Ethereum JavaScript API
This is the Ethereum compatible JavaScript API using Promise
s
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);
});
