1、打开“文件“ -> “首选项” -> “用户片段”

2、弹出框中选择“新建全局代码片段文件”

3、输入名称，例如“vue.json”，按下“Enter”键，页面跳转至编辑页

模板如下：

{
	// 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": "log",
	  "body": [
		"console.log('$1')",
		"$2"
	  ],
	  "description": "Log output to console"
	},
	"Create VUE template": {
	  "prefix": "vue",
	  "body": [
		"<template>",
		  "  <div>",
		  "    $1",
		  "  </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）",
	

		"",
		"export default {",
		"  name:  '',",
		"  components: {",
		"    $3",
		"  },",
		"  // 定义属性",
		"  data() {",
		"    return {",
		"      $2",
		"    }",
		"  },",
		"  // 计算属性，会监听依赖属性值随之变化",

		"  computed: {},",
		"  // 监控data中的数据变化",
		"  watch: {},",
		"  // 方法集合",
		"  methods: {",
		"    $3",
		"  },",
		"  // 生命周期 - 创建完成（可以访问当前this实例）",
		"  created() {",
		"    $4",
		"  },",
		"  // 生命周期 - 挂载完成（可以访问DOM元素）",
		"  mounted() {",
		"    $5",
		"  },",
		"  beforeCreate() {}, // 生命周期 - 创建之前",
		"  beforeMount() {}, // 生命周期 - 挂载之前",
		"  beforeUpdate() {}, // 生命周期 - 更新之前",
		"  updated() {}, // 生命周期 - 更新之后",
		"  beforeDestroy() {}, // 生命周期 - 销毁之前",
		"  destroyed() {}, // 生命周期 - 销毁完成",
		"  activated() {}, // 如果页面有keep-alive缓存功能，这个函数会触发",
		"}",
		"</script>",
		"",
		"<style scoped>",
		"  $6",
		"</style>"
	  ],
	  "description": "Create VUE template"
	}
  }

4、使用

在新建的vue文件中，输入vue，回车，即可得到自定义模板。
