Vue js – Ep. 7 Using Slots

In this episode, we will learn about using slots in Vue.js. Slots are a powerful feature in Vue that allow for the dynamic insertion of content into a component.

What are slots?

Slots are placeholders in a component that can be filled with content when the component is used. This allows for the flexibility of passing content into a component from the parent component, without having to hard-code the content in the component itself.

Using slots in Vue.js

To use slots in Vue.js, you can define a slot in the component using the <slot> tag. For example:

<template>
  <div>
    <h2>This is a component with a slot</h2>
    <slot></slot>
  </div>
</template>
    

In the above example, the <slot> tag is used to define a slot in the component. Now, when the component is used, any content passed to the slot will be rendered in place of the <slot> tag.

Named slots

In addition to the default slot, Vue.js also supports named slots. This allows for more fine-grained control over where content is inserted in the component. To define a named slot, you can use the name attribute on the <slot> tag. For example:

<template>
  <div>
    <h2>This is a component with named slots</h2>
    <slot name="header"></slot>
    <slot name="content"></slot>
  </div>
</template>
    

Now, when using the component, you can pass content to the named slots using the v-slot directive. For example:

<my-component>
  <template v-slot:header>
    <h2>This is the header</h2>
  </template>
  <template v-slot:content>
    <p>This is the content</p>
  </template>
</my-component>
    

In this example, the content passed to the v-slot directives will be rendered in place of the named slots in the component.

Conclusion

Using slots in Vue.js provides a powerful way to create flexible and reusable components. By allowing for the dynamic insertion of content, slots enable you to create components that can be easily customized and adapted to different use cases.
