Returns an object containing commonly used constants for VM operations.
namespace
vm.constants
namespace constants
This constant, when used as the
contextObject
argument in vm APIs, instructs Node.js to create a context without wrapping its global object with another object in a Node.js-specific manner. As a result, theglobalThis
value inside the new context would behave more closely to an ordinary one.When
vm.constants.DONT_CONTEXTIFY
is used as thecontextObject
argument to createContext, the returned object is a proxy-like object to the global object in the newly created context with fewer Node.js-specific quirks. It is reference equal to theglobalThis
value in the new context, can be modified from outside the context, and can be used to access built-ins in the new context directly.A constant that can be used as the
importModuleDynamically
option tovm.Script
andvm.compileFunction()
so that Node.js uses the default ESM loader from the main context to load the requested module.For detailed information, see Support of dynamic
import()
in compilation APIs.
