@sanity/diff

What is @sanity/diff?

@sanity/diff is a JavaScript library designed to compute and represent differences between two JSON documents. It is particularly useful for applications that need to track changes in data structures, such as content management systems or collaborative editing tools.

What are @sanity/diff's main functionalities?

Compute Differences

This feature allows you to compute the differences between two JSON documents. The `diff` function takes two objects and returns an object representing the changes.

const { diff } = require('@sanity/diff');

const oldDoc = { name: 'Alice', age: 30 };
const newDoc = { name: 'Alice', age: 31 };

const differences = diff(oldDoc, newDoc);
console.log(differences);

Patch Application

This feature allows you to apply a patch to a JSON document. The `applyPatch` function takes an original object and a patch object, and returns the updated object.

const { applyPatch } = require('@sanity/diff');

const oldDoc = { name: 'Alice', age: 30 };
const patch = { age: 31 };

const newDoc = applyPatch(oldDoc, patch);
console.log(newDoc);

Visual Representation

This feature allows you to get a visual representation of the differences between two JSON documents. The `formatDiff` function takes the differences object and returns a human-readable string.

const { diff, formatDiff } = require('@sanity/diff');

const oldDoc = { name: 'Alice', age: 30 };
const newDoc = { name: 'Alice', age: 31 };

const differences = diff(oldDoc, newDoc);
const formattedDiff = formatDiff(differences);
console.log(formattedDiff);

Other packages similar to @sanity/diff

diff

The `diff` package is a popular library for computing differences between two strings or objects. It provides a variety of diff algorithms and can be used for text, JSON, and other data structures. Compared to @sanity/diff, it offers more flexibility in terms of diff algorithms but may require more configuration.

deep-diff

The `deep-diff` package is another library for comparing the differences between two JavaScript objects. It provides a simple API for finding differences and applying patches. While it is similar to @sanity/diff in functionality, it may not offer the same level of integration with Sanity's ecosystem.

jsondiffpatch

The `jsondiffpatch` package is designed specifically for comparing JSON documents and applying patches. It offers a rich set of features, including visual diffing and patching. Compared to @sanity/diff, it provides more advanced features for JSON-specific use cases but may be more complex to use.
