Month: 2024-11 | Repo: githubnext/discovery-agent__facebook__react-native. This month focused on delivering features that enhance performance, image handling fidelity, and UI capabilities, while improving stability and test coverage. Key accomplishments span Android image caching, image rendering options, iOS TextInput improvements, and quality/flow enhancements that reduce noise in CI. Impact and value: - Improved app performance and perceived responsiveness on Android through new image caching controls (only-if-cached, force-cache), reducing redundant network calls and enabling offline-ready behavior where appropriate. - Enhanced image rendering fidelity and flexibility with support for resizeMode 'none' across Fabric and Paper, enabling intrinsic image sizing where needed and preventing unwanted scaling. - Expanded UI customization on iOS by introducing inputAccessoryViewButtonLabel prop for TextInput (Fabric and Paper), enabling better editor and user interactions in RN contexts. - Strengthened development workflow and reliability via internal quality improvements: excluding Pods from Flow checks and bolstering Android image test coverage, leading to more robust builds and faster validation. Top achievements: - Android image caching controls added (only-if-cached, force-cache). - Image component: resizeMode 'none' support across Fabric/Paper. - iOS TextInput: inputAccessoryViewButtonLabel prop added. - RNTester dark mode visibility fix for description text. - Flow/test coverage improvements for Android image tests and Pods exclusion. Selected commits (for traceability): - fix(rn-tester): playground description not visible in dark mode (#47346) — 566d30f88ad8f6fa32d115df2839d4be6c6ff4b1 - feat(image): [android] adding `only-if-cached` cache control option (#47348) — dc9db01665308ac931967326abfc86deb9ae7e2a - feat(image): [android] adding `force-cache` cache control option (#47426) — a0be88fd727898d4626ca51876d0bfb4e50dcb77 - feat(image): support for `resizeMode` and `objectFit` value of `'none'` (#47110) — d8cfd98070cbccc5e8a49446d76bdc2cb0c6939f - feat(text-input): [iOS] `inputAccessoryViewButtonLabel` prop (#47441) — 32931466ed7e3d8d9eeeb65f12ce146e123870ba - fix(rn-tester): pixel ratio example inputs not fully visible in dark mode (#47526) — 998ab262ea758bd513983a4da3b70cef6ec008c2 - fix(image): [android] cache control headers are being overwritten (#47922) — 81cb166d103f7caaa5135b5a1c66d4e978f3619f - fix(flow): excluding `packages/rn-tester/Pods/` from flow checks (#47474) — 8bb3033d73e87f6220e7332c1f4668069e850266 - test(image): [android] adding missing image resize mode test cases (#47527) — 6295b81e79f14a1670e3417e76d569603962ab1e
