# `ChartTransition`

Type, in `@jr2/orchestrator/src/chart.ts`. The signature of an export, or a type that it names, names this type. The [Authoring surface](../authoring-surface.md) page lists each export. This type is not an export of `@jr2/orchestrator`, so a workflow module does not import it by name.

```ts
type ChartTransition =
  | string
  | {
      target?: string | string[];
      guard?: ChartGuard;
      actions?: ChartAction[];
      reenter?: boolean;
      description?: string;
    };
```

A transition: a target alone, or the object form.
