What is the new behavior?

Now vvisp-config.js will be used instead of .env.
You can define those properties:

• networks: Define some network settings
• network: Define one of networks to use. Default: 'development'
• verboseRpc: Define verbosity of Rpc call
• from: Define private key or mnemonic words to use
• compilers: Define compiler setting to use

Example config file:

module.exports = {
  networks: {
    development: {
      host: 'localhost',
      port: 8545,
      network_id: '*', // eslint-disable-line camelcase
      gasLimit: 123123,
      gasPrice: 10000000000
    },
    coverage: {
      host: 'localhost',
      port: 8545,
      network_id: '*' // eslint-disable-line camelcase
    }
  },
  compilers: {
    solc: {
      version: '0.4.25', // Fetch exact version from solc-bin
      settings: {
        // See the solidity docs for advice about optimization and evmVersion
        optimizer: {
          enabled: false,
          runs: 200
        },
        evmVersion: 'byzantium'
      }
    }
  },
  from: { // or from: '0x9741fa712a6912b862c9043f8752ffae513cb01895985998c61620da5aaf2d2d'
    mnemonic: 'hello',
    index: 0
  }
}

vvisp-config.js can be compatible with truffle-config.js
You can use like below:

module.exports = {
  ...require('./truffle-config.js'),
  from: '0x9741fa712a6912b862c9043f8752ffae513cb01895985998c61620da5aaf2d2d'
}

or input option custom file name like:

vvisp deploy-service --configFile custom-config.js
