January 2025 performance highlights for coopcycle-web. Focused on delivering business-value features, stabilizing critical data flows, and expanding test coverage. Key backend and integration work includes endpoints to manage store addresses, beta form integration with legacy preservation, and significant pricing/serialization enhancements for deliveries. Additional improvements include injecting and scoping the HTTP client in beta form, multi-drop delivery support, and UI/data-model refinements such as streetAddress in list view and ShowPrice refactor. Expanded testing across address endpoints, Cypress beta-form tests, and Behat adjustments reduced regressions and improved confidence for next release.

December 2024 focused on delivering business value through improved distance and CO2 emission calculations for unassigned deliveries, stronger data integrity for pricing, and improved task management and delivery APIs/UI. Key outcomes include: 1) distance and emissions accuracy for deliveries without a vehicle, with tests and change-set stability; 2) store-specific package pricing with a new repository method to fetch by name/store and a unique constraint on package names within a set; 3) centralization of task list fetching via a dedicated TaskListProvider to reduce duplication and improve maintainability; 4) code quality improvements through a nullsafe refactor of Task.getStore for better readability; 5) API/UI enhancements for deliveries, including JSON-LD usage, token-based store resolution, and UI data integrity improvements, plus targeted rider-filter fixes to ensure hidden riders/tasks are respected.
