word-diff is a word based inline string diff library, based on John Resig's Javascript Diff Algorithm. Focus is put on producing comprehensible diff instead of a compact one. The diff consists of the minimal count of items describing changes in the string. Both the original and the changed string can be reproduced from the diff. Whitespace-only differences are ignored.

 $ [sudo] npm install word-diff

This module can be used to generate word based diff for two strings.

 var worddiff = require('word-diff'); worddiff.diffString( 'what a great time to be alive', 'how great it is to be alive' ) // returns: [ {'remove': 'what a ', 'add': 'how '}, {'text': 'great '}, {'remove': 'time ', 'add': 'it is '}, {'text': 'to be alive'} ]
