If in doubt, see the [.travis.yml](.travis.yml) for what versions are used by our continuous integration tests.

**WARNING**: We presently don't provide any tooling to verify that the release on `npm` matches GitHub. As such, you should verify anything downloaded by `npm` against your own verified copy.
## 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.
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/.
[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
```
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).
Example:
``` bash
uglifyjs ... --mangle reserved=['BigInteger','ECPair','Point']
```
**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), it is advised to install the type declarations, as Intellisense uses that information to help you code (autocompletion, static analysis).
