Add Backend for User Data Synchronization

[iqbaleff214]

Currently, our Ngebanjar operates solely on the client side using the Svelte framework. We need to enhance the functionality by adding a backend system to synchronize user data across sessions and devices.

Goals:

• User Data Persistence: Implement a backend database to store user progress, quiz results, and other relevant data.
• Cross-Device Sync: Ensure that users can access their progress and continue learning seamlessly across different devices.
• Scalability: Design the backend architecture to handle a growing user base and future feature expansions.
• Security: Implement authentication and authorization mechanisms to protect user data and ensure privacy.

Proposed Solution:

• Choose a suitable backend technology stack (e.g., Node.js with Express, Django, Laravel, Firebase) based on scalability, ease of development, and compatibility with our existing frontend (Svelte).
• Design and develop RESTful APIs for user authentication, data synchronization, and CRUD operations for user-related data.
• Integrate the backend with our existing frontend codebase to enable seamless communication and data exchange.
• Implement data validation, error handling, and security measures (e.g., HTTPS, JWT tokens) to protect user data and enhance the overall user experience.

Expected Outcome:

With the backend integration, users will experience improved data synchronization, allowing them to track their progress accurately and continue learning Banjar seamlessly across different devices.

Additional Notes:

Consider scalability and performance optimizations to handle concurrent user requests and ensure a smooth user experience.
Regularly test and monitor the backend system for performance bottlenecks, security vulnerabilities, and overall reliability.
