Logs SDK

Package: @mydle/logs. Use only on servers and workers — not in browsers.

import { createMydleLogger } from "@mydle/logs";

const logger = createMydleLogger({
  apiKey: process.env.MYDLE_API_KEY!, // or sourceToken: "lt_…"
  service: "api",
  environment: "production",
});

logger.info("Application started");
logger.warn("Something looks wrong");
logger.error(error);
await logger.flush();
await logger.close();

• trace / debug / info / warn / error / fatal — level helpers.
• log(event) — full event with explicit level.
• flush() — drain the queue; resolves after send success or definitive failure.
• close() — flush, stop accepting events, clear timers.

• apiKey or sourceToken — required credential.
• endpoint — absolute HTTP(S) ingest URL. Default: product host …/api/logs/v1/ingest. Relative paths are rejected by the SDK.
• service, environment, release — defaults applied to events.
• Queue overflow policy: drop_oldest only.

Pass traceId, spanId, sessionId, and requestId on context when you have them. The SDK can also attach active OpenTelemetry traceId / spanId when @opentelemetry/api has a valid span — explicit fields win. No IDs are invented when context is empty.
