App Summary

Registered and Paid airlines can:

All users can:

• Request a flight be registered as available for purchasing insurance
• Purchase insurance
• Check the status of their flight
• If the flight status is returned as 'LATE AIRLINE', can request a refund

Running the app

• Run Ganache CLI or truffle develop
• Pull down the code from GitHub

Contracts

• Run truffle compile and truffle migrate commands from the root directory

The Front-End

• cd react-app
• yarn start

The Back-End

• cd server
• yarn start

Run Tests

• Run Ganache CLI or truffle develop
• Update truffle-config.js with correct host port
• Run truffle test from the root directory

Tests

• Mocha for contract tests
• Errors visible in console logs are confirming failure when account with wrong permissions attempts an action.
• See Tests Here

Required Libraries

• Truffle v5.3.6

• Solidity v0.8.0

• Web3 v1.3.0

• Express v4.6.0

• Node v14

• These libraries are required for this project. I used more recent versions than in the course outline as I want my learning to be as current as possible.

Optional Libraries

• Create React App. Used to provide a great starting point for the UI. As a Senior Front-End Developer who works daily with React, this is a great tool for getting a modern Front-End up and running quickly.

• Ganache. Used for local development before deploying my contracts to the Rinkeby Test Network. Used with Ganache UI as it provides useful real-time updates on transactions.

Notes for Reviewer

• I reduced the amount needed to fund an airline from 10 Ether to 1 Ether to save on Testnet funds.
• I did the same for registering as an Oracle
