How to use Vue technology for mobile development

With the rapid development of the mobile Internet, the development of mobile applications has become more and more important. As a lightweight, high-performance front-end framework, Vue.js is widely used in mobile development. This article will introduce how to use Vue technology for mobile development and give specific code examples.

1. Preparation

1. Install Vue.js and Vue CLI

Before starting to use Vue for mobile development, we first need to install Vue .js and Vue CLI. It can be installed through npm or yarn. For specific installation methods, please refer to the documentation on the Vue official website.

2. Create project

After installing Vue.js and Vue CLI, we can use Vue CLI to quickly create a Vue project. Open the command line tool and execute the following command:

vue create my-project

where my-project is the project name, which can be named according to the actual situation.

2. Develop mobile interface

1. Use Vant UI component library

Vant is a Vue-based mobile UI component library with rich Components and styles can quickly develop beautiful mobile interfaces. We can install Vant through npm or yarn, and then introduce and use it in the main.js file:

import Vue from 'vue'
import Vant from 'vant'
import 'vant/lib/index.css'

Vue.use(Vant)

. After that, we can use various components provided by Vant in the project.

2. Development page

After creating the Vue project, we can create a pages directory in the src directory to store the components of each page. For example, we create a Home.vue in the pages directory and write the following code:

<template>
  <div class="home">
    <h1>欢迎使用Vue移动端开发</h1>
  </div>
</template>

<script>
export default {
  mounted() {
    console.log('页面加载完成')
  }
}
</script>

<style scoped>
.home {
  text-align: center;
  padding-top: 100px;
  font-size: 20px;
}
</style>

Introduce and use the Home component in App.vue:

<template>
  <div id="app">
    <router-view/>
  </div>
</template>

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

<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

3. Routing configuration

1. Install vue-router

Before using vue-router for routing configuration, we need to install vue-router first. Execute the following command:

npm install vue-router --save

2. Create routing configuration file

In the src directory, create a router directory, then create an index.js file in the router directory, and write The following code:

import VueRouter from 'vue-router'
import Home from '@/pages/Home.vue'

const routes = [
  {
    path: '/',
    component: Home
  }
]

const router = new VueRouter({
  mode: 'history',
  base: process.env.BASE_URL,
  routes
})

export default router

3. Use routing configuration in main.js

Introduce and use router configuration in main.js:

import Vue from 'vue'
import App from './App.vue'
import router from './router'

Vue.config.productionTip = false

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')

IV. Network request

1. Install axios

Before using axios to make network requests, we need to install axios first. Execute the following command:

npm install axios --save

2. Create a network request encapsulation file

In the src directory, create an api directory, and then create a request.js file in the api directory, Write the following code:

import axios from 'axios'

const instance = axios.create({
  baseURL: 'http://api.example.com',
  timeout: 5000
})

instance.interceptors.request.use(
  config => {
    // 在此处可以添加token等认证信息
    return config
  },
  error => {
    return Promise.reject(error)
  }
)

instance.interceptors.response.use(
  response => {
    // 在此处可以对返回的数据进行处理
    return response.data
  },
  error => {
    return Promise.reject(error)
  }
)

export default instance

3. Use network requests in components

In components that need to send network requests, you can introduce axios through import and encapsulate it using Axios example:

import request from '@/api/request'

export default {
  methods: {
    fetchData() {
      request.get('/api/data').then(res => {
        console.log(res)
      }).catch(error => {
        console.log(error)
      })
    }
  }
}

The above are some basic steps and sample codes for mobile development using Vue technology. Hope this helps!
