How to execute a file with the default program from nodejs?

Question

Node.js

I use NodeJS in conjunction with NW.JS.
What are the ways? modules? it is possible exactly NodeJS means, without NW, JS?
For example: run an exe file, open a folder, open a picture in the default program

Answer 1

There is a ready-made package: https://www.npmjs.com/package/open
There are actually three lines of code inside, EMNIP :)
