Relay Modern: delete record in optimisticUpdater

Question

In my app I have a mutation where I want to use the optimisticUpdater to update the view before the server response. For that I need to remove some records from a list into the relay store, like that:

optimisticUpdater: storeProxy => {
  storeProxy.delete(recordDataID)
}

The problem is that relay don't remove the record, but it transforms the record in null. This can be annoying because I have to filter the list every time I use it in my app.

Some one know how can I remove the record ? thx

Answer 1

You have to remove your records from the list

optimisticUpdater: (store) => {
    const listOfRecords = store.getRoot().getLinkedRecords('list')
    const newList = listOfRecords.filter(record => record.getDataID() !== recordDataID)
    store.getRoot().setLinkedRecords(newList, 'list')
}

In this example I assume your list is placed at the root of your graph
