An index is the basic container and organization for your data. LlamaIndex.TS supports two indexes:

  • VectorStoreIndex - will send the top-k Nodes to the LLM when generating a response. The default top-k is 2.
  • SummaryIndex - will send every Node in the index to the LLM in order to generate a response
import { Document, VectorStoreIndex } from "llamaindex";

const document = new Document({ text: "test" });

const index = await VectorStoreIndex.fromDocuments([document]);
