Hugo core NFT contract

The contract defines core minting logic and NFTs metadata management. By metadata the following things are meant: attributes, their traits and IPFS CIDs for them.

See this contract, to understand NFT interface.

Testing

Primarly

1. development network is for running unit-tests defined in tests folder. Its id is 5777.
2. testing network is for manual tests, which are useful when integrating the project with the other ones. Its id is 6777.
3. Make sure you have npx package installed globally.

Unit-tests

All unit-tests are defined in tests/test_base.js. Simply run ganache client:

ganache-cli -p 7545 -i 5777 --allowUnlimitedContractSize  --gasLimit 0xFFFFFFFFFFFF

Then run tests with the following command:

npx truffle test --network=development

# or with events
npx truffle test --network=development --show-events

Manual tests

First, the contract should be migrated (deployed) to the test network. For that run ganache client with testing network id - 6777:

ganache-cli -p 7545 -i 6777 --allowUnlimitedContractSize  --gasLimit 0xFFFFFFFFFFFF

Then, run migrations (deploy contract):

npx truffle migrate --network=testing

Then, run any script that you want from scripts folder:

# for minting auto-generative NFTs
[deplyer@deployer] npx truffle exec scripts/mint.js --network=testing
Using network 'testing'.

If you want to redeploy the contract, simply run:

npx truffle migrate --reset --network=testing
# to redeploy only the contract, but not the contract/Mingrations.sol
npx truffle migrate --reset --f 2 --to 2 --network=testing

When contract is migrated to testing network, you can interact with it manually using console:

npx truffle console --network=testing

truffle(testing)> let a = await HugoNFT.deployed();
truffle(testing)> a.getNFT(0)
