occt-import-js and the Open CASCADE Technology (OCCT) code compiled into it are licensed under the GNU Lesser General Public License version 2.1 (OCCT with the Open CASCADE exception version 1.0). They are redistributed unmodified: the WebAssembly module public/wasm/occt-import-js.wasm and its JavaScript glue, which is bundled into the viewer build and the library bundles. As LGPL-2.1 section 6 requires, the complete corresponding source code is available from: occt-import-js: https://github.com/kovacsv/occt-import-js (the version redistributed here is the one pinned in package-lock.json; tags match the npm version, e.g. v0.0.23) Open CASCADE Technology: https://github.com/Open-Cascade-SAS/OCCT and https://dev.opencascade.org (the OCCT revision occt-import-js builds against is recorded in that repository as a git submodule) The WebAssembly module is a separate file loaded at runtime, so it can be replaced with a rebuilt one (LGPL-2.1 section 6(b)).
