In today's rapidly developing information society, mobile applications are becoming more and more popular, and vue, as an easy-to-use and efficient front-end framework, is also used in mobile application development. Has been widely used. So, next we will introduce how to use vue to make a mobile terminal.

1. Install vue-cli

Before starting to use vue for mobile front-end development, we need to install vue-cli first. Enter the following command in the command line window:

npm install -g vue-cli

After the installation is complete, we can use vue-cli to create a project.

2. Create a project

Enter the following command in the command line window:

vue init webpack my-project

where, my-project is The project name can be freely named according to your own needs.

3. Install dependencies

Enter the project directory, and then enter the following command in the command line window:

npm install

This command will install all the project dependencies All dependencies required.

4. Write code

Before writing code, we need to build a simple page as a display, which includes an input box, a button and a list. After the user enters the content, click the button to Content is added to the list.

To use vue, we need to introduce vue into main.js first:

import Vue from 'vue'

Then, add a div tag in index.html ：

Next, we need to write the component and mount it on the div tag.

First, create a components folder in the src directory, and then create a HelloWorld.vue file under the folder, the code is as follows:

<script><br/>export default {<br/> name: 'HelloWorld',<br/> data () {</script>

return {
  content: '',
  list: []
}

},
methods: {

add() {
  this.list.push(this.content)
  this.content = ''
}

}
}

The content in the template tag Represents the layout of the component, including an input box, a button and a list. At the same time, the v-for instruction is used in the list to traverse the data and render it on the page.

The content in the script tag represents the logic of the component, including two objects, data and methods. Two attributes, content and list, are defined in the data object, which are used to store user input content and list data; the methods object An add method is defined in which is used to add the content entered by the user to the list and clear the input box.
