Hello to all, welcome again on therichpost.com. In this post, I will tell you, Angular 9 owl carousel with Node Js backend.

Post Working:

In this post, I am implementing Owl Carousel in Angular 9 and showing images in that slider with Node js backend.

Here is the working video from where you can get Owl Carousel In Angular 8, 9:

Here is the working code snippet and please follow carefully:

1. Very first, here are common basics steps to add angular 9 application on your machine:

$ npm install -g @angular/cli

$ ng new angularowlslider // Set Angular9 Application on your pc

cd angularowlslider // Go inside project folder

ng serve // Run project

http://localhost:4200/  //Check working Local server

 

2. Now run below command into your terminal to include owl carousel package into your angular 9 application:

npm i ngx-owl-carousel-o

 

3. Now, add below code into your angular.json file:

....
"styles": [
    "node_modules/ngx-owl-carousel-o/lib/styles/prebuilt-themes/owl.carousel.min.css",
    "node_modules/ngx-owl-carousel-o/lib/styles/prebuilt-themes/owl.theme.default.min.css",
    "src/styles.css"
  ],
....

 

4. Now add below code into your app.module.ts file:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { CarouselModule } from 'ngx-owl-carousel-o';
import { AppComponent } from './app.component';
import { HttpClientModule } from '@angular/common/http';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    CarouselModule,
    HttpClientModule,
    BrowserAnimationsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

 

5. Now add below code into your app.component.ts file:

In this, I have also made API call to get data from node jsbackend:

import { Component } from '@angular/core';
import { HttpClient} from '@angular/common/http';
import { OwlOptions } from 'ngx-owl-carousel-o';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  images:any;
  constructor(private http: HttpClient){
    this.http.get('http://localhost/8080/api/data').subscribe(data => {
        this.images = data;
        }, error => console.error(error));
  }
 
  
  customOptions: OwlOptions  = {
    loop: true,
    mouseDrag: false,
    touchDrag: false,
    pullDrag: false,
    dots: false,
    navSpeed: 700,
    navText: ['', ''],
    responsive: {
      0: {
        items: 1
      },
      400: {
        items: 2
      },
      740: {
        items: 3
      },
      940: {
        items: 4
      }
    },
    nav: true
  }
}

 

6. Finally add, below code into your app.component.html file:

In this, I am getting images data with *ngfor looping:

<div style="text-align:center">
  <h1>
    Welcome to {{ title }}!
  </h1>
  <div>Some tags before</div>
  <owl-carousel-o [options]="customOptions">
    <ng-container *ngFor="let image of this.images;">
      <ng-template carouselSlide><img src="{{image.image}}"></ng-template> 
    </ng-container> 
  </owl-carousel-o>

  <div>Some tags after</div>
</div>

 

7. Here I have made custom API in nodejs file from where I am showing images in Owl Carousel Angular 9:

const express = require('express');
const app = express();
const cors = require('cors');
app.use(cors());
//I create api route with custom data
app.route('/api/data').get((req, res) => {
res.send({
events: [{ image: 'https://jaxenter.de/wp-content/uploads/2016/01/angularjs_2_0-log-500x375.jpg' },{ image: 'https://jaxenter.de/wp-content/uploads/2016/01/angularjs_2_0-log-500x375.jpg' },{ image: 'https://jaxenter.de/wp-content/uploads/2016/01/angularjs_2_0-log-500x375.jpg' } ]
});
});
app.listen(8080, () => {
console.log('Server started!');
});

 

8. After execute node file with node node.js command, you will see below json data into your browser:

This is it and if you have any query related to this post, then please let me know or comment below.
