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-diffThis 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'}
