Using bip39 with React Native about bip39 HOT 9 CLOSED

I also edited the index.js file to before compiling to require 'create-hash/browser' instead of just 'create-hash' to no avail.

I haven't had this issue, are you browserifying in such a way that Buffer is ignored?

from bip39.

I'm browserifying exactly as npm rum compile does it as well as trying browserify index.js -o bip39.js so that it can be required appropriately.

One fix I found was to add this line before requiring bip39, but then I get an assert is not defined error:

global.Buffer = global.Buffer || require('buffer').Buffer;

which suggests to me that I'm going have to do this for every Node.js module I want to use (assert, crypto, stream, etc). I'm currently looking for a more reasonable alternative to this.

Check the resultant file, if the "Buffer" module doesn't exist in there, something is terribly wrong.
What browserify/node/npm version?

from bip39.

node: 0.12.7
npm: 2.11.3
browserify: 12.0.1

If you run browserify index.js -o bip39.js with these settings, at line 365 begins the IIFE defining the Buffer class. assert's definition is the first thing code after the big one-liner from browserify, crypto begins on line 6072, etc.

How are you then using bip39.js?

from bip39.

So as it turns out there are three ways I can use it (the npm run compiled version only), of which only the last method works:

1. bip39.js in the same folder as index.js, and the code I use islet bip39 = require('bip39/bip39'); - get the Buffer is not defined error.
2. bip39.js in the same folder as index.js, and the code is let bip39 = require('../../node_modules/bip39/bip39.js');- same Buffer is not defined error.
3. bip39.js inside my src/, and the code is let bip39 = require('./bip39.js'); - and this works!

I'm almost certain this has something to do with React Packager and not your library, so I really appreciate your help!

require('bip39')

Is all you should need.
If that doesn't work, then something is wrong with you are using react native.

@sunny-g I assume this all worked out in the end?
