Upgrade TanStack DB starter dependencies

[KyleAMathews]

Summary

Upgrade the TanStack DB web and Expo starters to current Electric, TanStack DB, TanStack Start, Expo, React, Drizzle, and supporting dependency versions.

This keeps the starters installable/buildable with current package releases and updates the Expo write-path/proxy code for the newer Electric/TanStack optimistic txid contract.

Approach

• Upgraded dependencies in:
  • examples/tanstack-db-web-starter
  • examples/tanstack-db-expo-starter
• Regenerated pnpm-lock.yaml after rebasing onto latest origin/main.
• Kept generated routeTree.gen.ts out of the diff because it is autogenerated and the build succeeds without committing formatter churn.
• Moved build/type-only packages out of runtime dependencies where appropriate:
  • drizzle-kit remains in web starter devDependencies
  • @types/cors and @types/express moved to Expo starter devDependencies
• Used Expo-compatible fixed/tilde versions for Expo/RN-managed packages and validated with expo-doctor.
• Updated the Expo starter write path to return numeric Electric txids from:

  SELECT pg_current_xact_id()::xid::text AS txid

  after each mutation in the same transaction.
• Updated the Expo Electric proxy to handle missing response bodies before writing response headers.

Key invariants

• Electric optimistic mutations must return a txid that matches Electric’s expected transaction-id handshake.
• Expo SDK-managed dependencies should satisfy expo-doctor.
• The PR diff should only include the two starter apps and the lockfile, not unrelated agent/runtime changes.
• Autogenerated route-tree churn should not be committed.

Non-goals

• No changes to Electric runtime/packages or published package APIs.
• No native Android/iOS build was run; verification covers TypeScript, Expo doctor, and Expo web export.
• No changeset is included because only private examples changed.

Trade-offs

• Expo config fields rejected by expo-doctor were removed rather than preserved in their old locations. This trusts the SDK 56 schema validation over retaining stale config.
• The one Readable.fromWeb compatibility cast remains inline; extracting a helper would add indirection for a single type mismatch.
• TypeScript remains on ^5.9.3 in the web starter to avoid unsupported TS 6 peer ranges in the eslint tooling, while the Expo starter uses Expo’s expected ~6.0.3.

Verification

pnpm --dir packages/typescript-client build
pnpm --dir examples/tanstack-db-expo-starter exec tsc --noEmit
cd examples/tanstack-db-expo-starter && npx expo-doctor
pnpm --dir examples/tanstack-db-expo-starter exec expo export --platform web
pnpm --dir examples/tanstack-db-web-starter build
git diff --check

expo-doctor passes 21/21 checks.

The web starter build still emits this warning, but succeeds:

The plugin "vite-tsconfig-paths" is detected. Vite now supports tsconfig paths resolution natively via the resolve.tsconfigPaths option.

Files changed

• examples/tanstack-db-web-starter/package.json
  • Upgrades web starter dependencies/devDependencies and removes duplicate runtime drizzle-kit.

  • Generates txids after mutations in the same transaction.
  • Fixes Electric proxy empty-body handling order.
• examples/tanstack-db-expo-starter/app/index.tsx
  • Returns typed numeric txids directly from mutation handlers.
