1、安装一个插件，识别vue文件

2、新建代码片段

Copy

管理-> 首选项 -> 用户代码片段 -> (新建代码片段取名vue.json）
新建代码片段这块可以直接往下找就能找到vscode上带的vue.json

3、在vue.json里写下自己想要生成的vue模版

Copy

{
	// Place your snippets for vue here. Each snippet is defined under a snippet name and has a prefix, body and 
	// description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
	// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
	// same ids are connected.
	// Example:
	"Print to console": {
		"prefix": "vue",
		"body": [
			//"<!-- $1 -->",
			"<template>",
			"    <div>",
			"    </div>",
			"</template>",
			"",
			"<script>",
			"export default {",
			"    data() {",
			"        return {",
			"            ",
			"        }",
			"    },",
			"    //生命周期 - 创建完成（访问当前this实例）",
			"    created() {",
			"        ",
			"    },",
			"    //生命周期 - 挂载完成（访问DOM元素）",
			"    mounted() {",
			"        ",
			"    }",
			"}",
			"</script>",
			"<style scoped>",
			"/* @import url(); 引入css类 */",
			"$4",
			"</style>"
		],
		"description": "Log output to console"
	}
}

4、粘贴以上代码复制到vue.json里效果如下

Copy

此处说明一下："prefix": "vue", 就是快捷键，（vue名称可随意修改）
新建vue文件，输入vue 按键盘的tab件生成vue模版
