In Vue.js, a scoped slot is a directive that allows you to render a child component within the parent component.

The scoped slot will only render the child component if the parent component has the same name as the scoped slot. For example, if you have a parent component called “my-component” and a child component called “my-child-component”, you can use the scoped slot directive to render the child component within the parent component.

The scoped slot directive is used like any other directive in Vue.js.

You simply add it to the template of the parent component. In the example below, we add the scoped slot directive to the template of the “my-component” component:.

The scoped slot directive has one attribute: name. The name attribute is used to specify the name of the child component that you want to render.

In our example above, we want to render the “my-child-component” component within the “my-component” component.

The scoped slot directive will only render the child component if both components have the same name. This is why it’s important to use a unique name for each scoped slot.

If you don’t use a unique name, Vue.js will throw an error.

Once you’ve added the scoped slot directive to the template of the parent component, you need to add the child component within the parent component’s script tag:

// Import the child component
import MyChildComponent from ‘./MyChildComponent.vue’;

export default {
components: {
// Register the child component
‘my-child-component’: MyChildComponent
}
}.
