Configure the promise implementation

I wish to provide my own Promise implementation (core-js), so I do not want browserify do bundle the es6-promise module. Is there a simple way to configure axios not to require this module?

// Polyfill ES6 Promise if needed
require('es6-promise').polyfill();

+1 for allowing me to change the promise implementation.

@CrisLi I solved the issue by checking if Promise attribute is in the global scope, otherwise, window.Promise =BluebirdPromise;
