A small, useful utility collection for JavaScript/ESM projects — includes string helpers, DOM utilities, and a simple localStorage-based caching system.

npm install @apsonex/js-utils

Or using Yarn:

yarn add @apsonex/js-utils

import {
  JsCache,
  str,
  bodyScrollEnable,
  bodyScrollDisable,
  isIframe,
  loadScript,
  loadStyle,
} from '@apsonex/js-utils';

Powerful string helper chainable class.

str("hello world").kebab().toString(); // "hello-world"
str("some/filename.txt").afterLast("/").toString(); // "filename.txt"
str("html content").minifyHtml(); // removes whitespace, comments

Chainable methods:

• after, afterLast, before, beforeLast
• kebab, camel, snake, slug, plural, singular
• replaceFirst, replaceLast, replaceArray
• limit, words, start, finish
• contains, containsAll, is, startsWith, endsWith
• title, minifyHtml, explode

Simple localStorage cache with TTL (time to live) support.

const cache = new JsCache().init({ prefix: 'my_app:' });

cache.put('user', { name: 'John' }, '10m');
cache.remember('settings', '1hr', () => fetchSettings());

Supports TTL formats:

• 60s, 10m, 1hr, 1d, 1mo, 1yr, or numeric seconds

Methods:

• put(key, value, ttl)
• remember(key, ttl, fallback)
• get(key)
• has(key)
• forget(key)

Lightweight, useful browser DOM helpers.

bodyScrollDisable(); // disables body scroll
bodyScrollEnable();  // enables it back

isIframe(); // true if running inside iframe

Dynamically load external scripts or stylesheets.

await loadScript('https://example.com/script.js', {
  type: 'module',
  onLoad: () => console.log('loaded'),
  onError: (err) => console.error(err),
});

await loadStyle('https://example.com/style.css', {
  media: 'all',
});

They support:

• Auto-skip if already loaded
• onLoad, onError callbacks
• Custom attributes like crossorigin, media, title

npm run build

Outputs ES module and UMD builds in /dist.
