JBOS

JavaScript Binary Object Serializer

JBOS is a simple object serializer for JavaScript.

A usecase for JBOS is when you have an insane amount of data, it is more efficient than JSON.

API

Saving an object to a file

// Import JBOS
const jbos = require('jbos');

// Create an object
var serializeMe = {
    array: [
        true,
        false,
        "yes",
        12,
        345,
        678.9,
        null
    ]
};

// Serialize
jbos.writeFile("serialized.jbos", serializeMe);

Loading content from a file

// Import JBOS
const jbos = require('jbos');

// Serialize
var deserialized = jbos.readFile("serialized.jbos");

// Debug
console.log(deserialized);

Format Specification

⚠ TECHNICAL NONSENSE AHEAD - YOU DON'T NEED TO KNOW THIS TO USE IT ⚠

// Please note this is all little endian
// This is also pseudocode and problably not valid C

struct File {
    byte[4] magic; // 4A 42 4F 53
    Object object;
}

struct Object {
    char type;

    if (type == "G") { 
        // null 
    } else if (type == "D") {

        int itemCount;
        DictionaryItem[itemCount] contents;
    } else if (type == "A") {

        int itemCount;

    } else if (type == "S") {

        int stringLength;
        char[stringLength] contents;
    } else if (type == "N") {
