Modify or review @alexasomba/better-auth-paystack database schema behavior. Use for paystackProduct, paystackPlan, paystackTransaction, subscription, user.paystackCustomerCode, organization.paystackCustomerCode/email, Better Auth schema overrides, mergeSchema behavior, migrations, indexes, unique fields, and backward-compatible table or field changes.

Schema Contract

The plugin contributes Better Auth schema through getSchema(options).

Always included:

  • user.paystackCustomerCode
  • paystackTransaction
  • paystackProduct
  • paystackPlan

Included when subscription.enabled is true:

  • subscription

Included when organization.enabled is true:

  • organization.paystackCustomerCode
  • organization.email

Product and plan tables are intentionally always present. Do not make them optional in a compatibility-preserving release.

Core Patterns

Use schema overrides only for Better Auth-supported customization

Consumers can pass options.schema and the plugin merges it with the default schema via mergeSchema. Use this for model/field naming and migration metadata, not for removing core billing state.

When subscriptions are disabled, getSchema strips a user-provided subscription override before merging so the subscription model is not reintroduced accidentally.

Preserve field compatibility

Schema changes affect persisted billing state. Treat these as migration-sensitive:

  • changing required fields
  • changing uniqueness or indexes
  • renaming paystack* identity fields
  • changing transaction reference uniqueness
  • changing subscription paystackSubscriptionCode uniqueness
  • changing product/plan paystackId or planCode uniqueness

Prefer additive optional fields in minor releases. Required field changes need clear migrations and major-version scrutiny.

Keep TypeScript schema exports aligned

PaystackPluginSchema, individual schema exports, and PaystackOptions["schema"] should stay in sync. If a field is added to a schema table, update the corresponding TypeScript table type in src/schema.ts.

Common Mistakes

Removing catalog tables when products are unused

The package supports catalog sync and discovery. paystackProduct and paystackPlan remain part of the plugin schema even if a specific app only uses subscriptions or only uses transactions.

Reintroducing subscription schema when subscriptions are disabled

Keep the guard in getSchema that removes options.schema.subscription unless subscription.enabled is true.

Forgetting organization schema conditions

Organization billing fields should only be added when organization.enabled is true.

Verification

Run schema and type tests after schema changes:

shell
vp test test/paystack.test.ts test/typesafety.test.ts
vp check
