@heyhru/common-util-logger

Shared logger based on pino, usable on both server and browser.

Usage

import { createLogger } from "@heyhru/common-util-logger";

const logger = createLogger({ name: "my-service" });

logger.info("server started");
logger.error({ err }, "request failed");
logger.debug({ userId }, "user login");

// Child logger with bound context
const reqLogger = logger.child({ requestId: "abc-123" });
reqLogger.info("handling request");
