How to import the Vue framework into a mini program

Today with the increasing development of mobile Internet, small programs have become an indispensable part of users' lives. As developers, we not only need to understand the conventional development of small programs, but also need to constantly learn new technologies and frameworks to improve development efficiency and the quality of small programs. The Vue framework is one of the recommended technologies.

Vue.js is a lightweight MVVM framework that can quickly develop single-page applications (SPA), and using Vue in small programs can greatly improve development efficiency and code reusability. This article will introduce how to import the Vue framework into a mini program.

1. Install the Vue framework

First, we need to install the Vue framework in the mini program. You can install it via npm or download Vue.js manually. The following introduces the specific operations of the npm installation method:

1. Open the command line tool and enter the root directory of the mini program project;
2. Install Vue.js

npm install vue --save

3. Install the Vue framework "mpvue" of the mini program

npm install mpvue --save-dev

2. Create the Vue page

After installing the Vue framework, we need to create the Vue page in the mini program project .

1. In the pages directory of the mini program, create a new vue folder to store Vue page files;
2. In the vue folder, create a new .vue file for Write Vue page code. For example, we created a new .vue file named "index.vue";
3. In the index.vue file, write the Vue code. Here is a sample code for your reference:

<template>
  <div>
    <h1>{{ message }}</h1>
    <button @click="changeMessage">修改信息</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      message: '欢迎来到Vue小程序'
    }
  },
  methods: {
    changeMessage() {
      this.message = '修改信息成功'
    }
  }
}
</script>

<style scoped>
h1 {
  color: #f00;
  font-size: 16px;
}
</style>

3. Register Mini Program Page

We have created a Vue page, and next we need to register it as a mini program page. .

1. In the main.js of the mini program project, import mpvue and Vue.js

import Vue from 'vue'
import Mpvue from 'mpvue'
import MpvueRouter from 'mpvue-router'

Vue.use(Mpvue)
Vue.use(MpvueRouter)

2. Import our index.vue component

import index from './pages/vue/index.vue'

3. Register the index.vue page as the page of the mini program in the routing configuration of the mini program project

const routes = [
  {
    path: '/pages/vue/index',
    component: index
  }
]

4. Write the mini program entry page

We have completed the Vue page registration, and next we need to write the entry page of the mini program.

1. In the main.js of the mini program project, define the App of the mini program

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

const app = new Vue({
  router,
  ...App
})
app.$mount()

2. After completing the above steps, we can access it in the mini program Registered Vue page.

Here is a summary of the entire process of importing the Vue framework:

1. Install the Vue framework;
2. Create a Vue page and write Vue code;
3. Register mini program page;
4. Write mini program entry page.

The above is all about how to import the Vue framework into a small program. I hope it will be helpful to everyone. In development, the rational use of technologies and frameworks can not only improve development efficiency, but also better improve the quality and user experience of mini programs.
