一、安装一个插件，识别vue文件

二、文件–>首选项–>用户代码片段–>搜索框中输入html.json

将下面代码加进去，要在之前的代码后面加逗号

"Print to console": {
  "prefix": "vue",
  "body": [
    "<!-- $1 -->",
    "<template>",
    "<div class='$2'>$5</div>",
    "</template>",
    "",
    "<script>",
    "//这里可以导入其他文件（比如：组件，工具js，第三方插件js，json文件，图片文件等等）",
    "//例如：import 《组件名称》 from '《组件路径》';",
    "",
    "export default {",
    "\t//import引入的组件需要注入到对象中才能使用",
    "\tcomponents: {},",
    "\tdata() {",
    "\t//这里存放数据",
    "\treturn {",
    "",
    "\t};",
    "\t},",
    "\t//监听属性 类似于data概念",
    "\tcomputed: {},",
    "\t//监控data中的数据变化",
    "\twatch: {},",
    "\t//方法集合",
    "\tmethods: {",
    "",
    "\t},",
    "\t//生命周期 - 创建完成（可以访问当前this实例）",
    "\tcreated() {",
    "",
    "\t},",
    "\t//生命周期 - 挂载完成（可以访问DOM元素）",
    "\tmounted() {",
    "",
    "\t},",
    "\tbeforeCreate() {}, //生命周期 - 创建之前",
    "\tbeforeMount() {}, //生命周期 - 挂载之前",
    "\tbeforeUpdate() {}, //生命周期 - 更新之前",
    "\tupdated() {}, //生命周期 - 更新之后",
    "\tbeforeDestroy() {}, //生命周期 - 销毁之前",
    "\tdestroyed() {}, //生命周期 - 销毁完成",
    "\tactivated() {}, //如果页面有keep-alive缓存功能，这个函数会触发",
    "}",
    "</script>",
    "<style scoped>",
    "//@import url($3); 引入公共css类",
    "$4",
    "</style>"
  ],
  "description": "Log output to console"
