Unless you need inprocess communication (you don't for NodeJS native API) you can just refer from one container to another.

If records are never deleted and you're okay with a few misses, use ExtentSizeFast, if you need the fastest precise runtime implementation use ExtentSize, in you need better compile speed and don't care about runtime speed use GetExtentSize.
