YouTube Data API in JavaScript: List Channel Videos
Most 'list YouTube channel videos' tutorials use jQuery + the search.list endpoint — that costs 100 quota units per call (vs 1 for the uploads-playlist trick) and exposes your API key in the browser. This guide does it right: modern fetch + async/await, the playlistItems.list pattern, server-side API key proxying with Cloudflare Workers or Next.js Route Handlers, channel handle → ID resolution, pagination with nextPageToken, and the oEmbed fallback for simple embeds without any API key at all.
