Month: 2026-01 Performance-focused delivery across Expensify/App and callstack-internal/Expensify-App. Key features delivered: - All Transactions collection integration: introduced allTransactionsCollection, restructured props, updated usages, and renamed to allTransactions after Onyx.connect removal for COLLECTION.TRANSACTION, improving data flow and reducing coupling to Onyx.connect. - Modular UI: separated AddUnreportedExpenseFooter into its own component to improve testability and reuse. - Asset and UI performance: added Expensicons assets; implemented Footer performance optimization; included mobile Expensing adjustments. - Data/API modernization: migrated to Onyx data helpers (getOnyxValue/getOnyxData); introduced recentWaypointCollection support; migrated codebase toward Split.ts usage. - Quality and refactors: code formatting with Prettier; Onyx.connect refinements for policies; dependency and mobile-related adjustments; tests and test structure improvements. Major bugs fixed: - Offline playback on cached videos fixed. - Safer sourceURL reset implemented. - Not showing error icon when an error occurs. - Test and lint hygiene: fixes for dismissDuplicateTransactionViolation tests, lint rules, spell checks, imports, and test restructuring. - API/test alignment: Onyx.connect migrated to getOnyxValue where appropriate; unified Onyx data retrieval with getOnyxData; revert/max-warnings adjustments handled. Overall impact and accomplishments: - Improved reliability of transaction rendering and UI responsiveness; stronger test coverage; higher code quality; better resilience to Onyx API changes; enhanced mobile support and asset management; smoother deployment with fewer regressions. Technologies/skills demonstrated: - React/TypeScript, Onyx data layer usage (getOnyxValue, getOnyxData), Split.ts migration, Prettier formatting, linting and testing (functional/QA/unit), code refactors, and performance optimization.
