Getting setup to work with Solidity on the Ethereum Blockchain.

Technologie

Setting Up a Solidity
Environment
By Angello Pozo & Jason Robert

What is Solidity?
• Compiles down to op codes that are run on Ethereum
• Use the Blockchain as a server and a DB

For Local Development
• Node.js (system program)
• Solc (npm package)
• Truffle (npm package)
• Testrpc (npm Package)

Installing Node
Mac
1. Install Homebrew
(https://brew.sh)
2. Open command line
1. brew install node
2. node -v
Windows
• Go to https://nodejs.org/en/
• Open command line
• node -v

Install Global NPM Packages
1. In command line
1. npm install solc –g
2. npm install truffle –g
3. npm install ethereumjs-testrpc -g

Creating Project with Truffle
• In the command line
• cd ~ && mkdir code && cd code
• truffle init
• ls -la
• Open a new terminal tab or window
• testrpc

Let’s See it Working!!
• Command line
• truffle compile
• truffle migrate –reset
• truffle test

Minor Change to Tests
• Go to link
• Short  http://bit.ly/2o6lM5L
• Raw  https://gist.github.com/sogoiii/d3b512aab0623d4ad1da5c5bde3d3323
• Copy and paste over the `./test/metacoin.js` file
• Run `truffle test` in command line
