How to Use

Imports

import Vault from '@zippie/vault-api'
import * as zippieprovider from '@zippie/vault-web3-provider'
import * as Web3 from 'web3'

Initialise the Vault

this will redirect the user on boarding if required

const vault = new Vault()
vault
  .setup()
  .then(_ => {
    vault.signin().then(_ => {
    console.log('Initialised Vault: ' + result)
    })
  },
  (error) => {
    console.log('Error initialising vault: ' + error)
  }
);

Initialise Web3 Provider

on the ethereum network of your choice .eg kovan, ropsten, mainnet

var ethereum = zippieprovider.init(vault, { network: 'kovan' })

Add Accounts

Set up some accounts using a vault key path

 zippieprovider
  .addAccount('m/0')
  .then((address) => {
    console.log(address)
  }
);

Initialise Web3.js

and finally set up Web3.js

if(window.web3 === undefined) {
  window.web3 = new Web3(ethereum)
}

web3.eth.getAccounts()
  .then((accounts) => {
    console.log('accounts: ' + accounts)
  }
);

After that you now have a working web3.js object and can use the standard API.
