Cloudflare Worker that counts plugin marketplace traffic. Deployed on the same Cloudflare account as the dbxio.com site (npx wrangler deploy from this directory; OAuth login required).

Routes

dl.dbxio.com/plugins/* — counts every GET of a real .dbxp artifact (icons and other static assets under the same prefix are excluded: they are fetched on every marketplace page/app view, which both burned KV quota and inflated the numbers), then passes the request through to the R2 custom domain. Artifact bytes, headers, and Range semantics are untouched.
dbxio.com/api/plugins/install — POST fire-and-forget beacon the desktop app can send after a successful marketplace install ({"id": "<plugin id>", "version": "<version>"}, 204 on accept). Decorative statistics only: no auth, no PII.

Storage — Workers Analytics Engine

One datapoint per event (binding PLUGIN_STATS):

blobs = [kind, pluginId, version] where kind is dl (artifact GET) or inst (install beacon); doubles = [1]; indexes = [pluginId].

Chosen over KV counters: KV read-modify-write costs 1 write per request, and the free tier's 1k writes/day is below what a 30k-user base generates on a hot plugin release day (2026-09-15: icon traffic blew the quota within hours). Analytics Engine writes are effectively free at this scale.

Daily aggregation (permanent archive)

AE retains only three months, so a cron trigger (30 0 * * * UTC) aggregates the trailing window into the plugin_stats_archive KV namespace — the permanent layer future UI reads:

total:{kind}:{pluginId}:{version} — all-time cumulative events
summary — one JSON blob {dl: {pluginId: n}, inst: {...}} for single-read display
meta:last-success — window marker; only advanced after all writes land, so a failed run retries the same window on the next cron

Required secret (SQL API access; OAuth login does not carry analytics scope):

echo "<token>" | npx wrangler secret put ANALYTICS_TOKEN

Create the token in the dashboard with Account → Analytics → Read. The same token authorizes the manual trigger (verification / backfill):

curl -s -X POST https://dbxio.com/api/plugins/archive -H "x-archive-token: <token>"

Reading counters

No HTTP stats endpoint (there is no consumer yet; add one when the marketplace UI ships). Query via the SQL REST API with an API token that has Account → Analytics → Read:

curl -s "https://api.cloudflare.com/client/v4/accounts/<account_id>/analytics_engine/sql" \
  -H "Authorization: Bearer <token>" \
  --data-urlencode "query=SELECT blob1 AS kind, blob2 AS plugin, blob3 AS version, SUM(_sample_interval) AS events FROM DBX_PLUGIN_STATS WHERE timestamp > NOW() - INTERVAL '7' DAY GROUP BY 1,2,3 ORDER BY events DESC"

At current volume sampling is 1:1, so SUM(_sample_interval) equals the event count. Counters start from the Analytics Engine migration; the polluted KV-era numbers (plugin_stats namespace) were discarded.
