Guys is the main part of loader spinner. We can change its bdColor(background color), size(small, medium, large), color(text color), fullScreen(true, false). To show inside particular div we have to make that div position static as well.

<ngx-spinner bdColor = "rgba(0, 0, 0, 0.8)" size = "small" color = "#fff" type = "square-jelly-box" [fullScreen] = "false">
        <p style="color: white" > Loading... </p>
</ngx-spinner>

Angular 13 came and Bootstrap 5 also and if you are new then you must check below two links:

  1. Angular13 Tutorials
  2. Angular12 Free Templates
  3. Bootstrap 5

Friends now I proceed onwards and here is the working code snippet and please use carefully this to avoid the mistakes:

1. Firstly friends we need fresh angular 13 setup and for this we need to run below commands but if you already have angular 13 setup then you can avoid below commands. Secondly we should also have latest node version installed on our system:

npm install -g @angular/cli 

ng new angularboot5 //Create new Angular Project

cd angularboot5 // Go inside the Angular Project Folder

2. Now friends, here we need to run below commands into our project terminal to install bootstrap 5 modules(for good layout and we can skip this as well) and ngx-spinner modules into our angular application:

npm install bootstrap

npm i @popperjs/core

npm install ngx-spinner --save 

3. Now friends we just need to add below code into src/app/app.component.html file to get final out on the web browser:

<div class="container">
    <!-- Stack the columns on mobile by making one full-width and the other half-width -->
    <div class="row">
      <div class="col-md-8 bg-primary position-relative">
        
        Lorem Ipsum is simply dummy text of the printing and typesetting industry. 
          Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown 
          printer took a galley of type and scrambled it to make a type specimen book. It has survived not 
          only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. 
          It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, 
          and more recently with desktop 
          publishing software like Aldus PageMaker including versions of Lorem Ipsum.</div>
      <div class="col-6 col-md-4 bg-secondary position-relative">
<ngx-spinner bdColor = "rgba(0, 0, 0, 0.8)" size = "small" color = "#fff" type = "square-jelly-box" [fullScreen] = "false">
        <p style="color: white" > Loading... </p></ngx-spinner>

    </div>
 </div>

4. Now friends we just need to add below code into angular.json file:

"styles": [
              ...
              "node_modules/bootstrap/dist/css/bootstrap.min.css"
          ],
"scripts": [
              ...
               "node_modules/bootstrap/dist/js/bootstrap.min.js"
           ]

5. Now friends we just need to add below code into src/app/app.component.ts file:

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

import { NgxSpinnerService } from "ngx-spinner";
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private spinner: NgxSpinnerService) { }
  
 ngOnInit(){
   

    /** spinner starts on init */
    this.spinner.show();

    setTimeout(() => {
      /** spinner ends after 5 seconds */
      this.spinner.hide();
    }, 5000);
  
  }

}

6. Now friends we just need to add below code into src/app/app.module.ts file:

...
// Import library module
import { NgxSpinnerModule } from "ngx-spinner";
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
 

@NgModule({
  ...
  imports: [
  ...
    NgxSpinnerModule,
    BrowserAnimationsModule
  ],
  schemas: [CUSTOM_ELEMENTS_SCHEMA],
 ...

Friends in the end must run ng serve command into your terminal to run the angular 13 project.

Now we are done friends. If you have any kind of query, suggestion and new requirement then feel free to comment below.

Note: Friends, In this post, I just tell the basic setup and things, you can change the code according to your requirements.

I will appreciate that if you will tell your views for this post. Nothing matters if your views will be good or bad because with your views, I will make my next posts more good and helpful.

Jassa
