fastest-stable-stringify

What is fastest-stable-stringify?

The fastest-stable-stringify npm package is a JavaScript library designed to provide a fast and deterministic JSON.stringify() alternative. It ensures that the output for the same input object is consistent across different runs, which is crucial for tasks like caching and comparison where consistent ordering of object keys is necessary.

What are fastest-stable-stringify's main functionalities?

Deterministic JSON serialization

This feature allows for the serialization of JSON objects in a stable and deterministic manner, meaning the order of object keys is consistent regardless of their insertion order. This is particularly useful for generating consistent hashes of data or caching.

{"const stringify = require('fastest-stable-stringify');\nconst obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };\nconst result = stringify(obj);\nconsole.log(result); // '{"a":3,"b":[{"x":4,"y":5,"z":6},7],"c":8}'"}

Other packages similar to fastest-stable-stringify

json-stable-stringify

This package offers similar functionality to fastest-stable-stringify by providing a deterministic version of JSON.stringify(). It ensures consistent ordering of object keys but is generally slower in performance compared to fastest-stable-stringify.

json-stable-stringify-without-jsonify

Similar to json-stable-stringify, this package provides deterministic JSON serialization. It differs primarily in that it does not include a polyfill for JSON, which can be beneficial in environments where the native JSON is preferred for performance reasons.
