S Sport (wap 2g) Recipe

Create project skeleton

Initialize a new web application repository. Install Node.js and your package manager. Scaffold the WAP 2G base project structure (src, services, api, frontend, tests). Configure TypeScript if using it and set up linting and formatting tools.

Install runtime dependencies for both backend and frontend (HTTP server, framework, bundler). Commit initial scaffold to source control.

Event catalog

Design the event model (sport, league, eventId, teams/players, startTime). Implement services to import and normalize event data from the sports data provider. Build database schemas and indexes for quick lookups.

Odds engine

Implement an odds representation that supports decimal, fractional, and American formats. Create routines to ingest odds from provider and convert formats. Add derived computations (implied probability, margin). Ensure odds updates are versioned and timestamped.

Bet slip module

Create a bet slip API allowing users to build single/multi bets, calculate potential returns, and validate stake/limits. Implement server-side validation for market status (open/closed), min/max stake, and accepted odds. Provide endpoints for place, modify, and cancel actions with idempotency keys.

User account & wallet

Implement authentication and wallet ledger. Ensure transactional integrity when reserving funds for bets (reserve before accepting a bet). Record transactions (deposit, withdrawal, bet reserved, bet settled) with unique IDs and timestamps. Expose endpoints for balance and transaction history.

Live feed & settlement

Integrate live/in-play feeds using WebSocket or streaming API. Update odds and market states in real time. Implement a results consumer that receives official outcomes and triggers settlement logic to mark bets as won/lost/push and update user balances.

Provider integration

Configure authenticated connections to chosen sports data providers. Implement adapters to normalize provider-specific payloads into your event and market models. Add retry/backoff logic and health checks for provider endpoints.

Real-time messaging

Set up a real-time layer (WebSocket/Socket.IO or pub/sub) for pushing updates to clients: odds changes, market suspension, bet confirmations, and live scores. Ensure scale by using a message broker (Redis, Kafka) for distribution.

Payments & KYC

Integrate payment gateways for deposits and withdrawals with proper webhook handling and reconciliation. Integrate KYC provider APIs to verify user identity and tie verification status to account actions (withdrawal limits, eligibility).

Authentication & authorization

Implement secure auth using OAuth2 or JWT with refresh tokens. Enforce role-based access control for admin endpoints. Store secrets securely and rotate keys periodically.

Validation & rate limiting

Add strong input validation on all endpoints, sanitize incoming data, and apply rate limiting to public APIs to prevent abuse. Log suspicious activity and integrate with WAF if required.

Audit & responsible gaming

Keep an immutable audit trail for all financial and betting operations. Implement responsible gaming features: deposit limits, bet limits, session timeouts, self-exclusion workflow, and visible help links. Ensure compliance with regional regulations.

Frontend implementation

Build responsive UI components for the event list, market rows, odds display, and bet slip. Make the bet slip update in real time as users select markets and adjust stake. Provide clear error messaging and confirmations for critical actions.

Localization & mobile

Implement i18n and multi-currency formatting. Make the app mobile-first and consider packaging as a PWA for offline and push capabilities.

Testing

Write unit tests for core logic (odds conversion, settlement, wallet ledger). Create integration tests that simulate provider data and full bet lifecycle. Run end-to-end tests for common user flows (signup, deposit, place bet, settlement).

CI/CD and deployment

Create CI pipelines to lint, test, and build artifacts. Use container images and deploy to orchestrated infrastructure (Kubernetes) with blue/green or canary strategies. Monitor application health, latency, and business KPIs (bets per minute, hold, revenue).
