# Ethereum JavaScript API
This is the Ethereum compatible JavaScript API using `Promise`s
which implements the [Generic JSON RPC](https://github.com/ethereum/wiki/wiki/Generic-JSON-RPC) spec. It's available on npm as a node module and also for bower and component as an embeddable js
[![NPM version][npm-image]][npm-url] [![Build Status][travis-image]][travis-url] [![dependency status][dep-image]][dep-url] [![dev dependency status][dep-dev-image]][dep-dev-url]
<!-- [![browser support](https://ci.testling.com/ethereum/ethereum.js.png)](https://ci.testling.com/ethereum/ethereum.js) -->
## Installation
### Node.js
npm install ethereum.js
### For browser
Bower
bower install ethereum.js
Component
component install ethereum/ethereum.js
* Include `ethereum.min.js` in your html file.
* Include [es6-promise](https://github.com/jakearchibald/es6-promise) or another ES6-Shim if your browser doesn't support ECMAScript 6.
## Usage
Require the library:
var web3 = require('web3');
Set a provider (QtProvider, WebSocketProvider, HttpRpcProvider)
var web3.setProvider(new web3.providers.WebSocketProvider('ws://localhost:40404/eth'));
There you go, now you can use it:
```
web3.eth.coinbase.then(function(result){
console.log(result);
return web3.eth.balanceAt(result);
}).then(function(balance){
console.log(web3.toDecimal(balance));
}).catch(function(err){
console.log(err);
});
```
For another example see `example/index.html`.
## Building
* `gulp build`
### Testing
**Please note this repo is in it's early stage.**
If you'd like to run a WebSocket ethereum node check out
[go-ethereum](https://github.com/ethereum/go-ethereum).
To install ethereum and spawn a node:
```
go get github.com/ethereum/go-ethereum/ethereum
ethereum -ws -loglevel=4
```
