Infra

Infra is a set of go libraries to unify the way we write grpc servers, access various databases, etc.

Installation

go get github.com/pushwoosh/infra

Libraries

All databases and brokers libraries have similar design: each library has NewContainer function that creates a container that holds named connections to the database.

To create a new connection, call Connect method. To fetch a connection, call Get method.

Databases

• Postgres - based on jackc/pgx
• Clickhouse
• MongoDB
• Redis - based on go-redis v9 driver

Message Brokers

• RabbitMQ
• Apache Kafka - based on segmentio/kafka-go
• NATS

Servers

• HTTP - http server helpers
• gRPC - gRPC server utilities for creating gRPC servers and gRPC gateways
  • gRPC middlewares - set of standard middlewares
• Info - server info endpoint. provides endpoints for k8s liveness and readiness probes, pprof, build info

Other

• GRPC Client - has same interface as database and broker libraries
• Log - zap logger wrapper
• Netretry - retry lib for temporary network errors
• Prometheus pushgateway client - client for pushgateway, mostly used in cronjobs
• Operator
• System - OS signal handler
