npm install errorcore

Initialize Errorcore before creating servers, clients, queues, or workers.

import http from "node:http";
import { captureError, flush, init, wrapHandler } from "errorcore";

init({
  service: process.env.ERRORCORE_SERVICE_NAME,
  deploymentEnv: process.env.ERRORCORE_ENVIRONMENT,
  transport: {
    type: "http",
    url: process.env.ERRORCORE_INGEST_URL ?? "https://api-production-7ecf.up.railway.app/v1/ingest",
    apiKey: process.env.ERRORCORE_API_KEY,
  },
  encryptionKey: process.env.ERRORCORE_DEK,
});

async function handler(request, response) {
  const path = new URL(request.url ?? "/", "http://application.local").pathname;
  if (request.method === "GET" && path === "/errorcore-test") {
    captureError(new Error("errorcore test error"));
    await flush();
    response.writeHead(202, { "content-type": "application/json" });
    response.end(JSON.stringify({ sent: true }));
    return;
  }

  // Handle the rest of your application routes here.
}

const server = http.createServer(wrapHandler(handler));

wrapHandler() attaches request context to captures. Call captureError(error) wherever your service intentionally handles an error instead of letting it reach the SDK's process-level handlers.
