Analytics.js
Acest proiect este o bibliotecă JavaScript de integrare pentru analytics și un colector de evenimente client-side, conceput pentru a înregistra comportamentul utilizatorilor și a distribui acele date către multiple destinații terțe printr-o interfață unificată. Funcționează ca o platformă de date despre clienți (CDP) care identifică utilizatorii, gestionează atributele și direcționează fluxurile de evenimente către diverse instrumente de analiză și depozite de date (data warehouses).
Biblioteca se distinge printr-un router de evenimente multi-destinație și middleware de tracking HTTP care interceptează și modifică payload-urile evenimentelor înainte de transmisie. Implementează primitive de gestionare a identității pentru identificarea utilizatorilor, alierea identităților pentru combinarea profilurilor și tracking cross-subdomain prin stocarea identificatorilor pe domeniul principal.
Sistemul acoperă o gamă largă de capabilități, inclusiv monitorizarea interacțiunii utilizatorilor pentru vizualizări de pagini, trimiteri de formulare și click-uri pe link-uri, precum și tracking-ul campaniilor de marketing prin extragerea parametrilor UTM. Pentru fiabilitate, utilizează batching-ul cererilor de evenimente, cozi de retry bazate pe stocarea locală cu backoff exponențial și flag-uri de tip keepalive în browser pentru a asigura capturarea datelor în timpul redirecționărilor de pagină.
Biblioteca suportă, de asemenea, pixeli de tracking pentru medii care restricționează execuția JavaScript și oferă mecanisme pentru mascarea URL-urilor de integrare, prevenind astfel blocarea cererilor.
Features
- Multi-Destination Data Routing - Implements a unified interface to route collected customer data to multiple third-party analytics destinations simultaneously.
- Multi-Destination Event Routing - Routes a single stream of event data to multiple external analytics destinations through a unified interface.
- Page View Tracking - Records page visits and allows the attachment of custom categories and properties to describe the view.
- Behavioral Data Collection - Collects behavioral user interaction events from digital interfaces for distribution to analytics tools.
- Customer Data Management - Identifies unique users and associates them with specific traits and historical identities across sessions.
- Customer Data Platforms - Functions as a customer data platform for gathering user signals and creating a unified behavioral view.
- Third-Party Data Connectors - Provides connectors to import user and event data from cloud applications for distribution to analytics tools.
- User Identification - Links users and their actions to a unique ID and a set of descriptive traits.
- Event Tracking APIs - Provides a tracking API that enables analytics event transmission from any environment capable of making HTTP requests.
- Event Middleware Systems - Uses a sequence of middleware functions to intercept and modify event data before dispatching it to destinations.
- Stream Event Interception - Employs middleware to intercept, modify, or drop event payloads before they reach their final destinations.
- Behavioral Event Collectors - Provides a browser-based tool for recording page views, form submissions, and link clicks.
- User Interaction Event Logging - Logs specific user actions and includes optional properties to provide context for behavioral analysis.
- User Interaction Recording - Logs specific user actions like form submissions and link clicks for behavioral analytics.
- Analytics Integration Libraries - Provides a JavaScript library for collecting user behavior and distributing event data to multiple analytics destinations.
- Cross-Subdomain Identity Tracking - Tracks unique users across subdomains by storing anonymous identifiers on the top-level domain.
- Web Analytics Integrations - Integrates web applications with analytics services to track user behavior and page views.
- Reverse ETL - Synchronizes processed data from cloud warehouses back into operational marketing and analytics tools.
- Marketing Analytics - Tracks marketing campaign effectiveness by extracting UTM parameters from URLs and recording page views.
- Link Interaction Tracking - Logs clicks on hyperlinks and delays page navigation to ensure analytics data is transmitted.
- Integration Filtering - Provides the ability to enable or disable specific third-party tool integrations for individual event calls.
- Fetch Keepalive Deliveries - Utilizes the browser fetch keepalive flag to ensure analytics data delivery during page unloads and redirects.
- Cross-Subdomain Session Sharing - Maintains consistent user identity across subdomains by storing anonymous IDs on the top-level domain.
- Identity Aliasing - Combines separate user identities into a single profile to maintain a consistent behavioral history.
- Request Batching - Groups multiple individual event calls into a single HTTP request to reduce network overhead.
- Client-Side Persistence - Implements a local storage-based retry queue with exponential backoff to prevent data loss during network outages.
- Submission Tracking - Binds tracking calls to form submissions and delays redirection until the event is successfully delivered.
- Async Request Completion - Uses the browser keepalive flag to guarantee analytics data transmission completes during hard page redirects.
- Persistent Retry Queues - Persists failed network requests in the browser's local storage and attempts redelivery with exponential backoff.
- UTM Parameter Parsing - Automatically reads marketing campaign data from URL query strings and attaches it to event payloads.
- HTTP Middleware Pipelines - Implements a middleware pipeline to modify event payloads and add custom headers before API transmission.
