Managing refresh events in Angular with F5 Key

Recently, I encountered an issue with my Angular project. During development (using ng s), everything functions normally and upon pressing F5, the page reloads correctly and works fine.

However, when I build and deploy the project to a remote server, all seems well until I press F5, resulting in a 404 error - page not found. What could be causing this issue?

This is my router module configuration:

const routes: Routes = [
  // main routing paths
  { path: "login", component: LoginComponent },
  { path: "registration", component: RegisterComponent },
  { path: "resetPassword", component: ResetPasswordComponent },
  { path: "resetPasswordNew", component: InsertNewPasswordComponent },

  {path: "system",
  component: MainComponentComponent, 
  canActivate: [AuthGuard], // Auth guard returns true or false based on whether a token is loaded
  children: [ 
    { path: 'dashboard', component: DashboardComponent, canActivate: [RoleGuardService]},  // RoleGuardService checks if user is student or teacher
    { path: 'baterie' , component: BaterieComponent},
    { path: 'settings' , component: SettingsComponent,
    children: [
      {path: 'info' , component: InfoComponent, canActivate: [RoleGuardService]}
    ]
    },
    { path: '', redirectTo: 'dashboard', pathMatch: 'full', },
  ]
  },

  { path: '', redirectTo: 'login', pathMatch: 'full', },
];

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

Your insights would be greatly appreciated!

Take a look at the Angular Deployment documentation for valuable insights.

For routed applications, it is crucial to have a fallback to index.html

Angular applications are well-suited for serving with a basic static HTML server. There's no need for a server-side engine to generate application pages dynamically as Angular handles that on the client-side.

If your app utilizes the Angular router, ensure that the server is set up to serve the application's main page (index.html) when requested for a missing file.

A routed app should be able to handle "deep links", which are URLs specifying a path to a component within the app. For example, http://example.com/heroes/42 directs you to the hero detail page showing the hero with ID 42.

When a user accesses such a URL while already in the app, the Angular router manages the routing seamlessly. However, external actions like clicking an email link or manually entering the URL in the browser can bypass the router and result in a direct request to the server.

A typical static server responds with index.html for requests to http://example.com/, but may return a 404 error for URLs like http://example.com/heroes/42 unless configured otherwise.
