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