✨ Angular Material is a modern UI component library built by the Angular team, offering ready-to-use, customizable, and accessible components that follow Google’s Material Design guidelines. It helps developers create consistent, responsive, and visually appealing web applications with minimal effort.
Angular Material is an essential toolkit for Angular developers who want to build modern, responsive, and accessible applications quickly. While it enforces Material Design standards, its customization options and integration with Angular make it a powerful choice for most web projects. For developers in Costa Rica or anywhere else, adopting Angular Material means less time spent on UI design and more focus on application logic.

Let's create a sample application called myAngularApp. # Install Angular CLI cd /node/ npm install -g @angular/cli mkdir /node/myAngularApp # Create a new Angular application cd /node/ ng new myAngularApp # Run the Angular App cd /node/myAngularApp ng serve # Check at http://localhost:4200

📂 Angular profile templates:
Profiles let you quickly switch your extensions, settings, and UI layout depending on your current project or task.
To help you get started with Angular development, you can use the Angular profile template, which is a curated profile with useful extensions and settings. You can use the profile template as is or use it as a starting point to customize further for you own workflows.

Let's update myAngularApp title to "My Angular App".
Change the title string in AppComponent to "My Angular App".
Locate the file ./src/app.ts
The title is in the app.component.ts file: import { Component, signal } from '@angular/core'; import { RouterOutlet } from '@angular/router'; @Component({ selector: 'app-root', imports: [RouterOutlet], templateUrl: './app.html', styleUrl: './app.css' }) export class App { protected readonly title = signal('my Angular App'); }
You can add some components.
For example add a "home" component with:
ng generate component home
in app.ts include : import {Home} from './home/home';
in app.ts update : imports: [Home],

ng generate interface housinglocation

🧩 Example of using Angular Material in an Angular project to create a simple responsive card with a button:
This is a Material Design card App with a title, subtitle, content, and a raised button.
The button uses Angular Material’s styling (mat-raised-button) and color scheme (primary).

---

Step 1: Import a Module
Import the Material modules you need.
Locate the your app.module.ts and import the modules card and button import { MatCardModule } from '@angular/material/card'; import { MatButtonModule } from '@angular/material/button'; @NgModule({ imports: [ MatCardModule, MatButtonModule ] }) export class AppModule {}

🎨 Step 2: Use Components in HTML to build the Front-End
Here’s an example of a Material card with a button: My Angular Material Example Simple Card Demo

This is an example of a Material card with a button. Angular Material makes UI development faster and cleaner.

Angular Material also provides navigation menus, dialogs, tables, forms, inputs, validation and more.
This is a clean Material Design form with outlined input fields.
Built-in validation messages for required fields, email format, and password length.
A submit button that only activates when the form is valid.
This example use Angular Material with forms, inputs, validation, and a submit button:

📂 Step 1: Import Required Modules
In app.module.ts, import the form and Angular Material modules: form-field, input and button. import { FormsModule, ReactiveFormsModule } from '@angular/forms'; import { MatFormFieldModule } from '@angular/material/form-field'; import { MatInputModule } from '@angular/material/input'; import { MatButtonModule } from '@angular/material/button'; @NgModule({ imports: [ FormsModule, ReactiveFormsModule, MatFormFieldModule, MatInputModule, MatButtonModule ] }) export class AppModule {}

🧩 Step 2: Create a Reactive Form
In app.component.ts: import { Component } from '@angular/core'; import { FormBuilder, Validators } from '@angular/forms'; @Component({ selector: 'app-root', templateUrl: './app.component.html' }) export class AppComponent { constructor(private fb: FormBuilder) {} profileForm = this.fb.group({ name: ['', Validators.required], email: ['', [Validators.required, Validators.email]], password: ['', [Validators.required, Validators.minLength(6)]] }); onSubmit() { if (this.profileForm.valid) { console.log(this.profileForm.value); } } }

🎨 Step 3: Form Template
In app.component.html:

Name Name is required Email Email is required Invalid email format Password Password is required Minimum 6 characters Submit

You can also extend this example into a multi-step form with Angular Material’s stepper component. That’s often used for registration or checkout flows.

This is a full-stack example that combines Angular Material for the front-end with SQLite for the back-end, managing a simple Users database.
Backend (Node.js + SQLite): Stores users in a database with REST API endpoints.
Frontend (Angular + Angular Material): Displays users in a Material table and allows adding new users via a form.

🖥️ Backend: Node.js + Express + SQLite
Step 1: Install Dependencies
npm install express sqlite3 cors

---

// Step 2: Create server.js const express = require('express'); const sqlite3 = require('sqlite3').verbose(); const cors = require('cors'); const app = express(); app.use(cors()); app.use(express.json()); // Connect to SQLite const db = new sqlite3.Database('./users.db', (err) => { if (err) console.error(err.message); console.log('Connected to SQLite database.'); }); // Create Users table db.run(`CREATE TABLE IF NOT EXISTS users ( id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT NOT NULL, email TEXT UNIQUE NOT NULL )`); // API: Get all users app.get('/users', (req, res) => { db.all(`SELECT * FROM users`, [], (err, rows) => { if (err) return res.status(500).json({ error: err.message }); res.json(rows); }); }); // API: Add new user app.post('/users', (req, res) => { const { name, email } = req.body; db.run(`INSERT INTO users(name, email) VALUES(?, ?)`, [name, email], function(err) { if (err) return res.status(500).json({ error: err.message }); res.json({ id: this.lastID, name, email }); }); }); app.listen(3000, () => console.log('Server running on http://localhost:3000'));

🎨 Frontend: Angular + Angular Material
Step 1: Install Angular Material ng add @angular/material

Step 2: Import Modules
In app.module.ts: import { HttpClientModule } from '@angular/common/http'; import { MatTableModule } from '@angular/material/table'; import { MatFormFieldModule } from '@angular/material/form-field'; import { MatInputModule } from '@angular/material/input'; import { MatButtonModule } from '@angular/material/button'; @NgModule({ imports: [ HttpClientModule, MatTableModule, MatFormFieldModule, MatInputModule, MatButtonModule ] }) export class AppModule {} Step 3: Component Example In app.component.ts: import { Component, OnInit } from '@angular/core'; import { HttpClient } from '@angular/common/http'; @Component({ selector: 'app-root', templateUrl: './app.component.html' }) export class AppComponent implements OnInit { users: any[] = []; name = ''; email = ''; constructor(private http: HttpClient) {} ngOnInit() { this.loadUsers(); } loadUsers() { this.http.get('http://localhost:3000/users').subscribe(data => this.users = data); } addUser() { this.http.post('http://localhost:3000/users', { name: this.name, email: this.email }) .subscribe(() => { this.name = ''; this.email = ''; this.loadUsers(); }); } }

---

Step 4: Template with Angular Material In app.component.html: Name Email Add User ID {{user.id}} Name {{user.name}} Email {{user.email}} You can extend this into a multi-step Angular Material form with validation that connects to the SQLite backend, so you can handle more complex user registration flows (like password, role, etc.)?

This is an example of accessing a SQLite database in a Node.js environment.
SQLite is lightweight and perfect for small to medium applications, or for prototyping.
📦 Step 1: Install SQLite Package
Run this in your project folder: npm install sqlite3
