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.”

Testing Components — DOM Interaction and Routing

Verify that your components render the right DOM output, respond correctly to user interaction, and navigate to the right routes — without a browser. After this lesson you'll use ComponentFixture, debugElement, and RouterTestingModule to write component tests that catch real rendering bugs and routing failures.
