## Setup
### Node.js
``` javascript
const bitcoin = require('bitcoinjs-lib')
```
## Usage
### 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](https://github.com/substack/node-browserify) is assumed to be installed for these steps.
For your project, create an `index.js` file
``` javascript
let bitcoin = require('bitcoinjs-lib')
// your code here
function myFunction () {
return bitcoin.ECPair.makeRandom().toWIF()
}
module.exports = {
myFunction
}
```
Now, to compile for the browser:
``` bash
browserify index.js --standalone foo > app.js
```
The recommended method of using `bitcoinjs-lib` in your browser is through [Browserify](https://github.com/substack/node-browserify).
If you're familiar with how to use browserify, ignore this and carry on, otherwise, it is recommended to read the tutorial at http://browserify.org/.
You can now put `<script src="app.js" />` in your web page, using `foo.myFunction` to create a new Bitcoin 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](https://github.com/dcousens/typeforce).
**NOTE**: This library tracks Node LTS features, if you need strict ES5, use [`--transform babelify`](https://github.com/babel/babelify) in conjunction with your `browserify` step (using an [`es2015`](http://babeljs.io/docs/plugins/preset-es2015/) preset).

**NOTE**: If you expect this library to run on an iOS 10 device, ensure that you are using [buffer@5.0.5](https://github.com/feross/buffer/pull/155) or greater.
### Typescript or VSCode users
Type declarations for Typescript are available for version `^3.0.0` of the library.
Type declarations for Typescript [are available](https://github.com/DefinitelyTyped/DefinitelyTyped/tree/0897921174860ec3d5318992d2323b3ae8100a68/types/bitcoinjs-lib) for version `^3.0.0` of the library.
``` bash
npm install @types/bitcoinjs-lib
```
You can now use `bitcoinjs-lib` as a typescript compliant library.
For VSCode (and other editors), users are advised to install the type declarations, as Intellisense uses that information to help you code (autocompletion, static analysis).
