NftCreator

This is the repo to create NFTs on EVM compatible blockchains (able to run solidity code).

how to run in cloud environment

1. clone the code in your system.
2. Install all the dependencies by running : npm install
3. Add a secret.json in the root directory, in below format:

{
    "alchemyApiKey": "<alchemy_api_key>",
    "privateKey": "<wallet_account_private_key>",
    "sendridApiKey": "<sendgeid_api_key>"
}

4. Run the server by connecting to Rinkeby network by running npx hardhat run --network rinkeby app.js

how to run on local system

1. clone the code in your system.
2. Install all the dependencies by running : npm install
3. start a local blockchain by running npx hardhat node
4. In another terminal window compile the smart contract, npx hardhat compile
5. deploy the smart contract on local blockchain, npx hardhat run --network localhost scripts/deploy.js

By now following things are happening in your system:

1. a local blockchain is running
2. smart contracts under the directory contracts/solidity have been deployed on this blockchain

Next: start your nodeJs server by running npx hardhat run --network localhost app.js Now, you nodeJs server is running at port 3000.

making REST request to createNFTs to the server

1. Curl to create a NFT token

curl --location --request POST 'localhost:3000/createNft' \
--header 'Content-Type: application/json' \
--form 'file=@"/Users/vg/Documents/nft images/1.jpeg"' \
--form 'mintTo="0xb8FAAB1f7f19E7021A8736777d7D0d75b7bdFcbc"' \
--form 'name="cool dude"' \
--form 'description="a cool new nft token"'

if you wish then you can update the mintoTo and tokenUri values.

2. curl to query the owner of a token Id

curl --location --request POST 'localhost:3000/ownerOf' \
--header 'Content-Type: application/json' \
--data-raw '{
    "tokenId" : 1
}'

3. curl to get the URI of the token

curl --location --request POST 'localhost:3000/tokenURI' \
--header 'Content-Type: application/json' \
--data-raw '{
    "tokenId" : 1
}'

paste the request curl in the postman and you will be able to interact with NFT smart contract deployed.
