Why this package exists

Backend, JS client, and React layer all need the same types — DTOs, enums, domain interfaces. This package is the single source of truth so a change to a request/response shape on the server breaks the client at compile time, not at runtime.

It is consumed by:

• @ackplus/nest-auth — NestJS backend module
• @ackplus/nest-auth-client — framework-agnostic JS/TS client
• @ackplus/nest-auth-react — React provider, hooks, guards

You usually don't install it directly — it's a transitive dependency of all three. Install it explicitly when you want to type-check code that consumes the auth API without pulling in the full backend or client package.

Install

pnpm add @ackplus/nest-auth-contracts

Both ESM and CommonJS builds ship in the package. No peer dependencies.

  TenantModeEnum,

  // Request/response DTOs
  ILoginRequest,

Naming conventions

• Domain entities → INestAuth{Entity} (e.g. INestAuthUser, INestAuthRole)
• Enums → NestAuth{Name}Enum (e.g. NestAuthMFAMethodEnum)
• Request DTOs → I{Feature}Request
• Response DTOs → I{Feature}Response
• Configuration → I{Feature}Config or I{Feature}Options
