Peerism API built with Truffle, Node.js, Express.js, Mongoose, MongoDB, Solidity, Ethereum TestRPC

• cURL is used to simulate a HTTP POST request from the Peerism React Native app to a Peerism API endpoint.
• The API routes uses an Express.js Middleware Chain to trigger compiling of the Peerism Smart Contract using the Solidity Compiler (Solc) and Ether Pudding, and then deploys it to the Ethereum TestRPC network and responds with the contract address. Efforts were made to incorporate Truffle.
