# routeEdges

[Source](https://github.com/konoe-akitoshi/shumoku/blob/main/libs/@shumoku/core/src/layout/route-edges.ts#L114)

Produce a \`ResolvedEdge\` for every link whose endpoints resolve to known ports. Links pointing at a missing port are dropped (matches the previous behaviour of libavoid-router). The function returns a Promise for backwards compatibility with the old WASM-backed router — every existing caller already awaits the result, and async-of-sync incurs zero cost. \`nodes\` is accepted but unused so the signature mirrors the historical libavoid-router API. Bezier edges read positions off \`ports\` directly via each \`ResolvedPort.absolutePosition\`.

```
routeEdges(nodes: Map<string, Node>, ports: Map<string, ResolvedPort>, links: readonly Link[], subgraphs?: Map<string, Subgraph>): Promise<Map<string, ResolvedEdge>>
```
