angular-user-idle

Service for Angular 6+ to detect and control of user's idle.

npm version

Important

This library was written for needs of my corporate project and this library compiles and works (Angular 6) very well and as I expected. Unfortunately, I don't have necessary time to maintenance my library as fast as you can expected. I have a plan to review my code to try to fix a bugs that was reported by other users but I don't know when I do it. Thank for your understanding.

To use this library in Angular 5.x use angular-user-idle ver. 1.1.0.

Demo

angular-user-idle.rednez.com

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,
    
    // 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).
    UserIdleModule.forRoot({idle: 600, timeout: 300, ping: 120})
  ],
  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();
  }
}
About ping

Please note that ping is used if you want to perform some action periodically every n-minutes in lifecycle of timer (from start timer to timeout).

For example, if you want to make a request to refresh token every 2 minutes you set ping to 120 and subscribe to ping's observable like this:

this.idle.ping$.subscribe(() => console.log("PING"));

The main schema will be as follow:

|–– 2m (ping)––4m (ping) ––6m (ping)...-– 10m (user idle detected, start timer for 5 min) –- 12m (ping) –– 14m (ping) –– 15m (time is out)|

If you don't use a ping just set ping to any value (not null) and just ignore it.

API

startWatching(): void;

Start user idle service and configure it.

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.

setConfigValues({idle, timeout, ping})

Set config values after module was initialized.

setCustomActivityEvents(customEvents: Observable<any>): void

Set custom activity events after module was initialized.

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.
You can’t perform that action at this time.
