Front-end Project Setup

1. cd frontend
2. npm install
3. REACT_APP_CONTRACT_ADDRESS=0xe0003E2e604A1Fce6D2Ebc5933De49419CA6f80F npm run start
   http://localhost:3000

Backend Project Setup using the existing deployed contract. You can borrow a book and return the book using the same metamask account used in borrowing book.

1. At the root folder: npm install
2. Add .env file in the root folder and add the following: MOONBASE_URL, PRIVATE_KEY, REACT_APP_CONTRACT_ADDRESS

To Add Book, compile and deploy a new contract. Otherwise, you will ecnounter a contract error: Contract was not called by the owner.

1. At the root folder: npm install
2. Add .env file in the root folder and add the following: MOONBASE_URL, PRIVATE_KEY, REACT_APP_CONTRACT_ADDRESS. Removed 0x in hardhat.config.js as it is working without that.
3. Delete the artifacts folder under frontend/src
4. npx hardhat run scripts/deploy.js --network moonbase
5. REACT_APP_CONTRACT_ADDRESS= npm run start http://localhost:3000
