The fitness tracker application uses Angular for the frontend, featuring Angular Material for UI components, RxJS for reactive programming, Angular Router for navigation, and NgRx for state management. The backend is built with Node.js and Express.js, while MongoDB handles the database. Authentication is managed with JSON Web Tokens (JWT) and Passport.js. Integration includes Fitness Data APIs and Maps APIs. Testing is done with Jasmine, Karma, and Protractor. Deployment utilizes Docker and cloud services (AWS, Azure, Google Cloud). Real-time data processing is achieved with WebSockets, and push notifications with Firebase Cloud Messaging (FCM). CI/CD pipelines are automated with Jenkins, GitHub Actions, or GitLab CI. Monitoring and logging use the ELK Stack and Prometheus/Grafana. Security is ensured through HTTPS, Content Security Policy (CSP), and data encryption. Responsive design (Bootstrap/Tailwind CSS) and ARIA enhance UX and accessibility, while user analytics are tracked with Google Analytics or Mixpanel.…The fitness tracker application uses Angular for the frontend, featuring Angular Material for UI components, RxJS for reactive programming, Angular Router for navigation, and NgRx for state management.
