Unique Solidity interfaces

Usage

import {ethers} from 'ethers'
import {Address} from '@unique-nft/utils'
import {
  CollectionHelpersFactory,
  UniqueNFTFactory,
} from '@unique-nft/solidity-interfaces'

const provider = new ethers.providers.JsonRpcProvider('https://rpc-opal.unique.network')
const wallet = new ethers.Wallet('<Private key>', provider)

// or, with browser extension:
// const provider = new ethers.providers.Web3Provider(window.ethereum)
// const wallet = provider.getSigner()

const collectionHelpers = await CollectionHelpersFactory(wallet, ethers) // ethers parameter is optional
//when ethers not provided, it's been asynchronously loaded on demand to reduce package size and TTFP

const txCreateCollection = await (await collectionHelpers.createNFTCollection(
  'My Collection', // collection name
  'Fancy collection description', // collection description
  'MYCL', // token prefix - short, up to 4 letters string
  {value: await collectionHelpers.collectionCreationFee()}
)).wait()

const collectionAddress = txCreateCollection.events?.[0].args?.collectionId as string

// make collection ERC721Metadata compatible, to create necessary properties and activate
// corresponding supportsInterface and enable mintWithTokenURI and tokenURI methods 
//
// Actually it's optional but if we want to make it compatible with 
// common ethereum-world NFT collections, it's better to enable this compatibility.
// anyway, it just improves the collection and doesn't brake or mangle anything. 
const txMakeCompatible = await (await collectionHelpers.makeCollectionERC721MetadataCompatible(
  collectionAddress,
  '' // baseURI
)).wait()
console.log(`Collection #${collectionId} (address ${collectionAddress}) is now ERC721Compatible`)

const collection = await UniqueNFTFactory(collectionAddress, wallet, ethers)

const txMintToken = await (await collection.mintWithTokenURI(
  wallet.address,
  'ipfs://QmZ8Syn28bEhZJKYeZCxUTM5Ut74ccKKDbQCqk5AuYsEnp'
)).wait()

// this .toNumber() type casting is safe because tokenId upper boundary is 2**32
const tokenId = txMintToken.events?.[0].args?.tokenId.toNumber()
const tokenUri = await collection.tokenURI(tokenId)

console.log(`Successfully minted token #${tokenId}, it's URI is: ${tokenUri}`)
