angular-user-idle

Service for Angular 4 to detect and control of user's idle.

Installation

npm install angular-user-idle

In app.module.ts:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { UserIdleModule } from 'angular-user-idle';

import { AppComponent } from './app.component';

@NgModule({
  imports: [
    BrowserModule,
    UserIdleModule
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule {}

Usage

You should init user idle service in one of core component or service of your app, for example login.component.ts:

import { Component, OnInit } from '@angular/core';
import { UserIdleService } from 'angular-user-idle';

@Component({
  templateUrl: './login.component.jade'
})
export class LoginComponent implements OnInit {

  readonly googlePlayLink: string;
  readonly appStoreLink: string;

  constructor(private userIdle: UserIdleService) {
  }

  ngOnInit() {
    //Start watching for user inactivity.
    this.userIdle.startWatching();
    
    // Start watching when user idle is starting.
    this.userIdle.onTimerStart().subscribe(count => console.log(count));
    
    // Start watch when time is up.
    this.userIdle.onTimeout().subscribe(() => console.log('Time is up!'));
  }

  stop() {
    this.userIdle.stopTimer();
  }

  stopWatching() {
    this.userIdle.stopWatching();
  }

  startWatching() {
    this.userIdle.startWatching();
  }

  restart() {
    this.userIdle.resetTimer();
  }
}

API

startWatching(idle?: number, timeout?: number, ping?: number): void;

Start user idle service and configure it.

Optionally you can set time for idle, timeout and ping in seconds. Default values: idle is 600 (10 minutes), timeout is 300 (5 minutes) and ping is 120 (2 minutes).

onTimerStart(): Observable<number>

Fired when timer is starting and return observable (stream) of timer's count.

onTimeout(): Observable<boolean>;

Fired when time is out and id user did not stop the timer.

stopTimer()

Stop timer.

resetTimer()

Reset timer after onTimeout() has been fired.

stopWatching()

Stop user idle service.

startWatching()

Service logic:

• User is inactive for 10 minutes
• onTimerStart() is fire and return countdown for 5 minutes
• If user did not stop timer by stopTimer() then time is up and onTimeout() is fire.
