Investigate the possibility of having Realm Web work in React Native

[tomduncalf]

As per https://github.com/realm/realm-js/issues/4174, trying to use Realm Web inside a React Native app throws an error: Can't find variable: TextDecoder. Adding https://www.npmjs.com/package/react-native-polyfill-globals gets further, but we then hit an error {{ WARN Invalid responseType: blob}}.

If it is possible to make Realm Web work inside React Native, this could be beneficial for users who would like to create a React Native app using Realm which also targets web (see https://github.com/realm/realm-js/issues/4177), if offline/sync support is not important (they would need to use Realm Web instead of RealmJS).

I got similar error

import { ApolloClient, HttpLink, InMemoryCache } from "@apollo/client"; import * as Realm from "realm-web";

I am using above 2 realm features to call realm Graphql API in react native Initially I got Error: While trying to resolve module @apollo/client. I added 'cjs' in metro config sourceexts. Now I am getting below error - . I assume the issue is with realm-web. Can you assist to resolve this issue. ReferenceError: Property 'TextDecoder' doesn't exist, js engine: hermes ERROR Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication). A frequent cause of the error is that the application entry file path is incorrect. This can also happen when the JS bundle is corrupt or there is an early initialization error when loading React Native., js engine: hermes

To solve the problem, install the "text-encoding-polyfill" and add the import statement "import 'text-encoding-polyfill'" to your index.js file as early as possible in your app. At least this worked for me, I hope it helps.
