Fix search-funnel analytics: report to Matomo via _paq + sendBeacon - #13038
Merged
Conversation
…eacon The search-modal and availability-toggle events added in internetarchive#12948 only ever reached Athena (via ol_send_event_ping), which does not forward into Matomo, so they never reported. Matomo normally ingests these via a tag-manager DOM trigger on data-ol-link-track, but that trigger can't see Shadow DOM (the Lit search modal / ol-toggle). Add a trackEvent() helper that pushes straight onto Matomo's _paq queue — the path the trigger ultimately uses — and route SearchModal._track and the SearchFilterBar toggle through it. Enable alwaysUseSendBeacon so events fired right before a navigation survive the page unload.

There was a problem hiding this comment.
Lgtm! Can't really test this ; just confirmed the beacon appearing in the networks panel.

Closes #13020
fix — The search-funnel events added in #12948 emitted but never landed in Matomo.
They were sent through
archive_analytics.ol_send_event_ping, which pings Athena — and Athena doesn't forward events into Matomo (confirmed by @scottbarnes on #13020). Matomo normally ingests OL events via a tag-manager DOM trigger ondata-ol-link-track, but that trigger can't see inside Shadow DOM, where the Lit search modal andol-togglelive. So these controls had no path into Matomo.Technical
trackEvent(category, action, label)helper inol.analytics.jspushes onto Matomo's_paqqueue directly — the same path the DOM trigger uses, so events report regardless of Shadow DOM.SearchModal._track()and theSearchFilterBartoggle route through it; the Athena ping is dropped.head.htmlnow pushes['alwaysUseSendBeacon'], so events that fire right before a navigation (result-click, "see all", toggle) are sent vianavigator.sendBeacon()and survive the page unload.Testing
With a Matomo-enabled environment, spy on the queue in DevTools:
const o = _paq.push.bind(_paq); _paq.push = (...a) => { console.log('PAQ', ...a); return o(...a); };['trackEvent', 'SearchModal', 'Open', 'click'].ResultClick / edition:3; "See all" →SeeAllResults / hasResults; no-results query →NoResults./search, toggle Readable Only →SearchFilter / AvailabilityOn|Off.Screenshot
No UI changes — analytics wiring only.
