Detect if bluebird is used instead of native Promises

Is there a way to automatically verify that my code uses bluebird promises instead of native ones? In other words I would like every file that uses Promise object to be checked if there is a var Promsie = require('bluebird'); in the beginning of the file.

If there is no such tool I will happily write one, when I have time that is:).

Edit I’m using Node v4 with ES6 and the way I’m using promises is polyfilling/replacing original Promise object with Bluebird one. It’s the same approach that Bluebird promotes in their documentation here.

I think most people just use bluebird to replace the global Promise object and call it a day.

@benjamingr so please modify Bluebird documentation. Currently Bluebird is encouraging usage of var Promise = require('bluebird'); which is a trap. By trap I mean situation whenever somebody forgets to import blurbird and by mistake original Promise object is used and application either breaks (easy to fix) or there are silent errors (impossible to fix, because you don’t even know that there is an error somewhere). As you may know original Promises don’t print errors that are thrown from within promise chain.

One of the reasons I use bluebird is that it prints uncaught errors to the console.
