If you are a Vue developer, then you must have heard about scoped slots in Vue.js. Scoped slots are an essential feature of Vue.js that allows developers to create reusable components and inject dynamic content to child components.
Scoped slots provide a way to pass data from the parent component to the child component without using props. In this article, we will discuss what are scoped slots in Vue.js and how they work.

What Are Scoped Slots?
Scoped slots are a feature of Vue.js that allows developers to pass data from the parent component to the child component through templates. In other words, it provides a way for child components to receive data from their parent components without using props. Scoped slots provide a mechanism for creating reusable components that can be used across different applications.
How Do Scoped Slots Work?
Scoped slots work by allowing developers to create templates inside the parent component and then pass these templates as props to their child components. The child component can then use these templates to render dynamic content.
For example, let’s say we have a parent component called `App.vue` and a child component called `Child.vue`. We want to pass some data from the parent component to the child component without using props. We can do this using scoped slots.
First, we need to define a template inside the `App.vue` file:
-
Create template for App.vue:
-
<template>
-
<child>
-
<template v-slot:default=”slotProps”>
-
{{ slotProps.text }}
-
</template>
-
</child>
-
</template>
-
In this template, we create a `child` element and define a slot named `default`. The `v-slot` directive is used to define the slot and its name.
We also pass the `slotProps` object to the child component. This object contains all the data that we want to pass from the parent component to the child component.
Now, let’s define the child component:
-
Create template for Child.vue:
-
<template>
-
<div>
-
{{ $slots.default({ text: ‘Hello, World!’ })}}
-
</div>
-
</template>
-
In this template, we use the `$slots` object to access the slot that was defined in the parent component. We pass an object containing our data as an argument to this slot.
In this case, we are passing a string ‘Hello, World!’ as data.
When we render these two components using Vue.js, we will see ‘Hello, World!’ displayed in our browser. This is because we passed this string from our parent component to our child component using scoped slots.
Conclusion
Scoped slots are a powerful feature of Vue.js that allows developers to create reusable components and inject dynamic content into their child components. Scoped slots provide a way for child components to receive data from their parent components without using props. Scoped slots can help you create more flexible and reusable components in your Vue.js applications.
