Problem with babel

[iraniamir]

if we use babel we got this error : (i convert this class to es5 and works, i think you missed something)

/home/amir/Desktop/NodeJs/cannal/node_modules/mongodb/lib/utils.js:123
    process.nextTick(function() { throw err; });
                                  ^

You may want to make an exception and not run your models through a transpiler like babel.

Though I am curious how are you using the constructor without the new keyword. Can you share example code that produces this error?

[iraniamir]

i exactly use aqua source, this is my code https://github.com/jedireza/aqua/blob/master/server/models/session.js

That's the model. However it sounds like how that model get's instantiated is the problem (not using a new keyword.

Sharing a reproducible code snippet that I can run to get the same error would be most helpful.

This isn't a reproducible code example, just the code that you linked to. At this point I'm unable to help since I don't have enough information to work with. I'd also venture to say that you shouldn't need to transpile your model code since it's not intended for the browser.
