支持本地安装(Local Installation)

$ npm install ko-port

支持全局安装(Global Installation)

$ npm install ko-port -g

支持API

• asyncPort(port: number): Promise<any>

识别指定port是否可用，否则递归加1，返回有效port

样例:

var koport = require('ko-port');

koport.asyncPort(3000)
  .then((port) => {
      // 返回有效port
      http.createServer(app).listen(port, function () {
          console.log('listening on port ', port)
      })
  })
  .catch((err) => {
      // 返回err
  });

• killPort(port: number): Promise<any>

杀死指定的port占用进程

样例:

var koport = require('ko-port');

koport.killPort(3000)
  .then(() => {
      // success
  })
  .catch((err) => {
      // error
  });

如果是全局(Global)安装：

$ koport 3000
