ts split

[chrisnojima]

Summary

Replaces the single shared/tsconfig.json with per-platform configs so that dom APIs are forbidden in native code and native-only APIs are forbidden in desktop code.

• tsconfig.base.json — platform-agnostic compiler options (strict, noEmit, etc.)
• tsconfig.desktop.json — adds dom lib + webpack-env types, excludes *.native.* / *.android.* / *.ios.* files
• tsconfig.native.json — no dom, excludes *.desktop.* and the entire ./desktop/ directory
• tsconfig.json — now just { "extends": "./tsconfig.desktop.json" } as editor fallback
• tools/gen-ts-paths.mjs — scans shared/ for platform-split modules (files with .desktop.tsx/.native.tsx but no plain .tsx) and writes tsconfig.paths.desktop.json + tsconfig.paths.native.json so @/foo imports resolve to the right platform file
• yarn tsc — now regenerates paths then checks both platform configs; both pass at 0 errors

Also fixes ~15 source files where native-specific type errors were surfaced by the stricter native config (DOM globals used in shared/native files, Timeout vs number, ResizeObserver in a .native.tsx, etc.).

and then

Summary

Replaces the generated per-file tsconfig.paths.*.json mappings with TypeScript's built-in moduleSuffixes option, and splits the
single tsconfig.json into proper per-platform configs.

Before: yarn tsc ran a gen-ts-paths.mjs script that scanned for .desktop.tsx/.native.tsx files and emitted ~160 explicit @/foo →
./foo.desktop path mappings. Any platform-split module not in that list resolved to an untyped .d.ts stub (covered by
skipLibCheck).

After: yarn tsc runs tsgo directly against two configs. TypeScript's moduleSuffixes handles suffix resolution automatically —
import from '@/foo' tries foo.desktop.tsx before foo.tsx on desktop, and foo.native.tsx before foo.tsx on native. No generated
files, no stubs.

Source fixes (307 files, ~1700 insertions / ~1250 deletions)

.d.ts stub replacement: ~25 .d.ts stubs that previously bridged cross-platform type gaps were replaced with proper .shared.tsx
barrel files that re-export types explicitly. Platform .desktop.tsx/.native.tsx files that imported from the stub path were
updated to import from .shared.

Circular import fixes: With moduleSuffixes, import from './foo' in foo.native.tsx resolves to itself. Fixed by changing to import
from './foo.shared' in affected .native.tsx files.

Explicit suffix import fixes: import from '@/router-v2/screen-layout.desktop' in a shared file causes the native compiler to look
for screen-layout.desktop.native.tsx, then fall back to the desktop file. Fixed by dropping the explicit suffix and letting
moduleSuffixes resolve.

Native type strictness fixes: The native config has no dom lib. Surfaced issues fixed:

• window.console.log → console.log directly in local-debug.native.tsx
• window.requestIdleCallback narrowing in util/idle-callback.tsx (IIFE approach)
• ScrollViewRef via useImperativeHandle in common-adapters/scroll-view.native.tsx
• File/DataTransfer interface stubs in globals.native.d.ts
• process['type'] bracket notation for noPropertyAccessFromIndexSignature

Platform constant widening: With moduleSuffixes, ESLint now resolves isMobile, isDarwin, isElectron, etc. to their
platform-specific literal values, triggering no-unnecessary-condition in shared files. Fixed by annotating constants as : boolean
/ : string rather than letting them infer as literal types.

Promise/async fixes in desktop files: Properly resolved types exposed floating promises in .desktop.tsx event handlers. Fixed
with void expression pattern.
