ThatOpen Component Syntax

Purpose

This skill covers the syntax and usage patterns for ThatOpen's component system. It provides exact method signatures, lifecycle interface contracts, event system API, and reactive collection patterns. For architectural overview and design rationale, see thatopen-core-architecture.

Version: @thatopen/components 3.3.x

The components.get() Pattern

ALWAYS obtain component instances through the singleton registry:

import * as OBC from "@thatopen/components";

const components = new OBC.Components();
