Install

Requires Node.js 22.12.0 or later. This package has no dependencies of its own and would run on older releases; the floor is uniform across every @nestjs-crud package so a consumer installing any of them gets one Node requirement rather than several. The packages that integrate with NestJS set the floor: NestJS 12 ships as ESM only, and they are CommonJS, so they load it through Node's require()-of-ESM support, which lands at 22.12.0.

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
}
