You know what to do... npm install and npm run dev or npm run build then npm run start - Yarn probably works too...

Literally just pointed Vercel to this repo to build and run automatically.

Cesium requires some files to be copied in a publicly accessible folder. This is achieved with CopyWebPackPlugin... BUT each copy statements requires info: { minimized: true }

It is just cleaner to have Cesium related components as client only components. So in this case, both the Cesium component and the dynamic ssr off wrappers are tagged with 'use client'

I won't go into every method that I've tried but every method I've tried has resulted in browser errors, Next.js errors, and/or Vercel (500 status filesystem) errors. Using the CopyWebPackPlugin, wrapping it in a dynamic component, and then finally importing the Cesium files via import inside a useEffect yielded 100% success.

With all the work above, it is very important to utilize the dynamically called Cesium and not import individual functions like you would normally. Also it is very important to type Cesium specific things with import type { xyz } from 'cesium' not import { xyz } from 'cesium'

Thank you https://github.com/willwill96 for helping me get started and please give this repo a star if it was helpful!
