Brief description

An event ticketing app with low transaction fees and blockchain-driven anti-scalping protections

How to run the dapp (test.js file)

1. Open the Ganache app (dock)

   a. Open the hard-to-find-sponge workspace

2. Open the Metamask browser extension (Google Chrome)

   a. Log in if needed

   b. Switch to the Ganache TEST network

3. In Terminal, cd into the project directory

4. In Terminal, run truffle compile

5. In Terminal, run truffle migrate --reset (pushes new code to the blockchain!)

6. In Terminal, run truffle console (optional)

   a. If so desired, run the following test commands:

    `marketplace = await Marketplace.deployed()`
    
    `marketplace.address`
    
    `name = await marketplace.name()`
    
    `name`
    
    `sup = await marketplace.supervisor()`
    
    `sup`
   

7. In Terminal, run truffle test

How to run the dapp (Remix IDE)

1. Open remix.ethereum.org

2. Upload any relevant .sol files to the File Explorer

3. In the Solidity Compiler tab, do the following:

   a. Choose the correct compiler given the .sol files

   b. Compile the selected code

4. In the Deploy and Run Transactions tab, do the following:

   a. In the Environment dropdown menu, choose the JavaScript VM

   b. In the Account dropdown menu, choose the first address to deploy the contract

   c. Press the Deploy button

   d. Click on the dropdown menu that says Marketplace at (some address)

   e. Test the various functions, e.g., createProduct, purchaseProduct, and others

    i. Recommendation: use the second address as ticket issuer, and use the third address as ticket holder
   

5. If errors arise in the console, press the Debug button to view line-by-line code execution

How to run the dapp (npm frontend)

1. Open the Ganache app (dock)

   a. Open the hard-to-find-sponge workspace

2. Open the Metamask browser extension (Google Chrome)

   a. Log in if needed

   b. Switch to the Ganache TEST network

3. In Terminal, cd into the project directory

4. In Terminal, run npm run start

Untested functionalities

Should I be using modifiers to collapse duplicate code as much as possible? Or will I cause high gas/security problems?
