Functions

`serializeGraph`

Freeze a live graph into the wire format.

Emits nodes and links in CANONICAL (id-sorted) order — the same discipline Established in fromAdapter. Determinism needs both halves: a seeded PRNG and a stable input order.

ts
function serializeGraph(nodes: NodeModel[], links: LinkModel[]): LayoutGraph

`serveLayout`

Serve layout requests on a port. This IS the worker's message loop — call it inside the worker script with self, or in a test with a fake port, or (see LayoutHost) on the inline side of a loopback pair.

ts
function serveLayout(port: LayoutServePort, deps: ServeLayoutDeps = {}): void

`toElkPortSide`

ts
function toElkPortSide(side: PortSide): ElkPortSide

`translateOptions`

One vocabulary in, each engine's dialect out.

The adapters disagree about names for the same concept — dagre says rankdir, nodesep, ranksep; ELK says elk.direction with words instead of letters.

Reusing this is what stops the nested path from quietly forking the options schema.

ts
function translateOptions(
  engine: string,
  options: UnifiedLayoutOptions
): Partial<LayoutOptions>

`treeLayout`

Tree layout over one connected component.

Component packing (see component-packing.ts) is what turns this into a FOREST layout: each tree is laid out here, alone, and the boxes are packed afterwards. That division is why a five-tree forest comes out as five tidy trees rather than the pile dagre produces.

ts
function treeLayout(
  nodes: NodeModel[],
  links: LinkModel[],
  options: TreeLayoutOptions = {}
): LayoutResult
