Url Utils

Url Utils provides helpers for URL handling. Use it when you need to detect whether a URL is already encoded (e.g. before deciding to encode or decode) or to avoid double-encoding.

Import

import { isEncoded } from '@js-smart/react-kit';

Basic usage

isEncoded('hello');           // false
isEncoded('hello%20world');   // true
isEncoded('a%2Bb');           // true

With query or path building

const raw = searchParams.get('q');
if (raw && !isEncoded(raw)) {
  // safe to encode for use in another URL
  const encoded = encodeURIComponent(raw);
}

Notes

• Uses decodeURIComponent(url) and compares the result to the original. If decoding changes the string, the URL is considered encoded.
• If decodeURIComponent throws (e.g. malformed encoding), the function returns false.
