DApp-721

The repository includes:

A Smart contract that is able to deploy NFT collections
and mint NFTs on all the previously collections

A backend server that listens to the emited events and caches them
and provides the dApp with relevant data

A dApp which features the creation of new collections and NFTs

Quick start

The first things you need to do are cloning this repository and installing its dependencies:

git clone https://github.com/sacredwx/dapp-721
cd dapp-721
npm install

Once installed, let's run Hardhat's testing network (Optional, if you run locally):

npx hardhat node --hostname 127.0.0.1

Then, on a new terminal, go to the repository's root folder and run this to deploy your contract to the network of your choice (localhost / goerli):

npx hardhat run scripts/deploy.js --network {network}

A .env file is located in 'backend/.env' shall be populated with proper values:

PORT=80
RPC_ENDPOINT=http://127.0.0.1:8545/
PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

Then, we need to run the backend with:

cd backend
npm install
npm run dev

Finally, we can run the frontend with:

cd frontend
npm install
npm start

Open http://localhost:3000/ to see your Dapp. You will need to have Metamask installed and listening to localhost 8545.

Invalid nonce errors: if you are seeing this error on the npx hardhat node console, try resetting your Metamask account. This will reset the account's transaction history and also the nonce. Open Metamask, click on your account followed by Settings > Advanced > Reset Account.
