A quick example of ngrx integrated with Ionic Framework 3.

Install packages as usual:

npm install

The packages that are new to this repo are:

npm i --save reselect ngrx-store-ionic-storage @ngrx/core @ngrx/effects @ngrx/store @ngrx/store-devtools

ionic cordova plugin add cordova-sqlite-storage --save

The default home page is set to the Settings page. Run as usual, change the example settings, and reload the browser - your changes will persist between refreshes.

ionic serve

For an introduction to NGRX, see this gist.

File structure for a "settings" store:

mkdir -p src/stores/settings

touch src/stores/settings/settings.actions.ts
touch src/stores/settings/settings.model.ts
touch src/stores/settings/settings.reducer.ts
touch src/stores/settings/settings.effects.ts

To integrate a new store:

1. Create new store directory and files
   • Minimum: action and reducer files
2. Modify src/app/app.module.ts
   • Import store effects, add to EffectsModule.forRoot([])
   • Modify the initialState{} StoreModule if needed
3. Modify src/stores/index.ts
   • Import store reducer and actions
   • Add store.State to State interface
   • Add store.reducer to reducers: ActionReducerMap
   • Add store key (as defined in reducers) to storageSyncReducer
   • Add Store state accessors as needed

Ionic Framework does not include a testing framework by default.

If you decide to set tests up, see the following testing documents:

• ngrx/platform/store
• ngrx/platform/effects
