README.md

Ethereum JavaScript API

This is the Ethereum compatible JavaScript API using Promises which implements the Generic JSON RPC spec. It's available on npm as a node module and also for bower and component as an embeddable 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 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.

To install ethereum and spawn a node:

go get github.com/ethereum/go-ethereum/ethereum
ethereum -ws -loglevel=4
