Summary

Adds first-class support for REDIS_URL connection strings and TLS/SSL encryption (rediss://), enabling seamless integration with cloud-hosted Redis providers such as Upstash and Render Key Value.

Key Changes

• Environment Configuration (env.config.ts):
  • Added auto-parsing for REDIS_URL to automatically extract hostname, port, and password credentials while retaining backward compatibility with standalone REDIS_HOST, REDIS_PORT, and REDIS_PASSWORD variables.
• Cache Service (cache.service.ts):
  • Enhanced Redis initialization to directly connect via connection string URL, automatically enabling TLS when rediss:// protocol is provided.
  • Maintained in-memory fallback mechanism when Redis is unavailable or disabled.
• Webhook Queue (webhook-queue.service.ts):
  • Added conditional TLS configuration (tls: {}) for BullMQ queue connections when connecting to secured Redis endpoints.
• Documentation & Examples:
  • Updated .env.example to document REDIS_URL usage.
