From 3fb9ccce62b457ae7151ccf0041d69be4dbe1564 Mon Sep 17 00:00:00 2001 From: nickllerandi Date: Thu, 8 Jan 2026 14:30:16 -0500 Subject: [PATCH 1/4] Kargo Analytics Adapter: Complete rewrite with full event tracking This commit upgrades the Kargo Analytics Adapter from a minimal implementation to a comprehensive analytics solution. ## Changes ### Module (kargoAnalyticsAdapter.js) - Expanded from 2 events to 9 core Prebid events: - AUCTION_INIT, BID_REQUESTED, BID_RESPONSE, NO_BID - BID_TIMEOUT, BIDDER_DONE, BIDDER_ERROR, AUCTION_END, BID_WON - Now tracks ALL bidders, not just Kargo (competitive intelligence) - Implemented auction cache pattern for state management - Added Kargo-specific metrics: win/loss, margin to win, rank, response times - Privacy consent handling (GDPR, USP, GPP) with sanitized strings - Configurable sampling rate (1-100%) - New POST endpoints: /api/v2/analytics/auction and /api/v2/analytics/win - Graceful error handling throughout ### Tests (kargoAnalyticsAdapter_spec.js) - Comprehensive test suite with 31 test cases covering: - Adapter registration and configuration - All event handlers - Privacy consent extraction - Sampling behavior - Payload formatting - Error handling - Competitive metrics ### Technical Details - Uses established patterns from PubMatic/Magnite adapters - Event handler map for clean event routing - Delayed send to allow BID_WON events before auction data - Automatic cleanup of old auction cache entries gulp lint: PASSED gulp test --file kargoAnalyticsAdapter_spec.js: PASSED (31 tests) --- modules/kargoAnalyticsAdapter.js | 737 ++++++++++++++++-- .../modules/kargoAnalyticsAdapter_spec.js | 572 +++++++++++++- 2 files changed, 1236 insertions(+), 73 deletions(-) diff --git a/modules/kargoAnalyticsAdapter.js b/modules/kargoAnalyticsAdapter.js index 63c452a8791..2d7289ff8d2 100644 --- a/modules/kargoAnalyticsAdapter.js +++ b/modules/kargoAnalyticsAdapter.js @@ -1,96 +1,723 @@ -import { logError } from '../src/utils.js'; +import { logError, logWarn } from '../src/utils.js'; import { ajax } from '../src/ajax.js'; import adapter from '../libraries/analyticsAdapter/AnalyticsAdapter.js'; import adapterManager from '../src/adapterManager.js'; import { EVENTS } from '../src/constants.js'; +import { getGlobal } from '../src/prebidGlobal.js'; -const EVENT_URL = 'https://krk.kargo.com/api/v1/event'; +/// /////////// CONSTANTS ////////////// +const ADAPTER_CODE = 'kargo'; const KARGO_BIDDER_CODE = 'kargo'; +const ANALYTICS_VERSION = '2.0'; +const ENDPOINT_BASE = 'https://krk.kargo.com/api/v2/analytics'; +const SEND_DELAY = 500; // ms delay to allow BID_WON events +const LOG_PREFIX = 'Kargo Analytics: '; +const CURRENCY_USD = 'USD'; -const analyticsType = 'endpoint'; - -let _initOptions = {}; +/// /////////// DEFAULT CONFIG ////////////// +const DEFAULT_CONFIG = { + sampling: 100, // Percentage of auctions to track (1-100) + sendWinEvents: true, // Send individual win events + sendDelay: SEND_DELAY, // Delay before sending auction data (ms) +}; -const _logBidResponseData = { - auctionId: '', - auctionTimeout: 0, - responseTime: 0, +/// /////////// STATE ////////////// +const cache = { + auctions: {}, // Map }; -const _bidResponseDataLogged = []; +let _config = { ...DEFAULT_CONFIG }; +let _sampled = true; // Whether this session is sampled + +/// /////////// HELPER FUNCTIONS ////////////// + +/** + * Determines if current session should be sampled based on config + */ +function shouldSample() { + const samplingRate = _config.sampling || 100; + return Math.random() * 100 < samplingRate; +} + +/** + * Converts CPM to USD using Prebid's currency conversion if available + */ +function convertToUsd(cpm, currency) { + if (!cpm || cpm <= 0) return null; + + if (!currency || currency.toUpperCase() === CURRENCY_USD) { + return parseFloat(Number(cpm).toFixed(3)); + } + + try { + const convertCurrency = getGlobal().convertCurrency; + if (typeof convertCurrency === 'function') { + return parseFloat(Number(convertCurrency(cpm, currency, CURRENCY_USD)).toFixed(3)); + } + } catch (e) { + logWarn(LOG_PREFIX + 'Currency conversion failed:', e); + } + + // Return original CPM if conversion not available + return parseFloat(Number(cpm).toFixed(3)); +} + +/** + * Extracts sizes from mediaTypes object + */ +function extractSizes(mediaTypes) { + if (!mediaTypes) return []; + + const sizes = []; + if (mediaTypes.banner?.sizes) { + sizes.push(...mediaTypes.banner.sizes); + } + if (mediaTypes.video) { + const { playerSize } = mediaTypes.video; + if (playerSize) { + sizes.push(Array.isArray(playerSize[0]) ? playerSize[0] : playerSize); + } + } + return sizes; +} + +/** + * Extracts privacy consent data from bidder request + */ +function extractConsent(bidderRequest) { + if (!bidderRequest) return null; + + const consent = {}; + + // GDPR + if (bidderRequest.gdprConsent) { + consent.gdpr = { + applies: !!bidderRequest.gdprConsent.gdprApplies, + consentString: bidderRequest.gdprConsent.consentString ?
