[Question] Can I use numeric value for cursor??

[JaeWangL]

import { findManyCursorConnection } from '@devoxa/prisma-relay-cursor-connection'

interface TestObject {
  id: number;
}

const result = await findManyCursorConnection<TestObject, TestObject>(
  (args) => tests.findMany(args),
  () => tests.count(),
  { first: {first}, after: {after} }
)

I want use numeric value for unique value
For that, I set my own TestObject type when using findManyCursorConnection
But, after is always needed string value
Can I use numeric unique?

Hey :) Relay uses cursor-based pagination, where the cursor is opaque. This means you can't pass in a number as-is.

However, you can still use your own encoder and decoder for the cursor: https://github.com/devoxa/prisma-relay-cursor-connection/tree/1ad12bb1645350943c850b7b8d78f6254de9f1ad#custom-cursors

So for your example it would be something like this:

import { findManyCursorConnection } from '@devoxa/prisma-relay-cursor-connection'

interface TestObject {
  id: number;
}

const result = await findManyCursorConnection<TestObject, TestObject>(
  (args) => tests.findMany(args),
  () => tests.count(),
  { first: first, after: after },
  {
    getCursor: (record) => ({ id: record.id }),
    encodeCursor: (cursor) => Buffer.from(JSON.stringify(cursor)).toString('base64'),
    decodeCursor: (cursor) => JSON.parse(Buffer.from(cursor, 'base64').toString('ascii')),
  }
)

• first is the number of records you want (e.g. 5)
• after is a base64-encoded JSON of the cursor (e.g. { id: 12 })

Hope this answers your question!
