ifczero

A complete IFC authoring, geometry and serialization library for the web, powered by IfcOpenShell.

Initialize

• init(overrides?: ModuleInitOverrides): Promise<EmscriptenModule> Loads the full bundled ifcopenshell.js and caches the module.
• initParse(overrides?: ModuleInitOverrides): Promise<EmscriptenModule> Loads bundled ifcparse.js and caches the module.

Runtime helpers:

• getModule(): EmscriptenModule
• hasModule(): boolean
• clearModule(): void
• moduleInstance: EmscriptenModule | null

Example using bundled full module:

import { init } from "ifczero";

await init({
  locateFile: (file) => new URL(`../wasm/${file}`, import.meta.url).pathname,
});

You can also import ifczero/wasm/*.js directly and use ccall/cwrap manually, but the TS APIs are the recommended layer.

Module Guides

• Parse.md
• Geom.md
• Serializers.md
• Util.md

Low-level Helpers

• loadModule(createModule, overrides?): Promise<EmscriptenModule>
• readString(ptr): string | null
• readF64Array(ptr, count): Float64Array
• readI32Array(ptr, count): Int32Array
• writeBytes(data): number

Raw Bindings

• Root: parseRaw, psetqtoRaw, ifcutilRaw, geomRaw, serializersRaw
• Namespaced: parse.raw, parse.rawPsetQto, parse.rawUtil, geom.raw, serializers.raw, util.raw

These are low-level direct C ABI wrappers.
