Package Exports

@stdlib/array-to-json

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.

Readme

toJSON

Return a JSON representation of a typed array.

Installation

npm install @stdlib/array-to-json

Usage

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

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

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