landsat-text-api

Render any text using NASA's landsat satellite images!

Quick start

Make sure you have bun installed.

bun install
bun run dev

Endpoints

• GET /api/health — checks if the service is up
• GET /api/capture?text=NASA — returns JSON metadata
• GET /api/capture.png?text=NASA — returns PNG
• POST /api/capture — same as GET but with JSON body {"text": "nasa"}

Example

curl "http://localhost:3000/api/capture.png?text=nasa" -o landsat-nasa.png

Working

• Look up each letter in the dataset and builds a local JSON.
• Fetch the letter images from NASA's CDN and downloads them as cache on first startup.
• Renders them using TypeScript.

Each letter can have a few variants provided by NASA so the same input picks the same set of variants

Commands

• bun run dev — start server with watch
• bun run start — run server

And that's all!
