Overview
Aurum FrontEnd — Real‑time Investment Dashboard. React frontend for portfolio tracking and real-time quotes, focusing on network resilience, responsive UX and extensible architecture. Integrates WebSockets for market streaming and REST API for secure operations.
Aurum BackEnd — Server-Socket and request management of multiple APIs, with request control. Developed with technologies NestJS, Redis, Bull, Docker, MongoDB, typescript class-validator among others.
Main Features
- Realtime: Ticker and price updates via Socket.IO (controlled reconnection, backoff, event‑driven).
- Request deduplication: same logical key → one call, multiple consumers; 60s global timeout.
- Network resilience: socket URL fallback, connection wait, consistent 4xx/5xx handling.
- Structured errors + custom translation structure: backend returns (status, message); UI translates by status (ex.: error.401) with fallback.
- UX: loading states, technical message filtering (ex.: hides "socket not connected"), optimized dark mode.
Relevant Technical Decisions
- Socket Singleton: isConnectingRef + connected checks prevent duplicate connections.
- Timeouts and Retries: AbortController/timeouts in fetch; global timeout in WebSocket flows.
- Standardized errors: always throws object with status/message for predictability.
- Robust configuration: getSocketUrl derives fallback from API_URL and environment (dev/prod).
Security and Best Practices
- No keys on client: environment variables; no sensitive logic on frontend.
- Error isolation: internal messages don't leak; UI filters technical noise.
- Scalable architecture: specialized contexts, pure functions for APIs, decoupled components.
Metrics and Performance (indicative)
- Unique WebSocket connections per session/component.
- Reduction of redundant calls with deduplication.
- Reduced perceived latency via streaming + pre-loading on visibility.
Differentials
- Above-average network robustness: avoids socket race conditions, promise hangs and reconnection loops.
- Product-level error and UX: user-friendly messages, clear diagnostics for devs.
- Ready for evolution: data provider changes and new features without breaking internal contracts.
Key Advantage – Efficient API Management
Aurum was built with a focus on performance and scalability. Through optimized API resource management, the system:
- Reduces the number of external requests.
- Distributes data faster and more efficiently to clients.
- Improves response times and overall user experience.
- Ensures greater system stability even with high demand.
This makes Aurum not only a powerful investment management platform, but also a high-performance solution for real-time financial data distribution.
