Elysia

Import from @blyp/core/elysia.

import { Elysia } from "elysia";
import { createLogger } from "@blyp/core/elysia";

const app = new Elysia()
  .use(createLogger({
    level: "debug",
    customProps: (ctx) => ({
      framework: "elysia",
      path: ctx.path,
    }),
  }))
  .get("/hello", ({ log }) => {
    log.info("elysia-route");
    return "ok";
  });

How it works

What auto-logged requests look like

With automatic request logging enabled, Blyp emits terminal output like:

[INFO]  GET  /health        200  2ms
[INFO]  POST /checkout      200  143ms
[INFO]  GET  /users/42      404  8ms
[ERROR] POST /payments      500  1203ms

Fields included automatically: method, path, status code, and duration.

In production (NDJSON):

{"level":"info","time":1710000000000,"msg":"GET /health","type":"http_request","method":"GET","url":"/health","statusCode":200,"responseTime":2}
{"level":"info","time":1710000000001,"msg":"POST /checkout","type":"http_request","method":"POST","url":"/checkout","statusCode":200,"responseTime":143}
