What is the purpose of the router outlet in Angular?

The router outlet is used to render dynamic content based on the current route, allowing different components to be displayed as users navigate through the application.

How does Angular handle route order?

Angular checks routes sequentially, meaning that if two routes have the same path, only the first one will be rendered, potentially leading to bugs if not managed correctly.

What are dynamic parameters in Angular routing?

Dynamic parameters are placeholders in the route path that can change, allowing for flexible routing based on unique identifiers, such as page IDs.

How can we redirect users in Angular routing?

Redirecting users can be done by defining a route with an empty path and specifying the target route using the redirectTo property, allowing for seamless navigation.

What is the purpose of route guards in Angular?

Route guards are functions that check user access before allowing navigation to certain routes, ensuring that only authorized users can access specific parts of the application.

How does lazy loading improve application performance?

Lazy loading allows components to be loaded only when their corresponding routes are accessed, reducing the initial bundle size and improving the application's load time.

Angular Routing Essentials: All You Need to Know in One Video!

Core Routing Fundamentals
🗺️ Define routes using an array of objects within `provideRouter`, specifying a `path` (e.g., "dashboard") and the `component` to render.
🖥️ Use the `` tag in your main component's HTML to display dynamic content based on the active route, ensuring `RouterOutlet` is imported.
🔗 Create navigation links with `routerLink` attributes on `` tags (e.g., `routerLink="/dashboard"`), and import `RouterLink` for proper functionality.
⚠️ Route order is critical: Angular matches the first defined route, so place more specific routes before general ones to avoid unexpected overrides, especially with dynamic parameters.

Dynamic & Redirect Routing
🆔 Implement dynamic URL parameters (e.g., `/pages/:pageId`) using a colon (`:`) followed by a unique identifier in the route path.
📥 Access both dynamic and query parameters declaratively in components by defining `required` `input` signals (e.g., `@Input({ required: true }) pageId!: string`), enabled by `withComponentInputBinding` in `provideRouter`.
↩️ Configure route redirects from one path to another using `redirect to` (e.g., `path: '', redirectTo: '/dashboard', pathMatch: 'full'`) for simple cases, or a function for complex logic.
🛑 Handle not-found pages by defining a wildcard route (`path: '**'`) as the *last* route in your configuration, directing to a specific `NotFoundComponent`.

Structuring & Navigating Routes
🌳 Create nested routes by adding a `children` array to a parent route definition, requiring a `` within the parent component's template for child content.
💡 Highlight active navigation links by adding `routerLinkActive="active"` and ensure `routerLinkActiveOptions: { exact: true }` for parent routes to prevent partial matches with child routes.
➡️ Perform programmatic navigation from component logic using `router.navigateByUrl('/products')` for full URL paths or `router.navigate(['/products', 'item', itemId])` for array-based path construction.

Optimizing & Protecting Routes
⚡ Implement lazy loading for routes using `loadComponent` instead of `component`, which loads route-specific code only when accessed, significantly reducing initial bundle size.
🔒 Secure routes with Guards (e.g., `canActivate`), which are functions that check access permissions before a user can navigate to a route, redirecting or denying if conditions aren't met.

Pre-fetching Route Data
⚙️ Utilize Resolvers to pre-fetch necessary data (e.g., API calls) before a component is rendered, making that data available to the component via signal inputs.

Key Points & Insights
🚨 Always import necessary routing modules (e.g., `RouterOutlet`, `RouterLink`, `RouterLinkActive`) into the component or module where they are being used.
🚀 Leverage Angular Signals for declarative parameter access to simplify retrieving dynamic, query, and resolved data within your components, a modern and efficient approach.
⏱️ Consider lazy loading for all non-critical routes to optimize application performance and user experience by reducing initial load times and improving responsiveness.
