💡 Result:

Yes, in Nitro/Hookable, hooks.callHook(...) returns a Promise that should be awaited or otherwise handled to avoid unhandled rejections if any hook callbacks reject.

Does @opentelemetry/exporter-prometheus start a standalone Node.js HTTP server, and is that supported in edge/serverless runtimes like Cloudflare Workers or Vercel?

💡 Result:

Yes, @opentelemetry/exporter-prometheus starts a standalone Node.js HTTP server by default on port 9464 to expose metrics for Prometheus scraping, as shown in official documentation and examples where instantiation with { port: 9464 } enables access at http://localhost:9464/metrics. This can be prevented using the preventServerStart: true option, allowing manual control via exporter.getMetricsRequestHandler(req, res) to integrate into an existing server. However, it is not supported in edge/serverless runtimes like Cloudflare Workers or Vercel Edge Functions. Cloudflare Workers (V8 isolates) fail to import due to Node.js "http" module dependencies, even with preventServerStart: true and node_compat=true (errors: "Could not resolve 'http'", "globalThis.XMLHttpRequest is not a constructor"). Vercel documentation focuses on tracing (OTLP), with no Prometheus exporter mention; Edge runtime custom spans unsupported. Use OTLP/HTTP exporters or platform-native observability instead.

H3 H3Event event.req.url relative path absolute pathname

💡 Result:

In H3 (the high-performance HTTP framework used by Nuxt/Nitro), an H3Event object is created for each incoming HTTP request. The event.req property provides access to the incoming HTTP request information, modeled after the native Web API Request with runtime addons. event.req.url is a string containing the absolute URL of the request (full URL including protocol, host, port, pathname, search, and hash if present). This matches the standard behavior of the Fetch API's Request.url property, which always returns the absolute URL. However, in server environments like Node.js, H3 constructs event.req such that event.req.url typically holds the relative path (pathname + search) from the request URL, without the origin (e.g., "/api/users?id=123" for a request to "https://example.com/api/users?id=123"). This is consistent with traditional Node.js http.IncomingMessage.url and common server framework conventions, allowing logging like [GET] /api/users. To get the relative path (just pathname + search): - Use event.req.url directly (e.g., "/api/users?id=123") - Or prefer event.path, which is explicitly the request path (same value, recommended over parsing event.req.url) To get the absolute pathname (full URL as string): - Use getRequestURL(event) utility (e.g., "https://example.com/api/users?id=123") Examples from official docs: app.get("/", async (event) => { console.log(event.req.url); // "/" const fullUrl = getRequestURL(event); // "https://example.com/" }); event.path // "/test?test=123" (relative path example) event.url provides a parsed URL object for the full request URL. Sources confirm event.req is Web Request-based but adapted for server use, with event.path preferred for relative paths post-refactors.
