Cesium Utils
A comprehensive utility library for CesiumJS that simplifies working with 3D geo-spatial visualizations
What is Cesium Utils?
@juun-roh/cesium-utils is a utility library that extends CesiumJS with abstractions and helper functions. It simplifies common tasks when building 3D geo-spatial applications, addressing pain points that I've encountered when working with Cesium.
This library is designed to complement CesiumJS, not to replace it. It works alongside the existing Cesium code and provides solutions to common challenges while maintaining the familiar Cesium paradigms. The project follows modern TypeScript practices and has comprehensive type definitions.
Why I Built This
Working extensively with CesiumJS, I found myself writing similar utility functions across multiple codebases. While CesiumJS is incredibly powerful, many common workflows require repetitive boilerplate code.
I created this library to encapsulate best practices, simplify complex operations, and provide a more developer-friendly experience when working with CesiumJS. The goal was to reduce cognitive load and accelerate development without sacrificing the flexibility and power of the underlying engine.
Key Features
The library provides specialized utilities to solve common challenges in CesiumJS development:
- Tag-based organization for entities, primitives, and data sources
- Bulk operations on collections (show/hide, style, remove)
- Simplified querying by properties, spatial extent, or custom functions
- Priority-based terrain compositing from multiple sources
- Geographical bounds for terrain source selection
- Smooth transitions between terrain sources
- Camera synchronization across multiple viewers
- Copying existing viewer by inheriting it's properties
- Consistent highlighting across entity types
- Customizable highlight styles with transitions

Installation
Prerequisites
The library requires CesiumJS as a peer dependency. Make sure you have it properly installed in your project:
You'll also need to ensure that CesiumJS assets are properly loaded in your application. Follow the official CesiumJS setup guide if you haven't already set up CesiumJS.
