RouterModule error - Property 'forRoot' is undefined

I've been working on setting up routing in Angular and encountered an issue with the error message:

Cannot read property 'forRoot' of undefined

Here is my app.routes.ts file:

import { RouterModule, Routes } from '@angular/router';
import { LoginComponent } from '../../components/login/login.component';
import { SignupComponent } from '../../components/signup/signup.component';
import { ResourcesComponent } from '../../components/resources/resources.component';
import { MyApp } from './app.component';
const routes: Routes=[
    {path:'',component:MyApp},
    {path:'login',component:LoginComponent},
    {path:'signup', component:SignupComponent},
    {path:'resources',component:ResourcesComponent},
];
export const routing=RouterModule.forRoot(routes);

In my app.module.ts file:

import { NgModule, ErrorHandler } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { MyApp } from './app.component';
import { LoginComponent } from '../../components/login/login.component';
import { SignupComponent } from '../../components/signup/signup.component';
import { ResourcesComponent } from '../../components/resources/resources.component'; 
import { NavbarComponent } from '../../components/navbar/navbar.component';
import { RouterModule, Routes } from '@angular/router';
import { routes } from './app.routes';

@NgModule({
    declarations:[
        MyApp,
        LoginComponent,
        SignupComponent,
        ResourcesComponent,
        NavbarComponent
    ],
    entryComponents: [MyApp],
    imports:[BrowserModule,RouterModule.forRoot(routes)],
    bootstrap: [MyApp]
})
export class AppModule {}

Unfortunately, I'm receiving errors related to RouterModule and routes: @angular/router/index has no exported member 'RouterModule' and 'Routes'

Answer №1

It appears that you may be using a deprecated way to route in your Angular application without specifying the version you are using. To update your routing method, you can follow the example provided by @Maciej Soabala above. Additionally, if you prefer to export the routes as a separate module, you can refer to the following link:

https://angular.io/guide/router#refactor-the-routing-configuration-into-a-routing-module

This will adjust your code structure to resemble the following:

import { RouterModule, Routes } from '@angular/router';
import { LoginComponent } from '../../components/login/login.component';
import { SignupComponent } from '../../components/signup/signup.component';
import { ResourcesComponent } from '../../components/resources/resources.component';
import { MyApp } from './app.component';

const routes: Routes=[
    {path:'',component:MyApp},
    {path:'login',component:LoginComponent},
    {path:'signup', component:SignupComponent},
    {path:'resources',component:ResourcesComponent},
];

@NgModule({
  imports: [
    RouterModule.forRoot(routes)
  ],
  exports: [
    RouterModule
  ]
})

export class routing{}

Once configured, you can easily import the 'routing' module into other modules within your application and make use of it accordingly.

Answer №2

Upon reviewing the information provided here: https://angular.io/api/router/RouterModule

It is recommended to utilize RouterModule within the NgModule. Ensure that your file exports routes instead of routing:

import { Routes } from '@angular/router';
import { LoginComponent } from '../../components/login/login.component';
import { SignupComponent } from '../../components/signup/signup.component';
import { ResourcesComponent } from '../../components/resources/resources.component';
import { MyApp } from './app.component';
export const routes: Routes=[
    {path:'',component:MyApp},
    {path:'login',component:LoginComponent},
    {path:'signup', component:SignupComponent},
    {path:'resources',component:ResourcesComponent},
];

Next, in the module file:

import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';
import { routes } from './app.routes';

@NgModule({
  imports: [RouterModule.forRoot(routes)]
})
class MyNgModule {}

Answer №3

For those utilizing SystemJS version 0.20 or above for module loading, here's the recommended configuration:

System.config({
    meta: {
        "./*": {
        "esModule": true
        }
    }
<additional configurations>
});
