找到文件、首选项、用户片段、 输入vue   会自动到vue.json页面中，

然后将以下代码复制、粘贴、保存。

回到以点vue结尾的文件 输入 vv 点击tab就会自动生成以下模板

{

    // 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"

    // }
