# YouTube transcripts

This covers how to load YouTube transcripts into LangChain documents.

## Setup

You'll need to install the [youtubei.js](https://www.npmjs.com/package/youtubei.js) to extract metadata:

```bash npm theme={null}
npm install @langchain/community @langchain/core youtubei.js
```

## Usage

You need to specify a link to the video in the `url`. You can also specify `language` in [ISO 639-1](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) and `addVideoInfo` flag.

```typescript theme={null}
import { YoutubeLoader } from "@langchain/community/document_loaders/web/youtube";

const loader = YoutubeLoader.createFromUrl("https://youtu.be/bZQun8Y4L2A", {
  language: "en",
  addVideoInfo: true,
});

const docs = await loader.load();

console.log(docs);
```
