How do I pipe output from node stdout to open command in Mac terminal?

I have a node project where I output a filename to stdout in the terminal with process.stdout.write(filename + '\n');. How can I pipe this output to the open command or some other command to open the file (an image in this case) with the default image viewer?

As Mark Setchell points out in the comments, you will need to pass -a <appname> to open the file with a specific application.
However, you will need to pipe the file to stdout instead of just the filename, fore example like this: 

var fs = require('fs');

fs.createReadStream("./test.jpg").pipe(process.stdout);

and then of yourse node yourNodeFile.js | open -f -a Preview.app
