eval-serialize-typed-array v1.0.1
Typed Array Serialization
Serializes a typed array for dynamic code evaluation.
Installation
$ npm install eval-serialize-typed-array
Usage
var serialize = require( 'eval-serialize-typed-array' );
serialize( value )
Serializes a typed array
for dynamic code evaluation.
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.
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
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,
$ node ./examples/index.js
Tests
Unit
Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:
$ make test
All new feature development should have corresponding unit tests to validate correct functionality.
Test Coverage
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:
$ make test-cov
Istanbul creates a ./reports/coverage
directory. To access an HTML version of the report,
$ make view-cov
