Understanding the Actor Model
I'm not familiar with the actor model, so I Googled. Sorry for the dumb questions below, but I want to get a sense of it ... Will actors in xstate essentially be independent states (that can contain substates), or something else? Does each actor have an independent FIFO queue of…

How should I handle non-serializable references
I've got a scenario where I have a class custom-built to accept and provide flexible access inside arbitrary sets of data (the Hierarchy). While I could serialize it, one of the main advantages is simply letting it maintain the only reference to the often massive amount of data…

We're in the endgame, now... (refactoring existing component)
Hello. I've got a component I'd like to refactor to use xstate, because as soon as people in my company saw it they wanted to reuse it everywhere. What I'm going to link to is one specific implementation of the template (the "rules building" page) but fundamentally it's allowing…
