deleteItem()

The deleteItem() mutation is simple. GraphQL and the database do the work for us.

// src/mutations.ts export const deleteItem = async (_: any, args: { id: string }) => { // DynamoDB handles deleting already deleted objects, no error :) const item = await db.deleteItem({ TableName: process.env.ITEM_TABLE!, Key: { itemId: args.id, }, ReturnValues: "ALL_OLD", }) return remapProps(item.Attributes) }

We take the id from mutation arguments, ask our database to delete the row, and return the old attributes.
