Keep your Angular2+ router state in Redux

@angular-redux/router

Bindings to connect @angular/router to @angular-redux/core

Setup

1. Use npm to install the bindings:

npm install @angular-redux/router --save

2. Use the routerReducer when providing Store:

import { combineReducers } from 'redux';
import { routerReducer } from '@angular-redux/router';

export default combineReducers<IAppState>({
  // your reducers..
  router: routerReducer
});

3. Add the bindings to your root module.

import { NgModule } from '@angular/core';
import { NgReduxModule, NgRedux } from '@angular-redux/core';
import { NgReduxRouterModule, NgReduxRouter } from '@angular-redux/router';
import { RouterModule } from '@angular/router';
import { routes } from './routes';

@NgModule({
  imports: [
    RouterModule.forRoot(routes),
    NgReduxModule,
    NgReduxRouterModule
    // ...your imports
  ],
  // Other stuff..
})
export class AppModule {
  constructor(
    ngRedux: NgRedux<IAppState>,
    ngReduxRouter: NgReduxRouter
  ) {
    ngRedux.configureStore(/* args */);
    ngReduxRouter.initialize(/* args */);
  }
}

What if I use Immutable.js with my Redux store?

When using a wrapper for your store's state, such as Immutable.js, you will need to change two things from the standard setup:

1. Provide your own reducer function that will receive actions of type UPDATE_LOCATION and return the payload merged into state.
2. Pass a selector to access the payload state and convert it to a JS object via the selectLocationFromState option on NgReduxRouter's initialize().

These two hooks will allow you to store the state that this library uses in whatever format or wrapper you would like.

What if I have a different way of supplying the current URL of the page?

Depending on your app's needs. It may need to supply the current URL of the page differently than directly through the router. This can be achieved by initializing the bindings with a second argument: urlState$. The urlState$ argument lets you give NgReduxRouter an Observable<string> of the current URL of the page. If this argument is not given to the bindings, it defaults to subscribing to the @angular/router's events, and getting the URL from there.
