Dynamic module import #1050
Description
It shouldn't be required to install node module per instance. Rarely required modules like SAML should be imported on demand.
There are a couple of experimental flags which can make this happen. These are subject to change hence we will have to wait for a future node release where these features become stable.
--experimental-network-imports
Importing network based modules using https: and http: is supported under the --experimental-network-imports flag. This allows web browser-like imports to work in Node.js with a few differences due to application stability and security concerns that are different when running in a privileged environment instead of a browser sandbox.
The vm.Module class provides a low-level interface for using ECMAScript modules in VM contexts. It is the counterpart of the vm.Script class that closely mirrors Module Records as defined in the ECMAScript specification.
Unlike vm.Script however, every vm.Module object is bound to a context from its creation. Operations on vm.Module objects are intrinsically asynchronous, in contrast with the synchronous nature of vm.Script objects. The use of 'async' functions can help with manipulating vm.Module objects.
