Prepare Array For Prisma

A utility that will take regular arrays from forms and adapt them to work with prisma. It also works with nested arrays.

Get Started

yarn add @creatorsneverdie/prepare-array-for-prisma

import {prepareArrayField} from "@creatorsneverdie/prepare-array-for-prisma"

How To

prepareArrayField() takes 4 parameters:

1. Form values as any[]
2. Initial database data as any[]
3. Mapper as ((item: any, initial?: any) => any)
4. Options as { removedItemsMethod: 'disconnect' | 'delete'}

You use the function like this:

const value = [ {name: 1}, {id: 2, name: 3} ]
const initial = [ {id: 2, name: 2}, {id: 3} ]

const mappedArray = prepareArrayField(value, initial, (item) => ({
  ...item,
}))

You can also set options object for handling removing elements. You can choose to either delete the element from the database completely, or disconnect. By default the option is set to disconnect:

const mappedArray = prepareArrayField(value, initial, (item) => ({
  ...item,
}), {removedItemsMethod: "delete" })

Then inside a prisma operation:

  const updateUser = await prisma.project.update({
    where: {
      id: 1
    },
    data: {
      title: 'test project update',
      users: mappedArray
    }
  })
