XState v5 Development

About

This skill provides comprehensive assistance for XState v5 development, focusing on the latest APIs and best practices. It enables the creation of complex, type-safe state machines using the setup() function and orchestrates sophisticated actor systems including promise, callback, and observable actors. Ideal for developers building predictable logic in JavaScript or TypeScript, it offers specific guidance on statechart design, transition debugging via the Inspection API, and seamless integration with modern frameworks while strictly adhering to v5-exclusive patterns.

Key Features

• Standardized patterns for actor communication, lifecycle management, and cleanup.
• Implementation patterns for various actor types including promise, callback, and RxJS observable actors.
• Statechart modeling guidance for hierarchical, parallel, and orthogonal state logic.
• Advanced debugging techniques using the XState Inspection API to monitor transitions and events.
• Type-safe machine configuration using the v5-native setup() function and TypeScript helpers.

Use Cases

• Designing and implementing complex UI state or business logic workflows.
• Orchestrating concurrent asynchronous processes and external service integrations via the actor model.
• Migrating existing XState v4 implementations to the modern v5 API and TypeScript 5.0+ requirements.
