Built-in error types
Bluebird includes a few built-in error types for common usage. All error types have the same identity across different copies of bluebird
module so that pattern matching works in
. All error types have a constructor taking a message string as their first argument, with that message
.message property of the error object.
By default the error types need to be referenced from the Promise constructor, e.g. to get a reference to
var TimeoutError = Promise.TimeoutError. However, for convenience you will probably want to just make the references global.
