How to Generate AI Images, Videos, Music & Speech Programmatically with JavaScript

AI-generated media is everywhere — product images, marketing videos, background music, voiceovers. But if you've tried integrating it into a JavaScript project, you know the pain: each provider has its own SDK, its own auth flow, its own async patterns. You end up writing more glue code than actual product logic. In this post, I'll walk through how to programmatically generate images, videos, music, and speech in JavaScript/TypeScript — with real code you can copy into your project today. The Problem with Multiple AI Media APIs Let's say you want your app to generate a product image, a short promo video, and a background track. You'd need: An OpenAI or Google account for image generation A Kling or Veo account for video generation A Suno account for music generation Three different SDKs, three billing dashboards, three sets of API keys Custom polling logic for each (none of them return results synchronously) That's a lot of overhead before you've written a single line of business logic
