Hoffdapp

Ethereum smart contract showcase.

Docker setup:

Run ethereum testrpc: docker run --rm -d --name testrpc -p 8545:8545 desmart/testrpc:latest

Run container with truffle dev framework (start this command in truffle folder): docker run -it --rm -v "${PWD}:/usr/src/app" --link testrpc -e "RPC_HOST=testrpc" --entrypoint=/bin/sh desmart/truffle:3.2

Compile:

in truffle docker container: truffle compile

Deploy to ethereum network

in truffle docker container: truffle migrate

to redeploy: truffle migrate --reset

interacting with deployed smart contract

in truffle docker container: start truffle console: truffle console

load instance of deployed contract:

var hoff;
HoffDapp.deployed().then(function(instance){hoff=instance});

load user accounts into variables

var admin = web3.eth.accounts[1]
var user = web3.eth.accounts[2]

add admin to contract

hoff.addAdmin(admin)

check if admin

hoff.isAdmin.call(admin).then(console.log)

add user from admin account

hoff.addUser(user,"John Doe", {from:admin})

get user info from contract

hoff.getUser.call(user).then(console.log)

add menu - called from admin account

hoff.addMenu("id1","Burger",750, {from:admin})

consume menu - called from user account

hoff.consumeMenu("id1", {from:user})

To compile abi and bin files of smartcontract for e.g. web3j run: docker run -v ${PWD}/contracts:/src -v ${PWD}/build/contractArtifacts:/build ethereum/solc:stable /src/HoffDapp.sol --bin --abi --optimize -o /build
