Error 404 when implementing routing in Angular 2 with Auth0

In my Angular 2 application, I am utilizing Auth0 authentication.

While everything works fine on localhost, I encounter issues when running the application on the server (my domain).

Based on what I know, my problem seems to be with the routes.



Issue:

I can successfully log in using Auth0 in my Angular app (both on localhost and on the server - including logout). Post login, the application redirects to my Control Page without any issues, and within the application, I have menus, pages with their respective routes, etc.

Everything functions correctly on localhost, BUT after logging in on the server, I am unable to navigate between the pages in my app. Everything results in a 404 page, even upon refreshing the page.

In addition to this, I am also incorporating JQuery and Materialize CSS. Upon reloading, JQuery fails to load initially but eventually loads after the refresh, making the effects work.



Code:

app.routing.ts:

import { ModuleWithProviders } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { AuthGuard } from './auth/auth.guard';

import { HomeComponent } from './components/home/home.component';
import { PainelComponent } from './components/painel/painel.component';
import { ReunioesComponent } from './components/reunioes/reunioes.component';
import { AssociadosComponent } from './components/associados/associados.component';
import { CalendarioComponent } from './components/calendario/calendario.component';
import { TesourariaComponent } from './components/tesouraria/tesouraria.component';
import { DocumentosComponent } from './components/documentos/documentos.component';

const appRoutes: Routes = [
    {
        path: '',
        component: HomeComponent
    },
    {
        path: 'painel',
        component: PainelComponent,
        canActivate: [AuthGuard]
    },
    {
        path: 'associados',
        component: AssociadosComponent,
        canActivate: [AuthGuard]
    },
    {
        path: 'calendario',
        component: CalendarioComponent,
        canActivate: [AuthGuard]
    },
    {
        path: 'reunioes',
        component: ReunioesComponent,
        canActivate: [AuthGuard]
    },
    {
        path: 'tesouraria',
        component: TesourariaComponent,
        canActivate: [AuthGuard]
    },
    {
        path: 'documentos',
        component: DocumentosComponent,
        canActivate: [AuthGuard]
    }
];

export const appRoutingProviders: any[] = [];
export const routing: ModuleWithProviders = RouterModule.forRoot(appRoutes, {useHash: false})


auth.service.ts:

import { Injectable } from '@angular/core';
import { Router } from '@angular/router';
import { tokenNotExpired } from 'angular2-jwt';

declare var Auth0Lock: any;

@Injectable()
export class Auth {
    lock = new Auth0Lock('SECRET', 'SECRET.auth0.com', {});

    constructor(private router: Router) {
        this.lock.on("authenticated", (authResult) => {
            this.lock.getProfile(authResult.idToken, (err, profile) => {
                if(err)
                    throw new Error(err)

                localStorage.setItem('profile', JSON.stringify(profile));
                localStorage.setItem('id_token', authResult.idToken);

                this.router.navigate(['/painel'])
            })
        });
    }

    public login() {
        this.lock.show()
    }

    public authenticated() {
        return tokenNotExpired()
    }

    public logout() {
        localStorage.removeItem('id_token');
        localStorage.removeItem('profile')
    }
}

Answer №1

When setting up Auth0 in my ng2 application, I encountered a similar issue as yours regarding routing. The solution lies in how you configure your routing mechanism. To resolve this problem, you will need to implement HashLocationStrategy. Simply include the following snippet in the providers array within your app.module.ts:


 {
   provide: LocationStrategy,
   useClass: HashLocationStrategy
 },

After making this adjustment, refer to the guide linked below for detailed instructions on correctly incorporating hash routing with Auth0 (consider workaround #2 if using a more recent version of ng2):
