Description
Step to reproduce:
-
Import "@fioprotocol/fiojs" library into a React Native application.
-
When running - the following error is thrown on app startup:
error: Error: Unable to resolve moduleeventsfromnode_modules/hash-base/node_modules/readable-stream/lib/_stream_readable.js: events could not be found within the project.
Stacktrace:

After performing recommended reset commands:
$ watchman watch-del-all
$ rm -rf node_modules
$ yarn install
$ react-native start
Then restarting application in iOS Simulator
Getting same error:
"error: Error: Unable to resolve module events from node_modules/hash-base/node_modules/readable-stream/lib/_stream_readable.js: events could not be found within the project."
The file listed above exists under node_modules.
I have done some research and found a similar issue reported here for AWS library:
aws-amplify/amplify-js#153
The common root cause are these dependencies:
fiojs has under it's dependencies create-hash and create-hmac:
"dependencies": {
"ajv": "^6.10.2",
"babel-runtime": "6.26.0",
"bigi": "^1.4.2",
"browserify-aes": "^1.2.0",
"bs58": "^4.0.1",
"create-hash": "^1.2.0",
"create-hmac": "^1.1.7",
"ecurve": "^1.0.6",
"long": "^4.0.0",
"randombytes": "^2.1.0",
"text-encoding": "0.7.0"
},
Background: create-hmac and create-hash use a hash-base module. That does a
"var Transform = require('stream').Transform". That was defined in node.js core (NOT a standard JS function, see https://nodejs.org/api/stream.html#stream_new_stream_transform_options)
