Overview

Product summary

Review the store description, core capabilities, and common use cases.

XState Ninja is a devtool panel for tracking state machines implemented with the XState library. It provides a better developer experience than the widely used Redux devtools extension for monitoring state machines. XState Ninja is more ergonomic and removes common pain points experienced with Redux devtools:

👉 more than one machine can be tracked at once in multiple swimlanes

👉 machine state is clearly visible (including parallel states)

👉 no events are missed regardless of when the devtool was opened

👉 side effects (invoked services and actions) are clearly visible

👉 all invoked or spawned actors are monitored, including invoked/spawned callbacks and promises
