Real Strategies To Modernize a Legacy React Native Project
summary
Practical steps and measurable outcomes appear: convert JS to TS by bulk-renaming files, run JSCodeShift codemods to add explicit anys then enable noImplicitAny to complete migration, adopt NX affected flag in a monorepo to run only impacted tests, replace old animation/gesture libs with reanimated and gesture-handler, audit test coverage for real paths, and track velocity and test-run-time improvements (claims of orders-of-magnitude savings for CI are given and concrete config changes are shown).
