LlamaIndex.TS aims to be a lightweight, easy to use set of libraries to help you integrate large language models into your applications with your own data.
LlamaIndex.TS supports multiple JS environments, including:
- Node.js >= 20 ✅
- Deno ✅
- Bun ✅
- Nitro ✅
- Vercel Edge Runtime ✅ (with some limitations)
- Cloudflare Workers ✅ (with some limitations)
For now, browser support is limited due to the lack of support for AsyncLocalStorage-like APIs
- OpenAI LLms
- Anthropic LLms
- Groq LLMs
- Llama2, Llama3, Llama3.1 LLMs
- MistralAI LLMs
- Fireworks LLMs
- DeepSeek LLMs
- ReplicateAI LLMs
- TogetherAI LLMs
- HuggingFace LLms
- DeepInfra LLMs
- Gemini LLMs
npm install llamaindex
pnpm install llamaindex
yarn add llamaindex
See our official document: https://ts.llamaindex.ai/docs/llamaindex/getting_started/
When you are importing llamaindex
in a non-Node.js environment(such as Vercel Edge, Cloudflare Workers, etc.)
Some classes are not exported from top-level entry file.
The reason is that some classes are only compatible with Node.js runtime,(e.g. PDFReader
) which uses Node.js specific APIs(like fs
, child_process
, crypto
).
If you need any of those classes, you have to import them instead directly though their file path in the package.
Here's an example for importing the PineconeVectorStore
class:
import { PineconeVectorStore } from "llamaindex/storage/vectorStore/PineconeVectorStore";
As the PDFReader
is not working with the Edge runtime, here's how to use the SimpleDirectoryReader
with the LlamaParseReader
to load PDFs:
import { SimpleDirectoryReader } from "llamaindex/readers/SimpleDirectoryReader";
import { LlamaParseReader } from "llamaindex/readers/LlamaParseReader";
export const DATA_DIR = "./data";
export async function getDocuments() {
const reader = new SimpleDirectoryReader();
// Load PDFs using LlamaParseReader
return await reader.loadData({
directoryPath: DATA_DIR,
fileExtToReader: {
pdf: new LlamaParseReader({ resultType: "markdown" }),
},
});
}
Note: Reader classes have to be added explictly to the
fileExtToReader
map in the Edge version of theSimpleDirectoryReader
.

-
Document: A document represents a text file, PDF file or other contiguous piece of data.
-
Node: The basic data building block. Most commonly, these are parts of the document split into manageable pieces that are small enough to be fed into an embedding model and LLM.
-
Embedding: Embeddings are sets of floating point numbers which represent the data in a Node. By comparing the similarity of embeddings, we can derive an understanding of the similarity of two pieces of data. One use case is to compare the embedding of a question with the embeddings of our Nodes to see which Nodes may contain the data needed to answer that question. Because the default service context is OpenAI, the default embedding is
OpenAIEmbedding
. If using different models, say through Ollama, use this Embedding (see all here). -
Indices: Indices store the Nodes and the embeddings of those nodes. QueryEngines retrieve Nodes from these Indices using embedding similarity.
-
QueryEngine: Query engines are what generate the query you put in and give you back the result. Query engines generally combine a pre-built prompt with selected Nodes from your Index to give the LLM the context it needs to answer your query. To build a query engine from your Index (recommended), use the
asQueryEngine
method on your Index. See all query engines here. -
ChatEngine: A ChatEngine helps you build a chatbot that will interact with your Indices. See all chat engines here.
-
SimplePrompt: A simple standardized function call definition that takes in inputs and formats them in a template literal. SimplePrompts can be specialized using currying and combined using other SimplePrompt functions.
