feat(analytics): count CV and resume.json downloads server-side - #145
Conversation
The GoatCounter JS beacon only runs on HTML pages, so direct requests for the PDF CVs and the JSON Resume were invisible -- e.g. a CV link opened from a printed CV or an email. A Netlify edge function on those paths now reports each download to the GoatCounter API, reusing the API sender and GOATCOUNTER_API_TOKEN of the /gc/count proxy. GoatCounter's API path skips the bot detection of its /count endpoint, so crawlers, link previews and scripts are filtered by user agent here. Prefetches, HEAD requests, failed responses and a PDF viewer's follow-up byte ranges are not counted either, so one download is one hit. /resume.json is not counted itself: it redirects to /de|en/resume.json, which are. Verified with pnpm check:quick; e2e tests not run.

Bot detection is left to GoatCounter: its API flags hits by the forwarded user agent. Only its IP-range check is skipped on the API path, so bots with browser user agents from datacenter IPs are counted -- an accepted gap rather than duplicating GoatCounter's IP lists. /resume.json is not counted itself: it redirects to /de|en/resume.json, which are.

- Line 27: Update the `context.next()` call in the `count-download` handler to
enable `sendConditionalRequest`, preserving conditional requests such as
`If-None-Match` when forwarding the unmodified response. Update the local
`Context.next` type to accept this option.

context.next() strips If-None-Match/If-Modified-Since by default, so a browser revalidating a cached CV PDF got the full file again instead of a 304. The download counter doesn't transform the body, so it can pass conditional requests through. A 304 is still counted: the visitor opened the file again.

If GOATCOUNTER_API_TOKEN is available to deploy previews or branch deploys, opening a CV there was recorded in the production GoatCounter site. The JS beacon already avoids this by checking the hostname against siteUrl; the download counter now uses the same check, so it doesn't depend on how the token is scoped in Netlify. The tradeoff is that counting can only be verified after merging.

CV PDF and resume.json downloads are now counted server-side, so "which pages are visited" no longer described what is measured. "Content" covers both without listing every counted file in the policy.

The GoatCounter JS beacon only runs on HTML pages, so direct requests for
the PDF CVs and the JSON Resume were invisible -- e.g. a CV link opened
from a printed CV or an email. A Netlify edge function on those paths now
reports each download to the GoatCounter API, reusing the API sender and
GOATCOUNTER_API_TOKEN of the /gc/count proxy.
Unlike the beacon, a file request is not proof of a rendered view:
prefetches, HEAD requests, failed responses and a PDF viewer's follow-up
byte ranges are not counted, so one download is one hit.
Only requests to the production hostname (siteUrl) are counted, like the
JS beacon, so opening a CV on a deploy preview doesn't pollute the
production stats regardless of how the token is scoped in Netlify. The
tradeoff is that counting can only be verified after merging.
Bot detection is left to GoatCounter: its API flags hits by the forwarded
user agent. Only its IP-range check is skipped on the API path, so bots
with browser user agents from datacenter IPs are counted -- an accepted
gap rather than duplicating GoatCounter's IP lists.
Conditional requests are passed through to the CDN, so a browser
revalidating a cached CV gets a 304 instead of the whole file again; the
revalidation still counts, since the visitor opened the file again.
/resume.json is not counted itself: it redirects to /de|en/resume.json,
which are.
The privacy policy now says GoatCounter measures which content is
accessed instead of which pages are visited, since downloads are counted
too.
