Angular Course

Master Modern Web Development with Angular.

Angular is one of the world's most powerful frontend frameworks for building scalable, high-performance, and enterprise-ready web applications.

Let's install Angular and create your first project.

🚀 Welcome to your very first real Angular feature.

An Angular template is HTML with super-powers.

A component is the unit of reuse in Angular.

Data binding is how the class and the template stay in sync.

Directives attach behaviour to elements.

User events (click, input, submit, keyup) are bound with parentheses.

Modern Angular ships a built-in control-flow syntax: @if, @else if, @else, @for, @switch.

Render a list with @for.

Angular has two form systems: Template-driven (simple, declarative — good for tiny forms) and Reactive (powerful, scalable — the right pick for anything beyond a single field).

The router maps URLs to components.

A service is a plain class that holds reusable logic — auth, cart state, an API client, a logger.

Angular ships HttpClient to call REST APIs.

Pipes transform values in the template — formatting dates, currencies, percentages, JSON, async observables and more.

Components have a lifecycle: created → inputs set → rendered → updated → destroyed.

Each component can have its own scoped styles.

main.ts is the entry point.

Angular 17 introduced built-in @if / @for / @switch / @defer.

Signals are Angular's new reactive primitive (since v16, stable in v17).

Change detection is how Angular figures out which DOM bits to update.

Sometimes you need to render a component you only know about at runtime — modals, toasts, plug-in widgets, ad slots, dashboard tiles configurable by the user.

DI is hierarchical: each component has its own injector.

Beyond basic routes: guards (block access), resolvers (preload data), lazy loading (split bundles), route data + title, and component input binding so route params arrive as @In…

An interceptor is middleware for every HTTP call.

Reactive forms scale to giant, dynamic UIs.

For complex state, you have options: simple signal services (the new default for most apps), NgRx (Redux pattern, great for very large teams and complex flows), or NgRx SignalSt…

Angular wraps the Web Animations API in a declarative DSL — fade, slide, stagger lists, route transitions.

Angular ships with Jasmine + Karma out of the box (and you can swap to Jest or Vitest).

Angular sanitizes templates by default, so {{ userInput }} is XSS-safe out of the box.

Server-Side Rendering (SSR) renders your app on the server and ships HTML to the browser, then hydrates it into a live Angular app.

Angular ships an AOT (ahead-of-time) compiler.

Practice is the only way to make Angular stick.
