This repository containts an Ethereum DApp that demonstrates a Supply Chain flow. A poultry can add new chickens to the inventory system stored in the blockchain. Slaughter House can purchase a healthy chicken from the poultry. It can then slaughter the chicken in a halal way and then sell the halal chicken to consumers.
The DApp User Interface when running should look like...
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
Please make sure you've already installed NodeJS, ganache-cli, Truffle and enabled MetaMask extension in your browser. If you want / have multiple versions of NodeJS on your system, Node Version Manager (nvm) is a very handy tool. You'll need 4 different accounts on your MetaMask to test all stages of the halal chain. You may use the accounts mentioned in 0_ganache-cli.txt.
A step by step series of examples that tell you have to get a development env running
Clone this repository:
git clone https://github.com/udacity/nd1309/tree/master/course-5/project-6
Change directory to project-6 folder and install all requisite npm packages (as listed in package.json):
cd project-6
npm install
Launch Ganache:
ganache-cli -m "spirit supply whale amount human item harsh scare congress discover talent hamster"
Your terminal should look something like this:
In a separate terminal window, Compile smart contracts:
truffle compile
Your terminal should look something like this:
This will create the smart contract artifacts in folder build\contracts.
Migrate smart contracts to the locally running blockchain, ganache-cli:
truffle migrate
Your terminal should look something like this:
Test smart contracts:
truffle test
All tests should pass.
In a separate terminal window, launch the DApp:
npm run dev
