Material Theme Loader in Angular

This repo is based on a PoC.

How to use

1. Define a default theme in the AppModule

   @NgModule({
     declarations: [AppComponent],
     imports: [
       BrowserModule,
       ThemeLoaderModule.forRoot({
         isDefault: true,
         themeName: 'light-theme',
       }),
       AppRoutingModule,
     ],
     bootstrap: [AppComponent],
   })
   export class AppModule {}

2. Define the theme name each routed module to use

   const routes: Routes = [
     {
       path: 'admin',
       loadChildren: () =>
         import('./admin/admin.module').then((m) => m.AdminModule),
       data: {
         themeName: 'dark-theme',
       },
       canActivate: [ThemeLoader],
       canDeactivate: [ThemeUnloader],
     },
     {
       path: 'dashboard',
       loadChildren: () =>
         import('./dashboard/dashboard.module').then((m) => m.DashboardModule),
       data: {
         themeName: 'light-theme',
       },
       canActivate: [ThemeLoader],
       canDeactivate: [ThemeUnloader],
     },
   ];
   
   @NgModule({
     imports: [RouterModule.forRoot(routes)],
     exports: [RouterModule],
   })
   export class AppRoutingModule {}
