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

Yardbirds Solidity

Yardbirds is a library for writing flexible modular Smart Contract applications on Ethereum.

Yardbirds is based on OpenZeppelin library and provides modificated and extended contracts to cover surtain usecases.

  • Decentralised smart-contract based applications should be upgradable and mantainable just like any other application
  • Upgradability and mantainablity can be achieved by modularity
  • Modularity can be achieved by segregating responsibilities
  • Mantainablity is also a human-mistake tolerancy (where possible)
  • Entry-point contracts should be replaced much less often than internal
  • Entry-point contracts should be simple for not being upgraded frequently

Getting Started

Yardbirds integrates with Truffle and Embark.

truffle

To use with Truffle, first install it and initialize your project with truffle init.

npm install -g truffle
mkdir myproject && cd myproject
truffle init

Embark

To use with Embark, first install it and initialize your project with embark new MyApp.

npm install -g embark
embark new MyApp
cd MyApp

Contracts

  • token
    • ERC20
      • mintable
        • SegMintableToken - OpenZeppelin's MintableToken with segregated transferrable minter role
        • SegMintableFinishableToken - SegMintableToken with ability to finish minting forever
