Are there good tools to do physics engine type validations on a node server?

I am building a platform that will have some sort of room setup where objects are defined by starting coordinates (xyz) and properties (width/height/length). This entire room will be built in a singular json file. I would then like to validate this setup based on physics engine type qualities. Are two objects touching? (and how) Are two objects overlapping etc. I would like to do this server side using a node app.

I can build something like this myself but I feel like there might already be some great tools out there to use. Any suggestions would be help full.
