Angular 16 provideRouter Example: Use Standalone Components with Angular 16 Router

In this example we will learn about Angular 16 routing using provideRouter and standalone components.

We finally witnessed the arrival of standalone components in Angular v15.

The addition of @NgModule as optional transforms how we design routes and routing definitions.

So how can we establish routing in Angular 16 with standalone components?

We must first bootstrap the Angular application. Let's begin with a simple App component that is bootstrapped using bootstrapApplication:

import { Component } from '@angular/core';
import { bootstrapApplication } from '@angular/platform-browser';

@Component({
  selector: 'my-app',
  standalone: true,
  template: `
    Angular 16 provideRouter example
  `,
})
export class App {}

bootstrapApplication(App);

Previously, we had to call the RouterModule.forRoot() function and pass in our routing configurations.

So, how can we transition to the new standalone design while keeping our routing?

Suppose we have the following routes:

import { Route } from '@angular/router';
import { ProductsComponent } from '../products.component';
import { ProductComponent } from './product.component';

export const routes: Route[] = [
  {
    path: '',
    component: CustomersComponent,
  },
  {
    path: ':id',
    component: CustomerComponent,
  },
  {
    path: '**',
    redirectTo: '',
  },
];

These need to be added to a routes.ts file.

Using provideRouter to import routes

We must now import a new function provideRouter and feed it to the bootstrapApplication providers as follows:

import { Component } from '@angular/core';
import { provideRouter } from '@angular/router';
import { bootstrapApplication } from '@angular/platform-browser';

import { routes } from './routes';

@Component({
  selector: 'my-app',
  standalone: true,
  template: `
    Angular 16 provideRouter example
  `,
})
export class App {}

bootstrapApplication(App, {
  providers: [provideRouter(routes)],
});

That's OK for the time being, but we need a <router-outlet> to render our components!

Import RouterOutlet

We'll need to import the RouterOutlet directive and add it to the component imports metadata because we're utilizing standalone components:

import { Component } from '@angular/core';
import { provideRouter, RouterOutlet } from '@angular/router';
import { bootstrapApplication } from '@angular/platform-browser';

import { routes } from './routes';

@Component({
  selector: 'my-app',
  standalone: true,
  imports: [RouterOutlet],
  template: `
    <router-outlet></router-outlet>
  `,
})
export class App {}

bootstrapApplication(App, {
  providers: [provideRouter(routes)],
});
