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

Crummy Ledger

Crummy Ledger is a Node JS module for creating distributed ledgers. Important features include:

  • Fully NodeJS (no built dependancies)
  • Fully Decentralized (no coordinators - no miners)
  • Byzantine Fault Tolerant (secure up to 1/2 faulty/dishonest, able to progress up to 1/3 faulty/dishonest)

Currently UNLICENSED - working on appropriate liscensing

Basic Documentation

npm install crummyledger
const Ledger = require("crummyledger");

async function main(){
  //initialize a distributed database with a base state, a directory for storing events locally, and a private key 
  var database = new Ledger({
    base_state: { counter: 0 },
    store_path: "./test_db",
    private_key: "0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f0f"
  });

  //Reducers define how different events effect the overall state
  database.setReducer('increment', function (state, issuer, payload) {
    state.counter++;
  });
  database.setReducer('add', function (state, issuer, payload) {
    state.counter += payload.amount;
  });

  //subscribe to milestone events to get notified of state changes
  database.onMilestone(async function () {
    console.log(await database.getState());
  });

  await database.init();

  //connect to tpeers to join the network
  database.connectTo(hostname_or_ipaddress, port, function () {
    console.log('connnected to a peer!');
  });

  //open a socket for incoming connections if you want others to be able to connect to you
  database.startServer(local_port, function () {
    console.log('I\'m ready for connections!');
  });

  //when you're all done
  database shutDown();
}

main();
