Dynamic components for advanced use of Vue

Today I want to talk to you about Vue dynamic components.

First, let's understand what Vue dynamic components are. Vue dynamic components allow you to switch components dynamically instead of hardcoding them in a fixed static component. Vue dynamic components better make your code repeatable and enhance its maintainability.

So, next we will demonstrate how to use Vue dynamic components.

First, let's create a simple template that toggles two different components:

<template>
  <div>
    <button @click="showComponent = 'component1'">组件1</button>
    <button @click="showComponent = 'component2'">组件2</button>
    <component :is="showComponent"></component>
  </div>
</template>

The implementation of this code is relatively simple. We take advantage of Vue's built-in components <component>and take advantage of its :isproperties, which allow us to dynamically bind components to different components. At the same time, we used two buttons to switch to different components. Now we are going to define these two components.

<template>
  <div>
    <h2>这是组件1</h2>
  </div>
</template>

<template>
  <div>
    <h2>这是组件2</h2>
  </div>
</template>

Here are our two simple components that say "This is component 1" and "This is component 2". Next, we need to register these two components in our Vue instance and set the value of the default showComponentproperty to the "component1" component.

<template>
  <div>
    <button @click="showComponent = 'component1'">组件1</button>
    <button @click="showComponent = 'component2'">组件2</button>
    <component :is="showComponent"></component>
  </div>
</template>

<script>
  import Component1 from './Component1.vue';
  import Component2 from './Component2.vue';

  export default {
    data() {
      return {
        showComponent: 'component1'
      }
    },
    components: {
      Component1,
      Component2
    }
  }
</script>

Now you can run the code and see that when the button is clicked, Vue dynamically assigns the component to the <component>. In a real application, dynamic components can be very useful, especially when you have some common properties or methods, which you can define in a common component and then dynamically add to other components.

In general, Vue dynamic components are a very useful feature, this article just briefly introduces its basic usage. If you want to learn more about Vue dynamic components, you can check the relevant instructions in the official Vue documentation.

I hope this technical blog was helpful and brought you some joy. Thanks!
