Read your slot

Goal: inspect the slot you created. This step makes no transactions and needs no credential presentation.

Check its state

Copy the reader into the same project:

cp node_modules/tasra-sdk/examples/learning-read-slot.ts .
npx tsc --noEmit
npx tsx learning-read-slot.ts

Open learning-read-slot.ts:

import {savedSlotId, tasra} from './learning-context.js'

const slotId = await savedSlotId()
const slot = await tasra.slots.get(slotId)
console.log('Slot:', slot.slotId)
console.log('Key ready:', slot.ready)
console.log('Key epoch:', slot.epoch)
console.log('Threshold:', slot.threshold)

Success: Key ready: true, followed by the key epoch and threshold. The epoch identifies the slot’s current key generation. k is the required number of key holders; n is the number assigned to the slot.

The slot ID is loaded from your private lesson store. In a larger app, keep your slot IDs with your application records. The application client does not have a slots.list() method.

slots.get() checks that the slot exists and has not been cancelled. To inspect a cancelled slot’s record, use the registry reader shown in the next lesson.
