@noego/logger

Lightweight logging for Node.js with:

• level filtering (TRACE to FATAL)
• named loggers
• contextual metadata
• pluggable transports
• optional @noego/ioc integration

Install

npm install @noego/logger

Quick Start

import { getLogger, configureLogging, LogLevel } from "@noego/logger";

configureLogging({
  level: LogLevel.INFO,
  serviceName: "my-service",
});

const logger = getLogger("api");
logger.info("Server started", { port: 3000 });
logger.error("Request failed", new Error("boom"));

Context and Named Loggers

const base = getLogger("http").withContext({ requestId: "req_123" });

base.info("Incoming request");
base.named("auth").warn("Invalid token", { userId: "u_42" });

IoC Integration

import { createContainer } from "@noego/ioc";
import { registerLoggerFactory } from "@noego/logger/ioc";

const container = createContainer();
registerLoggerFactory(container, Symbol.for("app:logger"), "app");

API

• getLogger(name) -> logger instance
• configureLogging(options) -> configure global manager
• shutdown() -> close all transports
• ConsoleTransport -> default console transport implementation

Environment Variables

• LOG_LEVEL (default: inferred by library, typically INFO)
• SERVICE_NAME (default: noego)
• NODE_ENV (default: development)
