JS Code in the native node module

[sudhakar3697]

Is it possible to access the following variants of node modules inside the N-API addon code(C/C++).

1. Built-in Node module (like fs, http).
2. Node module written in Javascript.
3. Native node module written using (NAN or oth).
4. Native node module written using N-API.

Thank you.

If I got it right, the key might be a module API in N-API to allow N-API modules to directly access other type of modules. Currently you have to pass require function or module instance to N-API modules on a setup phase from JS. With require there is no differences between these 4 types of modules AFAIK.

A module API is being proposed on nodejs/node#28464.

@sudhakar3697 you can call JavaScript functions, but is up to you to get those to the N-API module. For example if you pass the result of fs = require('fs') to an N-API function it can use N-API methods to get fields/functions on that an then call them.

Having said that it might be easier to keep some of that functionality in JS and call a higher level function from the N-API C function as opposed to making many of those calls in the N-API functcion. I also believe it would likely be better optimized with more of the calls together at the JS level as each back and forth adds overhead.

Thank you all :)
