Ethereum JavaScript API
This is the Ethereum compatible JavaScript API which implements the Generic JSON RPC spec. It's available on npm as a node module, for bower and component as an embeddable js and as a meteor.js package.
You need to run a local ethrereum node to use this library.
Installation
Node.js
$ npm install ethereum.js
Meteor.js
$ meteor add ethereum:js
As Browser module
Bower
$ bower install ethereum.js
Component
$ component install ethereum/ethereum.js
- Include
ethereum.min.js
in your html file. (not required for the meteor package) - Include bignumber.js (not required for the meteor package)
Usage
Require the library (not required for the meteor package):
var web3 = require('web3');
Set a provider (QtSyncProvider, HttpProvider)
web3.setProvider(new web3.providers.HttpProvider('http://localhost:8545'));
There you go, now you can use it:
var coinbase = web3.eth.coinbase;
var balance = web3.eth.getBalance(coinbase);
For another example see example/index.html
