Usage

To deploy the contract MyContract do the following:

const {
    deployContracts
} = require('@nevermined-io/contract-tools')

await deployContracts({
    // web3, coming from truffle
    web3,
    // artifacts, coming from truffle
    artifacts,
    evaluateContracts: ({
        contracts = []
    } = {}) => {
        // decide which contracts to deploy here
    },
    initializeContracts: async ({
        contracts,
        roles,
        network,
        verbose = true
    } = {}) => {
        // call the initializer of each contract here
    },
    setupContracts: async ({
        addressBook,
        artifacts,
        roles,
        verbose
    } = {}) => {
        // call the contracts here to set them up
    },
    contracts: [
        'MyContract'
    ],
    // forces the creation of wallets all the time
    forceWalletCreation: true,
    // clean zos session files
    clean: true,
    // clean zos files and wallets on the current network as well
    deeperClean: true,
    // are we going to deploy to a testnet or a mainnet?
    testnet: false,
    // be verbose or not
    verbose: true
})
