PHP's rawurldecode in TypeScript

How to use

Install via yarn add locutus and import: import { rawurldecode } from 'locutus/php/url/rawurldecode'.

Or with CommonJS: const { rawurldecode } = require('locutus/php/url/rawurldecode')

Use a bundler that supports tree-shaking so you only ship the functions you actually use. Vite, webpack, Rollup, and Parcel all handle this. For server-side use this is less of a concern.

Examples

These examples are extracted from test cases that automatically verify our functions against their native counterparts.

#	code	expected result
1	rawurldecode('Kevin+van+Zonneveld%21')	'Kevin+van+Zonneveld!'
2	rawurldecode('https%3A%2F%2Fkvz.io%2F')	'https://kvz.io/'
3	rawurldecode('https%3A%2F%2Fwww.google.nl%2Fsearch%3Fq%3DLocutus%26ie%3D')	'https://www.google.nl/search?q=Locutus&ie='

Notes

• Please be aware that this function expects to decode from UTF-8 encoded strings, as found on pages served as UTF-8
