Doesn't work?

error: bundling failed: “Unable to resolve module buffer from D:\\ProjectABC\\node_modules\\safe-buffer\\index.js: Module does not exist in the module map\n\nThis might be related to https://github.com/facebook/react-native/issues/4968\nTo resolve try the following:\n 1. Clear watchman watches: watchman watch-del-all.\n 2. Delete the node_modules folder: rm -rf node_modules && npm install.\n 3. Reset packager cache: rm -fr $TMPDIR/react-* or npm start -- --reset-cache.”

Used it like the example using require, and even tried import - same result. Also installing the module ‘buffer’ seperately doesnt help anything. I guess it’s deprecated?

I had same problem and npm i buffer solved my issue. https://github.com/bartonhammond/snowflake/issues/98

So I just had this issue and have been looking into it - it looks like this module breaks because it requires the “randombytes” module, which requires “safe-buffer”, which in turn requires “buffer”. “Buffer” is a Node standard library api, meaning that it ships by default with an installation of Node. Problem is, Node standard library modules are largely written in C++ like the rest of Node, and are not written in Javascript like most NPM modules. Since React Native has no capability for running C++ code, “buffer” doesn’t work, and hence neither does this package.

As far as I can tell, @eugenehp can fix this issue by removing randombytes from the implementation, swapping it out with a module that performs the same function but is written specifically for React Native. I haven’t checked, but this one might work:
