@cch137/shuttle v0.2.8

@cch137/shuttle

Overview

@cch137/shuttle is a lightweight TypeScript library designed for efficient serialization and deserialization of complex data structures. It supports various data types including numbers, strings, arrays, objects, sets, maps, and more. Shuttle also provides optional encryption and MD5 hashing for data integrity and security.

Features

• Number and BigInt Encoding/Decoding: Supports various numeric types like Float32, Float64, Int8, Int16, Int32, Uint8, Uint16, Uint32, BigInt64, and BigUint64.
• String Encoding/Decoding: Efficiently encodes and decodes strings.
• Complex Data Structures: Supports arrays, objects, sets, and maps.
• Binary Data: Handles Uint8Array, Uint16Array, and Uint32Array.
• Date Handling: Encodes and decodes date objects, including handling invalid dates.
• Optional Encryption: Provides encryption and decryption of serialized data using salts.
• MD5 Hashing: Ensures data integrity with optional MD5 hashing.

Installation

npm install @cch137/shuttle

Usage

Importing the Library

import Shuttle from "@cch137/shuttle";

Serialize

const data = {
  name: "John Doe",
  age: 30,
  scores: [95, 87, 92],
  details: {
    married: false,
    address: "123 Main St",
  },
  bigNumber: BigInt("12345678901234567890"),
  birthDate: new Date("1990-01-01"),
};

const serializedData = Shuttle.serialize(data, {
  encoding: "utf-8",
  md5: true,
  salts: [12345],
});

Parse

const deserializedData = Shuttle.parse(serializedData, options);
console.log(deserializedData);

API

Shuttle.serialize(data: any, options?: ShuttleOptions & { salts?: number[] }): Uint8Array

Serializes the input data into a Uint8Array.

• data: The data to serialize.
• options: Optional settings.
  • encoding: The string encoding to use (default: utf-8).
  • md5: Whether to use MD5 hashing (default: false).
  • salts: An array of salts for encryption.

Shuttle.parse<T>(data: Uint8Array, options?: ShuttleOptions & { salts?: number[] }): T

Deserializes the input Uint8Array back into the original data.

• data: The serialized data to parse.
• options: Optional settings.
  • encoding: The string encoding to use (default: utf-8).
  • md5: Whether to verify data integrity using MD5 hashing (default: false).
  • salts: An array of salts for decryption.

Data Types

Shuttle supports the following data types:

• Primitive Types: null, undefined, boolean, number, bigint, string.
• Complex Types: Array, Object, Set, Map, Date.
• Binary Data: Uint8Array, Uint16Array, Uint32Array.

Example

import Shuttle from "@cch137/shuttle";

const originalData = {
  name: "Alice",
  age: 25,
  friends: ["Bob", "Charlie"],
  scores: new Set([100, 98, 95]),
  metadata: new Map([
    ["key1", "value1"],
    ["key2", "value2"],
  ]),
  birthDate: new Date("1995-12-17"),
  bigIntVal: BigInt("9876543210987654321"),
};

const options = {
  encoding: "utf-8",
  md5: true,
  salts: [54321],
};

// Serialize the data
const serializedData = Shuttle.serialize(originalData, options);

// Deserialize the data
const deserializedData = Shuttle.parse(serializedData, options);

console.log(deserializedData);
