How to write classes in vue

In Vue, using classes to create components can improve the organization and reusability of code. The steps are as follows: 1. Create a class and register it through Vue.component(); 2. Use components and pass component options through :options; 3. Life cycle hooks can also be implemented in the class, such as created() and mounted(). Advantages: good organization, high maintainability, and strong reusability; Disadvantages: high-level writing, template syntax cannot be used, and options need to be passed through options.

How to write classes in Vue

You can use classes in Vue to organize code and make it easier to maintain and reuse.

1. Create class

<code class="javascript">class MyClass {
  constructor(options = {}) {
    this.options = options
  }
}</code>

2. Register class

<code class="javascript">Vue.component('my-component', MyClass)</code>

3. Use class

<code class="html"><my-component :options="{ foo: 'bar' }" /></code>

Component options

When using component classes, you can use the options parameter to pass component options:

• data：Component data
• props：Component properties
• methods：Component method
• computed：Component computed properties
• watch：Component monitor

Life cycle hook

Component classes can also implement life cycle hooks, for example:

<code class="javascript">class MyClass {
  created() {
    // 组件创建时触发
  }
  mounted() {
    // 组件挂载时触发
  }
  destroyed() {
    // 组件销毁时触发
  }
}</code>

Advantages

Using classes to write Vue components has the following advantages:

• Better code organization
• Higher maintainability and reusability
• Can access all functions and life cycle hooks of Vue

Disadvantages

There are also some disadvantages to using classes:

• is more advanced than functional component writing
• Template syntax cannot be used directly
• Need to pass options Parameter passing options
