A demo portfolio representing a subscription-based application.
A demo portfolio representing a subscription-based application. Focused on clean state transitions, reactive forms, and modular CSS architecture.
The project demonstrates how complex multi-step subscription workflows can be structured for maintainability and clear user progression.
The problem
Complex multi-step forms and state validation are hard to maintain.
Subscription workflows often involve complex multi-step forms, state validation, and payment flows that are hard to maintain without clear structure.
- Multi-step flows can become tangled without discrete state boundaries.
- Validation logic scattered across components leads to inconsistent user feedback.
- Payment simulation requires careful state management to prevent invalid submissions.
Approach
Discrete steps with BEM modularity and reactive state management.
Broke the registration flow into discrete steps (account setup, package selection, payment, review). Used BEM for CSS modularity and reactive state management for form transitions.
Each step was designed as a self-contained unit with clear entry and exit validation criteria.
Solution
Modular Angular architecture with reactive state transitions.
Separated concerns into distinct Angular modules and services. Implemented reactive state transitions with clear guards between steps. Firebase Firestore handled subscription persistence.
The architecture ensures each subscription step is testable independently while maintaining a cohesive user journey.
Implementation
Technical implementation.
Built with Angular 17 leveraging standalone components, reactive forms with comprehensive validation, and Firebase Firestore for data persistence.
Frontend
Angular 17, TypeScript, reactive forms with validation, standalone components.
Styling
BEM methodology for modular, conflict-free CSS architecture.
Backend
Firebase Firestore for subscription data persistence and real-time updates.
Results
What changed.
The modular approach resulted in a clean, maintainable subscription flow that demonstrates best practices for complex form handling.
