Situation (basic store setup)

1. We have an empty angular app with eagerly loaded module called posts
2. We want to add @ngrx/store and @ngrx/store-devtools
3. Get familiar with Redx DevTools: https://chrome.google.com/webstore/detail/redux-devtools/lmhkpmbekcpmknklioeibfkpmmfibljd?hl=en
4. Add minimal setup to start using store
5. Check that state is properly initialized using store-devtools
6. Display data from store in PostListComponent

Situation (extending initial state)

1. Create interface describing posts state. See State in posts.reducer.ts-node
2. Create initialState and use it to initalize your store.

---

Situation (display posts state in component)

1. Select state from store and display it (no typing at the moment)

Situation (add types)

1. Create global appState
2. Apply types on store and state selection
3. Show different ways to read state

Situation (introducing actions)

1. Create actions and update posts reducer
2. Dispatch actions from component
3. Observe store state modifications in Store DevTools. Explore Action, State and Diff buttons

Situation (entities approach)

1. More efficient to manage large collections (faster lookups by id entities map, preserve order ids array)
2. Simpler reducer code
3. Discover adapter, selectors
