GitSpy — GitHub API Middleware

GitSpy is an intermediary API that centralizes and optimizes GitHub API calls through a multi-layer caching system, event queue, and intelligent rate limit control. It includes webhook handlers, Prometheus metrics, and a comprehensive test suite.

Highlights

• Express Server with endpoints for webhooks, repositories, and metrics.
• GitHub Integration via adapter with rate limit handling.
• Redis Caching with Fail-open Strategy: Transparently bypasses Redis on connection failure to maintain availability.
• Proactive Invalidation: Removes stale keys after successful mutations, prioritizing eventual consistency.
• Hard Limits: Webhook payloads capped at 1MB to protect memory stability.
• Event Queue with BullMQ and workers for asynchronous processing.
• Metrics and monitoring (Prometheus) and 70+ tests strategy.
• Non-Custodial Architecture: Auth tokens are passed via encrypted headers and never persisted to disk.
