ARDA Analytics — Browser Events & GTM Integration

Architecture and Implementation

The central AnalyticsService coordinates smaller modules for UTM parameters, form fields, GTM event pushes, and user journey tracking. This separation gives each concern a defined place in the code while keeping an integration entry point for the application using the plugin.

• Campaign attribution captures UTM values and makes them available to form workflows.

• Form helpers detect and add attribution fields, with a MutationObserver option for dynamically inserted forms.

• Event forwarding writes a CustomEvent object and eventLabel to the GTM data layer.

• Journey triggers run callbacks when configured event combinations occur, with options for one-time execution.

Validation and Integration Boundaries

The repository contains Jest tests for initialization, configuration changes, event pushes, click and form handling, and cleanup. These definitions document intended behavior; their presence alone does not establish that a particular release passes every test. A site adopting the plugin still needs to verify its own events, GTM configuration, and reporting destination.

The plugin forwards browser events; it does not replace an analytics reporting platform. Data collection and consent choices also belong to the integrating site. Performance and data quality should be measured in that site’s actual environment rather than inferred from the plugin’s architecture.

What This Project Demonstrates

Browser API integration, modular TypeScript services, event-driven behavior, and a React interface for exploring developer-facing functionality. It connects frontend implementation with the practical needs of analytics integration.
