Effortless Data Management with Server-Side Pagination in Angular

Unlocking the Power of Server-Side Pagination

When dealing with large datasets, displaying all the data at once can be overwhelming. This is where server-side pagination comes in – a technique that allows you to control the amount of data requested from the server, making it easier to manage and display.

What is Server-Side Pagination?

Server-side pagination is a method of fetching a subset of data from the server, rather than retrieving the entire dataset at once. This approach is particularly useful when working with large datasets, as it enables you to break down the data into manageable chunks.

Introducing ngx-pagination

ngx-pagination is an Angular package manager that simplifies the process of implementing server-side pagination. This powerful tool allows you to view data in pages, making it easier to work with large datasets.

Getting Started with ngx-pagination

To get started with ngx-pagination, you’ll need to install the package using the following command:

npm install ngx-pagination

Once installed, import the ngx-pagination module into your app.module.ts file and add it to the imports section.

import { NgxPaginationModule } from 'ngx-pagination';

@NgModule({
  imports: [NgxPaginationModule],
  //...
})
export class AppModule {}

Feching Data with the Fetch API

In this example, we’ll be using the Fetch API to retrieve data from a faux airline passenger database. We’ll create a function called getAllPassengerData() to handle the API request.

function getAllPassengerData(): Promise {
  return fetch('https://example.com/passenger-data')
   .then(response => response.json())
   .catch(error => console.error(error));
}

Implementing Server-Side Pagination

To implement server-side pagination, we’ll need to pass the page count to the ngx-pagination component. We’ll declare a variable called currentPage and assign it a value of 1, which will display the current page we’re on.

currentPage = 1;

Configuring ngx-pagination

ngx-pagination requires two essential attributes: ItemsPerPage and CurrentPage. ItemsPerPage determines the number of items to be displayed on each page, while CurrentPage specifies the current page number.

<ngx-pagination
  [itemsPerPage]="10"
  [(currentPage)]="currentPage"
></ngx-pagination>

Putting it all Together

With ngx-pagination configured, we can now display our passenger data in a more manageable format. We’ll create a pagination component and pass in the required attributes.

<pagination
  [data]="passengerData"
  [itemsPerPage]="10"
  [(currentPage)]="currentPage"
></pagination>

The Result

After implementing server-side pagination with ngx-pagination, we’ll have a more organized and user-friendly interface for displaying our passenger data.

• Easy data management: With server-side pagination, we can control the amount of data requested from the server, making it easier to manage and display.
• Improved user experience: By breaking down the data into manageable chunks, we can provide a more user-friendly interface for our users.
