go-libs

go-libs is a monorepo of focused Go modules for building and operating services. Each top-level module is versioned independently with tags named <module>/vX.Y.Z.

Installation

Install only the module you need:

go get github.com/devctllabs/go-libs/<module>@latest

Modules

Application foundations

Module	Description

retry	Explicit context-aware retry loops and capped exponential backoff.

Operations and observability

Module	Description
buildinfo	Build metadata embedded in the current Go executable.
debugserver	A standalone HTTP server for Go pprof endpoints.

Module	Description
health	Transport-neutral liveness and readiness probes.
healthgrpc	Standard gRPC Health service backed by transport-neutral probes.
healthotel	OpenTelemetry metrics for health check observations.
healthserver	OpenAPI-generated Echo endpoints for liveness and readiness probes.
healthzap	Structured zap logging for health check failures and recoveries.

gRPC

Module	Description
grpcclient	Explicit gRPC client connections with file-backed TLS, interceptor chains, and opt-in OpenTelemetry.
grpcserver	Application-owned gRPC runtime with validation, panic recovery, reflection, TLS, and graceful shutdown.
grpczap	Completion and recovered-panic logging adapters for zap.

Messaging

Module	Description
kafka	Typed franz-go producer and batching consumer runtimes with JSON codecs, retry, reject/DLQ policy, and OpenTelemetry.
kafkaproto	Protobuf encoders and fresh-message decoders for Kafka values.
kafkazap	Structured zap logging for Kafka consumer retries and dispositions.
kafkaoutbox	PostgreSQL transactional outbox with polling virtual shards or Debezium CDC delivery.
kafkaoutboxzap	Structured zap logging for outbox retries, fencing, and topology changes.

Data and infrastructure

Module	Description
dbmigrate	Recursive SQL migration selections over fs.FS, executed by golang-migrate.
filesystem	Rooted filesystem operations that compose with the standard io/fs package.
postgresdb	Instrumented pgx reader and writer pools for PostgreSQL.
sqlitedb	Instrumented SQLite reader and writer endpoints.
txmanager	Shared transaction boundaries for services and database adapters.

Identity and API security

Module	Description
oapivalidator	OpenAPI request validation and authentication middleware for Echo.
oapivalidatorjwt	JWT bearer and cookie authenticator for oapivalidator.
oidcsession	OIDC provider lifecycle, encrypted login state, and browser session HTTP flows.
oidcsessionredis	Redis-backed opaque refresh sessions with encrypted provider tokens.

Development

The repository pins its development tools with mise:

mise install
mise run lint
mise run test:race
mise run check-generated

Run the relevant integration suite separately (Docker required):

mise run postgresdb:test-integration
mise run dbmigrate:test-integration
mise run oidcsessionredis:test-integration
mise run kafkaoutbox:test-integration

Releases

Modules are released independently. Release notes are generated on demand and tags follow the <module>/vX.Y.Z convention. See RELEASING.md for the release process and module dependency order.
