Creating Reusable Templates in Vue.js

Hello, students! Welcome to Lesson 1 of Templates in Vue.js. Today, we will learn about reusable templates.

Templates are the way to define the structure and content of a Vue.js component.

Reusable templates are templates that can be used in different Vue.js components.

Why Use Reusable Templates?

There are several advantages to using reusable templates:

• Code Reduction: Reusable templates can help reduce the amount of code you need to write.
• Improved Readability: Reusable templates can make your code more readable and easier to maintain.
• Increased Flexibility: Reusable templates can help you create more flexible and adaptable applications.

How to Create Reusable Templates

To create a reusable template, you can use the <slot> directive.

The <slot> directive allows you to define an area in your template that can be filled by another template.

For example, let’s consider the following template:

<template>
  <div>
    <slot name="content"></slot>
  </div>
</template>

This template defines an area called content that can be filled by another template.

To use a reusable template, you can use the <component> directive.

The <component> directive allows you to embed a component in another template.

For example, let’s consider the following template:

<template>
  <div>
    <component :is="'my-component'"></component>
  </div>
</template>

This template embeds the my-component component in the template.

To make the my-component component fill the content area of the reusable template, you can set the component’s name property to content.

For example, let’s consider the following code:

export default {
  components: {
    MyComponent: {
      template: `
        <div>
          <slot name="content"></slot>
        </div>
      `,
    },
  },
};

This code defines a component named MyComponent that has an area called content.

Now, we can use the MyComponent component in the reusable template:

<template>
  <div>
    <component :is="'my-component'"></component>
  </div>
</template>

This template will display the following:

<div>
  <div>
    <slot name="content"></slot>
  </div>
</div>

Challenge

Here’s a challenge for you:

• Create a reusable template for a button. The template should have an area for the button text and an area for the button image.

Good luck!

Tip

You can use the following structure for the reusable button template:

<template>
  <div>
    <slot name="text"></slot>
    <slot name="image"></slot>
  </div>
</template>

You can use the name properties of the slots to specify the names of the template areas.

In the next topic, we will learn how to structure and organize templates efficiently.
