Methods

add()

add(embeddingResults): Promise<string[]>

Adds vector record(s) to the table.

Parameters

• embeddingResults: BaseNode <Metadata>[]

The Nodes to be inserted, optionally including metadata tuples.

client()

client(): Promise<Pinecone>

Connects to the Pinecone account specified in environment vars. This method also checks and creates the named index if not found.

Returns

Promise<Pinecone>

Pinecone client, or the error encountered while connecting/setting up.
