mac webstorm 使用typescript 和配置自动编辑 typescript

mac webstorm 使用typescript 和配置自动编译

安装typescript
配置tsconfig.js(ts配置文件)
配置tsconfig文件
修改webstorm的配置
编译效果

【mac webstorm 使用typescript 和配置自动编辑】
安装typescript 打开终端使用npm的前提是安装了node

npm install -g typescript

配置tsconfig.js(ts配置文件) 在所要编译的ts所在的目录中打开终端输入tsc --init ，可以自动生成tsconfig.js

tsc --init

配置tsconfig文件

修改outDir的参数，设置成你需要的ts文件编译后的输出目录
tsconfig.json的配置可以参照这里：
http://www.typescriptlang.org/docs/handbook/tsconfig-json.html
修改webstorm的配置

点击webstorm ? Preferences(或者command+,快捷键打开)
