Error Message

Error: No "exports" main defined in node_modules/@fly/sprites/package.json
    at exportsNotFound (node:internal/modules/esm/resolve:…)

Cause

The package was ESM-only:

"type": "module",
"exports": {
  ".": {
    "import": "./dist/index.js"
  }
}

No "require" export was provided.
CommonJS runtimes (e.g., Nx/NestJS CJS builds) could not resolve the package.

Steps to Reproduce

1. Use a CJS backend build (e.g., Nx with "format": ["cjs"])
2. Install @fly/sprites
3. Import: import { SpritesClient } from "@fly/sprites";
4. Build or run backend → Resolution error thrown.

Proposed Solution

Add dual module support:

• Keep ESM build
• Add CJS build (dist/index.cjs)
• Add "require" condition in exports
• Keep ESM as default
• No runtime dependencies added
