Share data between angular components using service
Today I am going to show you the data sharing between angular components using services. As I have already shared demo on data sharing using input decorator and data sharing using output decorator. So if you want you can navigate to these sections to see the demo.
In the demo, I will take an example of cart system in any e-commerce site. In any e-commerce site there is a cart which user manipulates as per his preference to buy the items from the site. And if you see the value in cart show on every navigated page same, Means data is sharing there thought the multiple components.
Let’s Get Started.
Step 1: Create Angular App and Cart Service
create an Angular app with Angular CLI. and create a service named CartService and put below code inside that file:
import { Injectable } from '@angular/core';
@Injectable()
export class CartService {
constructor() { }
public count = 0;
addToCart() {
this.count = this.count+1;
return this.count;
}
clearCart() {
return this.count = 0;
}
getCart(){
return this.count;
}
}
In the above service file, have created a public variable named count and 3 different methods to update the variable.
Step 2: Create component for product listing
open ts file of the product component and put below code
import { Component, OnDestroy,OnInit } from '@angular/core';
import { CartService } from '../cart.service';
@Component({
selector: 'app-home',
templateUrl: './product.component.html'
})
export class ProductComponent implements OnInit {
cart: any;
public fileUrl;
constructor(private cartService: CartService) {}
ngOnInit(){
this.getCart();
}
getCart(): void {
this.cart = this.cartService.getCart();
}
addToCart(): void {
this.cart = this.cartService.addToCart();
}
emptyCart(): void {
// clear message
this.cartService.clearCart();
}
}
In the above file, we have imported service and have methods to update the value in cart service.
now update product.component.html
<div class="text-center">
<a routerLink="">Product</a> |
<a routerLink="cart-detail">cart detail</a>
<p>Cart count</p><span *ngIf="cart && cart.text">{{cart.text}}</span>
<!-- main app container -->
<h2>This is produst listing page...</h2>
<p>Cart count:{{cart}}</p>
<button (click)="addToCart()" class="btn btn-primary">Add Product in cart</button>
<button (click)="emptyCart()" class="btn btn-secondary">Empty Cart</button>
</div>
In the above file we have shown the cart value and below we have two button to increase the cart value and make it empty.
Step 3: Create a Cart detail component
After creating a new component from the command line open the cart-detail.component.ts and put the below code:
import { Component, OnDestroy,OnInit } from '@angular/core';
import { CartService } from '../cart.service';
@Component({
selector: 'app-home',
templateUrl: './product.component.html'
})
export class ProductComponent implements OnInit {
cart: any;
public fileUrl;
constructor(private cartService: CartService) {}
ngOnInit(){
this.getCart();
}
getCart(): void {
this.cart = this.cartService.getCart();
}
addToCart(): void {
this.cart = this.cartService.addToCart();
}
emptyCart(): void {
this.cartService.clearCart();
}
}
Same like product ts file we have called service methods from cart detail component also. Now update HTML file of cart detail component.
<div class="text-center">
<a routerLink="">Product</a> |
<a routerLink="cart-detail">cart detail</a>
<p>Cart count</p><span *ngIf="cart && cart.text">{{cart.text}}</span>
<!-- main app container -->
<h2>This is produst listing page...</h2>
<p>Cart count:{{cart}}</p>
<button (click)="addToCart()" class="btn btn-primary">Add Product in cart</button>
<button (click)="emptyCart()" class="btn btn-secondary">Empty Cart</button>
</div>
Now our component and service part is done.
Step 4: Update routing file
Make sure you have below routings in route file:
const routes: Routes = [{
path: '', component: ProductComponent
},
{
path:'cart-detail',component:CartDetailComponent
}
];
Also update app.component.html file inside app folder and remove all other code except .
Step 5: Run the app
After completing all the needed task now run the app with NPM start and check the app over the browser. You would see like below:
Conclusion
In this demo, we learn about the data sharing between angular components using services. You can find other demos at Angular sample projects
That’s all for now. Thank you for reading and I hope this post will be very helpful for data sharing between angular components using service.

Pdf2gerb: Perl Script Converts PDF Files to Gerber format
pdf2gerb
Perl script converts PDF files to Gerber format
Pdf2Gerb generates Gerber 274X photoplotting and Excellon drill files from PDFs of a PCB. Up to three PDFs are used: the top copper layer, the bottom copper layer (for 2-sided PCBs), and an optional silk screen layer. The PDFs can be created directly from any PDF drawing software, or a PDF print driver can be used to capture the Print output if the drawing software does not directly support output to PDF.
The general workflow is as follows:
- Design the PCB using your favorite CAD or drawing software.
- Print the top and bottom copper and top silk screen layers to a PDF file.
- Run Pdf2Gerb on the PDFs to create Gerber and Excellon files.
- Use a Gerber viewer to double-check the output against the original PCB design.
- Make adjustments as needed.
- Submit the files to a PCB manufacturer.
Please note that Pdf2Gerb does NOT perform DRC (Design Rule Checks), as these will vary according to individual PCB manufacturer conventions and capabilities. Also note that Pdf2Gerb is not perfect, so the output files must always be checked before submitting them. As of version 1.6, Pdf2Gerb supports most PCB elements, such as round and square pads, round holes, traces, SMD pads, ground planes, no-fill areas, and panelization. However, because it interprets the graphical output of a Print function, there are limitations in what it can recognize (or there may be bugs).
See docs/Pdf2Gerb.pdf for install/setup, config, usage, and other info.

#Pdf2Gerb config settings:
#Put this file in same folder/directory as pdf2gerb.pl itself (global settings),
#or copy to another folder/directory with PDFs if you want PCB-specific settings.
#There is only one user of this file, so we don't need a custom package or namespace.
#NOTE: all constants defined in here will be added to main namespace.

Create Pagination Using jQuery
In this article, we will see how to create pagination using jquery. We will create jquery pagination using multiple ways. You can create pagination using different ways like creating pagination using simple HTML, you can create pagination in laravel using paginate() method. Also, create pagination laravel livewire, pagination using bootstrap.
We will create simple jquery pagination. Also, create pagination using jquery without a plugin and create jquery pagination with next and previous buttons
So, let's see dynamic pagination in jquery and bootstrap pagination in jquery
Example:
In this example, we will create pagination using jquery without using a plugin. Also, you can customize the pagination.

Your Data Architecture: Simple Best Practices for Your Data Strategy
If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.
If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.
In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.
