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.

@enfo/shake-state-machine

Remove unused states from an AWS State Machine definition with minimal effort

Usage

npm i @enfo/shake-state-machine -g

Add a state machine definition to your clipboard with your desired start state as StartAt. Invoke the package and if all went well your clipboard will now contain a state machine with no unreachable states.

shake-state-machine

Alternatively the package can be invoked using npx.

npx @enfo/shake-state-machine

Practical example

Let us have a look at an AWS State Machine definition.

Hello World State Machine

Execution is successful.

Successful execution

Let us try to modify the State Machine so it skips the Hello state and starts at World. Attempting to save will result in an error regarding an unreachable state.

State "Hello" is not reachable

Copy the definition into your clipboard and run the package. Paste to the definition input field afterwards

shake-state-machine

Just World

The new state machine definition is ready to be used. When used in the wild you can have your State Machine fixed in a matter of seconds!

How it works

Under the hood the package runs a Depth-first search starting at StartAt. After completing it builds a new state machine using only the visited states.
