Angular Router Store

Bindings to connect Angular router to Elf store.

To get started, install the @ngneat/elf-ng-router-store package and add to the AppModule the Elf’s devtools modules:

import { ElfNgRouterStoreModule } from '@ngneat/elf-ng-router-store';

@NgModule({
imports: [
  ElfNgRouterStoreModule
})
export class AppModule {
}

With this setup, you'll get two things:

1. You'll see the Router actions in Redux devtools.
2. A unique set of selectors to query the router state:

selectParams

import { RouterRepository } from '@ngneat/elf-ng-router-store';

export class UsersRepository {
   constructor(private routerRepository: RouterRepository) {
     routerRepository.selectParams().subscribe();
     routerRepository.selectParams('id').subscribe();
     routerRepository.selectParams(['id', 'type']).subscribe();
   }
}

getParams

import { RouterRepository } from '@ngneat/elf-ng-router-store';

export class UsersRepository {
   constructor(private routerRepository: RouterRepository) {
     const params = routerRepository.getParams()
   }
}

selectQueryParams

import { RouterRepository } from '@ngneat/elf-ng-router-store';

export class UsersRepository {
   constructor(private routerRepository: RouterRepository) {
     routerRepository.selectQueryParams().subscribe();
     routerRepository.selectQueryParams('redirectTarget').subscribe();
     routerRepository.selectQueryParams(['redirectTarget', 'type']).subscribe();
   }
}

getQueryParams

import { RouterRepository } from '@ngneat/elf-ng-router-store';

export class UsersRepository {
   constructor(private routerRepository: RouterRepository) {
     const redirectTarget = routerRepository.getQueryParams().redirectTarget
   }
}

selectFragment

import { RouterRepository } from '@ngneat/elf-ng-router-store';

export class UsersRepository {
   constructor(private routerRepository: RouterRepository) {
     routerRepository.selectFragment().subscribe();
   }
}

getFragment

import { RouterRepository } from '@ngneat/elf-ng-router-store';

export class UsersRepository {
   constructor(private routerRepository: RouterRepository) {
     const fragment = routerRepository.getFragment()
   }
}

selectData

import { RouterRepository } from '@ngneat/elf-ng-router-store';

export class UsersRepository {
   constructor(private routerRepository: RouterRepository) {
     routerRepository.selectData().subscribe();
     routerRepository.selectData('id').subscribe();
     routerRepository.selectData(['id', 'type']).subscribe();
   }
}

getData

import { RouterRepository } from '@ngneat/elf-ng-router-store';

export class UsersRepository {
   constructor(private routerRepository: RouterRepository) {
     const data = routerRepository.getData()
   }
}

selectNavigationExtras

import { RouterRepository } from '@ngneat/elf-ng-router-store';

export class UsersRepository {
   constructor(private routerRepository: RouterRepository) {
     routerRepository.selectNavigationExtras().subscribe();
     routerRepository.selectNavigationExtras('id').subscribe();
     routerRepository.selectNavigationExtras(['id', 'type']).subscribe();
   }
}

getNavigationExtras

import { RouterRepository } from '@ngneat/elf-ng-router-store';

export class UsersRepository {
   constructor(private routerRepository: RouterRepository) {
     const extras = routerRepository.getNavigationExtras()
   }
}

selectNavigationCancel

import { RouterRepository } from '@ngneat/elf-ng-router-store';

export class UsersRepository {
   constructor(private routerRepository: RouterRepository) {
     routerRepository.selectNavigationCancel().subscribe();
   }
}

selectNavigationError

import { RouterRepository } from '@ngneat/elf-ng-router-store';

export class UsersRepository {
   constructor(private routerRepository: RouterRepository) {
     routerRepository.selectNavigationError().subscribe();
   }
}

Use case

For example, we can create a query that maps an id from the URL to an entity in the store:

export class ArticlesRepository {
  selectArticle$ = this.routerRepository.selectParams('id').pipe(
     switchMap(id => this.selectEntity(id))
  );

  constructor(private routerRepository: RouterRepository) {}
}

And use it in the component:

@Component()
export class ArticleComponent {
  article$ = this.articlesRepository.selectArticle$;

  constructor(private articlesRepository: ArticlesRepository) {}
}

Lazy Load Modules

To get the lazy modules routing params, add the following option to the RouterModule.forRoot method:

{
  imports: [
    RouterModule.forRoot(routes, {
      paramsInheritanceStrategy: 'always'
    })
  ]
}
