Public Val Town analytics service:

• https://www.val.town/x/pchinjr/valtown_project_analytics

Live service:

valtown_project_analytics is a reusable analytics service for lightweight event tracking across multiple Val Town projects.

It provides:

• a browser client script you can drop into any Val Town app
• an ingest endpoint for event writes
• simple JSON reporting endpoints for summaries and recent events
• shared storage using Val Town global SQLite

This is intentionally small and pragmatic. It is meant for meaningful product events, not full session replay or enterprise analytics workflows.

• GET / Human-readable landing page with usage notes
• GET /client.js Reusable browser client
• POST /track Event ingest endpoint
• GET /summary?project=<name> Per-project summary with unique sessions, totals, and recent events
• GET /events?project=<name>&limit=25 Recent per-project event stream
• OPTIONS * CORS preflight handling

Events are stored in a shared SQLite table named events.

Columns:

• id
• project
• event
• session_id
• page_path
• page_url
• referrer
• source
• user_agent
• ts
• received_at
• props_json

Indexes:

• idx_events_project_ts
• idx_events_project_event_ts

<script src="https://pchinjr--2dfdceb4239511f1baa142dde27851f2.web.val.run/client.js" defer></script>
<script defer>
  window.addEventListener("DOMContentLoaded", function () {
    const analytics = window.ValTownAnalytics.init({
      project: "my-project",
      globalProps: {
        app: "my-project",
      },
    });

    analytics.track("page_viewed", { screen: "landing" });
  });
</script>

window.ValTownAnalytics.init(config) accepts:

• project
• endpoint optional override
• globalProps optional object merged into every event
• debug optional boolean

It returns:

• track(event, props)
• sessionId()

Behavior:

• generates and persists a browser session id in localStorage
• uses navigator.sendBeacon when available
• falls back to fetch with keepalive

Good fit for:

• custom event analytics across several Val Town projects
• product funnels and lightweight reporting
• simple owner-controlled instrumentation

Not designed for:

• session replay
• identity stitching across devices
• advanced cohort analysis
• enterprise-scale analytics workloads

• main.ts Full analytics service implementation
