All 16 handlers previously mixed two HTTP client styles:
- 7 used Node's built-in https.get()/http.get() with callback events
(data/end/error) and 20+ lines of JSON accumulation
- 4 used modern fetch() but without any timeout — upstream hangs would
pin the Express connection indefinitely
Every upstream request now goes through common/fetch-upstream.js, which
wraps fetch() with an 8s AbortController timeout. Handlers shrink from
~20 lines of request boilerplate to a 5-line try/catch:
try {
const apiRes = await fetchUpstream(url);
const json = await apiRes.json();
res.json(modifyJson(json));
} catch (e) {
res.status(500).json({ error: e.message });
}
Converted handlers:
- ipinfo-io / ipapi-com / ipapi-is / ip2location-io / ip-sb / mac-checker
(dropped `import { get } from 'https'/'http'`, rewrote the request)
- ipcheck-ing / invisibility-test / update-user-achievement / get-user-info
(already on fetch, swapped to fetchUpstream to gain the timeout)
- cf-radar (inline fetchFromCloudflare helper swapped to fetchUpstream)
Special case: google-map.js streams a binary JPEG to the client rather
than parsing JSON. Uses Readable.fromWeb(apiRes.body).pipe(res) to
bridge the fetch ReadableStream to the Express response.
Net -150 lines of handler code; upstream hangs now cap at 8s instead
of 30-120s; consistent error handling across all handlers.
