React 19, broken peerDependencies, cannot npm i react-strict-dom

[AlexanderOMara]

Describe the issue

In short, you cannot simply install this package because react-native@>=0.75.2 currently points to 0.79.1 which peerDependencies react@^19.0.0, but this package peerDependencies React 18.

Expected behavior

npm i react-strict-dom into an empty directory should Just-Work™.

Steps to reproduce

Node v22.14.0, npm 10.9.2, react-strict-dom 0.0.34.

npm i react-strict-dom

Test case

Additional comments

Can the peerDependencies simply be updated to include React 19, and a new version published?

  "peerDependencies": {
    "react": "^18.2.0 || ^19.1.0",
    "react-dom": "^18.2.0 || ^19.1.0",
    "react-native": ">=0.75.2"
  },

I haven't noticed any issues when forcing it to use React 19 via --legacy-peer-deps. Additionally react-native requires React 19 and Expo SDK 53 with React 19 is fast approaching the end of an ~2 week beta.
