{
// Place your 全局 snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and
// description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope
// is left empty or omitted, the snippet gets applied to all languages. 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": {
// "scope": "javascript,typescript",
// "prefix": "log",
// "body": [
// "console.log('$1');",
// "$2"
// ],
// "description": "Log output to console"
// }
"Print to console": {
"scope": "javascript,typescript",
"prefix": "express", // 输入什么内容可以触发当前代码片段
"body": [ // 当前 代码段所想展示的内容， 每一行显示的内容都是一个字符串
"// 导入 express 模块", // 每一行结束的时候， 都要有一个逗号进行分割，
"const express = require('express')",
" ", // 如果你想在你生成的代码中有一个空行，那么你必须有一个空的字符串作为占位
"// 创建 express 的服务器实例",
"const app = express()",
" ",
"",
"// 启动当前服务器",
"app.listen(80, (req, res) => {",
" console.log('http://127.0.0.1')",
"})"
],
"description": "Log output to console" // 这是个描述信息
}
