What is the subdirectory in vue? how to use?

Vue subdirectory refers to organizing components and other resources into independent subdirectories in a Vue application. This practice helps improve code readability and maintainability.

Vue is a powerful JavaScript framework that allows developers to organize application code by creating components. This requires separating templates, scripts, and styles into separate files, and then assembling the entire application by importing and registering these components. In a large Vue application, if all components are placed in the same directory, the directory structure will be confusing and the code will be difficult to maintain. Therefore, it is becoming increasingly popular to organize components and other related resources into subdirectories.

The following are some common Vue subdirectories:

• components: Directory containing all reusable components.
• layouts: Directory containing application layout components.
• pages: Directory containing all page components.
• assets: Contains all resources used by the application, such as images, fonts, CSS, etc.
• plugins: Directory containing all plug-ins used by the application.

The advantage of using subdirectories is that it can help us better organize the code and avoid overcrowding in the same directory. Additionally, it improves readability and maintainability. For example, when we look for a component in the components directory, we can focus on that directory and ignore files in other directories. This makes maintenance of the code easier.

Let’s take a look at how to use Vue subdirectories. Let's say we have a simple Vue application with two components: Header and Footer. Normally, these two components should be placed in a components directory. However, if we put them into a subdirectory called "layout", the code directory structure will become clearer.

|- src/
|  |- components/
|  |- layouts/
|     |- Header.vue
|     |- Footer.vue
|  |- App.vue
|  |- main.js

In App.vue, we only need to import the Header and Footer components:

<template>
  <div>
    <Header />
    <p>这里是应用程序的内容</p>
    <Footer />
  </div>
</template>

<script>
import Header from './layouts/Header.vue'
import Footer from './layouts/Footer.vue'

export default {
  name: 'App',
  components: {
    Header,
    Footer
  }
}
</script>

At this point, the Header and Footer components have been successfully imported and registered, and we can use them in the application They are.

In summary, Vue subdirectories are a good way to organize code, which allows us to better organize Vue applications. The benefit of using subdirectories is that the code becomes more readable and easier to maintain. Using subdirectories in your Vue application will make it easier for you to organize components as well as other related resources.
