How to use slot in vue

Slots in Vue.js simplify application development by rendering specific content at different locations in a component. There are three types of slots: named slots, default slots, and scoped slots. The benefits of slots include code reuse, flexibility, and scalability. In the example, the parent component defines Slot, and the child component uses Slot to present different content.

Usage of Slot in Vue

Slot in Vue.js is a powerful tool that allows Components render specific content at different locations in the parent component. By using Slots, you can create flexible and reusable components that simplify application development.

Usage of Slot:

1. Define Slot in the parent component:

   • Use the <template></template> tag to define a Slot and give it a name, such as <slot name="header"></slot>.

2. Use Slot in the child component:

   • In the template of the child component, use tag to insert the Slot content defined by the parent component.
   • If no name is provided, default Slot is used by default.

Types of Slots:

There are three types of Slots in Vue.js:

• Named Slot: With a Slot specified by a name, content can only be inserted using that name in the parent component.
• Default Slot: Slot with no specified name, accepts any inserted content.
• Scope Slot: The Slot that passes data, allowing child components to access the properties and methods of parent components.

Benefits of Slot:

Using Slot has the following benefits:

• Code reuse: Create reusable components without having to rewrite code.
• Flexibility: Allows the parent component to insert different content as needed.
• Extensibility: Easily extend the functionality of components by creating custom slots.

Example:

The following is a simple example using Slot:

Parent component (App.vue):

<template>
  <div>
    <Slot name="header"></Slot>
    <Slot></Slot>
    <Slot name="footer"></Slot>
  </div>
</template>

Subcomponent (Child.vue):

<template>
  <div>
    <header>
      <Slot name="header"></Slot>
    </header>
    <main>
      <Slot></Slot>
    </main>
    <footer>
      <Slot name="footer"></Slot>
    </footer>
  </div>
</template>

In this example, App.vue defines three Slots, And Child.vue uses these Slots to present different content.
