Suggestion about tools that could help

[sneko]

Hi @davidkpiano!

I was watching some of your videos because I was trying to find a library to manage routing in Vue.js through Finite State Machines. For now, I didn't find a good and maintained one that would be well-integrated to this framework but I keep looking for.

On the other hand, I wanted to tell you that I already used statecharts through JS apps. And I have some suggestions that could help you:

• I was using Qt Creator with their SCXML plugin to define grafically my statecharts. That's free :)
• Then, I was able to export this file as SCXML one
• I was using the SCION library in JavaScript to parse the SCXML and broadcast events inside my FSM (https://github.com/jbeard4/SCION)

I don't know if you have heard about these tools or if it's too late to integrate SCION in xstate... but I hope it will be useful to your progress.

EDIT: Note that both tools are managing nested states, history... They are really powerful 😀

Hey @sneko - SCXML compatibility and integration is what we're currently working on - and it's almost done!

When that's done, you'll be able to use Qt Creator the exact same way with xstate, or any other tools that work with SCXML.

There are many key differences between SCION and xstate however, including the representation of states (hierarchical object-based vs. arrays), and that xstate is meant to be a superset of SCXML - we plan to support more than just core SCXML functionality, but also other ideas discussed in the original paper, such as parametric states and activities.

Also, xstate is meant to be interpreter-agnostic, leaving you to use any interpreter you desire, or make your own.

So keep a lookout for SCXML compatibility 🔜 !
