class LogWritermethod

warning()

Writes a log message with severity ‘warning’ (3).

warning(message: unknown, ...data: unknown[]): void;

Notes

• The specified message may be a string, a DeferredString (the result of fmt()), an Error instance, or any other value that can be converted to a string.
• For DeferredString and AppException messages, placeholder values are included in the message data so that they can be stored separately in a structured log.

Examples

// Write a formatted log message
app.log.warning(fmt("User not found: {name}", userData));
