Typescript - How to call a function in every 10 seconds in Angular?

In Angular, you can use the setInterval function to call a function at regular intervals. To call a function every 10 seconds, you can do the following:

  1. Import the necessary modules and services.
  2. Use the setInterval function to call your desired function.
  3. Make sure to clear the interval when the component is destroyed to avoid memory leaks.

Here's an example:

import { Component, OnInit, OnDestroy } from '@angular/core';

@Component({
  selector: 'app-your-component',
  template: '<p>Your component content here</p>',
})
export class YourComponent implements OnInit, OnDestroy {
  private intervalId: any;

  ngOnInit() {
    // Call your function every 10 seconds
    this.intervalId = setInterval(() => {
      this.yourFunction();
    }, 10000); // 10000 milliseconds = 10 seconds
  }

  ngOnDestroy() {
    // Clear the interval when the component is destroyed
    if (this.intervalId) {
      clearInterval(this.intervalId);
    }
  }

  yourFunction() {
    // Your function logic here
    console.log('Function called every 10 seconds');
  }
}

Replace YourComponent and yourFunction with your actual component name and the function you want to call. This example sets up an interval that triggers the function every 10 seconds and clears the interval when the component is destroyed to avoid memory leaks.

Examples

  1. "Angular setInterval for calling a function every 10 seconds"

    // Code
setInterval(() => {
    this.myFunction();
}, 10000);

    Description: Use setInterval to repeatedly call the specified function (myFunction in this case) every 10 seconds (10000 milliseconds).

  2. "Angular RxJS interval for calling a function every 10 seconds"

    // Code
import { interval } from 'rxjs';

interval(10000).subscribe(() => {
    this.myFunction();
});

    Description: Use RxJS interval to create an observable that emits a value every 10 seconds and subscribe to it to call the function.

  3. "Angular ngZone.runOutsideAngular for calling a function every 10 seconds"

    // Code
import { NgZone } from '@angular/core';

constructor(private ngZone: NgZone) {}

this.ngZone.runOutsideAngular(() => {
    setInterval(() => {
        this.ngZone.run(() => {
            this.myFunction();
        });
    }, 10000);
});

    Description: Use ngZone.runOutsideAngular to run the setInterval outside the Angular zone and manually re-enter the zone when calling the function.

  4. "Angular setTimeout for recursive function every 10 seconds"

    // Code
myRecursiveFunction() {
    this.myFunction();
    setTimeout(() => {
        this.myRecursiveFunction();
    }, 10000);
}

    Description: Use setTimeout within a recursive function to call the specified function every 10 seconds.

  5. "Angular ng-repeat for calling a function every 10 seconds"

    // Code
ngAfterViewInit() {
    this.repeatFunctionEvery(10000);
}

repeatFunctionEvery(milliseconds: number) {
    setTimeout(() => {
        this.myFunction();
        this.repeatFunctionEvery(milliseconds);
    }, milliseconds);
}

    Description: Use setTimeout in combination with a recursive function to repeatedly call the specified function every 10 seconds.

  6. "Angular ngFor for calling a function every 10 seconds"

    // Code
ngAfterViewInit() {
    this.callFunctionEvery(10000);
}

callFunctionEvery(milliseconds: number) {
    setInterval(() => {
        this.myFunction();
    }, milliseconds);
}

    Description: Use setInterval to repeatedly call the specified function every 10 seconds.

  7. "Angular custom service with interval for calling a function every 10 seconds"

    // Code
import { Injectable } from '@angular/core';
import { interval } from 'rxjs';

@Injectable({
    providedIn: 'root',
})
export class MyService {
    constructor() {
        interval(10000).subscribe(() => {
            this.myFunction();
        });
    }

    myFunction() {
        // Function implementation
    }
}

    Description: Create a custom service with RxJS interval to call the function every 10 seconds.

  8. "Angular ngZone.runOutsideAngular with RxJS interval for calling a function every 10 seconds"

    // Code
import { NgZone } from '@angular/core';
import { interval } from 'rxjs';

constructor(private ngZone: NgZone) {}

this.ngZone.runOutsideAngular(() => {
    interval(10000).subscribe(() => {
        this.ngZone.run(() => {
            this.myFunction();
        });
    });
});

    Description: Use ngZone.runOutsideAngular in combination with RxJS interval to call the function every 10 seconds.

  9. "Angular ngIf with setTimeout for calling a function every 10 seconds"

    // Code
myFunction() {
    // Function implementation
}

ngAfterViewInit() {
    this.callFunctionEvery(10000);
}

callFunctionEvery(milliseconds: number) {
    setTimeout(() => {
        this.myFunction();
        this.callFunctionEvery(milliseconds);
    }, milliseconds);
}

    Description: Use setTimeout within a recursive function and conditionally call the specified function every 10 seconds.

  10. "Angular custom directive with setInterval for calling a function every 10 seconds"

    // Code
import { Directive, OnInit } from '@angular/core';

@Directive({
    selector: '[appRepeatFunction]',
})
export class RepeatFunctionDirective implements OnInit {
    ngOnInit() {
        setInterval(() => {
            this.myFunction();
        }, 10000);
    }

    myFunction() {
        // Function implementation
    }
}

    Description: Create a custom directive with setInterval to call the function every 10 seconds.
