New Issue Checklist

• I am not disclosing a vulnerability.
• I am not just asking a question.
• I have searched through existing issues.
• I can reproduce the issue with the latest versions of Parse Server and the Parse JS SDK.

Issue Description

On react-native with expo - build , the launch/build fails with the following error
if you add events and stream, you get http and https error too

Android Bundling failed 612ms node_modules/expo-router/entry.js (1315 modules)
The package at "node_modules/parse/node_modules/ws/lib/stream.js" attempted to import the Node standard library module "stream".
It failed because the native React runtime does not include the Node standard library.

Steps to reproduce

Create a react native app using

• npx create-expo-app@latest
• npm i parse#
• const Parse = require('parse/react-native.js');
• npx expo run:android
• run the app on emulator or mobile

Actual Outcome

App should build

found a probable workaround from the expo team

https://docs.expo.dev/versions/latest/config/metro/#packagejsonexports

const { getDefaultConfig } = require('expo/metro-config');

/** @type {import('expo/metro-config').MetroConfig} */
const config = getDefaultConfig(__dirname);

config.resolver.unstable_enablePackageExports = false;

module.exports = config;

i will test to see if this has an impact on Parse, but it seems to take away the error. This issue might be related to ws required by Parse

[lawrenehi]

not related but this error should be in the documentation for latest react-native

https://github.com/uuidjs/uuid?tab=readme-ov-file#getrandomvalues-not-supported

Basically ws is not used in react-native but it didn't get cleaned up (tree-shaking) when the build was output.

This is working

[tiavina-mika]

For Parse SDK < 6.x:
This config.resolver.unstable_enablePackageExports = false; workaround works.

For 7.x:
The following fixes the issue:

npx expo install expo-crypto  
npm install react-native-get-random-values

And add this at the very top of your entry file (e.g. app/_layout.tsx):

import 'react-native-get-random-values';

For 8.x:
None of the above workarounds are effective. The SDK now directly uses Node’s crypto.randomUUID() in lib/react-native/uuid.js, which is incompatible with Expo’s runtime (see error in #2856). A proper React Native–compatible UUID fallback is needed.
