iTwin.js backends are built and tested on the following:
- Arch Linux
- Debian 11 "Bullseye"
- Windows 10 version 1803 (or greater)
- MacOS 10.15 (or greater)
They should run on most Windows, Linux and MacOS versions with Tier 1 support from Node.js. However, regular testing only occurs on the platforms listed above.
The following Node.js versions are officially supported by the iTwin.js backend code.
The minimum requirements are driven by Node's compatibility with a specific N-API version. iTwin.js currently requires N-API version 8. See the Node compatibility matrix for more details.
