ember-web3

This add-on is simplifies integrating Web3 into your Ember.js web app. For more information on Web3 visit: https://github.com/ethereum/web3.js/

Installation

• ember install ember-web3

Usage

Inject the service where needed.

web3: Ember.inject.service(),

• Define web3 provider and call the setup method passing in the provider.

  let provider = window.web3.currentProvider;
  let web3Instance = this.get('web3').setup(provider);

Ex. of using localhost as provider

  let provider = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"))
  let web3Instance = this.get('web3').setup(provider);

web3 Instance

Service injection gives access to object Web3, and instantiates a web3Instance object using the provider specified in the config. To retrieve the web3 instance:

let webInstance = this.get('web3.web3Instance');

Or simply create your own

let web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));

Contract Instance

The service also allows you to simply retrieve a deployed contract instance of existing Solidity contract using the ABI and address. Requires the ABI array and address. Returns a promise.

let contractABI = ['ABI array'];
let contractAddres = '0x6e93b795ba20f376e205d00c205eaa8cc10db9f7' // Not real a contract address
web3Instance.contract(contractABI, contractAddress).then((contract) => {
  // do something with contract
});

The most recently retrieved contract will be set to contractInstance on the service.

let contractInstance = this.get('web3.contractInstance');
