
Also, there is HTML content defined without any directive which gives an indication to VueJS to put it inside the default slot.
Fallback Content
VueJS slots also have provision for fallback content is no content is supplied to the slot.
Notice our VueJS component for footer slot we have defined a fallback content.
If no content is supplied to the footer slot from the markup, then the slot will be replaced with the default content provided.
That’s all about Named Slots in VueJS.
