vite-plugin-cesium-engine

Zero-config Vite plugin for @cesium/engine (v1.6.0) that automatically handles static asset copying, CSS injection, compile-time CESIUM_BASE_URL definition, and Ion token management. Designed specifically for the lightweight @cesium/engine package rather than the full cesium bundle. Key differentiators: no configuration needed for most cases, built-in .env support for per-environment Ion tokens, virtual module for runtime constants, and token validation. Release cadence: active with minor/patch updates every few months. Requires @cesium/engine >=11.0.0 and Vite >=5.0.0.
