Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Document Store

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

Prerequisite

  • Node (optionally, use nvm to manage node version)
  • Node version 18 onwards.

Installation

npm i @tradetrust-tt/document-store

Usage

To use the package, you will need to provide your own Web3 provider or signer (if you are writing to the blockchain).

Deploy new document store

import { deployAndWait } from "@tradetrust-tt/document-store";

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

Connect to existing document store

import { connect } from "@tradetrust-tt/document-store";

const documentStore = await connect("0x4077534e82c97be03a07fb10f5c853d2bc7161fb", providerOrSigner);

Interact with document store

const issueMerkleRoot = async () => {
  const documentStore = connect("0x4077534e82c97be03a07fb10f5c853d2bc7161fb", signer);

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

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

Provider & Signer

Different ways to get provider or signer:

import { Wallet, providers, getDefaultProvider } from "ethers";

// Providers
const mainnetProvider = getDefaultProvider();
const goerliProvider = getDefaultProvider("goerli");
const metamaskProvider = new providers.Web3Provider(web3.currentProvider); // Will change network automatically

// Signer
const signerFromPrivateKey = new Wallet("YOUR-PRIVATE-KEY-HERE", provider);
const signerFromEncryptedJson = Wallet.fromEncryptedJson(json, password);
signerFromEncryptedJson.connect(provider);
const signerFromMnemonic = Wallet.fromMnemonic("MNEMONIC-HERE");
signerFromMnemonic.connect(provider);

Setup

npm install
npm lint
npm test
npm truffle <command>

Contract Benchmark

A benchmark is provided to show the different transaction cost of the different variants of the document store.

npm run benchmark
