Create a proxy state machine to drive CSS transitions on state changes with XState
In order to add some behaviors to a state machine, we can change it, or we can add another machine in front of it to delegate some responsibilities. In this article I present the machine we added in front of our main machine to manage the load button of our Turing machine visualizer.
Create stale data indicator with XState
The are few things as boring as not knowing the state of an application. Is this document saved or should I Ctrl+S? In this article I present the stale data indicator we display on our Turing machine visualizer when visualizer is not in sync with inputs.
Prevent flickering loading animation with XState
Loading indicators tell users that something is happening and will complete soon. They exist to improve UX, but they can worsen UX if they are directly hidden after underlying HTTP requests resolve. In this article I share XState patterns I used to prevent this issue in our Turing machine visualizer.
Orchestrate request for server-side execution of Turing machine with XState
We built a Turing machine visualizer but it does not execute machines itself—it's the job of an Erlang server. The visualizer needs to make a request to execute machines, and XState is the perfect tool to orchestrate this in combination with other behaviors of the visualizer.
Control tape of Turing machine visualizer with XState
The execution of a Turing machine with an input produces a list of operations on a tape, that are made to be visualized. I built such a visualizer with XState, and used cool patterns to visualize operations on the tape.
