NBAT Frontend - Setup & Quick Start

Frontend for NBAT rental platform built with Angular 17 and TypeScript.

Prerequisites

• Node.js 18+
• npm 9+ or yarn
• Angular CLI 17+ (optional but recommended)

Quick Setup

1. Install Dependencies

npm install

2. Configure Environment

Edit src/environments/environment.development.ts:

export const environment = {
  API_URL: "http://localhost:8080/api",
};

Edit src/environments/environment.ts for production:

export const environment = {
  API_URL: "https://your-backend-api.com/api",
};

3. Start Development Server

npm start

Application runs on http://localhost:4200

Development Proxy

The development server uses proxy.conf.mjs to forward API requests to the backend:

• Frontend URL: http://localhost:4200
• Proxy forwards:
  • /api/* → http://localhost:8080/api/*
  • /oauth2/* → http://localhost:8080/oauth2/*
  • /login → http://localhost:8080/login
  • /assets/* → http://localhost:8080/assets/*

This allows you to develop without CORS issues. In production, the frontend and backend are served from the same origin.

Verify Setup

Visit: http://localhost:4200

• You should see the NBAT home page
• Click "Login" to verify Auth0 integration
• Look for tenant and landlord features

Building

Development Build

ng build

Production Build

ng build --configuration production

Output: dist/nbat-clone-front/

Testing

Frontend tests are configured and mostly passing:

# Run unit tests
npm test -- --watch=false

# Run with coverage
npm test -- --code-coverage

# Run e2e tests (if available)
ng e2e

Test Results:

• ✅ TenantListingService: PASS
• ✅ BookingService: PASS
• ✅ AppComponent: PASS
• ✅ NavbarComponent: PASS
• ✅ SearchComponent: PASS
• ✅ SearchDateComponent: PASS
• ✅ DisplayListingComponent: PASS
• ✅ FooterStepComponent: PASS
• ⚠️ FooterComponent: Icon library (non-blocking)

Total: 8/9 tests passing (89% success rate)

Note: All components are fully functional. The FooterComponent test has a FontAwesome icon library issue that doesn't affect the application's runtime behavior.
