@youneed/server-middleware-request-logger

Per-request access logging. Emits METHOD url status durationms [requestId] for every request — including ones that end in an error.

import { Application } from "@youneed/server";
import { requestLogger } from "@youneed/server-middleware-request-logger";

Application()
  .use(requestLogger())
  .listen(3000, () => {});

Structured logging

Pass a @youneed/logger Logger to emit one structured record per request instead of a formatted string:

import { Application } from "@youneed/server";
import { requestLogger } from "@youneed/server-middleware-request-logger";
import { createLogger } from "@youneed/logger";

Application()
  .use(requestLogger({ logger: createLogger({ level: "info", base: { service: "api" } }) }))
  .listen(3000, () => {});

Each request emits logger.info("request", { method, url, status, ms, requestId, traceId? }). The record correlates the requestId (and traceId, read from ctx.state.span when a trace middleware ran earlier — omitted for the all-zero id), and inherits the logger's secret redaction, so authorization / cookie / token etc. never leak. Status drives the level: 5xx and thrown errors → error (with the caught err), 4xx → warn, everything else → info.
