GoWrap
A command-line tool that generates decorators for Go interfaces using templates to add cross-cutting concerns like metrics and tracing.
What is GoWrap?
GoWrap is a command-line tool that generates decorator implementations for Go interfaces using templates. It solves the problem of manually writing repetitive boilerplate code to add cross-cutting concerns like metrics, logging, tracing, and resilience patterns to existing interfaces. By automating this process, it helps developers maintain cleaner, more focused business logic.
Go developers building services or libraries who need to add observability, resilience, or validation layers to their interfaces without cluttering core logic. It's particularly useful for teams adopting microservices or implementing consistent patterns across a codebase.
Developers choose GoWrap because it drastically reduces boilerplate, enforces consistent patterns via templates, and integrates seamlessly with Go's toolchain (like `go generate`). Its rich set of built-in templates for popular libraries (Prometheus, OpenTelemetry, logrus) means you can add production-ready features in seconds.
