Vue Development Experience Summary: Practice in Solving SEO and Search Engine Optimization

In the current era of rapid development of mobile Internet and Web technology, search engines are still the most powerful on the Internet. One of the main ways to obtain information. For websites that need to gain high exposure in search engines, SEO (Search Engine Optimization) is an essential task. So, for web development projects using Vue technology, how to achieve SEO and search engine optimization?

Vue is a progressive JavaScript framework for building user interfaces. It is lightweight, efficient, easy to use, easy to use, etc., and has a wide range of applications. However, because it uses front-end rendering technology, it has certain limitations for search engine crawling. Therefore, for websites developed by Vue, it is particularly important to implement SEO and search engine optimization.

1. Meta tag in Vue

Meta tag refers to the tag that provides metadata in the HTML document. By adding the Meta tag in the

<template>
  <div>
    <h1>這是Vue項目的主頁</h1>
  </div>
</template>

<script>
  export default {
    name: 'home',
    metaInfo: {
      title: 'Vue項目',
      meta: [{
        hid: 'description',
        name: 'description',
        content: '這是一篇Vue項目的主頁'
      }]
    }
  }
</script>

Among them, metaInfo is the method of adding Meta tags provided by Vue, where title and meta represent the web page title and meta information respectively, and can be modified as needed.

2. Asynchronous data acquisition in Vue

Vue implements front-end rendering through its own virtual DOM technology, making the update of the user interface faster and smoother. However, for search engines, because they cannot recognize the asynchronous rendering process in Vue, asynchronous data acquisition in the Vue project will have an impact on SEO. To do this, we can use the asyncData method provided by Vue to implement the process of obtaining asynchronous data before the front-end rendering is completed.

<template>
  <div>
    <h1>{{ title }}</h1>
  </div>
</template>

<script>
  export default {
    name: 'news',
    asyncData ({ params, service }) {
      return service.getNews(params.id)
    },
    data () {
      return {
        title: ''
      }
    },
    created () {
      this.title = this.$route.params.title
    }
  }
</script>

In the above code, asyncData is the method provided by Vue, in which asynchronous data can be obtained by calling the service.getNews() method. After obtaining the data, it can be rendered in the user interface. In this way, the accuracy of SEO can be guaranteed and the user experience can be improved.

3. Server-side rendering in Vue

Vue provides a server-side rendering (SSR) method, which can render Vue components on the server side, and then Return the rendering results to the client and display them to the user, which can solve the problem of the impact of front-end rendering on SEO. In Vue, the method of using server-side rendering is also very simple. You only need to use the VueSSRServerPlugin plug-in and VueSSRClientPlugin plug-in provided by Vue to render the Vue components on the server side and client side respectively.

// webpack.server.config.js
const VueSSRServerPlugin = require('vue-server-renderer/server-plugin')

module.exports = {
  target: 'node',
  entry: './src/entry-server.js',
  output: {
    filename: 'server-bundle.js',
    libraryTarget: 'commonjs2'
  },
  plugins: [
    new VueSSRServerPlugin()
  ]
}

// webpack.client.config.js
const VueSSRClientPlugin = require('vue-server-renderer/client-plugin')

module.exports = {
  entry: './src/entry-client.js',
  plugins: [
    new VueSSRClientPlugin()
  ]
}

In the above code, webpack.server.config.js and webpack.client.config.js are the configuration files for server-side rendering and client-side rendering respectively, among which VueSSRServerPlugin and VueSSRClientPlugin are the services provided by Vue respectively. Side rendering plug-in. By using these plug-ins, we can easily implement server-side rendering of Vue projects, thereby improving SEO effects.

To sum up, Vue, as a front-end progressive framework, has certain limitations in SEO. However, by adding Meta tags, asynchronous data acquisition and server-side rendering, we can well solve the SEO and search engine optimization problems of the Vue project, thereby achieving better user experience and business results.
