Enable the RN Strict TypeScript API

@collectioneur

Problem

RN 0.80 made the Strict TypeScript API opt-in. We are not using it. RN 0.87 enables it by default.

Solution

While we're waiting for Expo SDK 58 to stabilize, let's work on opting-in to the Strict TypeScript API.

Issue Owner

I'm wondering if maybe we should try to land #99495 first. It's proving to be a bear of a PR

Looks like there's a skill specifically for this npx skills add react-native-community/skills --skill migrate-to-strict-api. I'll give it a spin

Bailed out. React Native 0.86 opt-in produced 2944 errors across 420 files, so the Strict API is not enabled.
Kept the dual-compatible rewrites (5 deep imports moved to react-native root exports; NodeHandle and HardwareBackPressEvent inlined). Typecheck passes.
Still blocking a later attempt:

ReactNativeStyleAttributes in src/components/AlwaysPaintedView/index.native.tsx — private, no root export

Removed types: AlertStatic, CellRendererProps, ViewToken, ViewabilityConfig, ImageResizeMode, TextInputPasteEventData

Widespread style/*Instance ref mismatches

react-native-safe-area-context is 5.6.2; Strict API needs >= 5.8.1. Feedback thread: react-native-community/discussions-and-proposals#1015

This isn't technically a blocker for the RN 0.88 bump (we can still explicitly opt out), so I'm making this a weekly

Yes, I can take this on. I'm currently updating the dependencies required to upgrade React Native to 0.88, so I'll start working on it as soon as the required libraries are migrated 🙌

@collectioneur how is this looking?

I looked into migrating the repo to the strict ts API about a week ago, and it seems like quite a big task. Once I wrap up the gesture handler hook migration, I'll get started on it (early next week) 👌

This issue has not been updated in over 15 days. @Julesssss, @mountiny, @roryabraham, @shubham1206agra, @war-in, @jakubstec, @collectioneur eroding to Monthly issue.

P.S. Is everyone reading this sure this is really a near-term priority? Be brave: if you disagree, go ahead and close it out. If someone disagrees, they'll reopen it, and if they don't: one less thing to do!

moving back to weekly. Progress on this will continue once RN 0.88 upgrade is done. RN 0.89 release is scheduled for 2026-12-07, so ideally we should shoot to have this done by then.
