Buffer Serialization

Serializes a Buffer object for dynamic code evaluation.

Installation

$ npm install eval-serialize-buffer

Usage

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

serialize( value )

Serializes a Buffer object for dynamic code evaluation.

var deepEqual = require( 'deep-equal' );
 
var b1 = new Buffer( 'beep' );
 
var str = serialize( b1 );
// returns 'new Buffer("YmVlcA==","base64")'
 
var b2 = eval( str );
// returns Buffer( 'beep' )
 
var bool = deepEqual( b1, b2 );
// returns true

serialize.raw( buffer )

Serializes a Buffer 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 Buffer( 'boop' ) );
// returns 'new Buffer("Ym9vcA==","base64")';

Examples

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