What events trigger mongoose pre hooks?

1

Hello, when we are creating mongoose pre hook we need to pass the event that will triger the function as the first argument. In this example, this is “save”:

someSchema.pre("save", function(next) {
    // do something
    next()
})

And I want to know more about this events. What is this “save” event and where I can find more about thems and their types?

Hello there.

Why not head over to the official documentation: https://mongoosejs.com/docs/api.html#document_Document-save

Poke around there, for a while. Hope this helps
