ts+node+vscode开发环境配置

ts源文件

// index.ts
const str:string = '1';
console.log(str);

编译ts文件 生成js文件

1
2
tsc index.ts
node index.js

生成配置文件

"rules": {
"no-var-keyword": true,

自动编译ts文件 && 执行js文件

  • 有配置文件之后,cmd+shift+b 选择监视
  • nodemon index.js

代码规范约束

  • npm i tslint -D
  • ./node_modules/.bin/tslint init
