How to add an internal module

[Melab]

To add a built-in module to the code, what code must be modified?

They're asking how to create a native module like fs and path, not how to create an npm package.

Not what I mean. Please reread my question.

Clone nodejs/node, add a .js file in lib/ folder, and run make -j12 (depends on your OS/platform, see https://github.com/nodejs/node/blob/HEAD/BUILDING.md for further instructions): voilà. You would now have a node executable at out/Release/node with the new built-in module you added.

If you're asking how that module could land on Node.js land, you would need to open a PR on this repo, adding docs, tests, and explanation why you think this module should be part of core. See https://github.com/nodejs/node/blob/HEAD/doc/guides/modules-in-core.md for more info.
