OrderMergeStrategy
OrderMergeStrategy
An OrderMergeStrategy defines what happens when a Customer with an existing Order signs in with a guest Order, where both Orders may contain differing OrderLines.
Somehow these differing OrderLines need to be reconciled into a single collection of OrderLines. The OrderMergeStrategy defines the rules governing this reconciliation.
info
This is configured via the orderOptions.mergeStrategy property of
your VendureConfig.
