How to create a custom code template in vscode
本文以Vue的创建为例，不过这个Vue是在HTML中创建的。
初学Vue，我们一般都是在.html文件中引入vue包，然后编写自己的vue代码。
因为我们创建的模板是在.html文件下，所以我们的模板也得是在html.json中来进行编写。
具体方法如下：
1、在Vscode中找到设置 -> 用户代码片段，在输入框内输入html，并点击第一个html.json：
初次输入的话，第一个html.json可能会不带.json后缀，不用管，直接点击html进入即可。
2、进入到html.json页面，这里就是我们编写自己模板的地方
接下里就是编写我们的模板了，我们的模板需要的大致有以下几项：
1、基本的HTML架构。
2、引入Vue包的script路径。
3、一些基本的Vue代码结构。
模板我已经备好了，模板如下：
"Html5-Vue": {
"prefix": "vue",
"body": [
"<!DOCTYPE html>",
"<html lang=\"zh-CN\">\n",
"<head>",
"\t<meta charset=\"UTF-8\">",
"\t<meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\">",
"\t<meta http-equiv=\"X-UA-Compatible\" content=\"ie=edge\">",
"\t<title>Document</title>",
"\t<script src=\"../lib/vue-2.5.17/vue.js\"></script>",
"</head>\n",
"<body>",
"\t<div id=\"app\">$1</div>\n",
"\t<script>",
"\t\tvar vm = new Vue({",
"\t\t\tel: '#app',",
"\t\t\tdata: {},",
"\t\t\tmethods: {}",
"\t\t});",
"\t</script>",
"</body>\n",
"</html>"
],
"description": "快速创建在html5编写的vue模板"
}4、把上面的这个模板拷贝到html.json中即可，当然路径要变成自己的本机路径，其余的地方如果看着不舒服也可以自行更改。
5、保存之后，我们创建一个.html文件，输入vue，回车即可自动生成我们需要的模板了。模板示例图：
必要的说明：
为了防止大家更改模板时出现不必要的错误，我给大家简单说一下模板中的东西：
不要纠结一开头写的："Html5-Vue"，这只是一个模板名字而已。
"prefix": ""这里规定的是触发模板的关键词，我这里规定触发词为vue。
我们的模板都是在"body":[]中编写的。
每一行模板代码都要用双引号""来包括。
如果双引号包括的代码中间也出现了双引号，那么需要用转义字符\转义。
\n意味着换行，\t是制表符，这两个用于生成时模板的缩进，让生成出来的模板便于阅读。
模板中出现的$1代表着光标，它的位置即光标的默认位置，可以有多个光标：$2,$3,$4等。
"description":""双引号包括的是对模板描述，同时也是你在.html页面输入触发词后，智能提示中出现的对触发词的解释。
千万别把Vscode中html.json文件自带的{}覆盖了，只需覆盖注释部分，或直接写到注释下面即可。
