Design a Next.js web application that serves as an interactive star map, representing the sky on the night when two individuals first met. The application should accept user inputs for date, time, and location to generate an accurate depiction of the night sky from that moment. It must include visual layers for stars, constellations, and celestial features, rendered with attention to aesthetic appeal and clarity. Incorporate interactive elements such as zooming, rotating, and clicking on stars or constellations to display educational information or details. Ensure the presentation is engaging, user-friendly, and responsive, capturing the wonder of that special night with a focus on a smooth user experience.
I see there's a fatal initialization error. Let me check the current state of the application files to identify the issue:
I see the issue. The star-canvas.tsx file is importing generateStarsForDateTime from @/lib/generateStars but that file doesn't exist. Let me check what files exist and then create the missing file:
Let me search more carefully for lib files:
Good! The lib/stars.ts file exists. The issue is that star-canvas.tsx is trying to import generateStarsForDateTime from a non-existent file. Let me fix this by removing the incorrect import and checking the star-canvas file more completely:
I found the issue. Line 8 imports generateStarsForDateTime from a non-existent file. This import is actually not used in the code since the StarField function uses getStarCatalog instead. Let me fix this:
Now let me check if all other necessary imports and functions in lib/stars.ts are properly exported:
Good! The stars.ts file has all the needed exports. Now let me check the other component files to ensure they're complete:
The components look good. Now let me check if there are any issues with the layout or other files:
Good! All the files are present. The issue was just the unused import. The application should now build and deploy successfully. The fix I applied removed the erroneous import of generateStarsForDateTime from the non-existent file lib/generateStars.ts, as this function wasn't being used in the code—the StarField component uses getStarCatalog from the existing lib/stars.ts file instead.
Your interactive star map application is now ready. It includes:
The deployment should now succeed with the dependency fix and import correction in place.
An error occurred during deployment. Please fix:

npm error code EINVALIDTAGNAME
npm error Invalid tag name "^r170" of package "three@^r170": Tags may not have any characters that encodeURIComponent encodes.
npm error A complete log of this run can be found in: /vercel/.npm/_logs/2026-02-11T16_54_03_035Z-debug-0.log
Error: Command "npm install" exited with 1
The issue is with the invalid Three.js version ^r170. This isn't a valid npm version tag. Let me fix it to a proper semantic version:
I can see the issue. The Three.js version is set to "three": "^r170" which is invalid. It should be "three": "^0.170.0". Let me fix this:
Fixed! The Three.js version was incorrectly specified as ^r170. I've updated it to the proper semantic version ^0.170.0, which is a valid npm package version. Your deployment should now succeed.
Develop a Next.js web application that provides an interactive star map, capturing the sky as it appeared on a specific night when two individuals first met. The application should allow users to input the date, time, and geographical location to generate an accurate, real-time visualization of the night sky from that moment. The visualization must include multiple layered elements such as stars, constellations, and celestial features, designed with a balance of visual appeal and informational clarity. Integrate interactive functionalities like zooming, rotating, and clickable stars or constellations that reveal educational data or details about the celestial objects. Prioritize an engaging, intuitive, and responsive user experience that transforms the viewing of that meaningful night into an immersive explorative journey.
