Handler options

type Option struct { // log level (default: debug) Level slog.Leveler

// URL Endpoint string Timeout time.Duration // default: 10s

// optional: customize webhook event builder Converter Converter // optional: custom marshaler Marshaler func(v any) ([]byte, error) // optional: fetch attributes from context AttrFromContext []func(ctx context.Context) []slog.Attr

// optional: see slog.HandlerOptions AddSource bool ReplaceAttr func(groups []string, a slog.Attr) slog.Attr }

Other global parameters:

slogwebhook.SourceKey = "source" slogwebhook.ContextKey = "extra" slogwebhook.ErrorKeys = []string{"error", "err"} slogwebhook.RequestIgnoreHeaders = false

Supported attributes

The following attributes are interpreted by slogwebhook.DefaultConverter:

Atribute name slog.Kind Underlying type
"user" group (see below)
"error" any error
"request" any *http.Request
other attributes *

Other attributes will be injected in extra field.

Users must be of type slog.Group. Eg:

slog.Group("user", slog.String("id", "user-123"), slog.String("username", "samber"), slog.Time("created_at", time.Now()), )

Example

import ( "fmt" "net/http" "time"

slogwebhook "github.com/samber/slog-webhook/v2"

"log/slog"

)

func main() { url := "https://webhook.site/xxxxxx"

logger := slog.New(slogwebhook.Option{Level: slog.LevelDebug, Endpoint: url}.NewWebhookHandler()) logger = logger.With("release", "v1.0.0")

req, _ := http.NewRequest(http.MethodGet, "https://api.screeb.app", nil) req.Header.Set("Content-Type", "application/json") req.Header.Set("X-TOKEN", "1234567890")

logger. With( slog.Group("user", slog.String("id", "user-123"), slog.Time("created_at", time.Now()), ), ). With("request", req). With("error", fmt.Errorf("an error")). Error("a message") }

Output:

{ "error": { "error": "an error", "kind": "*errors.errorString", "stack": null }, "extra": { "release": "v1.0.0" }, "level": "ERROR", "logger": "samber/slog-webhook", "message": "a message", "request": { "headers": { "Content-Type": "application/json", "X-Token": "1234567890" }, "host": "api.screeb.app", "method": "GET", "url": { "fragment": "", "host": "api.screeb.app", "path": "", "query": {}, "raw_query": "", "scheme": "https", "url": "https://api.screeb.app" } }, "timestamp": "2023-04-10T14:00:0.000000", "user": { "id": "user-123", "created_at": "2023-04-10T14:00:0.000000" } }

Tracing

Import the samber/slog-otel library.

import ( slogwebhook "github.com/samber/slog-webhook" slogotel "github.com/samber/slog-otel" "go.opentelemetry.io/otel/sdk/trace" )

func main() { tp := trace.NewTracerProvider( trace.WithSampler(trace.AlwaysSample()), ) tracer := tp.Tracer("hello/world")

ctx, span := tracer.Start(context.Background(), "foo")
defer span.End()

span.AddEvent("bar")

logger := slog.New(
    slogwebhook.Option{
        // ...
        AttrFromContext: []func(ctx context.Context) []slog.Attr{
            slogotel.ExtractOtelAttrFromContext([]string{"tracing"}, "trace_id", "span_id"),
        },
    }.NewWebhookHandler(),
)

logger.ErrorContext(ctx, "a message")

}
