How To Add Loader/Spinner on Http Call In Angular

Hello Friends, In this article, we will learn how to add an http-loader in the Angular application. Many developers need to auto-show loader when we call APIs or get remote data. here we have to find the solution when we get data remotely then auto hide-show loader.

First, we need to add the http-loader NPM packages. run the following command in the terminal.

npm install ng-http-loader

Now, Add HttpClientModule and NgHttpLoaderModule in the app module use the following code:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { HttpClientModule } from '@angular/common/http';
import { NgHttpLoaderModule } from 'ng-http-loader';

  declarations: [
  imports: [
  providers: [],
  bootstrap: [AppComponent]
export class AppModule { }


Now, simply add loader in your app.component.html:


You can customize the following parameters:

Spinner backdrop:- by default visible(true/false).
Background color:- the color of the spinner.
Debounce delay:- after how many milliseconds the spinner will be visible.
Extra duration:- how many extra milliseconds should the spinner be visible.
Minimum duration:- how many minimum milliseconds should the spinner be visible.
Spinner Type:- the type of spinner
– skChasingDots
– skCubeGrid
– skDoubleBounce
– skRotatingPlane
– skSpinnerPulse
– skThreeBounce
– skWanderingCubes
– skWave

Specify the spinner type this way, add the following code in app.component.ts:

import { Component } from '@angular/core'; 
import { Spinkit } from 'ng-http-loader';

    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css'],
export class AppComponent {
    public spinkit = Spinkit;

Update the loader in your app.component.html


Note: Performing HTTP requests with the HttpClientModule API is mandatory. Otherwise, the loader will not be fired at all.
