PHP's rawurldecode in JavaScript

How to use

You you can install via yarn add locutus and require this function via const rawurldecode = require('locutus/php/url/rawurldecode').

It is important to use a bundler that supports tree-shaking so that you only ship the functions that you actually use to your browser, instead of all of Locutus, which is massive. Examples are: Parcel, webpack, or rollup.js. For server-side use this is typically less of a concern.

Examples

Please note that these examples are distilled from test cases that automatically verify our functions still work correctly. This could explain some quirky ones.

#	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

Here’s what our current JavaScript equivalent to PHP's rawurldecode looks like.

module.exports = function rawurldecode(str) {

  return decodeURIComponent(
    (str + '').replace(/%(?![\da-f]{2})/gi, function () {
      // PHP tolerates poorly formed escape sequences
      return '%25'
    }),
  )
}

A community effort

Not unlike Wikipedia, Locutus is an ongoing community effort. Our philosophy follows The McDonald’s Theory. This means that we assimilate first iterations with imperfections, hoping for others to take issue with-and improve them. This unorthodox approach has worked very well to foster fun and fruitful collaboration, but please be reminded to use our creations at your own risk. THE SOFTWARE IS PROVIDED "AS IS" has never been more true than for Locutus.
