🚀 Install

go get github.com/samber/slog-sentry

Compatibility: go >= 1.20.3

This library is v0 and follows SemVer strictly. On slog final release (go 1.21), this library will go v1.

No breaking changes will be made to exported APIs before v1.0.0.

💡 Usage

GoDoc: https://pkg.go.dev/github.com/samber/slog-sentry

Handler options

type Option struct {
    // log level (default: debug)
	Level     slog.Leveler
    // sentry hub (default: current hub)
	Hub       *sentry.Hub

    // optional: customize Sentry event builder
	Converter Converter
}

Supported attributes

The following attributes are interpreted by slogsentry.DefaultConverter:

Atribute name	`slog.Kind`	Underlying type
"dist"	string
"environment"	string
"event_id"	string
"platform"	string
"release"	string
"server_name"	string
"tags"	group (see below)
"transaction"	string
"user"	group (see below)
"error"	any	`error`
"request"	any	`*http.Request`
other attributes	*

Other attributes will be injected in extra Sentry field.

Users and tags 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()),
)

The Sentry agent is responsible for collecting context and modules.

Example

import (
	"github.com/getsentry/sentry-go"
	slogsentry "github.com/samber/slog-sentry"
	"golang.org/x/exp/slog"
)

func main() {
    err := sentry.Init(sentry.ClientOptions{
        Dsn:           myDSN,
        EnableTracing: false,
    })
    if err != nil {
        log.Fatal(err)
    }

    defer sentry.Flush(2 * time.Second)

    logger := slog.New(slogsentry.Option{Level: slog.LevelDebug}.NewSentryHandler())
    logger = logger.
        With("environment", "dev").
        With("release", "v1.0.0")

    // log error
    logger.
        With("category", "sql").
        With("query.statement", "SELECT COUNT(*) FROM users;").
        With("query.duration", 1*time.Second).
        With("error", fmt.Errorf("could not count users")).
        Error("caramba!")

    // log user request
    logger.
        With(
            slog.Group("user",
                slog.String("id", "user-123"),
                slog.Time("created_at", time.Now()),
            ),
        ).
        With("request", httpRequest)
        With("status", 200).
        Info("received http request")
}
