1、在项目中安装nodemon 模块
npm install nodemon --save -dev
2、在package.json中添加以下脚本
（注意配置文件里的 src 路径问题 ）
{ ???"name": "server", ???"version": "0.0.0", ???"scripts": { ?????"postinstall": "tsc -p .", ?????"watch": "tsc -w -p .", ?????"debug": "nodemon --watch ./src --inspect=0.0.0.0:5858 --nolazy ./src/*.js", ?????"docker-debug": "docker-compose up", ?????"start": "node ./src/*.js" ???}, ???"devDependencies": { ?????"@types/node": "^6.0.50", ?????"typescript": "^2.3.2", ?????"nodemon": "^1.11.0" ???}, ???"main": "*.js" ?} ?
3、生成.vscode 文件夹下的 launch.json 和 tasks.json 文件
其中launch.json 如下：
{ ???// Use IntelliSense to learn about possible Node.js debug attributes. ???// Hover to view descriptions of existing attributes. ???// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387 ???"version": "0.2.0", ???"configurations": [ ???????{ ???????????"type": "node", ???????????"request": "launch", ???????????"name": "nodemon", ???????????"protocol": "auto", ???????????"preLaunchTask": "tsc-watch", ???????????"runtimeExecutable": "npm", ???????????"env": { ???????????????"NODE_ENV": "dev" ???????????}, ???????????"restart": false, ???????????"console": "integratedTerminal", ???????????"internalConsoleOptions": "neverOpen", ???????????"outFiles": [ ???????????????"${workspaceFolder}/src/js/test.js" ???????????] ???????} ???]}
tasks.json 如下：
{ ?????"version": "0.1.0", ?????"tasks": [ ?????????{ ?????????????"taskName": "tsc-watch", ?????????????"command": "npm", ?????????????"isShellCommand": true, ?????????????"args": [ ?????????????????"run", ?????????????????"watch" ?????????????], ?????????????"isBackground": true, ?????????????"isBuildCommand": true, ?????????????"problemMatcher": "$tsc-watch", ?????????????"showOutput": "always" ?????????} ?????] ?} ?按键F5 或者 点击菜单 任务-运行任务 点击tsc-watch 即可！
