JSONEXT

JSONEXT is an extension to JSON that preserves the data type of typed arrays and BigInts.

Installation

npm i @j-o-r/jsonext --save

Usage

Stringify

To stringify an object with typed arrays:

import JSONEXT from '@j-o-r/jsonext'
const typedArray = new Float32Array([1.1, 2.2, 3.3]);
const jsonString = JSONEXT.stringify({ array: typedArray });
console.log(jsonString); // Output: {"array":{"_dT_":"f32a","_dA_":[1.1,2.2,3.3]}}

Parse

To parse a JSON string back into its original form:

const parsedObject = JSONEXT.parse(jsonString);
console.log(parsedObject.array instanceof Float32Array); // true

Features

• Typed Arrays: Preserves the type of arrays like Float32Array, Int8Array, etc.
• BigInt: Converts BigInt to string representation for JSON compatibility.
• Compatibility: Works with standard JSON methods but extends functionality.

Limitations and Notes:

• Ensure that the _dT_ and _dA_ keys do not conflict with your data keys.
• Performance might be impacted for large objects due to type checking.
• Default handling for handling known types in parsing.
