Use when scanning NestJS providers with DiscoveryService-backed utilities.
Use when working with the @wisemen/nestjs-custom-fields package — developer-defined custom fields in NestJS with TypeORM persistence and runtime validation. Covers registering the CustomFieldDefinition entity, authoring definitions with customFieldDefinition(), storing resolved values via @CustomFieldValueColumn(), exposing them through CustomFieldValueDto / @IsCustomFields(), and validating submissions with CustomFieldDefinitionsRepository + validateCustomFieldValues(). Use this whenever a task involves custom field definitions, CustomFieldValue columns, custom-field DTOs, or tenant-scoped field definitions, even if the package is not named explicitly.
Use when defining Typesense collections, collectors, and search queries in NestJS APIs.
Generate PDFs through API2PDF in NestJS. Use when converting HTML or URLs to PDFs in apis.
Use when storing and validating multilingual text in NestJS apis with TypeORM and class-validator.
Use when configuring NATS messaging, subscribers, or the simple NatsClient in NestJS applications.
