CDN Usage

How to load UtilsJS via CDN (jsDelivr & unpkg) with browser support notes.

Using via CDN

You can use UtilsJS on any browser environment through CDN delivery.
This is ideal for:

  • Rapid prototyping.
  • Small client-only projects.
  • Loading utilities without installing NPM packages.
  • Embedding UtilsJS in static HTML sites.

CDN bundles include the full library (minified & browser-ready), and expose a global namespace.

Available CDN Providers

UtilsJS is available on major CDNs with automatic cache-busting and version pinning support.

With jsDelivr

<script src="https://cdn.jsdelivr.net/npm/@rzl-zone/utils-js@latest"></script>

With unpkg

<script src="https://unpkg.com/@rzl-zone/utils-js@latest"></script>

Global Browser Access

Once loaded, the library becomes available via:

window.RzlUtilsJs;

or directly:

RzlUtilsJs.toKebabCase("Hello World");

This allows usage without ES modules, imports, or bundlers.

Pin a specific version to avoid unexpected updates:

<script src="https://cdn.jsdelivr.net/npm/@rzl-zone/utils-js@3.11.0"></script>

Or use a semver major range:

<script src="https://cdn.jsdelivr.net/npm/@rzl-zone/utils-js@3"></script>

Important Notes

When using UtilsJS via CDN, keep the following in mind:

  • Load the CDN script before your own scripts, so the global namespace is ready.
  • Some utilities are Node.js-only and will not work in the browser:
    • Tailwind utilities.
    • Next.js helpers.
    • Any function requiring filesystem, process, or server context.
  • The CDN bundle is ~350 KB (minified) because it contains the entire library.
  • For production usage, NPM installation is strongly recommended:
    • Allows tree-shaking to remove unused utilities.
    • Reduces bundle size dramatically.
    • Enables full TypeScript type inference.
    • Supports modern module resolution (ESM).

When Should You NOT Use the CDN Version?

Avoid CDN usage for:

  • Large SPA projects.
  • Server-side rendering (Next.js, React Router Remix, Nuxt, etc).
  • Codebases requiring strict type-safety.
  • Environments with limited bandwidth.

For these cases, prefer installing via NPM instead of CDN.
