Lightweight

A concise core built on the Go standard library and a small set of hand-picked dependencies. No framework lock-in.

Interface-based component system. Declare components with weaver.Implements and let weaver generate wire up registration code.

Declare dependencies with weaver.Ref and the framework builds the component graph, instantiating on demand.

Built on the standard library slog, with automatic TraceID / SpanID and rotating, compressed file output.

First-class distributed tracing with logs automatically correlated to traces.
