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 🙏

snaker工作流引擎web设计器

情怀!N年前使用的工作流引擎,虽然原作者已经不再维护,但是还是有那么一波人还在使用。个人看来其核心功能尚好,麻雀虽少,五脏俱全,是用来学习工作流引擎的好项目。但其流程设计器所用的技术栈可能就跟不上时代了(2016年前的开源项目)。为了让大伙或自己用得更舒心,或者也为了让更多人认识或重新认识这个工作流引擎。本人就花些许时间,使用现阶段前端主流的技术栈重新开发此款流程设计器。如大家在使用的过程中如有啥问题,欢迎留言或进群交流!
