### 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);
|
|
});
|
|
```
|
|
