Description

This project aims to solve the problem of tracking the full supply chain from the production of the coffee beans to the consumer hands.

This document uses UML to describre the general structure and functions that this Smart Contract offers to the actors:

• Farmers
• Distributors
• Retailers
• Consumers

Activity Diagram

This diagram shows the different actors and the interactions with the system.

Sequence Diagram

This diagram shows the communication between the different objects and their life cycle.

State Diagram

This diagram shows the different states of each object and the events or conditions that change those states.

Data Modeling Diagram

This diagram shows the different Smart Contracts and the relation between them

Getting Started

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.

Prerequisites

Please make sure you've already installed ganache-cli, Truffle and enabled MetaMask extension in your browser.

Give examples (to be clarified)

Installing

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/axelgalicia/blockchain-supply-chain/tree/master/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 "siege disagree message lake agree between walk confirm engage survey chicken become"

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 10 tests should pass.

In a separate terminal window, launch the DApp:

npm run dev
