# 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 |

|
|

|
<!-- [](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 |
||||
|
``` |
