I have to detect user's idle time out in my application. My application is using both native javascript and angular. in my HTML + JavaScript page i implemented below:
<script>
var inactivityTime = function () {
var time;
document.onmousemove = resetTimer;
document.onkeypress = resetTimer;
document.onclick = resetTimer;
document.onwheel = resetTimer;
function callApi() {
alert("Idle for 3 seconds. You can call your api here");
}
function resetTimer() {
clearTimeout(time);
time = setTimeout(callApi, 3000);
// 5 minute = 60000 * 5;
// 1000 milliseconds = 1 second
}
};
window.onload = function() {
inactivityTime();
}
</script>
and it is working as expected.
whereas the same i am using in angular project, angular code is also working but 1 small issue observed please see my angular code first:
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './appponent.html',
styleUrls: ['./appponent.css']
})
export class AppComponent {
title = 'project';
time;
ngOnInit() {
this.inactivityTime();
this.resetTimer();
}
inactivityTime() {
document.onmousemove = this.resetTimer;
document.onkeypress = this.resetTimer;
document.onclick = this.resetTimer;
document.onwheel = this.resetTimer;
}
resetTimer() {
clearTimeout(this.time);
this.time = setTimeout(() => {
alert('Idle for 3 seconds. You can call your api here');
}, 3000);
}
}
the problem i am facing is - on page load even if am doing mouse move / key press, the alert is getting called. after that everything is working as expected. But on page load it is not working.
Requesting help here.
thank you!

Reset to default 8The best approach is to use Angular HostListener decorator and bind it to document:
export class AppComponent {
time: number;
ngOnInit() {
this.resetTimer();
}
@HostListener('document:mousemove')
@HostListener('document:keypress')
@HostListener('document:click')
@HostListener('document:wheel')
resetTimer() {
clearTimeout(this.time);
this.time = setTimeout(() => {
alert('Idle for 3 seconds. You can call your api here');
}, 3000);
}
}
Here is solution in stackblitz
The easiest option would be to use angular-user-idle.
https://www.npmjs./package/angular-user-idle
Include this in app.module.ts: imports: [ .. .. UserIdleModule.forRoot({idle: 3, timeout: 0, ping: 0}) ]
app.ponent.ts
ngOnInit() {
this.userIdle.startWatching();
this.userIdle.onTimerStart().subscribe(count =>{
console.log(count);
if(count == 3){
alert('Idle for 3 seconds. You can call your api here');
this.userIdle.resetTimer();
}
});
}
@HostListener('document:keyup', [])
@HostListener('document:click', [])
@HostListener('document:wheel', [])
@HostListener('document:mousemove', [])
restart() :void{
this.userIdle.resetTimer();
}
