SQLiteEventRepository

Access the event storage directly:

import { SQLiteEventRepository } from '@opencommerceprotocol/analytics';

const repo = new SQLiteEventRepository('./analytics.db');

// Query stats
const summary = await repo.getMerchantStats('https://mystore.com', '7d');
const tools = await repo.getToolStats('https://mystore.com', '30d');
const timeline = await repo.getTimeline('https://mystore.com', 'day', 30);

Authentication Middleware

import { apiKeyAuth } from '@opencommerceprotocol/analytics';
import { Hono } from 'hono';

const app = new Hono();
// Protect specific routes
app.use('/admin/*', apiKeyAuth());

Set API keys via OCP_ANALYTICS_API_KEYS environment variable (comma-separated).

Event Types

Event Type	When Triggered
tool_call	An OCP tool was called
runtime_init	OCP runtime initialized on a page
widget_open	Chat widget opened by user
widget_message	Message sent in chat widget
llm_tier_used	Browser LLM or cloud LLM used
checkout_started	begin_checkout tool called

OCPAnalyticsEvent

interface OCPAnalyticsEvent {
  type: OCPEventType;       // event type
  timestamp: string;        // ISO 8601
  merchant_url: string;     // identifies the store
  tool?: string;            // tool name for tool_call events
  duration_ms?: number;     // tool call duration
  success?: boolean;        // tool call result
  tier?: ProcessingTier;    // 'regex' | 'browser_llm' | 'cloud_llm'
  session_id?: string;      // anonymized session (no PII)
  metadata?: Record<string, unknown>;  // additional context
}

Client-Side Collection

The analytics client is built into @opencommerceprotocol/runtime. Enable it in OCP.init():

OCP.init({
  handlers: { ... },
  analytics: {
    enabled: true,
    endpoint: 'https://analytics.mystore.com/v1/events',
    flushInterval: 5000,
    storageKey: 'ocp_events',
  },
});

Or import the collector directly:

import { OCPAnalytics } from '@opencommerceprotocol/analytics/client';

const analytics = new OCPAnalytics({
  enabled: true,
  endpoint: 'https://analytics.mystore.com/v1/events',
});

analytics.trackToolCall('search_products', { query: 'headphones' });

Self-Hosting

The analytics server is a standalone Hono application that can be deployed as:

• Node.js: node dist/index.js
• Cloudflare Workers: wrangler deploy (adapt to use D1 instead of SQLite)
• Docker: Mount the SQLite file as a volume
