首先安装打字稿， npm install -g typescript@2.0.0
第二次安装ng-idle
npm install --save @ ng-idle / core @ ng-idle / keepalive angular2-moment
在app.module.ts中导入ng-idle从<@ ng-idle / keepalive'导入{NgIdleKeepaliveModule};

imports: [
NgIdleKeepaliveModule,
IonicModule.forRoot(MyApp)  ],

在您要使用的typescript文件中声明空闲。 e.g：home.ts

import { NgIdleKeepaliveModule } from '@ng-idle/keepalive';
export class HomePage {

idleState = 'Not started.';
timedOut = false;
min:any;
sec;any;
constructor(public navCtrl: NavController,private barcodeScanner: BarcodeScanner,public idle: Idle) { }


 ionViewDidLoad() {
this.idle.setIdle(5);  //after 5 sec idle
this.idle.setTimeout(5*60);  //5min countdown
this.idle.setInterrupts(DEFAULT_INTERRUPTSOURCES);

this.idle.onIdleEnd.subscribe(() => this.idleState = 'No longer idle.');
this.idle.onTimeout.subscribe(() => {
  this.idleState = 'Timed out!';
  this.timedOut = true;
  this.navCtrl.pop();  //go to logout page after 5 min idle.
});
this.idle.onIdleStart.subscribe(() => this.idleState = 'You\'ve gone idle!');
this.idle.onTimeoutWarning.subscribe((countdown) => {


    var data=countdown/60;
    this.min=data.toString().split('.')[0];
    this.sec=     parseFloat(0+'.'+data.toString().split('.')[1])*60;
    this.sec=  (Math.round(this.sec * 100) / 100);
    console.log(countdown)

  this.idleState = 'You'll logout in ' + this.min+' min ' +this.sec+'  seconds!';
});
   this.reload();
  }
  reload() {
    this.idle.watch();
    this.idleState = 'Started.';
    this.timedOut = false;
  }
}

在home.html中

 <p><strong>{{idleState}}</strong></p>
<button (click)="reset()" *ngIf="timedOut">Reload</button>

它可以计算到5分钟。

如果您使用的是<

npm install --save @ng-idle/core@2.0.0-beta.15
npm install --save @ng-idle/keepalive@2.0.0-beta.15

如果您使用的是角度v.6，请使用

npm install --save @ng-idle/core
npm install --save @ng-idle/keepalive
