Install

The IFC stack is published for four languages. They all share one Rust core (ADR 0013), so a file read in one reads the same in the others.

Language	Package	Latest release	Install	Requires	Reference
Rust	openbim-ifc	0.9.0 (2026-09-29)	cargo add openbim-ifc	Rust 1.88.0	openbim-ifc
JavaScript / TypeScript	@openbim/ifc	0.2.0 (2026-09-29)	npm install @openbim/ifc	Node >=18	openbim-ifc-wasm
Python	openbim-ifc	0.2.0 (2026-09-29)	pip install openbim-ifc	Python >=3.9	openbim-ifc-py
C / C++	openbim-ifc-capi (not published)	not released	build from source	a C11 or C++17 compiler, and Rust to build	openbim-ifc-capi

The table is generated from each package's changelog and manifest, so the versions and toolchain floors on this page are the ones the packages declare. The install commands take no version and resolve to the newest release.

Rust

Depend on the openbim-ifc facade and turn on only the features you need. With no features beyond the default you get the model and the STEP codec, and nothing else is compiled:

cargo add openbim-ifc                                  # model + STEP
cargo add openbim-ifc --features properties,spatial    # plus two domains

The library is imported as ifc (use ifc::{Codec, StepCodec};). Every feature, and the crate each one enables, is listed on the facade's reference page; the crate reference describes each crate.

JavaScript and TypeScript

npm install @openbim/ifc

See JavaScript and TypeScript.

Python

pip install openbim-ifc

See Python.

C and C++

The C ABI is not packaged yet. Build it from a checkout and link the static or shared library against crates/openbim-ifc-capi/include/openbim_ifc.h:

cargo build -p openbim-ifc-capi --release

See C and C++.
