Make including packages possible

[CodingBobby]

When trying to require an npm package or any other local .js file, an error appears saying it was not found.

internal/modules/cjs/loader.js:583
    throw err;
    ^
Error: Cannot find module 'module-name-or-path'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:581:15)

It would be a very useful feature to have.
