Variable: DeltaBaseSubscription

const DeltaBaseSubscription: Handler<(this, id, props) => Promise<DeltaBaseSubscriptionResource>>

Manage a DeltaBase webhook subscription as an Alchemy resource.

v1 is intentionally webhook-only. That matches the stable subscriber shape in the public DeltaBase SDK today and avoids pretending queue or workflow subscribers are production-ready before they are.

Example

import { DeltaBaseSubscription } from '@delta-base/alchemy';

await DeltaBaseSubscription('users-projection', {
  baseUrl: process.env.DELTABASE_URL ?? 'https://api.delta-base.com',
  apiKey: process.env.DELTABASE_API_KEY ?? '',
  eventStoreName: 'auth-service',
  eventFilter: ['user.created', 'user.deleted'],
  webhook: {
    url: 'https://example.com/api/projections/users/events',
    headers: {
      Authorization: `Bearer ${process.env.PROJECTION_AUTH_TOKEN ?? ''}`,
    },
  },
});
