BillingInProcess

Every paykit binding, implemented in the process that hosts the model.

Source: packages/paykit/src/Billing/BillingInProcess.layer.ts Kind: Layer · Product: Usage · Provides: Paykit.TrackUsage

Every paykit binding, implemented in the process that hosts the model.

One layer for the whole tenant surface, because the clearance is the Api’s and not the operation’s: a deployment that provides this layer can send exactly the commands BillingApi serves, and nothing an operator can.

Provide it beside the store, the catalog and the payments router. Swap it for BillingApiLayer to host the model in a different service — no call site changes.

Providing the tenant surface

const World = Layer.mergeAll(
  BillingInProcess,
  catalogLayer(Catalog),
  paymentsRouter(provider),
);

fetch: Effect.gen(function* () {
  const trackUsage = yield* Paykit.TrackUsage(account);
  yield* trackUsage({ featureId: "messages", value: 1, idempotencyKey: requestId });
});
