Graph Traversal

// BFS neighbourhood — center chunk + reachable neighbours within depth hops
const neighborhood: GraphNeighborhood = await indexer.getNeighborhood(chunkId, {
  depth?: number,                          // default: 1
  relationTypes?: RelationshipType[],      // default: all
  limit?: number,                          // max neighbours; default: 20
});


// Call graph
const callers: CodeChunk[] = await indexer.getCallers(chunkId);
const callees: CodeChunk[] = await indexer.getCallees(chunkId);


// Import graph
const deps: CodeChunk[]       = await indexer.getDependencies('src/auth.ts');
const dependents: CodeChunk[] = await indexer.getDependents('src/auth.ts');


// Inheritance
const implementors: CodeChunk[] = await indexer.getImplementors(chunkId);
const superTypes:   CodeChunk[] = await indexer.getSuperTypes(chunkId);


// Raw edge access
const outgoing: GraphEdge[] = await indexer.getEdgesFrom(chunkId, types?);
const incoming: GraphEdge[] = await indexer.getEdgesTo(chunkId, types?);
