How to use Vue for multi-page application development?

Vue is a very popular front-end framework that can help us build high-performance, maintainable single-page applications. However, sometimes we need to build multi-page applications, which requires the use of Vue's multi-page application development model. This article will introduce how to use Vue for multi-page application development.

1. The difference between multi-page applications and single-page applications

In a single-page application, all content is dynamically generated through JavaScript, and there is only one HTML file. As the user interacts with the application, only components and routes need to be updated without reloading the entire application.

In a multi-page application, each page has its own HTML file. Every time a page is opened, the browser will load a new HTML file. This means that multi-page apps have more content to load, but they are better suited for situations where SEO is required, or where more optimization of a single page is required.

2. Use Vue CLI to create multi-page applications

We can use Vue CLI to create multi-page applications. Vue CLI is an officially supported scaffolding tool that provides a standardized development environment and build process. Here is a simple example:

First, install the Vue CLI.

npm install -g @vue/cli

Then, create a multi-page application.

vue create my-app --preset multi-page

This will create a new project called "my-app" and use the Vue CLI's multi-page preset. This preset will automatically generate a "src/pages" directory containing two sample pages.

3. Configuring multi-page applications

Next, we need to configure Vue CLI to support multi-page applications. Open the "vue.config.js" file and add the following content to the file:

module.exports = {
  pages: {
    index: {
      entry: 'src/pages/index/main.js',
      template: 'src/pages/index/index.html',
      filename: 'index.html'
    },
    about: {
      entry: 'src/pages/about/main.js',
      template: 'src/pages/about/about.html',
      filename: 'about.html'
    }
  }
}

Here we define two pages: index and about, corresponding to "src/pages/index" and "src" respectively Entry files and template files in the /pages/about" directory. Each page needs to define an entry file and a template file. The entry file is the main entry point of the program, and the template file defines the structure and style of the page.

4. Creating page components

Now we need to create the components for each page. In the sample application, we can create these components under the "src/pages/index/components" and "src/pages/about/components" directories. For example, you can create a "Header" component and a "Footer" component and use them in every page. Here is a simple example:

<template>
  <div>
    <Header />
    <h1 id="title">{{ title }}</h1>
    <p>{{ message }}</p>
    <Footer />
  </div>
</template>

<script>
import Header from '@/components/Header.vue'
import Footer from '@/components/Footer.vue'

export default {
  components: {
    Header,
    Footer
  },
  data() {
    return {
      title: 'About',
      message: 'This is the about page.'
    }
  }
}
</script>

5. Building and running the application

Now we have completed the configuration and component creation of the multi-page application. Next, we need to build and run the application. Run the following command to build the application:

npm run build

This will generate an "index.html" and an "about.html" file in the "dist" directory. In order to start a development server and view the application, run the following command:

npm run serve

This will start a development server and open the browser to view the multi-page application. You can access the application using the following URL:

• http://localhost:8080/index.html
• http://localhost:8080/about.html

6. Summary

Using Vue for multi-page application development allows us to manage and optimize each page more effectively. Using Vue CLI can help us quickly create the basic architecture of a multi-page application. By configuring the "vue.config.js" file and creating page components, you can build a feature-rich application.
