Getting started

Chroma needs to be running in order for this client to talk to it. Please see the 🧪 Usage Guide to learn how to quickly stand this up.

Small example

import { ChromaClient } from "chromadb";
const chroma = new ChromaClient({ path: "http://localhost:8000" });
const collection = await chroma.createCollection({ name: "test-from-js" });
for (let i = 0; i < 20; i++) {
  await collection.add({
    ids: ["test-id-" + i.toString()],
    embeddings, [1, 2, 3, 4, 5],
    documents: ["test"],
  });
}
const queryData = await collection.query({
  queryEmbeddings: [1, 2, 3, 4, 5],
  queryTexts: ["test"],
});
