Query String Helper Service

The Query String Helper Service is a utility service for handling query strings, hash parameters, and path parameters in Angular applications.

Overview

The Query String Helper Service provides methods to parse query strings, hash parameters, and path parameters from the current URL.

Installation

To use the Query String Helper Service in your Angular application, follow these steps:

1. Installation: There's no need to install any additional packages. The Query String Helper Service is included in the @angular/core module, which is a core dependency of Angular applications.

2. Usage: Import the `Injectable` decorator from `@angular/core` and create a service class to handle query strings, hash parameters, and path parameters.

Example Usage

Here's an example of how to use the Query String Helper Service in your Angular application:

1. Import the `Injectable` decorator from `@angular/core`:

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

2. Create a service class named `QueryStringHelperService` and decorate it with the `Injectable` decorator. Provide the service in the root injector by setting the `providedIn` property to `'root'`:

   @Injectable({
   providedIn: 'root'
   })
   export class QueryStringHelperService {
   // Methods and properties go here...
   }

3. Implement methods to parse query strings, hash parameters, and path parameters using the `parseParams` and `parseParamsFromPath` methods provided by the service.

4. Use the `QueryString`, `HashParams`, and `PathParams` properties to access the parsed parameters:

   import { QueryStringHelperService } from './query-string-helper.service';
   
   @Component({
   selector: 'app-your-component',
   templateUrl: './your-component.component.html',
   styleUrls: ['./your-component.component.css']
   })
   export class YourComponent implements OnInit {
   
   constructor(private queryStringHelper: QueryStringHelperService) { }
   
   ngOnInit(): void {
   const queryStringParams = this.queryStringHelper.QueryString;
   const hashParams = this.queryStringHelper.HashParams;
   const pathParams = this.queryStringHelper.PathParams;
   
       console.log('Query String Parameters:', queryStringParams);
       console.log('Hash Parameters:', hashParams);
       console.log('Path Parameters:', pathParams);
   }
   }
