State Machine Architecture

Built on XState for predictable, debuggable, and maintainable application state.

Why State Machines?

Traditional CMS platforms often suffer from unpredictable state management—race conditions, impossible states, and debugging nightmares. SveltyCMS solves this with XState state machines.

No Impossible States

State machines make invalid states unrepresentable. Your CMS can never be in a broken or undefined state.

Time Travel Debugging

Replay state transitions, inspect history, and understand exactly how you got to any state.

No Race Conditions

State machines handle concurrent events predictably. No more "click happened before load finished" bugs.

Self-Documenting

The state machine definition IS the documentation. Visualize flows, understand behavior at a glance.

Resource Efficient

Only load resources needed for the current state. Faster load times and lower server usage.

Future-Proof

Easy to add new states and transitions. Extend the CMS without breaking existing functionality.

Where We Use State Machines

Authentication Flow

Login, logout, session refresh, MFA — all predictable state transitions.

Content Editing

Draft → Review → Published → Archived with clear transitions and permissions.

Media Upload

Idle → Uploading → Processing → Complete with proper error handling.

Form Validation

Pristine → Touched → Valid/Invalid with clear user feedback.
