📈 Serverless Trending API

A minimal scraping serverless API that returns trending videos based on a query, sorted by view count in descending order.

This is a Next.js API, it uses zero external dependencies outside of Next itself. The entire API is contained within api/search/route.ts, making it easy to plug into existing projects.

Features

• An /api/search endpoint that scrapes YouTube search results
• Returns JSON with title, link, channel, thumbnail, and views
• In-memory cache speeds up repeated requests
• Configurable settings for cache TTL and min/max result limit

Usage

1. A GET request is made to /api/search with a search term.
2. The server checks the in-memory cache; if a result exists, it returns cached data.
3. If no cache, it scrapes the YouTube search results page, extracts embedded JSON (ytInitialData), parses video info, and sorts by view count.
4. The result is cached and sent back as a JSON response.

/api/search

Query parameters:

• q: Search term
• limit (optional): Number of results (defaults to 1, maximum defaults to 4, all configurable)

Example local request using curl:

curl "http://localhost:3000/api/search?q=lofi&limit=4"

Example response:

{
  "videos": [
    {
      "title": "Lofi Chill Beats",
      "link": "https://www.youtube.com/watch?v=abc123",
      "channel": "Lofi Girl",
      "thumbnail": "https://i.ytimg.com/vi/abc123/hqdefault.jpg",
      "views": 1250000
    },
    ...
  ]
}

Returned fields:

• title: Video title text
• link: Full YouTube video URL
