xopen v1.0.0

xopen - Open a file with the default application

xopen provides a dead-simple Promise API for opening files from Node on Windows, macOS, and Linux:

xopen(filepath)

filepath is a path to the file you wish to open. When you call xopen(), it returns a Promise that is resolved with the contents of stdout if the application successfully opens, and is rejected with an error if the application fails to open.

It's that easy.
