Document Store

This repository contains both the smart contract code for document store (in /contracts) as well as the node package for using this library (in /src).

Installing Package

npm i @tianhr/hedera-document-store

Package Usage

To use the package, you will need to provide your own Hedera account (if you are writing to the blockchain).

Generate hedera Client

import { deployAndWait } from "@tianhr/hedera-document-store";

const hederaClient = await generateHederaClient(AccountId,Privatekey);

Deploying new document store

import { deployAndWait } from "@tianhr/hedera-document-store";

const documentStore = await deployAndWait("My Document Store", hederaClient);
console.log(documentStore);

Connecting to existing document store on Hedera

import { connect } from "@tianhr/hedera-document-store";

const documentStore = await connect("0.0.0000000", hederaClient);

Interacting with the document store (example)

const issueMerkleRoot = async () => {
  const documentStore = await connect("0.0.2803637", hederaClient);

  const tx = await documentStore.issue("0x7fe0b58ed760804eb7118988637693c4351613be327b56527e55bcd0a8d170d7");
  console.log(tx[1].receipt);

  const isIssued = await documentStore.isIssued("0x7fe0b58ed760804eb7118988637693c4351613be327b56527e55bcd0a8d170d7");
  console.log(isIssued);
};
