I want to use a node library which relies on stream (require('stream')) within a React Native project.

This is failing with error stream could not be found within the project because stream is a nodejs package not available in React Native.

What can I do ?

I read that allows the use of streams in the browser. But how can I make the require('stream') in the library (that I don't control) require stream-browserify instead.

I had the same problem in my ReactNative project and tried many suggestions, but what finally worked for me was to use the resolver: section in metro.config.js.

My issues were with both stream and crypto.

Here is the resolver section that fixed my problems-

resolver: {
  extraNodeModules: {
      stream: require.resolve('readable-stream'),
      crypto: require.resolve('react-native-crypto-js'),
  }
},

I got the same error too and ended up installing:

1. yarn add stream
2. yarn add events

In my case the issues with dependencies started trying to generate an HMAC with this library: https://github./crypto-browserify/createHmac

I got the same error and I solved it by just installing the stream:

npm install stream

Just had a similar issue. You can install the react native-friendly package stream-browserify as stream with npm install stream@npm:stream-browserify
