How to improve application development efficiency and performance through Vue's single file component

Introduction:
In front-end development, Vue has become one of the most popular JavaScript frameworks. Vue's single-file component is a Vue-based development model that encapsulates a component's style, template, and logic code into a separate file, which can improve code maintainability and development efficiency. This article will introduce how to use Vue's single-file components to improve application development efficiency and performance, and illustrate it through code examples.

1. What is Vue's single-file component
Vue's single-file component is a special file format with a .vue extension that contains the component's template, style and JavaScript code. Single-file components allow developers to write component-related code in the same file, organizing code more clearly and conveniently.

2. How to create and use a single-file component

1. Create a single-file component
   Create a new file in the src directory of the project and name it HelloWorld.vue (sample component name), and write the following code in this file:

   <template>
     <div>
    <h1>{{ title }}</h1>
    <p>{{ message }}</p>
     </div>
   </template>
   
   <script>
   export default {
     data() {
    return {
      title: 'Hello, Vue!',
      message: 'This is a single file component.'
    }
     }
   }
   </script>
   
   <style scoped>
   h1 {
     color: blue;
   }
   p {
     font-size: 14px;
   }
   </style>

   In the above code, the
