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 🙏

jbook

jbook is a TypeScript course from Stephen Grider on Udemy in which we are building an interactive browser-based coding environment. It's like a Jupyter Notebook, but for Javascript, with many additional features added in.

We will solve incredible challenges around bundling and transpiling code directly in the browser. This is a task normally done by running Webpack and Babel at your terminal We will execute users' code safely in the browser just like how famous services like CodeSandBox and CodePen do. Finally, we'll deploy this project using a multi-package architecture to NPM, where your friends and employers can easily download and run your project.

Here's a partial list of the topics that will be covered in this course:

  • Master the use of React, Redux, and Typescript together
  • Build a complex and interesting app using a package-based architecture
  • Understand the challenges of in-browser code transpiling and and processing
  • Secure your app against potential security exploits
  • Safely execute user-provided code directly in the browser
  • Run a code editor directly in the browser - the same editor used by VSCode!
  • Leverage Web Assembly to run a code bundler directly in the browser at lightning-fast speeds
  • Use the internals of Redux to manually test out your business logic
  • Discover dozens of tricks to build a sleek UI
  • Deploy your app to the NPM registry, where others can easily use it
