I am developing an Angular application, and the version did not work as I wish. I’ve got multiple modules in this app and I used the lazy routing. But when I tried to navigate to sub module’s route, but it failed with ERROR RuntimeError: NG04002: Cannot match any routes. URL Segment: ‘pageList’. I wondered why. Here is my code.
I have got App module, Console module, and Login module. Here is some key codes:
- app.html
<router-outlet></router-outlet>
- app.routes.ts
import { Routes } from '@angular/router';
import { Login } from './login/login/login';
import { Console } from './console/console/console';
export const routes: Routes = [
{ path: '', pathMatch: 'full', redirectTo: '/login' },
{ path: 'login', component: Login, loadChildren: () => import('./login/login-module').then(m => m.LoginModule) },
{ path: 'console', component: Console, loadChildren: () => import('./console/console-module').then(m => m.ConsoleModule) },
];
- app.config.ts
import { ApplicationConfig, provideBrowserGlobalErrorListeners, provideZonelessChangeDetection } from '@angular/core';
import { PreloadAllModules, provideRouter, RouteReuseStrategy, withPreloading } from '@angular/router';
import { routes } from './app.routes';
import { provideClientHydration, withEventReplay } from '@angular/platform-browser';
import { provideHttpClient } from '@angular/common/http';
import { SimpleReuseStrategy } from './console/SimpleReuseStrategy';
export const appConfig: ApplicationConfig = {
providers: [
provideHttpClient(),
provideBrowserGlobalErrorListeners(),
provideZonelessChangeDetection(),
provideRouter(routes,withPreloading(PreloadAllModules)),
provideClientHydration(withEventReplay()),
{
provide: RouteReuseStrategy, useClass: SimpleReuseStrategy
}
]
};
