# https://jsondiffpatch.com llms.txt jsondiffpatch is an npm package. it compares 2 json (or any 2 objects in javascript or typescript), and get a json diff with the changes. ``` ts import { diff } from "jsondiffpatch"; const delta = diff(left, right); ``` ## features - deep diff json or objects, get a compact json diff delta - use delta to patch - smart array diffing using [LCS](http://en.wikipedia.org/wiki/Longest_common_subsequence_problem), **_IMPORTANT NOTE:_** to match objects inside an array you must provide an `objectHash` function (this is how objects are matched, otherwise a dumb match by position is used). For more details, check [Array diff documentation](docs/arrays.md) - multiple formatters (visual html, jsonpatch, console) - (optionally) uses [google-diff-match-patch](http://code.google.com/p/google-diff-match-patch/) for long text diffs (diff at character level) - reverse a delta, unpatch (eg. revert object to its original state using a delta) - simplistic, pure JSON, low footprint [delta format](docs/deltas.md) - multiple output formatters: - html (check it at the [Live Demo](https://jsondiffpatch.com)) - annotated json (html), makes the JSON delta format self-explained - console (colored), try running `./node_modules/.bin/jsondiffpatch left.json right.json` - JSON Patch format RFC 6902 support - write your own! check [Formatters documentation](docs/formatters.md) - BONUS: `jsondiffpatch.clone(obj)` (deep clone) ## links - [github repo](https://github.com/benjamine/jsondiffpatch) - [npm package](https://www.npmjs.com/package/jsondiffpatch)
