isomorphic-webcrypto not resolved correctly with react-native expo

[aurmartin]

Describe the bug
The random module does not work with react-native expo.

I have followed the instructions in the README.md (installed isomorphic-webcrypto and enabled unstable_enablePackageExports).

The isomorphic-webcrypto module isn't resolved correctly.

Error message: TypeError: Cannot read property 'ensureSecure' of undefined, js engine: hermes

Stacktrace:

To Reproduce

1. npx create-expo-app@latest
2. Import import * as random from 'lib0/random' and use random.rand()
3. npx expo start
4. Open on android emulator

Expected behavior
Lib0 random module works with react-native expo.

Environment Information

• Expo: 51.0.28
• Lib0: 0.2.98

Additional context
A workaround I have found is to hack the metro resolver:

// Learn more https://docs.expo.io/guides/customizing-metro
const { getDefaultConfig } = require("expo/metro-config");

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

console.warn("THERE")

const config = defaultConfig;

config.resolver.unstable_enablePackageExports = true;

config.resolver.resolveRequest = (context, moduleName, platform) => {
  if (platform !== "web" && moduleName === "isomorphic-webcrypto") {
    return {
      filePath:
        __dirname + "/node_modules/isomorphic-webcrypto/src/react-native.js",
      type: "sourceFile",
    };
  }

  return context.resolveRequest(context, moduleName, platform);
};

module.exports = config;
