@ltikit/adapter-prisma

Prisma PlatformStore + NonceStore for LTIkit — works against any Prisma-supported database (SQLite, Postgres, MySQL, ...). Bring your own Prisma schema; this adds two small models and maps them to the core stores.

Requires @ltikit/core.

npm i @ltikit/core @ltikit/adapter-prisma

1. Add the models

Copy the two models from prisma/schema.example.prisma into your own schema.prisma, then migrate:

npx prisma migrate dev --name add_ltikit

2. Wire the stores

import { PrismaClient } from '@prisma/client'
import { createLti, staticKeyStore } from '@ltikit/core'
import { prismaPlatformStore, prismaNonceStore } from '@ltikit/adapter-prisma'

const prisma = new PrismaClient()

export const lti = createLti({
  keys: staticKeyStore({ /* ...your tool keypair... */ }),
  platforms: prismaPlatformStore(prisma),
  nonces: prismaNonceStore(prisma),
})

No hard dependency on @prisma/client: the client is accepted structurally (PrismaLike — just the ltiPlatform / ltiNonce delegates), so any generated PrismaClient whose schema matches the two models above satisfies it automatically.

Notes

• Single-use nonces are enforced by Prisma's per-row atomic delete — a replayed state hits a missing row (Prisma's P2025), which consume turns into null.
• Also implements the writable MutablePlatformStore contract, so Dynamic Registration auto-persists new platforms with no manual insert.
• Different model names? Pass an object matching PrismaLike that aliases your own delegates: prismaPlatformStore({ ltiPlatform: prisma.myModel, ltiNonce: prisma.myOtherModel }).
