Safely remove repeating whitespace from HTML text.
npm install normalize-html-whitespace> Safely remove repeating whitespace from HTML text.
Using \s to normalize HTML whitespace will strip out characters that are actually rendered by a web browser. Such would be classified as a lossy change and would produce a different visual result. This package will collapse multiple whitespace characters down to a single space, while ignoring the following characters:
* \u00a0 or (non-breaking space)
* \ufeff or (zero-width non-breaking space)
…as well as these lesser-known ones:
* \u1680 or (Ogham space mark)
* \u180e or (Mongolian vowel separator)
* \u2000 or (en quad)
* \u2001 or (em quad)
* \u2002 or (en space)
* \u2003 or (em space)
* \u2004 or (three-per-em space)
* \u2005 or (four-per-em space)
* \u2006 or (six-per-em space)
* \u2007 or (figure space)
* \u2008 or (punctuation space)
* \u2009 or (thin space)
* \u200a or (hair space)
* \u2028 or
(line separator)
* \u2029 or
(paragraph separator)
* \u202f or (narrow non-breaking space)
* \u205f or (medium mathematical space)
* \u3000 or (ideographic space)
For the sake of completeness, the following characters which are not part of \s will also not be affected:
* \u200b or (zero-width breaking space)
Note: this package does not contain an HTML parser. It is meant to be used on text nodes only.
