golang-samber-slog

Route Go slog logs to different sinks by composing predicate-based routing pipelines using slog-multi Router/FirstMatch patterns, directing errors to Sentry, info to Loki, and warnings to Slack.

Control log volume in Go slog pipelines by applying the slog-sampling middleware as the outermost layer in your composable pipeline, filtering high-throughput logs before they reach formatting and routing stages.

Yes, samber slog integrates with HTTP middleware through slog-gin, slog-chi, and slog-echo, enabling request logging within your composable Go slog pipeline for observable services.

Composing samber slog pipelines requires Go 1.21 or higher and the versioned slog libraries for slog-multi, slog-sampling, and slog-formatter to function correctly.

Format Go slog entries by inserting the slog-formatter middleware into your pipeline, scrubbing sensitive data and standardizing log structures before routing them to targeted sinks.

Use slog-multi over standard slog when your Go service requires composable multi-step pipelines for high-throughput logs, combining predicate-based routing, volume sampling, and multi-backend sinks.
