Example from Prisma-GraphQL integration

Each library has a single responsibility

• libs/api/domain/users DOMAIN

  • data-access DATA LAYER

    • src
      • lib
        • models
          • user-login.input.ts
          • user-token.ts
          • user-register.input.ts
        • api-domain-users-data-access.module.ts
        • users.service.ts
      • index.ts

  • feature API LAYER

    • src
      • lib
        • api-domain-users-feature.module.ts
        • users.resolver.ts
      • index.ts

This is base domain library which holds, in this case, some resolvers.

Contains domain's data layer and exposes:

• ApiGraphqlUsersDataAccessModule
• UsersService
• models

// generate feature lib
nx generate @nrwl/nest:library --name=feature --directory=api/domain/users --buildable --standaloneConfig --strict --tags=type:feature,scope:api --no-interactive

// generate data-access lib
nx generate @nrwl/nest:library --name=data-access --directory=api/domain/users --buildable --standaloneConfig --strict --tags=type:data-access,scope:api --no-interactive

Add feature module name to the domains array.

// libs/api/core/src/lib/registrations/domains.registration.ts 

import { ApiDomainUsersFeatureModule } from '@wwwsolutions/api/domain/users/feature';

export const domains: NestImportsType = [ApiDomainUsersFeatureModule];
