## Structure
This is a monorepo built with Turborepo
Right now there are two packages of importance:
packages/core which is the main NPM library llamaindex
apps/simple is where the demo code lives
### Turborepo docs
You can checkout how Turborepo works using the built in [README-turborepo.md](README-turborepo.md)
## Getting Started
Install NodeJS. Preferably v18 using nvm or n.
Inside the LlamaIndexTS directory:
```
npm i -g pnpm ts-node
pnpm install
```
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.
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
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
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 simple]
```
To install packages for every package or application run
```
pnpm add -w [NPM Package]
```
### Docs
To contribute to the docs, go to the docs website folder and run the Docusaurus instance.
```bash
cd apps/docs
pnpm install
pnpm start
```
That should start a webserver which will serve the docs on https://localhost:3000
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.

# 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
# llamaindex-ts-doc
LlamaIndex is a data framework for your LLM application.
This is a Next.js application generated with
[Create Fumadocs](https://github.com/fuma-nama/fumadocs).
Use your own data with large language models (LLMs, OpenAI ChatGPT and others) in Typescript and Javascript.
Documentation: https://ts.llamaindex.ai/
## What is LlamaIndex.TS?
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.
## Getting started with an example:
LlamaIndex.TS requries Node v18 or higher. You can download it from https://nodejs.org or use https://nvm.sh (our preferred option).
In a new folder:
Run development server:
```bash
export OPENAI_API_KEY="sk-......" # Replace with your key from https://platform.openai.com/account/api-keys
pnpm init
pnpm install typescript
pnpm exec tsc -init # if needed
pnpm install llamaindex
pnpm install @types/node
npm run dev
# or
pnpm dev
# or
yarn dev
```
Create the file example.ts
Open http://localhost:3000 with your browser to see the result.
```ts
// example.ts
import fs from "fs/promises";
import { Document, VectorStoreIndex } from "llamaindex";
## Learn More
async function main() {
// Load essay from abramov.txt in Node
const essay = await fs.readFile(
"node_modules/llamaindex/examples/abramov.txt",
"utf-8"
);
To learn more about Next.js and Fumadocs, take a look at the following
resources:
// 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(
"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
```
## Core concepts for getting started:
- [Document](packages/core/src/Node.ts): A document represents a text file, PDF file or other contiguous piece of data.
- [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/core/src/Embedding.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 quesiton.
- [Indices](packages/core/src/indices/): Indices store the Nodes and the embeddings of those nodes. QueryEngines retrieve Nodes from these Indices using embedding similarity.
- [QueryEngine](packages/core/src/QueryEngine.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.
- [ChatEngine](packages/core/src/ChatEngine.ts): A ChatEngine helps you build a chatbot that will interact with your Indices.
- [SimplePrompt](packages/core/src/Prompt.ts): 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.

# Website
This website is built using [Docusaurus 2](https://docusaurus.io/), a modern static website generator.
### Installation
```
$ pnpm
```
### Local Development
```
$ pnpm start
```
This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.
However, the searchbar may not function with `yarn start`. Instead, run `yarn build` and launch a server:
```
$ npx http-server ./build
```
### Build
```
$ pnpm build
```
This command generates static content into the `build` directory and can be served using any static contents hosting service.
### Deployment
Using SSH:
```
$ USE_SSH=true pnpm deploy
```
Not using SSH:
```
$ GIT_USER=<Your GitHub username> pnpm deploy
```
If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the `gh-pages` branch.

CondenseQuestionChatEngine is used in conjunction with a Index (for example VectorStoreIndex).
It does two steps on taking a user's chat message: first, it condenses the chat message
with the previous chat history into a question with more context.
Then, it queries the underlying Index using the new question with context and returns
the response.
CondenseQuestionChatEngine performs well when the input is primarily questions about the
underlying data. It performs less well when the chat messages are not questions about the
data, or are very referential to previous context.

ContextChatEngine uses the Index to get the appropriate context for each query.
The context is stored in the system prompt, and the chat history is preserved,
ideally allowing the appropriate context to be surfaced for each query.

# LlamaIndex.TS
Use your own data with large language models (LLMs, OpenAI ChatGPT and others) in Typescript and Javascript.
## What is LlamaIndex.TS?
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.
## Getting started with an example:
LlamaIndex.TS requries Node v18 or higher. You can download it from https://nodejs.org or use https://nvm.sh (our preferred option).
In a new folder:
```bash
export OPENAI_API_KEY="sk-......" # Replace with your key from https://platform.openai.com/account/api-keys
npx tsc -init # if needed
pnpm install llamaindex
```
Create the file example.ts
```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(
"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
```
## Core concepts for getting started:
- [Document](packages/core/src/Node.ts): A document represents a text file, PDF file or other contiguous piece of data.
- [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/core/src/Embedding.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 quesiton.
- [Indices](packages/core/src/indices/): Indices store the Nodes and the embeddings of those nodes. QueryEngines retrieve Nodes from these Indices using embedding similarity.
- [QueryEngine](packages/core/src/QueryEngine.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.
- [ChatEngine](packages/core/src/ChatEngine.ts): A ChatEngine helps you build a chatbot that will interact with your Indices.
- [SimplePrompt](packages/core/src/Prompt.ts): 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.
