Get your key by logging in to the vectorview dashboard 
import Vectorview from "vectorview";
const vv = new Vectorview(key)
vv.event(query, docsWithScore)

​
Example

import { FaissStore } from "langchain/vectorstores/faiss";
import { OpenAIEmbeddings } from "langchain/embeddings/openai";
import { TokenTextSplitter } from "langchain/text_splitter";
import Vectorview from "vectorview";

// Setup
const vv = new Vectorview(key);

//  Do semantic search
const text = await fs.readFile('./text.txt', 'utf8'); 
const splitter = new TokenTextSplitter({ 
  chunkSize: 40, 
  chunkOverlap: 0,
});
const docs = await splitter.createDocuments([text]);
const vectorStore = await FaissStore.fromDocuments(docs, new OpenAIEmbeddings()); 

const query = "What did the president say about Ketanji Brown Jackson";
const docsWithScore = await vectorStore.similaritySearchWithScore(query, 3);

// Log vv event
vv.event(query, docsWithScore)

​
Advanced Use

​
Query metadata

Assign custom metadata to an event() by passing a dict as the third argument. 
vv.event(query, docsWithScore, {"foo": "bar"})

​
Document metadata

Documents in vectorview are langchain Documents which has a metadata field. Any metadata added will show up in your vectorview dashboard. 
docsWithScore[0][0].metadata = {"foo": "bar"}
vv.event(query, docsWithScore)

​
Custom document id

Vectorview assigns an id to each document used in an event(). To assign a custom id, add an id field in the Document’s metadata. 
docsWithScore[0][0].metadata = {"id": new_id}
vv.event(query, docsWithScore)
