写在package.json 里的

监控 dist/teaching 目录中的js文件，如有变化时执行node命令

"dev:start": "nodemon --watch dist/teaching.js --exec node ./dist/teaching/1ClassDecorator.js"

合并启动

"start": "concurrently npm:dev:*"

解决ts编译装饰器类时出现的bug

"tsc": "tsc src/teaching/1ClassDecorator.ts --target ES5 -w --experimentalDecorators"

后面会用到这个，先配上

"ctrl": "ts-node src/controller/HomeController.ts", "beginapp": "nodemon --watch src/ -e ts --exec ts-node ./src/expressapp.ts"

"cmd": "npx ts-node ./src/10-3/2ClassDecorator.ts"
