README

logmod

logmod exports logs to the otel endpoint and flushes log buffers before the application exits. After logmod.New() runs, slog calls are routed through the otelslog bridge.

	"github.com/go-srvc/mods/logmod"
	"github.com/go-srvc/mods/sigmod"
	"github.com/go-srvc/srvc"
)

func main() {
	srvc.RunAndExit(
		logmod.New(),
		sigmod.New(os.Interrupt),
		httpmod.New(
			httpmod.WithAddr(":8080"),
			httpmod.WithHandler(http.HandlerFunc(hello)),
		),
	)
}

func hello(w http.ResponseWriter, r *http.Request) {
	slog.InfoContext(r.Context(), "request", "path", r.URL.Path)
	fmt.Fprint(w, "ok")
}
