Fast and correct clip functions for HTML and plain text.

Build Status text-clipper on NPM

Written by Arend van Beelen jr. @ Speakap.

Why use text-clipper?

text-clipper offers the following advantages over similar libraries that allow clipping HTML:

  • Correctness
    • HTML is processed through a proper state machine, no regular expression hacks.
    • Valid HTML input always produces valid HTML output.
    • Heavily unit-tested to support the above statement.
  • Proper Unicode handling
    • Unicode-awareness makes sure Unicode characters such as emojis don't get clipped halfway.
  • Performance
    • Text-clipper has been carefully optimized and is typically as fast as or faster than its competitors (see: blog).
  • Consistent API and behavior for both HTML and plain text


Make sure you have Node.js installed and run:

$ npm install text-clipper


Basic example:

var clip = require('text-clipper');
var clippedString = clip(string, 80); // returns a string of at most 80 characters

You can also specify options:

var clippedHtml = clip(htmlString, 140, { html: true, maxLines: 5 });



By default, text-clipper tries to break only at word boundaries so words don't get clipped halfway. Set this option to true if you want words to be broken up.


By default, text-clipper treats the input string as plain text. This is undesirable if the input string is HTML, because it might result in broken HTML tags. Set this option to true to make text-clipper treat the input as HTML, in which case it will try to always return valid HTML, provided the input is valid as well.


The amount of characters to assume for images. This is used whenever an image is encountered, but also for embedded SVG and MathML content. The default is 2.


The string to insert to indicate the string was clipped. Default: '…'.

Note the indicator is only inserted when the clipping doesn't occur at a line-break.


Maximum amount of lines allowed. If given, the string will be clipped either at the moment the maximum amount of characters is exceeded or the moment maxLines newlines are discovered, whichever comes first.

Note when in HTML mode, block-level elements trigger newlines and text-clipper assumes the text will be displayed with a CSS white-space setting that treats \n as a line break. Of course the HTML tag <br> is also counted.


npm i text-clipper
