One of our most-requested features has just landed in the Stately Studio; you can now import your machines from code!
Watch import from code in action in our latest video.
Importing from code is handy if you’ve already built machines while working with XState, or have created a machine using our older Stately Viz and haven’t yet tried the Stately visual editor.
The Stately team has got some huge features to share with you soon. We’ve been working hard through the summer, which is why we’re already halfway into September by the time I’ve gotten around to this update post.
Farzad and David add more features to their resizable panel using XState and React. Watch Part 1.
Check out the accompanying code on Code Sandbox.
Farzad and David use XState to build the logic for a resizable panel with React in an impromptu live stream.

From fetching data to fighting with imperative APIs, side effects are one of the biggest sources of frustration in web app development. And let’s be honest, putting everything in useEffect hooks doesn’t help much.
Thankfully, there is a science (well, math) to side effects, formalized in state machines and statecharts, that can help us visually model and understand how to declaratively orchestrate effects, no matter how complex they get. In this talk, David ditches the useEffect hook and discovers how these computer science principles can be used to simplify effects in our React apps.
Using the XState extension for VS Code, you can create a state machine in seconds and edit the machine using our visual editor. Use the xsm snippet to quickly generate the code required for your state machine, then drag and drop inside our visual editor to rapidly model your machine.
Our XState VS Code extension has now been installed 10k times! Install the extension yourself from inside VS Code or find the XState extension on the Open VSX Registry to enjoy the following new features.
Are you a React developer using XState to model your application logic? Perhaps you’ve heard of XState but have been looking for an easy way to try it out in one of your projects. If so, then I’d like to share with you a pattern I was introduced to when first diving into codebase at Stately, that of using custom machine hooks. This lightweight, reusable way to integrate XState into React components is a delight to work with and I think you might like it as much as I do!
On top of our usual minor improvements and bug fixes, we’ve got great new features to share with you in July!
XState can be used wherever JavaScript runs, whether on the backend or frontend. Because the code it creates can be visualized, it’s great at handling complex use cases - being able to see what a complex piece of code does can be extremely useful.
Let’s look at each use case one-by-one.
