Yi Ding 0904d3dc5d allow adding of nodes with hash comparisons
Allows our scripts to be run repeatedly with vector store backing and
persistence without throwing an error.

This is rudimentary support which doesn't work if the document has
changed over time.

Also added the insert and delete functions so that documents can be
added manually.

Yi Ding 7699f5432d set typedoc revision to main
In theory this will stop the API docs thrashing on every build.

Of course, there is a drawback in that if main changes but we haven't
released a new version of the docs yet the links will go out of date.

So longer term we might want to investigate some kind of variable where
we can continue to have up to date revs but keep the rev in a single
variable somewhere:

https://github.com/facebook/docusaurus/issues/395

In the meantime much smaller commits will be a relief

There is an existing ["simple"](/apps/simple/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.

Check out our NextJS playground at https://llama-playground.vercel.app/. The source is available at https://github.com/run-llama/ts-playground
## 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.
- [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.
- [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.

- [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.

---
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 OPEN_AI_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.

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/high_level/documents_and_nodes.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.
