## Structure
LlamaIndex.TS uses pnpm monorepo.
This is a monorepo built with Turborepo
We recommend you to understand the basics of Node.js, TypeScript, pnpm, and of course, LLM before contributing.
Right now there are two packages of importance:
There are some important folders in the repository:
packages/core which is the main NPM library llamaindex
- `packages/*`: Contains the source code of the packages. Each package is a separate npm package.
- `llamaindex`: The starter package for LlamaIndex.TS, which contains the all sub-packages.
- `core`: The core package of LlamaIndex.TS, which contains the abstract classes and interfaces. It is designed for
all JS runtime environments.
- `env`: The environment package of LlamaIndex.TS, which contains the environment-specific classes and interfaces. It
includes compatibility layers for Node.js, Deno, Vercel Edge Runtime, Cloudflare Workers...
- `apps/*`: The applications based on LlamaIndex.TS.
- `next`: Our documentation website based on Next.js.
- `examples`: The code examples of LlamaIndex.TS using Node.js.
examples is where the demo code lives
### Turborepo docs
You can checkout how Turborepo works using the default [README-turborepo.md](/README-turborepo.md)
## Getting Started
Make sure you have Node.js LIS (Long-term Support) installed. You can check your Node.js version by running:
Install NodeJS. Preferably v18 using nvm or n.
Inside the LlamaIndexTS directory:
```shell
node -v
# v20.x.x
```
### Use pnpm
```shell
corepack enable
```
### Install dependencies
```shell
npm i -g pnpm ts-node
pnpm install
```
### Build the packages
Note: we use pnpm in this repo, which has a lot of the same functionality and CLI options as npm but it does do some things better in a monorepo, like centralizing dependencies and caching.
```shell
# Build all packages
turbo build --filter "./packages/*"
PNPM's has documentation on its [workspace feature](https://pnpm.io/workspaces) and Turborepo had some [useful documentation also](https://turbo.build/repo/docs/core-concepts/monorepos/running-tasks).
### Running Typescript
When we publish to NPM we will have a tsc compiled version of the library in JS. For now, the easiest thing to do is use ts-node.
### Test cases
To run them, run
```
pnpm run test
```
To write new test cases write them in [packages/core/src/tests](/packages/core/src/tests)
We use Jest https://jestjs.io/ to write our test cases. Jest comes with a bunch of built in assertions using the expect function: https://jestjs.io/docs/expect
### Demo applications
There is an existing ["example"](/examples/README.md) demos folder with mainly NodeJS scripts. Feel free to add additional demos to that folder. If you would like to try out your changes in the core package with a new demo, you need to run the build command in the README.
You can create new demo applications in the apps folder. Just run pnpm init in the folder after you create it to create its own package.json
### Installing packages
To install packages for a specific package or demo application, run
```
pnpm add [NPM Package] --filter [package or application i.e. core or docs]
```
To install packages for every package or application run
```
pnpm add -w [NPM Package]
```
### Docs
See the [docs](./apps/next/README.md) for more information.
To contribute to the docs, go to the docs website folder and run the Docusaurus instance.
## Changeset
We use [changesets](https://github.com/changesets/changesets) for managing versions and changelogs. To create a new
changeset, run in the root folder:
```
pnpm changeset
```bash
cd apps/docs
pnpm install
pnpm start
```
Please send a descriptive changeset for each PR.
That should start a webserver which will serve the docs on https://localhost:3000
## Publishing (maintainers only)
Any changes you make should be reflected in the browser. If you need to regenerate the API docs and find that your TSDoc isn't getting the updates, feel free to remove apps/docs/api. It will automatically regenerate itself when you run pnpm start again.
The [Release Github Action](.github/workflows/release.yml) is automatically generating and updating a
PR called "Release {version}".
## Publishing
This PR will update the `package.json` and `CHANGELOG.md` files of each package according to
the current changesets in the [.changeset](.changeset) folder.
To publish a new version of the library, run
If this PR is merged it will automatically add version tags to the repository and publish the updated packages to NPM.
```shell
pnpm new-llamaindex
pnpm new-create-llama
pnpm release
git push # push to the main branch
git push --tags
```

# Turborepo starter
This is an official starter Turborepo.
## Using this example
Run the following command:
```sh
npx create-turbo@latest
```
## What's inside?
This Turborepo includes the following packages/apps:
### Apps and Packages
- `docs`: a [Next.js](https://nextjs.org/) app
- `web`: another [Next.js](https://nextjs.org/) app
- `ui`: a stub React component library shared by both `web` and `docs` applications
- `eslint-config-custom`: `eslint` configurations (includes `eslint-config-next` and `eslint-config-prettier`)
- `tsconfig`: `tsconfig.json`s used throughout the monorepo
Each package/app is 100% [TypeScript](https://www.typescriptlang.org/).
### Utilities
This Turborepo has some additional tools already setup for you:
- [TypeScript](https://www.typescriptlang.org/) for static type checking
- [ESLint](https://eslint.org/) for code linting
- [Prettier](https://prettier.io) for code formatting
### Build
To build all apps and packages, run the following command:
```
cd my-turborepo
pnpm build
```
### Develop
To develop all apps and packages, run the following command:
```
cd my-turborepo
pnpm dev
```
### Remote Caching
Turborepo can use a technique known as [Remote Caching](https://turbo.build/repo/docs/core-concepts/remote-caching) to share cache artifacts across machines, enabling you to share build caches with your team and CI/CD pipelines.
By default, Turborepo will cache locally. To enable Remote Caching you will need an account with Vercel. If you don't have an account you can [create one](https://vercel.com/signup), then enter the following commands:
```
cd my-turborepo
npx turbo login
```
This will authenticate the Turborepo CLI with your [Vercel account](https://vercel.com/docs/concepts/personal-accounts/overview).
Next, you can link your Turborepo to your Remote Cache by running the following command from the root of your Turborepo:
```
npx turbo link
```

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.
## Compatibility
## Getting started with an example:
### Multiple JS Environment Support
LlamaIndex.TS requires Node v18 or higher. You can download it from https://nodejs.org or use https://nvm.sh (our preferred option).
LlamaIndex.TS supports multiple JS environments, including:
In a new folder:
- 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](https://github.com/tc39/proposal-async-context)
### Supported LLMs:
- 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

```ts
// example.ts
import fs from "fs/promises";
import { Document, VectorStoreIndex } from "llamaindex";
### Adding provider packages
async function main() {
// Load essay from abramov.txt in Node
const essay = await fs.readFile(
"node_modules/llamaindex/examples/abramov.txt",
"utf-8",
);
In most cases, you'll also need to install provider packages to use LlamaIndexTS. These are for adding AI models, file readers for ingestion or storing documents, e.g. in vector databases.
// Create Document object with essay
const document = new Document({ text: essay });
For example, to use the OpenAI LLM, you would install the following package:
// Split text and create embeddings. Store them in a VectorStoreIndex
const index = await VectorStoreIndex.fromDocuments([document]);
```shell
npm install @llamaindex/openai
pnpm install @llamaindex/openai
yarn add @llamaindex/openai
// Query the index
const queryEngine = index.asQueryEngine();
const response = await queryEngine.query({
query: "What did the author do in college?",
});
// Output response
console.log(response.toString());
}
main();
```
Then you can run it using
```bash
pnpm dlx ts-node example.ts
```

- [Document](/packages/core/src/Node.ts): A document represents a text file, PDF file or other contiguous piece of data.
- [Node](/packages/llamaindex/src/Node.ts): 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.
- [Node](/packages/core/src/Node.ts): 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](/packages/llamaindex/src/embeddings/OpenAIEmbedding.ts): 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](/packages/llamaindex/src/embeddings/OllamaEmbedding.ts) (see all [here](/packages/llamaindex/src/embeddings)).

- [QueryEngine](/packages/llamaindex/src/engines/query/RetrieverQueryEngine.ts): 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`](/packages/llamaindex/src/indices/BaseIndex.ts) method on your Index.

## Note: NextJS:
If you're using NextJS App Router, you'll need to use the NodeJS runtime (default) and add the following config to your next.config.js to have it use imports/exports in the same way Node does.
```js
export const runtime = "nodejs"; // default
```
```js
// next.config.js
/** @type {import('next').NextConfig} */
const nextConfig = {
experimental: {
serverComponentsExternalPackages: ["pdf2json"],
},
webpack: (config) => {
config.resolve.alias = {
...config.resolve.alias,
sharp$: false,
"onnxruntime-node$": false,
};
return config;
},
};
module.exports = nextConfig;
```
## Supported LLMs:
- OpenAI GPT-3.5-turbo and GPT-4
- Anthropic Claude Instant and Claude 2
- Llama2 Chat LLMs (70B, 13B, and 7B parameters)
- MistralAI Chat LLMs

# Concepts
LlamaIndex.TS helps you build LLM-powered applications (e.g. Q&A, chatbot) over custom data.
In this high-level concepts guide, you will learn:
- how an LLM can answer questions using your own data.
- key concepts and modules in LlamaIndex.TS for composing your own query pipeline.
## Answering Questions Across Your Data
LlamaIndex uses a two stage method when using an LLM with your data:
1. **indexing stage**: preparing a knowledge base, and
2. **querying stage**: retrieving relevant context from the knowledge to assist the LLM in responding to a question
![](../_static/concepts/rag.jpg)
This process is also known as Retrieval Augmented Generation (RAG).
LlamaIndex.TS provides the essential toolkit for making both steps super easy.
Let's explore each stage in detail.
### Indexing Stage
LlamaIndex.TS help you prepare the knowledge base with a suite of data connectors and indexes.
![](../_static/concepts/indexing.jpg)
[**Data Loaders**](../modules/data_loader.md):
A data connector (i.e. `Reader`) ingest data from different data sources and data formats into a simple `Document` representation (text and simple metadata).
[**Documents / Nodes**](../modules/documents_and_nodes/index.md): A `Document` is a generic container around any data source - for instance, a PDF, an API output, or retrieved data from a database. A `Node` is the atomic unit of data in LlamaIndex and represents a "chunk" of a source `Document`. It's a rich representation that includes metadata and relationships (to other nodes) to enable accurate and expressive retrieval operations.
[**Data Indexes**](../modules/data_index.md):
Once you've ingested your data, LlamaIndex helps you index data into a format that's easy to retrieve.
Under the hood, LlamaIndex parses the raw documents into intermediate representations, calculates vector embeddings, and stores your data in-memory or to disk.
### Querying Stage
In the querying stage, the query pipeline retrieves the most relevant context given a user query,
and pass that to the LLM (along with the query) to synthesize a response.
This gives the LLM up-to-date knowledge that is not in its original training data,
(also reducing hallucination).
The key challenge in the querying stage is retrieval, orchestration, and reasoning over (potentially many) knowledge bases.
LlamaIndex provides composable modules that help you build and integrate RAG pipelines for Q&A (query engine), chatbot (chat engine), or as part of an agent.
These building blocks can be customized to reflect ranking preferences, as well as composed to reason over multiple knowledge bases in a structured way.
![](../_static/concepts/querying.jpg)
#### Building Blocks
[**Retrievers**](../modules/retriever.md):
A retriever defines how to efficiently retrieve relevant context from a knowledge base (i.e. index) when given a query.
The specific retrieval logic differs for difference indices, the most popular being dense retrieval against a vector index.
[**Response Synthesizers**](../modules/response_synthesizer.md):
A response synthesizer generates a response from an LLM, using a user query and a given set of retrieved text chunks.
#### Pipelines
[**Query Engines**](../modules/query_engines):
A query engine is an end-to-end pipeline that allow you to ask question over your data.
It takes in a natural language query, and returns a response, along with reference context retrieved and passed to the LLM.
[**Chat Engines**](../modules/chat_engine.md):
A chat engine is an end-to-end pipeline for having a conversation with your data
(multiple back-and-forth instead of a single question & answer).

## Using create-llama
The easiest way to get started with LlamaIndex is by using `create-llama`. This CLI tool enables you to quickly start building a new LlamaIndex application, with everything set up for you.
Just run
<Tabs>
<TabItem value="1" label="npm" default>
```bash
npx create-llama@latest
```

to get started. Once your app is generated, run
```bash npm2yarn
npm run dev
```
to start the development server. You can then visit [http://localhost:3000](http://localhost:3000) to see your app
## Installation from NPM
```bash npm2yarn
npm install llamaindex
```
### Environment variables
Our examples use OpenAI by default. You'll need to set up your Open AI key like so:
```bash
export OPENAI_API_KEY="sk-......" # Replace with your key from https://platform.openai.com/account/api-keys
```
If you want to have it automatically loaded every time, add it to your `.zshrc/.bashrc`.
WARNING: do not check in your OpenAI key into version control.

# Starter Tutorial
Once you have [installed LlamaIndex.TS using NPM](installation) and set up your OpenAI key, you're ready to start your first app:
In a new folder:
```bash npm2yarn
npm install typescript
npm install @types/node
npx tsc --init # if needed
```
Create the file `example.ts`. This code will load some example data, create a document, index it (which creates embeddings using OpenAI), and then creates query engine to answer questions about the data.
```ts
// example.ts
import fs from "fs/promises";
import { Document, VectorStoreIndex } from "llamaindex";
async function main() {
// Load essay from abramov.txt in Node
const essay = await fs.readFile(
"node_modules/llamaindex/examples/abramov.txt",
"utf-8",
);
// Create Document object with essay
const document = new Document({ text: essay });
// Split text and create embeddings. Store them in a VectorStoreIndex
const index = await VectorStoreIndex.fromDocuments([document]);
// Query the index
const queryEngine = index.asQueryEngine();
const response = await queryEngine.query({
query: "What did the author do in college?",
});
// Output response
console.log(response.toString());
}
main();
```
Then you can run it using
```bash
npx ts-node example.ts
```

# What is LlamaIndex.TS?
LlamaIndex.TS is a data framework for LLM applications to ingest, structure, and access private or domain-specific data. While a python package is also available (see [here](https://docs.llamaindex.ai/en/stable/)), LlamaIndex.TS offers core features in a simple package, optimized for usage with TypeScript.
## 🚀 Why LlamaIndex.TS?
At their core, LLMs offer a natural language interface between humans and inferred data. Widely available models come pre-trained on huge amounts of publicly available data, from Wikipedia and mailing lists to textbooks and source code.
Applications built on top of LLMs often require augmenting these models with private or domain-specific data. Unfortunately, that data can be distributed across siloed applications and data stores. It's behind APIs, in SQL databases, or trapped in PDFs and slide decks.
That's where **LlamaIndex.TS** comes in.
## 🦙 How can LlamaIndex.TS help?
LlamaIndex.TS provides the following tools:
- **Data loading** ingest your existing `.txt`, `.pdf`, `.csv`, `.md` and `.docx` data directly
- **Data indexes** structure your data in intermediate representations that are easy and performant for LLMs to consume.
- **Engines** provide natural language access to your data. For example:
- Query engines are powerful retrieval interfaces for knowledge-augmented output.
- Chat engines are conversational interfaces for multi-message, "back and forth" interactions with your data.
## 👨‍👩‍👧‍👦 Who is LlamaIndex for?
LlamaIndex.TS provides a core set of tools, essential for anyone building LLM apps with JavaScript and TypeScript.
Our high-level API allows beginner users to use LlamaIndex.TS to ingest and query their data.
For more complex applications, our lower-level APIs allow advanced users to customize and extend any module—data connectors, indices, retrievers, and query engines, to fit their needs.
## Getting Started
`npm install llamaindex`
Our documentation includes [Installation Instructions](./getting_started/installation.mdx) and a [Starter Tutorial](./getting_started/starter.md) to build your first application.
Once you're up and running, [High-Level Concepts](./getting_started/concepts.md) has an overview of LlamaIndex's modular architecture. For more hands-on practical examples, look through our Examples section on the sidebar.

# Agents
An “agent” is an automated reasoning and decision engine. It takes in a user input/query and can make internal decisions for executing that query in order to return the correct result. The key agent components can include, but are not limited to:
- Breaking down a complex question into smaller ones
- Choosing an external Tool to use + coming up with parameters for calling the Tool
- Planning out a set of tasks
- Storing previously completed tasks in a memory module
## Getting Started
LlamaIndex.TS comes with a few built-in agents, but you can also create your own. The built-in agents include:

# OpenAI Agent
OpenAI API that supports function calling, its never been easier to build your own agent!
In this notebook tutorial, we showcase how to write your own OpenAI agent
## Setup
First, you need to install the `llamaindex` package. You can do this by running the following command in your terminal:
```bash
pnpm i llamaindex
```
Then we can define a function to sum two numbers and another function to divide two numbers.
```ts
function sumNumbers({ a, b }: { a: number; b: number }): number {
return a + b;
}
// Define a function to divide two numbers
function divideNumbers({ a, b }: { a: number; b: number }): number {
return a / b;
}
```
## Create a function tool
Now we can create a function tool from the sum function and another function tool from the divide function.
For the parameters of the sum function, we can define a JSON schema.
### JSON Schema
```ts
const sumJSON = {
type: "object",
properties: {
a: {
type: "number",
description: "The first number",
},
b: {
type: "number",
description: "The second number",
},
},
required: ["a", "b"],
};
const divideJSON = {
type: "object",
properties: {
a: {
type: "number",
description: "The dividend a to divide",
},
b: {
type: "number",
description: "The divisor b to divide by",
},
},
required: ["a", "b"],
};
const sumFunctionTool = new FunctionTool(sumNumbers, {
name: "sumNumbers",
description: "Use this function to sum two numbers",
parameters: sumJSON,
});
const divideFunctionTool = new FunctionTool(divideNumbers, {
name: "divideNumbers",
description: "Use this function to divide two numbers",
parameters: divideJSON,
});
```
## Create an OpenAIAgent
Now we can create an OpenAIAgent with the function tools.
```ts
const worker = new OpenAIAgent({
tools: [sumFunctionTool, divideFunctionTool],
verbose: true,
});
```
## Chat with the agent
Now we can chat with the agent.
```ts
const response = await worker.chat({
message: "How much is 5 + 5? then divide by 2",
});
console.log(String(response));
```
## Full code
```ts
import { FunctionTool, OpenAIAgent } from "llamaindex";
// Define a function to sum two numbers
function sumNumbers({ a, b }: { a: number; b: number }): number {
return a + b;
}
// Define a function to divide two numbers
function divideNumbers({ a, b }: { a: number; b: number }): number {
return a / b;
}
// Define the parameters of the sum function as a JSON schema
const sumJSON = {
type: "object",
properties: {
a: {
type: "number",
description: "The first number",
},
b: {
type: "number",
description: "The second number",
},
},
required: ["a", "b"],
};
// Define the parameters of the divide function as a JSON schema
const divideJSON = {
type: "object",
properties: {
a: {
type: "number",
description: "The argument a to divide",
},
b: {
type: "number",
description: "The argument b to divide",
},
},
required: ["a", "b"],
};
async function main() {
// Create a function tool from the sum function
const sumFunctionTool = new FunctionTool(sumNumbers, {
name: "sumNumbers",
description: "Use this function to sum two numbers",
parameters: sumJSON,
});
// Create a function tool from the divide function
const divideFunctionTool = new FunctionTool(divideNumbers, {

description: "Use this function to divide two numbers",
parameters: divideJSON,
});
// Create an OpenAIAgent with the function tools
const agent = new OpenAIAgent({
tools: [sumFunctionTool, divideFunctionTool],
verbose: true,
});
// Chat with the agent
const response = await agent.chat({
message: "How much is 5 + 5? then divide by 2",

# OpenAI Agent + QueryEngineTool
QueryEngineTool is a tool that allows you to query a vector index. In this example, we will create a vector index from a set of documents and then create a QueryEngineTool from the vector index. We will then create an OpenAIAgent with the QueryEngineTool and chat with the agent.
## Setup
First, you need to install the `llamaindex` package. You can do this by running the following command in your terminal:
```bash
pnpm i llamaindex
```
Then you can import the necessary classes and functions.
```ts
import {
OpenAIAgent,
SimpleDirectoryReader,
VectorStoreIndex,
QueryEngineTool,
} from "llamaindex";
```
## Create a vector index
Now we can create a vector index from a set of documents.
```ts
// Load the documents
const documents = await new SimpleDirectoryReader().loadData({
directoryPath: "node_modules/llamaindex/examples/",
});
// Create a vector index from the documents
const vectorIndex = await VectorStoreIndex.fromDocuments(documents);
```
## Create a QueryEngineTool
Now we can create a QueryEngineTool from the vector index.
```ts
// Create a query engine from the vector index
const abramovQueryEngine = vectorIndex.asQueryEngine();
// Create a QueryEngineTool with the query engine
const queryEngineTool = new QueryEngineTool({
queryEngine: abramovQueryEngine,
metadata: {
name: "abramov_query_engine",
description: "A query engine for the Abramov documents",
},
});
```
## Create an OpenAIAgent
```ts
// Create an OpenAIAgent with the query engine tool tools
const agent = new OpenAIAgent({
tools: [queryEngineTool],
verbose: true,
});
```
## Chat with the agent
Now we can chat with the agent.
```ts
const response = await agent.chat({
message: "What was his salary?",
});
console.log(String(response));
```
## Full code
```ts
import {
OpenAIAgent,
SimpleDirectoryReader,
VectorStoreIndex,
QueryEngineTool,
} from "llamaindex";
async function main() {
// Load the documents
const documents = await new SimpleDirectoryReader().loadData({

# ChatEngine
The chat engine is a quick and simple way to chat with the data in your index.
```typescript
const retriever = index.asRetriever();
const chatEngine = new ContextChatEngine({ retriever });
// start chatting
const response = await chatEngine.chat({ message: query });
```
The `chat` function also supports streaming, just add `stream: true` as an option:
```typescript
const stream = await chatEngine.chat({ message: query, stream: true });
for await (const chunk of stream) {
process.stdout.write(chunk.response);
}
```

# Index
An index is the basic container and organization for your data. LlamaIndex.TS supports two indexes:
- `VectorStoreIndex` - will send the top-k `Node`s 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
```typescript
import { Document, VectorStoreIndex } from "llamaindex";
const document = new Document({ text: "test" });
const index = await VectorStoreIndex.fromDocuments([document]);

LlamaIndex.TS supports easy loading of files from folders using the `SimpleDirectoryReader` class.
It is a simple reader that reads all files from a directory and its subdirectories.
<CodeBlock language="ts">{CodeSource}</CodeBlock>
Currently, it supports reading `.csv`, `.docx`, `.html`, `.md` and `.pdf` files,
but support for other file types is planned.
Also, you can provide a `defaultReader` as a fallback for files with unsupported extensions.
Or pass new readers for `fileExtToReader` to support more file types.

`Document`s and `Node`s are the basic building blocks of any index. While the API for these objects is similar, `Document` objects represent entire files, while `Node`s are smaller pieces of that original document, that are suitable for an LLM and Q&A.

# Metadata Extraction Usage Pattern
You can use LLMs to automate metadata extraction with our `Metadata Extractor` modules.
Our metadata extractor modules include the following "feature extractors":
- `SummaryExtractor` - automatically extracts a summary over a set of Nodes
- `QuestionsAnsweredExtractor` - extracts a set of questions that each Node can answer
- `TitleExtractor` - extracts a title over the context of each Node by document and combine them
- `KeywordExtractor` - extracts keywords over the context of each Node
Then you can chain the `Metadata Extractors` with the `IngestionPipeline` to extract metadata from a set of documents.
```ts
import {
IngestionPipeline,
TitleExtractor,
QuestionsAnsweredExtractor,
Document,
OpenAI,
} from "llamaindex";
async function main() {
const pipeline = new IngestionPipeline({
transformations: [
new TitleExtractor(),
new QuestionsAnsweredExtractor({
questions: 5,
}),
],
});
const nodes = await pipeline.run({
documents: [
new Document({ text: "I am 10 years old. John is 20 years old." }),
],
});
for (const node of nodes) {
console.log(node.metadata);
}
}
main().then(() => console.log("done"));

# Ingestion Pipeline
An `IngestionPipeline` uses a concept of `Transformations` that are applied to input data.
These `Transformations` are applied to your input data, and the resulting nodes are either returned or inserted into a vector database (if given).
## Usage Pattern
The simplest usage is to instantiate an IngestionPipeline like so:
```ts
import fs from "node:fs/promises";
import {
Document,
IngestionPipeline,
MetadataMode,
OpenAIEmbedding,
TitleExtractor,
SimpleNodeParser,
} from "llamaindex";
async function main() {
// Load essay from abramov.txt in Node
const path = "node_modules/llamaindex/examples/abramov.txt";
const essay = await fs.readFile(path, "utf-8");
// Create Document object with essay
const document = new Document({ text: essay, id_: path });
const pipeline = new IngestionPipeline({
transformations: [
new SimpleNodeParser({ chunkSize: 1024, chunkOverlap: 20 }),
new TitleExtractor(),
new OpenAIEmbedding(),
],
});
// run the pipeline
const nodes = await pipeline.run({ documents: [document] });
// print out the result of the pipeline run
for (const node of nodes) {
console.log(node.getContent(MetadataMode.NONE));
}
}
main().catch(console.error);
```
## Connecting to Vector Databases
When running an ingestion pipeline, you can also chose to automatically insert the resulting nodes into a remote vector store.
Then, you can construct an index from that vector store later on.
```ts
import fs from "node:fs/promises";
import {
Document,
IngestionPipeline,
MetadataMode,
OpenAIEmbedding,
TitleExtractor,
SimpleNodeParser,
QdrantVectorStore,
VectorStoreIndex,
} from "llamaindex";
async function main() {
// Load essay from abramov.txt in Node
const path = "node_modules/llamaindex/examples/abramov.txt";
const essay = await fs.readFile(path, "utf-8");
const vectorStore = new QdrantVectorStore({
host: "http://localhost:6333",
});
// Create Document object with essay
const document = new Document({ text: essay, id_: path });
const pipeline = new IngestionPipeline({
transformations: [
new SimpleNodeParser({ chunkSize: 1024, chunkOverlap: 20 }),
new TitleExtractor(),
new OpenAIEmbedding(),
],
vectorStore,
});
// run the pipeline
const nodes = await pipeline.run({ documents: [document] });
// create an index
const index = VectorStoreIndex.fromVectorStore(vectorStore);
}

# Transformations
A transformation is something that takes a list of nodes as an input, and returns a list of nodes. Each component that implements the Transformatio class has both a `transform` definition responsible for transforming the nodes
Currently, the following components are Transformation objects:
- [SimpleNodeParser](../api/classes/SimpleNodeParser.md)
- [MetadataExtractor](../documents_and_nodes/metadata_extraction.md)
- Embeddings
## Usage Pattern
While transformations are best used with with an IngestionPipeline, they can also be used directly.
```ts
import { SimpleNodeParser, TitleExtractor, Document } from "llamaindex";
async function main() {
let nodes = new SimpleNodeParser().getNodesFromDocuments([
new Document({ text: "I am 10 years old. John is 20 years old." }),
]);
const titleExtractor = new TitleExtractor();
nodes = await titleExtractor.transform(nodes);
for (const node of nodes) {
console.log(node.getContent(MetadataMode.NONE));
}
}
main().catch(console.error);
```
## Custom Transformations
You can implement any transformation yourself by implementing the `TransformerComponent`.
The following custom transformation will remove any special characters or punctutaion in text.
```ts
import { TransformerComponent, Node } from "llamaindex";
class RemoveSpecialCharacters extends TransformerComponent {
async transform(nodes: Node[]): Promise<Node[]> {
for (const node of nodes) {
node.text = node.text.replace(/[^\w\s]/gi, "");
}
return nodes;
}
}
```
These can then be used directly or in any IngestionPipeline.
```ts
import { IngestionPipeline, Document } from "llamaindex";
async function main() {
const pipeline = new IngestionPipeline({
transformations: [new RemoveSpecialCharacters()],
});
const nodes = await pipeline.run({
documents: [
new Document({ text: "I am 10 years old. John is 20 years old." }),
],
});
for (const node of nodes) {
console.log(node.getContent(MetadataMode.NONE));
}
}
main().catch(console.error);

# NodeParser
The `NodeParser` in LlamaIndex is responsible for splitting `Document` objects into more manageable `Node` objects. When you call `.fromDocuments()`, the `NodeParser` from the `ServiceContext` is used to do this automatically for you. Alternatively, you can use it to split documents ahead of time.

For this example, we will use a single document. In a real-world scenario, you would have multiple documents to index.
```ts
const document = new Document({ text: essay, id_: "essay" });
const serviceContext = serviceContextFromDefaults({
llm: new OpenAI({ model: "gpt-3.5-turbo", temperature: 0.1 }),
});
const index = await VectorStoreIndex.fromDocuments([document], {
serviceContext,
});
```
## Increase similarity topK to retrieve more results
The default value for `similarityTopK` is 2. This means that only the most similar document will be returned. To retrieve more results, you can increase the value of `similarityTopK`.
```ts
const retriever = index.asRetriever();
retriever.similarityTopK = 5;
```
## Create a new instance of the CohereRerank class
Then you can create a new instance of the `CohereRerank` class and pass in your API key and the number of results you want to return.
```ts
const nodePostprocessor = new CohereRerank({
apiKey: "<COHERE_API_KEY>",
topN: 4,
});
```
## Create a query engine with the retriever and node postprocessor
```ts
const queryEngine = index.asQueryEngine({
retriever,
nodePostprocessors: [nodePostprocessor],
});
// log the response
const response = await queryEngine.query("Where did the author grown up?");
```

# Node Postprocessors
## Concept
Node postprocessors are a set of modules that take a set of nodes, and apply some kind of transformation or filtering before returning them.
In LlamaIndex, node postprocessors are most commonly applied within a query engine, after the node retrieval step and before the response synthesis step.
LlamaIndex offers several node postprocessors for immediate use, while also providing a simple API for adding your own custom postprocessors.
## Usage Pattern
An example of using a node postprocessors is below:
```ts
import {
Node,
NodeWithScore,
SimilarityPostprocessor,
CohereRerank,
} from "llamaindex";
const nodes: NodeWithScore[] = [
{
node: new TextNode({ text: "hello world" }),
score: 0.8,
},
{
node: new TextNode({ text: "LlamaIndex is the best" }),
score: 0.6,
},
];
// similarity postprocessor: filter nodes below 0.75 similarity score
const processor = new SimilarityPostprocessor({
similarityCutoff: 0.7,
});
const filteredNodes = processor.postprocessNodes(nodes);
// cohere rerank: rerank nodes given query using trained model
const reranker = new CohereRerank({
apiKey: "<COHERE_API_KEY>",
topN: 2,
});
const rerankedNodes = await reranker.postprocessNodes(nodes, "<user_query>");
console.log(filteredNodes, rerankedNodes);
```
Now you can use the `filteredNodes` and `rerankedNodes` in your application.
## Using Node Postprocessors in LlamaIndex
Most commonly, node-postprocessors will be used in a query engine, where they are applied to the nodes returned from a retriever, and before the response synthesis step.
### Using Node Postprocessors in a Query Engine
```ts
import { Node, NodeWithScore, SimilarityPostprocessor, CohereRerank } from "llamaindex";
const nodes: NodeWithScore[] = [
{
node: new TextNode({ text: "hello world" }),
score: 0.8,
},
{
node: new TextNode({ text: "LlamaIndex is the best" }),
score: 0.6,
}
];
// cohere rerank: rerank nodes given query using trained model
const reranker = new CohereRerank({
apiKey: "<COHERE_API_KEY>,
topN: 2,
})
const document = new Document({ text: "essay", id_: "essay" });
const serviceContext = serviceContextFromDefaults({
llm: new OpenAI({ model: "gpt-3.5-turbo", temperature: 0.1 }),
});
const index = await VectorStoreIndex.fromDocuments([document], {
serviceContext,
});
const queryEngine = index.asQueryEngine({
nodePostprocessors: [processor, reranker],
});
// all node post-processors will be applied during each query
const response = await queryEngine.query("<user_query>");
```
### Using with retrieved nodes
```ts
import { SimilarityPostprocessor } from "llamaindex";
nodes = await index.asRetriever().retrieve("test query str");
const processor = new SimilarityPostprocessor({
similarityCutoff: 0.7,
});
const filteredNodes = processor.postprocessNodes(nodes);

# QueryEngine
A query engine wraps a `Retriever` and a `ResponseSynthesizer` into a pipeline, that will use the query string to fetech nodes and then send them to the LLM to generate a response.
```typescript
const queryEngine = index.asQueryEngine();
const response = await queryEngine.query({ query: "query string" });
```
The `query` function also supports streaming, just add `stream: true` as an option:
```typescript
const stream = await queryEngine.query({ query: "query string", stream: true });
for await (const chunk of stream) {
process.stdout.write(chunk.response);
}
```
## Sub Question Query Engine
The basic concept of the Sub Question Query Engine is that it splits a single query into multiple queries, gets an answer for each of those queries, and then combines those different answers into a single coherent response for the user. You can think of it as the "think this through step by step" prompt technique but iterating over your data sources!
### Getting Started
The easiest way to start trying the Sub Question Query Engine is running the subquestion.ts file in [examples](https://github.com/run-llama/LlamaIndexTS/blob/main/examples/subquestion.ts).
```bash
npx ts-node subquestion.ts
```
### Tools
SubQuestionQueryEngine is implemented with Tools. The basic idea of Tools is that they are executable options for the large language model. In this case, our SubQuestionQueryEngine relies on QueryEngineTool, which as you guessed it is a tool to run queries on a QueryEngine. This allows us to give the model an option to query different documents for different questions for example. You could also imagine that the SubQuestionQueryEngine could use a Tool that searches for something on the web or gets an answer using Wolfram Alpha.
You can learn more about Tools by taking a look at the LlamaIndex Python documentation https://gpt-index.readthedocs.io/en/latest/core_modules/agent_modules/tools/root.html

# Metadata Filtering
Metadata filtering is a way to filter the documents that are returned by a query based on the metadata associated with the documents. This is useful when you want to filter the documents based on some metadata that is not part of the document text.
You can also check our multi-tenancy blog post to see how metadata filtering can be used in a multi-tenant environment. [https://blog.llamaindex.ai/building-multi-tenancy-rag-system-with-llamaindex-0d6ab4e0c44b] (the article uses the Python version of LlamaIndex, but the concepts are the same).
## Setup
Firstly if you haven't already, you need to install the `llamaindex` package:
```bash
pnpm i llamaindex
```
Then you can import the necessary modules from `llamaindex`:
```ts
import {
ChromaVectorStore,
Document,
VectorStoreIndex,
storageContextFromDefaults,
} from "llamaindex";
const collectionName = "dog_colors";
```
## Creating documents with metadata
You can create documents with metadata using the `Document` class:
```ts
const docs = [
new Document({
text: "The dog is brown",
metadata: {
color: "brown",
dogId: "1",
},
}),
new Document({
text: "The dog is red",
metadata: {
color: "red",
dogId: "2",
},
}),
];
```
## Creating a ChromaDB vector store
You can create a `ChromaVectorStore` to store the documents:
```ts
const chromaVS = new ChromaVectorStore({ collectionName });
const serviceContext = await storageContextFromDefaults({
vectorStore: chromaVS,
});
const index = await VectorStoreIndex.fromDocuments(docs, {
storageContext: serviceContext,
});
```
## Querying the index with metadata filtering
Now you can query the index with metadata filtering using the `preFilters` option:
```ts
const queryEngine = index.asQueryEngine({
preFilters: {
filters: [
{
key: "dogId",
value: "2",
filterType: "ExactMatch",
},
],
},
});
const response = await queryEngine.query({
query: "What is the color of the dog?",
});
console.log(response.toString());
```
## Full Code
```ts
import {
ChromaVectorStore,
Document,
VectorStoreIndex,
storageContextFromDefaults,
} from "llamaindex";
const collectionName = "dog_colors";
async function main() {
try {
const docs = [
new Document({
text: "The dog is brown",
metadata: {
color: "brown",
dogId: "1",
},
}),
new Document({
text: "The dog is red",
metadata: {
color: "red",
dogId: "2",
},
}),
];
console.log("Creating ChromaDB vector store");
const chromaVS = new ChromaVectorStore({ collectionName });
const ctx = await storageContextFromDefaults({ vectorStore: chromaVS });
console.log("Embedding documents and adding to index");
const index = await VectorStoreIndex.fromDocuments(docs, {
storageContext: ctx,
});
console.log("Querying index");
const queryEngine = index.asQueryEngine({
preFilters: {
filters: [
{
key: "dogId",
value: "2",

});
const response = await queryEngine.query({

# Router Query Engine
In this tutorial, we define a custom router query engine that selects one out of several candidate query engines to execute a query.
## Setup
First, we need to install import the necessary modules from `llamaindex`:
```bash
pnpm i lamaindex
```
```ts
import {
OpenAI,
RouterQueryEngine,
SimpleDirectoryReader,
SimpleNodeParser,
SummaryIndex,
VectorStoreIndex,
serviceContextFromDefaults,
} from "llamaindex";
```
## Loading Data
Next, we need to load some data. We will use the `SimpleDirectoryReader` to load documents from a directory:
```ts
const documents = await new SimpleDirectoryReader().loadData({
directoryPath: "node_modules/llamaindex/examples",
});
```
## Service Context
Next, we need to define some basic rules and parse the documents into nodes. We will use the `SimpleNodeParser` to parse the documents into nodes and `ServiceContext` to define the rules (eg. LLM API key, chunk size, etc.):
```ts
const nodeParser = new SimpleNodeParser({
chunkSize: 1024,
});
const serviceContext = serviceContextFromDefaults({
nodeParser,
llm: new OpenAI(),
});
```
## Creating Indices
Next, we need to create some indices. We will create a `VectorStoreIndex` and a `SummaryIndex`:
```ts
const vectorIndex = await VectorStoreIndex.fromDocuments(documents, {
serviceContext,
});
const summaryIndex = await SummaryIndex.fromDocuments(documents, {
serviceContext,
});
```
## Creating Query Engines
Next, we need to create some query engines. We will create a `VectorStoreQueryEngine` and a `SummaryQueryEngine`:
```ts
const vectorQueryEngine = vectorIndex.asQueryEngine();
const summaryQueryEngine = summaryIndex.asQueryEngine();
```
## Creating a Router Query Engine
Next, we need to create a router query engine. We will use the `RouterQueryEngine` to create a router query engine:
We're defining two query engines, one for summarization and one for retrieving specific context. The router query engine will select the most appropriate query engine based on the query.
```ts
const queryEngine = RouterQueryEngine.fromDefaults({
queryEngineTools: [
{
queryEngine: vectorQueryEngine,
description: "Useful for summarization questions related to Abramov",
},
{
queryEngine: summaryQueryEngine,
description: "Useful for retrieving specific context from Abramov",
},
],
serviceContext,
});
```
## Querying the Router Query Engine
Finally, we can query the router query engine:
```ts
const summaryResponse = await queryEngine.query({
query: "Give me a summary about his past experiences?",
});
console.log({
answer: summaryResponse.response,
metadata: summaryResponse?.metadata?.selectorResult,
});
```
## Full code
```ts
import {
OpenAI,
RouterQueryEngine,
SimpleDirectoryReader,
SimpleNodeParser,
SummaryIndex,
VectorStoreIndex,
serviceContextFromDefaults,
} from "llamaindex";
async function main() {
// Load documents from a directory
const documents = await new SimpleDirectoryReader().loadData({
directoryPath: "node_modules/llamaindex/examples",
});
// Parse the documents into nodes
const nodeParser = new SimpleNodeParser({
chunkSize: 1024,
});
// Create a service context
const serviceContext = serviceContextFromDefaults({
nodeParser,
llm: new OpenAI(),
});
// Create indices
const vectorIndex = await VectorStoreIndex.fromDocuments(documents, {
serviceContext,
});
const summaryIndex = await SummaryIndex.fromDocuments(documents, {
serviceContext,
});
// Create query engines
const vectorQueryEngine = vectorIndex.asQueryEngine();
const summaryQueryEngine = summaryIndex.asQueryEngine();
// Create a router query engine
const queryEngine = RouterQueryEngine.fromDefaults({
queryEngineTools: [
{
queryEngine: vectorQueryEngine,
description: "Useful for summarization questions related to Abramov",
},
{
queryEngine: summaryQueryEngine,
description: "Useful for retrieving specific context from Abramov",
},
],
serviceContext,
});
// Query the router query engine
const summaryResponse = await queryEngine.query({
query: "Give me a summary about his past experiences?",
});
console.log({
answer: summaryResponse.response,
metadata: summaryResponse?.metadata?.selectorResult,
});
const specificResponse = await queryEngine.query({
query: "Tell me about abramov first job?",
});
console.log({
answer: specificResponse.response,
metadata: specificResponse.metadata.selectorResult,
});
}
main().then(() => console.log("Done"));

# ResponseSynthesizer
The ResponseSynthesizer is responsible for sending the query, nodes, and prompt templates to the LLM to generate a response. There are a few key modes for generating a response:
- `Refine`: "create and refine" an answer by sequentially going through each retrieved text chunk.
This makes a separate LLM call per Node. Good for more detailed answers.
- `CompactAndRefine` (default): "compact" the prompt during each LLM call by stuffing as
many text chunks that can fit within the maximum prompt size. If there are
too many chunks to stuff in one prompt, "create and refine" an answer by going through
multiple compact prompts. The same as `refine`, but should result in less LLM calls.
- `TreeSummarize`: Given a set of text chunks and the query, recursively construct a tree
and return the root node as the response. Good for summarization purposes.
- `SimpleResponseBuilder`: Given a set of text chunks and the query, apply the query to each text
chunk while accumulating the responses into an array. Returns a concatenated string of all
responses. Good for when you need to run the same query separately against each text
chunk.
```typescript
import { NodeWithScore, ResponseSynthesizer, TextNode } from "llamaindex";
const responseSynthesizer = new ResponseSynthesizer();
const nodesWithScore: NodeWithScore[] = [
{
node: new TextNode({ text: "I am 10 years old." }),
score: 1,
},
{
node: new TextNode({ text: "John is 20 years old." }),
score: 0.5,
},
];
const response = await responseSynthesizer.synthesize({
query: "What age am I?",
nodesWithScore,
});
console.log(response.response);
```
The `synthesize` function also supports streaming, just add `stream: true` as an option:
```typescript
const stream = await responseSynthesizer.synthesize({
query: "What age am I?",
nodesWithScore,
stream: true,
});
for await (const chunk of stream) {
process.stdout.write(chunk.response);
}
```

# Retriever
A retriever in LlamaIndex is what is used to fetch `Node`s from an index using a query string. Aa `VectorIndexRetriever` will fetch the top-k most similar nodes. Meanwhile, a `SummaryIndexRetriever` will fetch all nodes no matter the query.
```typescript
const retriever = vector_index.asRetriever();
retriever.similarityTopK = 3;
// Fetch nodes!
const nodesWithScore = await retriever.retrieve("query string");

# Observability
LlamaIndex provides **one-click observability** 🔭 to allow you to build principled LLM applications in a production setting.
A key requirement for principled development of LLM applications over your data (RAG systems, agents) is being able to observe, debug, and evaluate
your system - both as a whole and for each component.
This feature allows you to seamlessly integrate the LlamaIndex library with powerful observability/evaluation tools offered by our partners.
Configure a variable once, and you'll be able to do things like the following:
- View LLM/prompt inputs/outputs
- Ensure that the outputs of any component (LLMs, embeddings) are performing as expected
- View call traces for both indexing and querying
Each provider has similarities and differences. Take a look below for the full set of guides for each one!
## OpenLLMetry
[OpenLLMetry](https://github.com/traceloop/openllmetry-js) is an open-source project based on OpenTelemetry for tracing and monitoring
LLM applications. It connects to [all major observability platforms](https://www.traceloop.com/docs/openllmetry/integrations/introduction) and installs in minutes.
### Usage Pattern

# المفاهيم على المستوى العالي
`تمت ترجمة هذه الوثيقة تلقائيًا وقد تحتوي على أخطاء. لا تتردد في فتح طلب سحب لاقتراح تغييرات.`
يساعدك LlamaIndex.TS في بناء تطبيقات قائمة على LLM (مثل Q&A و chatbot) على بيانات مخصصة.
في هذا الدليل عن المفاهيم على المستوى العالي، ستتعلم:
- كيف يمكن لـ LLM الإجابة على الأسئلة باستخدام بياناتك الخاصة.
- المفاهيم الرئيسية والوحدات في LlamaIndex.TS لبناء خط أنابيب الاستعلام الخاص بك.
## الإجابة على الأسئلة عبر بياناتك
يستخدم LlamaIndex طريقة مكونة من مرحلتين عند استخدام LLM مع بياناتك:
1. **مرحلة الفهرسة**: إعداد قاعدة المعرفة، و
2. **مرحلة الاستعلام**: استرداد السياق ذي الصلة من المعرفة لمساعدة LLM في الاستجابة لسؤال
![](./_static/concepts/rag.jpg)
تُعرف هذه العملية أيضًا باسم "استرجاع معزز للتوليد" (RAG).
يوفر LlamaIndex.TS أدوات أساسية لجعل كلا المرحلتين سهلتين للغاية.
دعنا نستكشف كل مرحلة بالتفصيل.
### مرحلة الفهرسة
يساعدك LlamaIndex.TS في إعداد قاعدة المعرفة باستخدام مجموعة من موصلات البيانات والفهارس.
![](./_static/concepts/indexing.jpg)
[**محمّلات البيانات**](./modules/high_level/data_loader.md):
موصل البيانات (أي `Reader`) يقوم بتجميع البيانات من مصادر بيانات مختلفة وتنسيقات بيانات مختلفة في تمثيل بسيط للـ `Document` (نص وبيانات تعريفية بسيطة).
[**المستندات / العقد**](./modules/high_level/documents_and_nodes.md): المستند هو حاوية عامة حول أي مصدر بيانات - على سبيل المثال، ملف PDF، نتائج واجهة برمجة التطبيقات، أو بيانات استرداد من قاعدة بيانات. العقد هو الوحدة الذرية للبيانات في LlamaIndex ويمثل "قطعة" من المستند الأصلي. إنه تمثيل غني يتضمن بيانات تعريفية وعلاقات (مع عقد أخرى) لتمكين عمليات الاسترجاع الدقيقة والتعبيرية.
[**فهارس البيانات**](./modules/high_level/data_index.md):
بمجرد أن تقوم بتجميع بياناتك، يساعدك LlamaIndex في فهرسة البيانات في تنسيق سهل الاسترداد.
تحت الغطاء، يقوم LlamaIndex بتحليل المستندات الخام إلى تمثيلات وسيطة، وحساب تضمينات الناقلات، وتخزين بياناتك في الذاكرة أو على القرص.

### مرحلة الاستعلام
في مرحلة الاستعلام، يقوم خط الأنابيب للاستعلام بجلب السياق الأكثر صلة بناءً على استعلام المستخدم،
ويمرر ذلك إلى LLM (جنبًا إلى جنب مع الاستعلام) لتوليد استجابة.
يمنح ذلك LLM معرفة محدثة ليست موجودة في بيانات التدريب الأصلية لديه،
(مما يقلل أيضًا من الهلوسة).
التحدي الرئيسي في مرحلة الاستعلام هو الاسترجاع والتنسيق والاستدلال عبر قواعد المعرفة (المحتملة).
يوفر LlamaIndex وحدات قابلة للتركيب تساعدك في بناء ودمج خطوط أنابيب RAG لـ Q&A (محرك الاستعلام)، chatbot (محرك الدردشة)، أو كجزء من وكيل.
يمكن تخصيص هذه الكتل البنائية لتعكس تفضيلات التصنيف، وكذلك تركيبها للاستدلال عبر عدة قواعد معرفة بطريقة منظمة.
![](./_static/concepts/querying.jpg)
#### الكتل الأساسية
[**مسترجعات**](./modules/low_level/retriever.md):
يحدد المسترجع كيفية استرجاع السياق ذي الصلة بكفاءة من قاعدة المعرفة (أي الفهرس) عند إعطاء استعلام.
تختلف منطق الاسترجاع المحددة حسب الفهارس المختلفة، والأكثر شيوعًا هو الاسترجاع الكثيف ضد فهرس الناقل.
[**مركبات الاستجابة**](./modules/low_level/response_synthesizer.md):
تقوم مركبة الاستجابة بتوليد استجابة من LLM باستخدام استعلام المستخدم ومجموعة معينة من أجزاء النص المسترجعة.
"
#### خطوط الأنابيب
[**محركات الاستعلام**](./modules/high_level/query_engine.md):
محرك الاستعلام هو خط أنابيب شامل يتيح لك طرح الأسئلة على بياناتك.
يأخذ استعلامًا بلغة طبيعية ويعيد استجابة، جنبًا إلى جنب مع السياق المرجعي المسترجع والممرر إلى LLM.
[**محركات الدردشة**](./modules/high_level/chat_engine.md):
محرك الدردشة هو خط أنابيب شامل لإجراء محادثة مع بياناتك
(عدة تفاعلات بدلاً من سؤال وجواب واحد).

# ما هو LlamaIndex.TS؟
`تمت ترجمة هذه الوثيقة تلقائيًا وقد تحتوي على أخطاء. لا تتردد في فتح طلب سحب لاقتراح تغييرات.`
LlamaIndex.TS هو إطار بيانات لتطبيقات LLM لاستيعاب وتنظيم والوصول إلى البيانات الخاصة أو الخاصة بالمجال. في حين أن حزمة Python متاحة أيضًا (انظر [هنا](https://docs.llamaindex.ai/en/stable/)), يوفر LlamaIndex.TS ميزات أساسية في حزمة بسيطة ، محسنة للاستخدام مع TypeScript.
## 🚀 لماذا LlamaIndex.TS؟
في جوهرها ، توفر LLMs واجهة لغة طبيعية بين البشر والبيانات المستنتجة. تأتي النماذج المتاحة على نطاق واسع محملة مسبقًا بكميات هائلة من البيانات المتاحة للجمهور ، من ويكيبيديا وقوائم البريد الإلكتروني إلى الكتب المدرسية وشفرة المصدر.
غالبًا ما تتطلب التطبيقات المبنية على LLMs تعزيز هذه النماذج بالبيانات الخاصة أو الخاصة بالمجال. للأسف ، يمكن توزيع هذه البيانات عبر تطبيقات ومخازن بيانات معزولة. إنها خلف واجهات برمجة التطبيقات ، في قواعد البيانات SQL ، أو محبوسة في ملفات PDF وعروض تقديمية.
هنا يأتي دور **LlamaIndex.TS**.
## 🦙 كيف يمكن أن يساعد LlamaIndex.TS؟
يوفر LlamaIndex.TS الأدوات التالية:
- **تحميل البيانات**: استيعاب البيانات الحالية الخاصة بك بتنسيقات `.txt`, `.pdf`, `.csv`, `.md` و `.docx` مباشرة.
- **فهارس البيانات**: تنظيم البيانات الخاصة بك في تمثيلات وسيطة سهلة وفعالة للاستخدام من قبل LLMs.
- **المحركات**: توفر واجهات الوصول إلى اللغة الطبيعية لبياناتك. على سبيل المثال:
- محركات الاستعلام هي واجهات استرجاع قوية للإخراج المعزز بالمعرفة.
- محركات الدردشة هي واجهات محادثة للتفاعلات "ذهابًا وإيابًا" متعددة الرسائل مع بياناتك.
## 👨‍👩‍👧‍👦 من أجل من هو LlamaIndex؟
يوفر LlamaIndex.TS مجموعة أدوات أساسية ، ضرورية لأي شخص يقوم ببناء تطبيقات LLM باستخدام JavaScript و TypeScript.
يتيح لنا واجهة برمجة التطبيقات على مستوى عالي استخدام LlamaIndex.TS لاستيعاب واستعلام البيانات الخاصة بهم.
بالنسبة للتطبيقات المعقدة أكثر ، تتيح لنا واجهات برمجة التطبيقات على مستوى أدنى للمستخدمين المتقدمين تخصيص وتوسيع أي وحدة - موصلات البيانات والفهارس وأجهزة الاسترجاع ومحركات الاستعلام - لتناسب احتياجاتهم.
## البدء
`npm install llamaindex`
تتضمن وثائقنا [تعليمات التثبيت](./installation.mdx) و[دليل البداية](./starter.md) لبناء تطبيقك الأول.
بمجرد أن تكون جاهزًا وتعمل ، يحتوي [مفاهيم عالية المستوى](./getting_started/concepts.md) على نظرة عامة على الهندسة المعمارية المتعددة المستويات لـ LlamaIndex. لمزيد من الأمثلة العملية التفصيلية ، يمكنك الاطلاع على [دروس النهاية إلى النهاية](./end_to_end.md).
