Node 18 Upgrade for Server-side extensions
With 23C release, the version of Node.js used by server-side extensions (SSEs) is being upgraded to the latest long-term support version of Node.js 18 LTS.
In Internal testing, we have not found any incompatibilities. But, there are steps you should take to prepare ahead of time. The main risk for incompatibility is outdated npm libraries that may be used by your SSEs. Before your sites are upgraded to 23C(or beyond), you will need to verify that you’re using the latest version of each npm library and identify any changes that need to be made to your SSEs.
