bower install cita-web3
- Include
web3.min.js
in your html file. (not required for the meteor package)
Use the web3
object directly from global namespace:
console.log(web3); // {eth: .., shh: ...} // it's here!
Set a provider (HttpProvider)
if (typeof web3 !== 'undefined') {
web3 = new Web3(web3.currentProvider);
} else {
// set the provider you want from Web3.providers
web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:1337"));
}
Set a provider (HttpProvider using HTTP Basic Authentication)
web3.setProvider(new web3.providers.HttpProvider('http://host.url', 0, BasicAuthUsername, BasicAuthPassword));
There you go, now you can use it:
var coinbase = web3.eth.coinbase;
var balance = web3.eth.getBalance(coinbase);
