whiches is essentially a streaming wrapper around isaacs’s which that adds support for arrays of executables.

npm install whiches
var whiches = require('whiches')
 
whiches('vlc')
  .pipe(process.stdout)
 
// => /usr/bin/vlc 
 
whiches(['chromium', 'node'])
  .pipe(process.stdout)
 
// => /usr/bin/chromium 
//    /usr/bin/node  
 
whiches(['fakeprogram', 'node', 'anotherfakeprogram'])
  .pipe(process.stdout)
 
// => /usr/bin/node 

Each path that whiches outputs ends with a new line character, so stream consumers will want to be aware of that.
