Xpell Core

Xpell Core is the foundational runtime of the Xpell framework.
It provides the core engine, real-time update loop, event system, data layer, and utilities used by XUI (UI engine), X3D (3D engine), and higher-level Xpell modules.

Xpell Core is designed for high-performance, real-time JavaScript/TypeScript applications, including:

• real-time UI
• AI-driven interfaces
• dashboards
• data-driven visualizations
• WebGL/3D experiences
• vibe-coded apps (LLM-assisted development)

If you are building with Xpell, this package provides the low-level primitives the rest of the framework depends on.

Features

• Real-time engine update loop
• Event and signal system
• Core data structures
• Object lifecycle management
• Shared utilities for UI, 3D, and AI modules
• Zero-dependency, lightweight foundation
• Written in TypeScript

Installation

npm install xpell-core
pnpm add xpell-core
yarn add xpell-core
