Angular + ngrx examples

Examples used to demonstrate Angular + ngrx use for my Reactive Angular talk (Portuguese)

##Examples

All examples are using Angular 4.x and created with Angular CLI 1.x

Counter (source)

A counter which can be incremented, decremented, with the option to increment or decrement async and reset the counter. This is the most basic ngrx example, with no ajax integration.

Demonstrates

1. Creating a basic reducer
2. Selecting a slice of state
3. Using the async pipe
4. Dispatching actions from a component

Todo CRUD (source)

Simple TODO application with CRUD operations with node backend.

Demonstrates

1. Initial reducer state
2. Managing collections in reducer
3. Using the async pipe with the enhanced ngFor (Angular >=4.x)
4. Dispatching actions from a service
5. Intercepting ajax requests with ngrx/effects
6. Sample node server API

Firebase Auth (source)

Login + Logout + Register screen using Firebase.

Demonstrates

1. Initial reducer state
2. Login screen + Register screen
3. Menu/Navbar with conditional buttons/links
4. Using the async pipe with the enhanced ngIf and ngFor (Angular >=4.x)
5. Dispatching actions
6. Intercepting ajax requests with ngrx/effects
7. Routing from ngrx/effect
8. Auth Guard using ngrx store state
9. Error handling with messages on the screen
10. Firebase

Simple LMS with Firebase (source)

Simple Learning Management System (list of courses and lessons) with login and CRUD operations using Firebase

Demonstrates

1. Initial reducer state
2. Login screen
3. Multiple reducers
4. Using the async pipe with the enhanced ngIf and ngFor (Angular >=4.x)
5. Dispatching actions from a service
6. Intercepting ajax requests with ngrx/effects
7. Firebase
8. Using ngrx platform (v4) - lazy loading of reducers and app state injection dynamically
