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 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.
