Migration 0.13.0 -> 0.14.0
web3.js version 0.14.0 supports multiple instances of web3 object. To migrate to this version, please follow the guide:
-var web3 = require('web3');+var Web3 = require('web3');+var web3 = new Web3();
Expanse Support
This API has been modified to support both Expanse and Ethereum Applications. Calls may be made through either web3.exp or web3.eth interchangably and both Ethereum and Expanse units are supported. For information on porting software that uses ethereum to expanse, please see our Expanse/Ethereum Cross Compatibility Guide
Expanse and Ethereum JavaScript API
This is the Ethereum and Expanse 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 Ethereum node to use this library.
Installation
Node.js
npm install @expanse/web3
Meteor.js
meteor add expanse:web3
As Browser module
Bower
bower install web3-expanse
Component
component install expanse-org/web3.js
- Include
web3.min.js
in your html file. (not required for the meteor package)
Usage
Use the web3
object directly from global namespace:
console; // {eth: .., shh: ...} // it's here!
Set a provider (HttpProvider)
Expanse: ```js web3.setProvider(new web3.providers.HttpProvider('http://localhost:9656'));
Ethereum: ```js
web3.setProvider(new web3.providers.HttpProvider('http://localhost:8545'));
There you go, now you can use it:
var coinbase = web3ethcoinbase;var balance = web3eth;
or
var coinbase = web3expcoinbase;var balance = web3exp;
You can find more examples in example
