Blockchain Webapp

Setup and run webapp

1. Install node and npm (https://nodejs.org/en/download/package-manager)
2. Clone repo https://github.com/johnfoley14/BlockchainWeb3DApp
3. Navigate into project directory cd .\ticket-system-webapp\
4. Install necessary packages npm i. If you have errors installing dependencies, please refer to section at end of README.
5. Run local development environment npm run start

Note on use for demo

The following may be done when demoing the webapp

1. If encountering CORs errors when demoing project, try using chrome with chrome.exe --user-data-dir="C://Chrome dev session" --disable-web-security.
2. Feel free to change doorman address in App.js. This will allow you to fully demo redeeming a ticket as the doorman would. This however requires the doormans private key. A doorman can be any wallet created on http://localhost:3000/createWallet. I have also given links to successful use of this page in the report under Successful Links and Transactions.

Testing using jest and truffle

Two testing frameworks are currently in use:

1. Jest for testing frontend rendering and low level logic
2. Truffle for testing the smart contract functions and testing contract deployment

Running tests:

1. To run Jest test suite: npm test
2. To run Truffle smart contract tests: truffle test
3. To test smart contract deployment with truffle: truffle develop. This should create a local development blockchain at http://127.0.0.1:9545/. Next deploy smart contract with migrate --reset

Errors installing npm dependencies
