web-ifc Engine: Direct WASM IFC Parser

Overview

web-ifc is the WASM-powered IFC parsing engine beneath the ThatOpen component stack. It reads and writes IFC files at native speed in browser and Node.js environments. The central class is IfcAPI.

• Package: web-ifc (npm)
• Source: https://github.com/ThatOpen/engine_web-ifc
• Environments: Browser, Node.js (single-threaded and multi-threaded WASM)
• License: MPL-2.0

When using ThatOpen components (@thatopen/components), you rarely call web-ifc directly — the IfcLoader component wraps it. Use this skill when you need low-level IFC access, custom geometry extraction, or bulk property queries outside the component framework.
