Based on the Rails TextHelper.

> excerpt('This is an example', 'an', 5);
'...s is an exam...'

Extracts an excerpt from text that matches the first instance of phrase. The radius option expands the excerpt on each side of the first occurrence of phrase by the number of characters defined in radius (which defaults to 100). If the excerpt radius overflows the beginning or end of the text, then the ending option (which defaults to “…”) will be prepended/appended accordingly. If the phrase isn’t found, the original text is returned.

Installation

$ npm install excerpt
$ component install component/excerpt

API

excerpt(text, phrase, radius, ending)

excerpt(example, 'an', 5).should.equal('...s is an exam...');
excerpt(example, 'is', 5).should.equal('This is a...');
excerpt('This is also an example', 'an', 8, '<chop> ').should.equal('<chop> is also an example');
