Hey everybody, this is the second post of the series on writing apps the Git way, where you just go take a cup of coffee and browse a Git repo to learn something new!

Be sure to take it step by step, if you’re a new kid on the block.

Today we’re going to write a Node.js app for the purpose to interact with our shiny new first Solidity smart contract deployed on the Ropsten testnet already – which remember, basically outputs the

Hello world!string.

The code is available at programarivm/solidity-interacting-with-nodejs.

Here is the git log for you to get the application up and running.

$ git log --oneline 45e59bd (HEAD -> master) app.js is implemented 80195ad npm install web3 dotenv 97a0d34 .gitignore is added fdd0e78 npm init
