Logging

Pattern: Explicit Constructor Injection

Loggers are passed explicitly via constructor injection throughout the codebase. There is no global/ambient logger.

import type { Logger } from '@repo/shared';

class MyService {
  constructor(private logger: Logger) {}

  async doWork(context: WorkContext) {
    const childLogger = this.logger.child({ operation: 'work' });
    childLogger.info('Working', { context });
  }
}
