Mongoose global error event

Feature query

I was wondering is there's some way to get all errors in mongoose like some sort of global error event on mongoose or even at a collection level ?

node version: 8.11.3
mongoose version: 4.13.6

This is a great idea. We should add the ability to handle errors at the model level and the connection level. Right now the closest thing we have is a Model.on('error') event, but that only catches errors from index builds and uncaught errors in callbacks.

do we have a global way of getting all errors?

mongoose.on('') ?

@sibelius not for all errors. You'd need to register an error handler on every model, for (const model of Object.values(mongoose.models)) { model.on('error', ...) }
