Smart Contract - step by step

Versions

Run truffle version command:

Package	Version
Truffle	v5.1.58 (core: 5.1.58)
Solidity	0.6.12 (solc-js)
Node	v14.15.1
Web3.js	v1.2.9

As configured in truffle-config.js the smart contracts was compiled successfully using:

• solc: 0.6.12

Steps to Install the Environment

Node.js

Install a clean version of nodejs. I´m using the nvm (Node Version Manager) tool to allow install and switch between versions. Currently the version 14 of node.js works:

nvm install 14.15.1
nvm use 14.15.1

Truffle and other packets

install truffle, openzelepin, webpack and dependences:

cd DrugChain\
npm i -g truffle
npm i --save openzeppelin-solidity
npm i --save truffle-hdwallet-provider
npm i --save-dev eth-gas-reporter
npm i truffle-assertions
npm i -g webpack
npm i -g webpack-dev-server webpack-cli webpack-dev-middleware webpack-hot-middleware copy-webpack-plugin

To compile and run tests

For starting the development console, run:

truffle develop

For compiling the contract, inside the development console, run:

compile

For migrating the contract to the locally running Ethereum network, inside the development console, run:

migrate --reset

For running unit tests the contract, inside the development console, run:

test

Deployment

Ganache

npm install -g ganache-cli

create a file called ./secret.txt with your mnemonics of your wallet, like:

skin impose this task range body amused apple spin jazz inhale bench

edit line 24 of ./truffle-config.js and replace with your Infura Key:

24:   const infuraKey = "c216...";	// INFURA - PROJECT ID

Get some funds

First send some funds to your account. Use Ganache to get the addess of the first account from your secrets.txt mnemonic. Go to https://faucet.rinkeby.io/ and send a tweet as instructions. Copy-paste your tweet url and have fun!

To deploy in Rinkeby

Then, execute the command:

truffle migrate --network rinkeby --reset

Deployment Terminal Output

.\DrugChainDAPP> truffle migrate --network rinkeby --reset
