> Serializes a typed array for dynamic code evaluation.

Installation

`` bash
$ npm install eval-serialize-typed-array
`

Usage

` javascript
var serialize = require( 'eval-serialize-typed-array' );
`

#### serialize( value )

Serializes a typed array for dynamic code evaluation.

` javascript
var deepEqual = require( 'deep-equal' );

var arr1 = new Int8Array( 4 );

var str = serialize( arr1 );
// returns 'new Int8Array([0,0,0,0])'

var arr2 = eval( str );
// returns Int8Array( [0,0,0,0] )

var bool = deepEqual( arr1, arr2 );
// returns true
`


#### serialize.raw( arr )

Serializes a typed array without performing type checking.

` javascript
try {
// throws during input argument validation...
serialize( null );
} catch ( err ) {
console.error( err );
}

// To bypass validation...
var str = serialize.raw( new Float64Array( [1,2,3,4] ) );
// returns 'new Float64Array([1,2,3,4])';
`

Examples

` javascript
var serialize = require( 'eval-serialize-typed-array' );

/**
* Returns a function to create a filled array.
*/
function create( arr ) {
var f = '';
f += 'return function fill( len ) {';
f += 'var arr = new Array( len );';
f += 'for ( var i = 0; i < len; i++ ) {';
f += 'arr[ i ] = ' + serialize( arr ) + ';';
f += '}';
f += 'return arr;';
f += '}';
return ( new Function( f ) )();
}

var fill = create( new Float32Array( 20 ) );

console.log( fill( 10 ) );
`

To run the example code from the top-level application directory,

` bash
$ node ./examples/index.js
`

Tests

$3

Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:

` bash
$ make test
`

All new feature development should have corresponding unit tests to validate correct functionality.

$3

This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:

` bash
$ make test-cov
`

Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,

` bash
$ make view-cov
