Mastering mat-paginator: A Step-by-Step Guide on How to Synchronize Page Sizes

<mat-paginator
  [pageSize]="paginator.pageSize"
  (pageSizeChange)="paginator.setPageSize($event)>
  <mat-paginator>

Step 4: Synchronize Across Multiple Components

To synchronize page sizes across multiple components, inject the `PaginatorService` into each component and update the mat-paginator template accordingly:

import { Component } from '@angular/core';
import { MatPaginator } from '@angular/material/paginator';
import { PaginatorService } from './paginator.service';

@Component({
  selector: 'app-another-example',
  template: `
    <mat-paginator [pageSize]="paginator.pageSize" (pageSizeChange)="paginator.setPageSize($event)></mat-paginator>
  `
})
export class AnotherExampleComponent {
  constructor(private paginator: PaginatorService) { }
}

Advanced Synchronization Techniques

In some scenarios, you might need to synchronize page sizes across different routes or even across multiple Angular applications. Let’s explore some advanced techniques to achieve this:

Local Storage Synchronization

Use local storage to store the current page size and retrieve it across different routes or applications:

import { Injectable } from '@angular/core';

@Injectable({
  providedIn: 'root'
})
export class PaginatorService {
  private pageSize: number;

  constructor() {
    this.pageSize = parseInt(localStorage.getItem('pageSize'), 10) || 10;
  }

  getPageSize(): number {
    return this.pageSize;
  }

  setPageSize(size: number): void {
    this.pageSize = size;
    localStorage.setItem('pageSize', size.toString());
  }
}

Cookie-Based Synchronization

Use cookies to store the current page size and retrieve it across different routes or applications:

import { Injectable } from '@angular/core';
import { Cookie } from 'ng2-cookies';

@Injectable({
  providedIn: 'root'
})
export class PaginatorService {
  private pageSize: number;

  constructor() {
    this.pageSize = parseInt(Cookie.get('pageSize'), 10) || 10;
  }

  getPageSize(): number {
    return this.pageSize;
  }

  setPageSize(size: number): void {
    this.pageSize = size;
    Cookie.set('pageSize', size.toString());
  }
}

Best Practices and Caveats

When synchronizing page sizes, keep the following best practices and caveats in mind:

• Avoid over-reliance on shared services: While shared services can be powerful, they can also lead to tight coupling between components. Use them judiciously.
• Handle storage limitations: When using local storage or cookies, be mindful of storage limitations and ensure that you’re not exceeding them.
• Consider user preferences: Allow users to set their preferred page size and store it accordingly.

Conclusion

In this comprehensive guide, we’ve explored the world of synchronized page sizes in mat-paginator. By following the steps outlined above, you can ensure a seamless user experience across multiple mat-paginator instances. Remember to keep best practices and caveats in mind when implementing synchronization techniques.
