 class CodelabsLogFormatter implements ILogFormatter { format(data: LogData): string { return `[employee-service]:[${data.level}] ${JSON.stringify(data)}`; } } const destination = CodelabsLogFormatter({ formatter: new KrishLogFormatter(), }); export const logger = pino( {level: process.env.LOG_LEVEL || 'info'}, destination );
