How do I build your first app: houses for rent tutorial?

Follow official interactive tutorial at [angular.dev/tutorials/first-app](https://angular.dev/tutorials/first-app). - Complete lessons on components, templates, signals. - Build app listing houses with details view. - Key: Use `@Component`, `signal()`, template binding. Example component: ```typescript import { Component, signal } from '@angular/core'; @Component({ selector: 'app-root', template: ` {{title()}} `, }) export class AppComponent { title = signal('Houses'); } ```

How do I master components, signals, and templates?

Study [Essentials](https://angular.dev/essentials): - **Components**: Build reusable UI with `@Component`. - **Signals**: `signal()`, `computed()` for reactivity. - **Templates**: Interpolation `{{}}`, `*ngFor`, `@if`. Practice: ```typescript houses = signal([{id:1, name:'House1'}]); ``` Template: ```html @if (houses().length) { {{house.name}} } ```

How do I add forms, services, and dependency injection?

Extend your app: - Generate service: `ng generate service house` - Use DI: Inject in constructor. - Signals forms from essentials. Example service: ```typescript import { Injectable, signal } from '@angular/core'; @Injectable({providedIn: 'root'}) export class HouseService { houses = signal([]); loadHouses() { /* fetch */ } } ``` Inject: `constructor(private houseService: HouseService) {}`

How do I implement routing and deploy your project?

Add routing: `ng generate module app --routing` app.routes.ts: ```typescript import { Routes } from '@angular/router'; export const routes: Routes = [{path: 'houses/:id', loadComponent: () => import('./house-detail.component')}]; ``` Bootstrap in main.ts. Build & Deploy: ```bash ng build ``` Serve `dist/` folder or host on GitHub Pages/Netlify.
