CustomDomain

Source: src/Prisma/CustomDomain.ts

A Prisma app custom domain.

Domains can only attach to Apps on the project’s current default branch. Creating this resource starts asynchronous DNS and certificate provisioning; configure the returned dnsRecords and inspect status, foundryStatus, and failureReason before routing production traffic.

App and hostname changes are intentionally rejected because the Management API cannot replace a live domain atomically. Create a second resource, verify DNS and TLS, cut traffic over, and then remove the old resource.

Creating a Custom Domain

const domain = yield* Prisma.CustomDomain("api-domain", {
  app: api.appId,
  hostname: "api.example.com",
});
