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

o1js   npm version npm PRs Welcome

ℹ️ o1js is an evolution of SnarkyJS which saw 49 updated versions over two years of development with 43,141 downloads.

This name change to o1js reflects the evolution of our vision for the premiere toolkit used by developers to build zero knowledge-enabled applications, while paying homage to our technology's recursive proof generation capabilities.

Your favorite functionality stays the same and transitioning to o1js is a quick and easy process:

  • To update zkApp-cli, run the following command:

    npm i -g zkapp-cli@latest

  • To remove the now-deprecated SnarkyJS package and install o1js, run the following command:

    npm remove snarkyjs && npm install o1js

  • For existing zkApps, make sure to update your imports from snarkyjs to o1js

  • No need to redeploy, you are good to go!

o1js

o1js helps developers build apps powered by zero knowledge (zk) cryptography.

The easiest way to write zk programs is using o1js.

o1js is a TypeScript library for zk-SNARKs and zkApps. You can use o1js to write zk smart contracts based on zero-knowledge proofs for the Mina Protocol.

o1js is automatically included when you create a project using the zkApp CLI.
