@jamx/logger

@jamx/logger keeps log creation, convenience methods, processing, formatting, and output as separate pieces.

CoreLogger creates structured records, Logger provides a console-like API, processors can adjust records, and transports decide where logs go. Logging is best-effort: processor, formatter, and transport failures do not escape into application code.

Install

pnpm add @jamx/logger

Quick Example

import {
  ConsoleTransport,
  createNamedLogger,
  PrettyFormatter,
  Severity,
} from "@jamx/logger";

const logger = createNamedLogger({
  name: "api",
  minSeverity: Severity.Info,
  transport: new ConsoleTransport(new PrettyFormatter({ colorize: true })),
});

logger.info("Request completed", {
  requestId: "req_123",
  durationMs: 18,
});
