May 2025 (2025-05) – betagouv/reno: Key feature delivered: Iframe Consent Flow Improvements. The update refines the iframe-based consent prompt to display only when the user has not yet responded and switches host origin retrieval to postMessage, enabling dynamic host/consent status based on origin and robust iframe integration with Consentement and Eligibility components. Commits: 049890fec4cd7726f028f6117dcfc2191eb594f3 and 961555a7df8c69d952fa905f12f099f299c94227. Major bugs fixed: corrected premature consent prompts and brittle origin detection, improving cross-origin reliability. Overall impact: smoother user consent journey, better compliance alignment, and more resilient iframe integration. Technologies/skills demonstrated: cross-origin messaging with postMessage, iframe integration, dynamic UI state, integration with Consentement and Eligibility components. Business value: reduces user friction, increases accurate consent capture, lowers risk for origin-based access control.
