Execute functions by importing from scripts/src/index.ts:
import { analyzeChannel, searchAndAnalyze } from './scripts/src/index.js';
const analysis = await analyzeChannel('UCxxxxxxxx');
Or run directly with tsx:
npx tsx scripts/src/index.ts
Every analysis follows three phases:
Run API functions. Each call hits the YouTube Data API and returns structured data.
All results automatically save as JSON files to results/{category}/. File naming patterns:
{sanitized_name}.jsonYYYYMMDD_HHMMSS__{operation}.jsonAfter analysis, read the saved JSON files and create a markdown summary in results/summaries/ with data tables, comparisons, and insights.
| Function | Purpose | What it gathers |
|---|---|---|
| ---------- | --------- | ---------------- |
analyzeChannel(channelId) | Full channel analysis | Channel info, recent videos, avg views per video |
compareChannels(channelIds) | Compare multiple channels | Side-by-side subscribers, views, video counts |
analyzeVideo(videoId) | Video performance analysis | Views, likes, comments, like rate, comment rate |
searchAndAnalyze(query, maxResults?) | Search + stats | Search results with full video statistics |
For granular control, import specific functions from the API modules. See references/api-reference.md for the complete list of 13 API functions with parameters, types, and examples.
| Function | Purpose |
|---|---|
| ---------- | --------- |
getChannel(channelId) | Get full channel details |

├── search/ # Search results
└── summaries/ # Human-readable markdown summaries
import { listResults, loadResult, getLatestResult } from './scripts/src/index.js';
// List recent results
const files = listResults('channels', 10);
// Load a specific result
const data = loadResult(files[0]);
// Get most recent result for an operation
const latest = getLatestResult('channels', 'channel_analysis');
