gRPC

A utility module, largely taken from the go-micro patterns (and a good amount of code too...) with pure gRPC ecosystem modules.

Principles:

• Pluggable
• No singleton

Features:

• simple configuration with options
• embeded gorm database with options (branch db)
• simple TLS configuration
• TLS auth
• client connection pool
• registry / resolver resolution
  • mdns
  • kubernetes
• default interceptors implementation:
  • validation
  • health
  • context logger
  • sentry
  • rate-limiting
  • auth claim in context
  • recovery
  • tracing (open-tracing)
  • metrics (prometheus)
  • retries
  • context DB / transaction
  • ...
• api gateway with middleware:
  • auth
  • cors
  • logging
  • tracing
  • metrics
• broker, based on nats-streaming
