# Supadata

This page covers how to use the [Supadata](https://supadata.ai) ecosystem within LangChain. It allows you to load data from YouTube, TikTok, and other platforms.

## Installation and setup

To use Supadata, you need to install the standalone integration package.

```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
npm install @supadata/langchain-js
```

## Document Loader

The Supadata integration allows you to load content from various video platforms as LangChain documents. It supports fetching transcripts and metadata.

### Usage

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import { SupadataLoader } from "@supadata/langchain-js";

const loader = new SupadataLoader({
  apiKey: "YOUR_SUPADATA_API_KEY", // or process.env.SUPADATA_API_KEY
});

const docs = await loader.load({
  url: "https://www.youtube.com/watch?v=dQw4w9WgXcQ",
  operation: "transcript",
  lang: "en",
  text: true,
  mode: "auto",
});

console.log(docs[0].pageContent);
console.log(docs[0].metadata);
```

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import { SupadataLoader } from "@supadata/langchain-js";

const loader = new SupadataLoader({
