# YouTube Analytics Toolkit

## Setup

Install dependencies:

```bash
cd scripts && npm install
```

Configure credentials by creating a `.env` file in the project root:

```
YOUTUBE_API_KEY=AIzaSy...your-api-key
YOUTUBE_DEFAULT_MAX_RESULTS=50
```

**Prerequisites**: A Google Cloud project with the YouTube Data API v3 enabled. Get your API key from the [Google Cloud Console](https://console.cloud.google.com/apis/credentials).

## Quick Start

| User says | Function to call |
|-----------|-----------------|
| "Analyze this YouTube channel" | `analyzeChannel(channelId)` |
| "Compare these two channels" | `compareChannels([id1, id2])` |
| "How is this video performing?" | `analyzeVideo(videoId)` |
| "Search YouTube for [topic]" | `searchAndAnalyze(query)` |
| "Get stats for this channel" | `getChannelStats(channelId)` |
| "Get this video's view count" | `getVideoStats(videoId)` |
| "Find channels about [topic]" | `searchChannels(query)` |
| "Show recent uploads from this channel" | `getChannelVideos(channelId)` |

Execute functions by importing from `scripts/src/index.ts`:

```typescript
import { analyzeChannel, searchAndAnalyze } from './scripts/src/index.js';

const analysis = await analyzeChannel('UCxxxxxxxx');
```

Or run directly with tsx:

```bash
npx tsx scripts/src/index.ts
```

## Workflow Pattern

Every analysis follows three phases:

### 1. Analyze
Run API functions. Each call hits the YouTube Data API and returns structured data.

### 2. Auto-Save
All results automatically save as JSON files to `results/{category}/`. File naming patterns:
- Named results: `{sanitized_name}.json`
- Auto-generated: `YYYYMMDD_HHMMSS__{operation}.json`

### 3. Summarize
After analysis, read the saved JSON files and create a markdown summary in `results/summaries/` with data tables, comparisons, and insights.
