How to setup ethereum node for development

Seems that all you need is to setup and run the latest testrpc ethereum network emulator https://github.com/ethereumjs/testrpc

Setup node.js dev environment

1. Install truffle
2. Then run truffle compile, then run truffle migrate to deploy the contracts onto your network of choice (default "development").
3. Then run npm run dev to build the app and serve it on http://localhost:8080

web3.js notice

Currently unable upgrade to web3.js v1.x.x due the following reasons:

• ganacha-core (testrpc) doesn't support WS connection yet while v1.x.x requires it https://github.com/trufflesuite/ganache-core/pull/14
• truffle doesn't support web-packed v1.x.x requiring a lot of broken dependencies
