logenricher is tiny package enabling log/slog logs enrichment with data
from context.
Use cases:
- correlation id enrichment
- span and trace id enrichment
Example:
package main
import (
"context"
"log/slog"
"github.com/google/uuid"
"github.com/prathoss/logenricher"
)
func CorrelationIDExtractor(ctx context.Context) []slog.Attr {
correlationID := ctx.Value("correlation-id").(uuid.UUID)
return []slog.Attr{slog.String("correlation_id", correlationID.String())}
}
func main() {
slog.SetDefault(slog.New(&logenricher.SlogHandlerWrapper{
Handler: slog.NewTextHandler(
os.Stdout,
&slog.HandlerOptions{},
),
Extractors: []logenricher.Extractor{
CorrelationIDExtractor,
},
}))
}
