// Package logz provides structured logging backed by [log/slog].
|
||
|
|
//
|
||
|
|
// Create a logger with [New]:
|
||
|
|
//
|
||
|
|
// logger := logz.New(logz.Options{
|
||
|
|
// Level: slog.LevelDebug,
|
||
|
|
// JSON: true,
|
||
|
|
// StaticArgs: []any{"service", "api", "env", "production"},
|
||
|
|
// })
|
||
|
|
//
|
||
|
|
// Log at any level:
|
||
|
|
//
|
||
|
|
// logger.Info("server started", "port", 8080)
|
||
|
|
// logger.Error("request failed", err, "path", "/users")
|
||
|
|
//
|
||
|
|
// Errors that implement ErrorCode() and ErrorContext() are automatically
|
||
|
|
// enriched — the error code and context fields are added to the log record
|
||
|
|
// without any extra method calls. This pairs naturally with xerrors.Err.
|
||
|
|
//
|
||
|
|
// Attach request context to a child logger:
|
||
|
|
//
|
||
|
|
// ctx = logz.WithRequestID(ctx, requestID)
|
||
|
|
// ctx = logz.WithField(ctx, "user_id", userID)
|
||
|
|
// reqLogger := logger.WithContext(ctx)
|
||
|
|
// reqLogger.Info("handling request")
|
