Question

I need to programmatically access the current node version running in a library I am writing. Can’t seem to find this in the docs.

Answer 1

Look at process.version property.

Update 2023-09-05:

As noted below, the process.versions.node field provides the bare semver string (w/out the "v" prefix). Readers may find the following to be a convenient shorthand for accessing the different semver fields:

const [major, minor, patch] = process.versions.node.split('.').map(Number)
