Master Angular: From Component Trees to Production Architecture

Progress Status0 / 24 Units

1. The Angular Mental Model

How Angular Actually Works — Components, Trees, and Bootstrapping

Passing Data Between Components — Inputs, Outputs, and the Event Contract

NgModule — The Dependency Registry You Can't Ignore

2. Templates, Directives, and Data Flow

Built-in Directives — Controlling the DOM Without Touching It

Template Syntax Deep Dive — Binding, References, and Two-Way Data Flow

Pipes — Transforming Data in Templates Without Polluting Components

3. Services, DI, and Forms

Services and Dependency Injection — Building the Singleton Layer

Reactive Forms — Modeling Forms as Data Structures

DI Patterns — Factories, Tokens, and Swapping Implementations

4. Reactive Programming with RxJS

RxJS Observables — Thinking in Streams

BehaviorSubject and State Streams — Services as Observable Data Sources

The Operation Stream Pattern — Managing Complex State with RxJS

5. HTTP, Routing, and Guards Source

HttpClient — Making Real API Calls the Angular Way

Routing — Navigating a Multi-Page Application

Route Guards — Protecting Routes and Resolving Data

6. Advanced Components and Change Detection Source

Advanced Components — Host Elements, Content Projection, and Lifecycle Hooks

Change Detection — Default, OnPush, and When Things Go Silent

7. State Architecture — Redux in Angular Source

Introduction to Redux — Pure Functions, Reducers, and Immutable State

Redux in Angular — Connecting the Store to Components

Redux Architecture — Reducers, Selectors, and the AppState Shape

Container vs. Presentational Components — Scaling Redux Cleanly

8. Testing

Testing Services — Mocking HTTP and Isolating Dependencies

Testing Components — DOM Interaction and Routing

Testing Forms — Simulating Input, Validations, and Submissions

“Mastery is not a destination, but a continuous journey of excellence.”

DI Patterns — Factories, Tokens, and Swapping Implementations

Move beyond basic service injection and take control of exactly how Angular creates and delivers dependencies. After this lesson you'll use useClass, useValue, useFactory, and InjectionToken to build configurable services, inject environment-specific values, and swap implementations without touching consumer code.
