Seems its an error in ollama-js side as written in Vite documentation: https://vite.dev/guide/troubleshooting.html#module-externalized-for-browser-compatibility

Hey 👋

Vite is likely building a static site that may not be ran with node, so you don't have access to libraries that you require node for when trying to run with the built files.

Instead of importing from ollama, import from ollama/browser and it should work.

See the readme here: https://github.com/ollama/ollama-js?tab=readme-ov-file#browser-usage

[ejgutierrez74]

whats the difference between ollama and ollama/browser...would this be compatible with Vercel deployment?

[hexnaught]

would this be compatible with Vercel deployment

Yes.

As for differences, the code is in this repo, you can see for yourself! 😅 tldr; the non browser import uses nodejs dependencies and is usable via running an app with nodejs. The browser import uses dependences and code compatible with a browser environment. Your Vite setup is likely packaging up a static build, so it can be ran with nginx, caddy, go, rust... whatever you want to serve HTML. So if you import modules that are from node, they won't work.
