How to create dynamic route in Angular
Dynamic routing in Angular empowers developers to handle varying data and navigate users to specific content or components based on dynamic parameters. Leveraging route parameters enables the creation of flexible and adaptable routes within an Angular application. Let’s explore the process of creating dynamic routes in Angular for versatile navigation.
Setting Up Dynamic Routes
1. Route Configuration
Define dynamic routes in the Angular AppRoutingModule
by specifying route parameters using the colon (:
) syntax:
import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { DynamicComponent } from './dynamic/dynamic.component';
const routes: Routes = [
{ path: 'dynamic/:id', component: DynamicComponent },
// Define additional dynamic routes as needed
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }
2. Accessing Route Parameters
In the dynamic component (DynamicComponent
in this example), access route parameters using Angular’s ActivatedRoute
:
import { Component, OnInit } from '@angular/core';
import { ActivatedRoute } from '@angular/router';
@Component({
selector: 'app-dynamic',
templateUrl: './dynamic.component.html',
styleUrls: ['./dynamic.component.css']
})
export class DynamicComponent implements OnInit {
dynamicId: string;
constructor(private route: ActivatedRoute) { }
ngOnInit(): void {
this.route.params.subscribe(params => {
this.dynamicId = params['id'];
// Use the dynamicId parameter in component logic
});
}
}
3. Navigating to Dynamic Routes
Navigate to dynamic routes by passing dynamic parameters when using the Angular router’s navigate()
method:
import { Component } from '@angular/core';
import { Router } from '@angular/router';
@Component({
selector: 'app-any-component',
templateUrl: './any-component.component.html',
styleUrls: ['./any-component.component.css']
})
export class AnyComponent {
constructor(private router: Router) { }
goToDynamicRoute(id: string) {
this.router.navigate(['/dynamic', id]);
}
}
4. Displaying Dynamic Content
In the HTML template of the dynamic component, utilize the received route parameters:
<p>Dynamic ID: {{ dynamicId }}</p>
<!-- Display dynamic content based on the received ID -->
Conclusion
Creating dynamic routes in Angular involves configuring routes with route parameters, accessing parameters using ActivatedRoute
, navigating to dynamic routes with dynamic parameters, and displaying content based on the received parameters. This functionality allows for versatile navigation and content presentation within Angular applications.
