D1

A Cloudflare D1 billing database.

Source: packages/paykit/src/Database/D1.ts Kind: Layer · Product: D1 · Provides: paykit/Database · Peer dependencies: @alchemy.run/cloudflare

A Cloudflare D1 billing database.

At runtime the Worker reaches the database through its native binding (the layer pulls in Cloudflare.D1.QueryDatabaseBinding). At migration time the deploy uses the D1 HTTP query API — which also targets the local simulator under alchemy dev — so the Worker’s binding is never used outside the runtime, and the migration code is tree-shaken out of the deployed bundle. The structure is Alchemy’s own CloudflareD1 layer for Better Auth, with paykit’s executor in place of the Kysely one.

Import it from @potion.run/paykit/Database/D1, not the barrel: it carries @alchemy.run/cloudflare, an optional peer.

A D1-backed model

const Db = Cloudflare.D1.Database("BillingDb");

Effect.gen(function* () {
  const stack = yield* Paykit.BillingStack("Billing", { ...billing, migrate: true });
  return { tiers: stack.tiers };
}).pipe(Effect.provide(D1(Db)));
