MonetaryUnitJS (monetaryunitjs-lib)

The pure JavaScript MonetaryUnit library for node.js and browsers.

Features

• Clean: Pure JavaScript, concise code, easy to read.
• Compatible: Works on Node.js and all modern browsers.
• Powerful: Support for advanced features, such as multi-sig, HD Wallets.
• Secure: Strong random number generation, trusted developers.
• Principled: No support for browsers with crap RNG (IE < 11)
• Standardized: Node community coding style, Browserify, Node's stdlib and Buffers.
• Fast: Optimized code, uses typed arrays instead of byte arrays for performance.
• Experiment-friendly: MonetaryUnit Mainnet and Testnet support.

Should I use this in production?

If you are thinking of using the master branch of this library in production, stop. Master is not stable; it is our development branch, and only tagged releases may be classified as stable.

Installation

npm install monetaryunitjs-lib

Setup

Node.js

var monetaryunit = require('monetaryunitjs-lib')

Browser

If you're familiar with how to use browserify, ignore this and proceed normally. These steps are advisory only, and may not be suitable for your application.

Browserify is assumed to be installed for these steps.

For your project, create an index.js file

let monetaryunit = require('monetaryunitjs-lib')

// your code here
function myFunction () {
	return monetaryunit.ECPair.makeRandom().toWIF()
}

module.exports = {
	myFunction
}

Now, to compile for the browser:

browserify index.js --standalone foo > app.js

You can now put <script src="app.js" /> in your web page, using foo.myFunction to create a new MonetaryUnit private key.

NOTE: If you uglify the javascript, you must exclude the following variable names from being mangled: BigInteger, ECPair, Point. This is because of the function-name-duck-typing used in typeforce.

Example:

uglifyjs ... --mangle --reserved 'BigInteger,ECPair,Point'

NOTE: This library tracks Node LTS features, if you need strict ES5, use --transform babelify in conjunction with your browserify step (using an es2015 preset).

NOTE: If you expect this library to run on an iOS 10 device, ensure that you are using [email protected] or greater.

The below examples are implemented as integration tests, they should be very easy to understand. Otherwise, pull requests are appreciated. Some examples interact (via HTTPS) with a 3rd Party Blockchain Provider (3PBP).
