Package Exports

@stdlib/array-to-json
@stdlib/array-to-json/dist
@stdlib/array-to-json/dist/index.js
@stdlib/array-to-json/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/array-to-json) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

typedarray2json

Return a JSON representation of a typed array.

Installation

npm install @stdlib/array-to-json

Usage

var typedarray2json = require( '@stdlib/array-to-json' );

typedarray2json( typedarray )

Returns a JSON representation of a typed array.

var Float64Array = require( '@stdlib/array-float64' );

var arr = new Float64Array( [ 5.0, 3.0 ] );

var json = typedarray2json( arr );
/* returns
    {
        'type': 'Float64Array',
        'data': [ 5.0, 3.0 ]
    }
*/

For guidance on reviving a JSON-serialized typed array, see reviver().

Notes

Supported typed array types:

The implementation provides basic support for custom typed arrays and sets the type field to the closest known typed array type.

class CustomArray extends Float64Array() {
    constructor( data ) {
        super( data );
    }
}

var arr = new CustomArray( [ 5.0, 3.0 ] );

var json = typedarray2json( arr );
/* returns
    {
        'type': 'Float64Array',
        'data': [ 5.0, 3.0 ]
    }
*/
