Conversation
- Dev env: react-native 0.87 / react 19.2 / @react-native/jest-preset, TypeScript 5.9 with bundler moduleResolution - ESLint 9 flat config (typescript-eslint, react, react-hooks, prettier); legacy .eslintrc and plugin set removed - react-native-builder-bob 0.43: ESM-enabled commonjs+module targets, dual d.ts output, spec-correct exports map (import/require .types) - @testing-library/react-native v14 (universal test renderer): tests migrated to async render/renderHook, jest pinned to 29 for RN preset - peerDependencies widened: react >=18, react-native >=0.74 (new arch) - CI on Node 22 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Rust-based linting/formatting: oxlint (typescript/react/jest/import plugins, correctness=error) and oxfmt. Removes the eslint 9 flat config, prettier, and the chalk/ora terminal wrapper scripts; lint-staged and CI updated (format:ci replaces prettier:ci). Also: restore top-level types field (node10-resolution consumers ignore the exports map and would otherwise get no types) and revert the CI node-version pin back to lts/*.

Toolchain overhaul so the top-30 library fleet can rebuild on this starter. RN 0.87/React 19 dev env, ESLint 9 flat config, bob 0.43 with ESM + dual d.ts exports, RNTL v14 async tests, peers widened to react>=18 / react-native>=0.74. Verified: build + typecheck + lint + 24/24 tests green.
