Interface: KernelLogger ​
Defined in: kernel/src/logger.ts:181
Kernel logger interface with structured logging and context injection.
Loggers automatically inject execution context (requestId, traceId, etc.) from the current KernelContext via AsyncLocalStorage.
Example ​
const log = Logger.get();
// Simple message
log.info('Request received');
// With structured data
log.debug({ userId, action }, 'Processing action');
// Create child logger with bindings
const reqLog = log.child({ requestId: 'abc-123' });
// Check level before expensive operation
if (log.isLevelEnabled('trace')) {
log.trace({ fullState: getState() }, 'State dump');
