ITSA Utilities
itsa-utils is a collection of basic utility functions designed for JavaScript environments, supporting both server-side (Node.js) and client-side (browser) usage, making it an isomorphic module. It is part of a broader 'itsa' community project aimed at developing highly tested, well-documented, and performant CommonJS modules. The package is currently at version 1.4.3 and was last published over 8 years ago, indicating it is no longer actively maintained. While originally intended to provide a robust set of common helpers, its key differentiator at the time was its isomorphic design within the 'itsa' ecosystem, emphasizing reusability across different JavaScript environments. Given its age, it relies on CommonJS module patterns and does not natively support modern ESM syntax or TypeScript.
Common errors
-
TypeError: itsaUtils.someFunction is not a function
cause The specific utility function you are trying to call may not exist, or the package might structure its exports differently than expected (e.g., requiring a sub-module instead of accessing a property on the main export).fixConsult any available documentation for the exact API of `itsa-utils` functions. If documentation is unavailable, inspect the `itsaUtils` object after requiring it (e.g., `console.log(Object.keys(itsaUtils));`) to discover available methods. -
Error [ERR_REQUIRE_ESM]: require() of ES Module ... not supported. Instead change the require of ... to a dynamic import()
cause This error indicates that you are attempting to `require()` an ES Module in a context where it's not supported, or more likely, you are trying to use `itsa-utils` (a CJS module) in a modern ESM-only context.fixEnsure your project is configured for CommonJS compatibility if you intend to use this package. For new projects, it's recommended to choose a modern, actively maintained utility library that supports ESM.
Warnings
- breaking The itsa-utils package appears to be abandoned. Its last publication was over 8 years ago (as of 2026), meaning it receives no new features, bug fixes, or security updates. This poses significant risks for new projects or ongoing maintenance.
- gotcha This package is CommonJS-only. Attempting to use ES module `import` syntax will result in errors in most modern Node.js environments without specific configuration, and it is not designed for direct browser ES module usage.

Imports
- itsa-utils
import * as utils from 'itsa-utils'; import { isString } from 'itsa-utils';const utils = require('itsa-utils');
Quickstart
const itsaUtils = require('itsa-utils');
// Illustrative usage of some common utility patterns.
// (Specific function names are illustrative as API details are not readily available)
const myString = 'hello world';
const myNumber = 123;
const myObject = { a: 1, b: { c: 2 } };
// Example 1: Type checking (illustrative function)
if (itsaUtils.isString && itsaUtils.isString(myString)) {
console.log(`'${myString}' is a string.`);
}
// Example 2: Object manipulation (illustrative function)
const clonedObject = itsaUtils.deepClone ? itsaUtils.deepClone(myObject) : { ...myObject };
console.log('Cloned object:', clonedObject);
// Example 3: Array utility (illustrative function)
const ensureArray = itsaUtils.toArray || ((val) => Array.isArray(val) ? val : [val]);
const arr1 = ensureArray(myNumber);
const arr2 = ensureArray([1, 2, 3]);
console.log('Ensured array 1:', arr1);
console.log('Ensured array 2:', arr2);
console.log('ITSA Utilities loaded successfully.');
