# 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. |
||||
|
||||
For an example see `index.html`. |
||||
|
||||
**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 |

# Ethereum JavaScript API |
||||
|
||||
This is the Ethereum compatible [JavaScript API](https://github.com/ethereum/wiki/wiki/JavaScript-API) |
||||
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] |
||||
|
||||
<!-- [](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 [bignumber.js](https://github.com/MikeMcl/bignumber.js/) |
||||
|
||||
## 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: |
||||
|
||||
``` |
||||
var coinbase = web3.eth.coinbase; |
||||
var balance = web3.eth.balanceAt(coinbase); |
||||
``` |
||||
|
||||
|
||||
For another example see `example/index.html`. |
||||
|
||||
