Installation

We recommend switching to Node.js version 14.15.0 to make sure common crypto dependencies work. Execute nvm use, if you have Node Version Manager.

Then, in your project, run:

npm install --save double_eth

Install web3 too if you haven't already.

If you run into an error while building the dependencies and you're on a Mac, run this:

xcode-select --install # Install Command Line Tools if you haven't already.
sudo xcode-select --switch /Library/Developer/CommandLineTools # Enable command line tools
sudo npm explore npm -g -- npm install node-gyp@latest # (Optional) update node-gyp

import { Double } from "../src/double";
var contract = new web3.eth.Contract(DONFT_ABI, DONFT_LAND);
let landId = "340282366920938463463374607431768211458";
let tokenId = 2;
let durationId = 2;
let duration;

let info = await Double.getDoNftInfo(contract, tokenId);
console.log("info", info);

duration = await Double.getDuration(contract, durationId);
console.log("duration", duration);

duration = await Double.getDurationByIndex(contract, tokenId, 0);
console.log("duration", duration);

let durationIds = await Double.getDurationIdList(contract, tokenId);
console.log("getDurationIdList:", durationIds);

let originalAddress = await Double.getOriginalNftAddress(contract);
console.log("getOriginalNftAddress:", originalAddress);

let oid = await Double.getOriginalNftId(contract, tokenId);
console.log("getOriginalNftId:", oid);

let walletAddress = "0xfB7ff746A0aeBDE0012813565FC3Fb8281f23E01";
let tokenIds = await Double.getTokensOfOwner(contract, walletAddress, 0, 0);
console.log("getTokensOfOwner:", tokenIds);

let user = await Double.getUser(contract, tokenId);
console.log("getUser:", user);

let vNftId = await Double.getVNftId(contract, landId);
console.log("getVNftId:", vNftId);

let mNftId = await Double.getWNftId(contract, landId);
console.log("getWNftId:", mNftId);

let isValid = await Double.isOriginalValidNow(contract, landId);
console.log("isOriginalValidNow:", isValid);
