Install

npm i @nestjs-crud/util

Usage

@nestjs-crud/util provides tiny type-guard utilities (isNil, isArrayFull, isObject, etc.) used across the other @nestjs-crud/* packages. Most consumers will never import this directly — it's pulled in transitively by @nestjs-crud/core and the adapter packages.

import { isNil, isArrayFull } from '@nestjs-crud/util';

if (!isNil(value)) {
  // value is non-null and non-undefined
}

if (isArrayFull(items)) {
  // items is an array with at least one element
}
