Log

Log middleware is used to log incoming requests and outgoing responses.
It helps in monitoring and debugging your application by providing insights into the request lifecycle.

Default log uses slog to print logs in debug mode.

mlog "github.com/rakunlabs/ada/middleware/log"

Add middleware to directly mux, group or handle; usually placed in the top of the middleware chain:

mlog.Middleware()

Example output:

2025-11-01 18:35:33 CET DBG log/log.go:101 request user="" route=/ request_id=01K907T8BP43F4S0M30QE37J07 remote_ip=[::1]:34186 host=localhost:8080 method=GET uri=/ user_agent=Mozilla/5.0 status=200 latency=276713 latency_human=276.713µs bytes_in="" bytes_out=29

Configuration

You can configure the middleware using mlog.Option functions.

// skipper example to show skip logging for GET requests
mlog.Middleware(mlog.WithSkipper(func(r *http.Request) bool {
    if r.Method == http.MethodGet {
        return true
    }

    return false
}))

This logger also adds request_id, user and user_agent fields to the log context if available.

Use our logi package to make context-aware logging in your handlers:

// import "github.com/rakunlabs/logi"
logi.Ctx(r.Context()).Info("saying hello")
