The app we are going to use as playground is made of Vue app itself, Vue Router, and five components (TheFirstSimpleComponent, TheSecondSimpleComponent, etc).The router has a set of 5.

A prop to apply a prefix or suffix to option labels. And now you have a select with 50 props. And there will still be something that someone wants to do with the component that isn’t covered by those props. So you can instead supply a slot for the options html, and pass the option data along with it to give the maximum configurability.

Creating reusable interface components isn’t the only use for render props and scoped slots.

All developers using component-based architectures, such as Vue’s and React’s, know that creating reusable components is hard, and most of the time you end up having a lot of props in order to make it easier to control and customize a component from the outside.

That’s not bad, but it’s true that passing lots of props can get a bit cumbersome and ugly. However, there’s a way for every Vue.js component style to cope with it.

Let’s take as an example the vuetify’s button component, one of the simplest ones. Say that we want to pass the same bunch of props in most cases:

It could make sense to have them in a separate file, let’s call it props.js:

JSX and Render Functions

Since they give you more power and flexibility when it comes to rendering, it’s fairly easy to pass multiple props at once.

In a render function:

And in JSX:

Using a Vue.js template

What about using the Vue.js DSL (or template)? No worries, that’s also possible. All you need to do is to use the v-bind directive. Given an object that you must define in the data option of your component it will bind all props:

With this trick you won’t need to fill your template with repeated props at several places in your app, while still being able to use the beloved template tag.

Wrapping Up

Passing multiple props to a component can be simplified using the examples mentioned in this article. This is especially useful for presentational and third party components that have lots of props.

Keep in mind that the examples used here are merely educational. If you want to stay DRY (Don’t Repeat Yourself) there could be better approaches depending on the specific case, such as creating your own wrapper components.

In this article, we will get a full understanding of the vue slots through the practical application of its various use cases. Lets start with know about vuejs slots first.

What is Vue Slot?

Slots are reserved space offered by vuejs to display content passed down from one component to another. There are two types of the slot in vuejs namely: named slot and unnamed(default) slot.

Practical Use Case of Vue Slots

• To pass down Html elements from one component to another.

With props, Vue allows us to pass strings, objects, arrays, and functions from a parent component to its child component. While it is possible for us to pass HTML elements from a parent to its child component as a string this will make our website vulnerable to cross-site scripting attack that is why vuejs provides us with a slot which is a more secure and reliable method of passing HTML element and other contents from parent to its child component for rendering.

HOW TO USE SLOT In the child component where the content is to be displayed, add the slot tag as follows:

In this tutorial, we will generate our project with the Vue CLI

vue create slot-project

In the src folder create a components folder with parent.vue andchild.vue files

Adding the code below to child.vue

Add the code snippet below to parent.vue

Add the code snippet below to parent.vue

Here we imported the child component and pass down the HTML content to the child.

For these contents to be displayed in the child component, theslot tag must be added to the child component.

Lets add the slot tag to the child.vue file as follow:

In the app.js file add the parent.vue component

Now, we can verify that slot is working as expected.

Now our app should be like:

STYLING SLOT COMPONENT

For styling our slot component, the CSS styles should be added to the component with the slot tag.

So in child.vue component we will add the following styles to the HTML content received from the parent.vue component.

Using Multiple Slots

In order to use multiple slots in vue, vuejs provides us with away to name our slots.

What if we want the h2 and h3 tags in the parent component to be displayed individually in separate slots. This would be a typical use case for named slots.

In the Parent.vue component we will name our slots as follows:

In the child.vue component we will receive the named slot as follows:

Here vuejs reserves two slots to display the content of the slotattribute with the value of message and name as separate contents.
