Usage

var serialize = require( 'eval-serialize-date' );

serialize( value )

Serializes a Date object for dynamic code evaluation.

var date = new Date();
 
var str = serialize( date );
// returns 'new Date(<timestamp>)'
 
var d = eval( str );
// returns <Date>
 
var bool = ( date.getTime() === d.getTime() );
// returns true

serialize.raw( date )

Serializes a Date object 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 Date() );
// returns 'new Date(<timestamp>)';

Examples

var serialize = require( 'eval-serialize-date' );
 
/**
* Returns a function to create a Date filled array.
*/
function create( date ) {
    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( date ) + ';';
    f += '}';
    f += 'return arr;';
    f += '}';
    return ( new Function( f ) )();

var fill = create( new Date() );
 
console.log( fill( 10 ) );
