Running this project

Local setup

To run this project locally, follow these steps.

1. Clone the project locally, change into the directory, and install the dependencies:

git clone https://github.com/mazhar11-cou/DigitalStack-A-NFT-Marketplace.git

cd DigitalStack-A-NFT-Marketplace

# install using NPM or Yarn
npm install

# or

yarn

2. Start the local Hardhat node

npx hardhat node

# or

yarn hardhat node

3. With the network running, deploy the contracts to the local network in a separate terminal window

npx hardhat run scripts/deploy.js --network localhost

# or 

npx hardhat run scripts/deploy.js --network localhost

4. Start the app

npm run dev

# or

yarn dev

Configuration

To deploy to Polygon test or main networks, update the configurations located in hardhat.config.js to use a private key and, optionally, deploy to a private RPC like Infura.
