# RefGraph.stronglyConnectedComponents

Get strongly connected components.

## Signatures

```ts
export declare const stronglyConnectedComponents: <N, E, Err, R>(ref: RefGraph<N, E, "directed", Err, R>) => RefSubject.Computed<Array<Array<Graph.NodeIndex>>, Err, R>;
```

## Why

Get strongly connected components. The operation remains attached to the RefSubject's versioned
state boundary.

## Ownership and lifetime

The strongly connected components view retains no independent state. An Effect read samples the
source once; Fx observation follows later pushes and its observing Scope owns subscription
cleanup.
