SteganoDB

SteganoDB is a lightweight TypeScript library that allows you to store and retrieve data within images using steganography. It lets you embed JSON data into images, providing a creative and secure way to store sensitive information or configurations.

Features

• Simple Interface: Easy-to-use methods to set, get, and manage data within images.
• TypeScript Support: Written in TypeScript but compatible with both TypeScript and JavaScript projects.
• Steganography: Uses steganography techniques to hide JSON data within images.
• Data Concealment: Supports hiding JSON data within images without encryption for quick retrieval.
• Flexible Use: Suitable for various applications, including storing configurations, sensitive data, or small datasets.

Installation

You can install SteganoDB via npm:

npm install stegano.db

Usage

const { SteganoDB } = require('stegano.db');

const db = new SteganoDB('./default.png');

const PlayerOne = {
    nickname: 'Kisakay',
    team: 'red',
    areMod: false,
};

const PlayerTwo = {
    nickname: 'Sown',
    team: 'red',
    areMod: false,
};

db.push('server.players', PlayerOne);
db.push('server.players', PlayerTwo);

console.log(db.get('server.players'));
/*
[
  {
    nickname: "Kisakay",
    team: "red",
    areMod: false,
  }, {
    nickname: "Sown",
    team: "red",
    areMod: false,
  }
]
*/

db.set("server.info", {
    server_name: "Kisakay's Server",
    slot: 3,
    map: 'dust2'
});

console.log(db.get('server'));
/*
{
  players: [
    {
      nickname: "Kisakay",
      team: "red",
      areMod: false,
    }, {
      nickname: "Sown",
      team: "red",
      areMod: false,
    }
  ],
  info: {
    server_name: "Kisakay's Server",
    slot: 3,
    map: "dust2",
  },
}
*/

console.log(db.get('server.info'));
/*
{
    server_name: "Kisakay's Server",
    slot: 3,
    map: "dust2",
}
*/

db.add('server.info.slot', 10);
// Server's slot is now at Current + 10 (3+10) : 13

db.sub('server.info.slot', 2);
// Server's slot is now at Current - 2 (13-2) : 11

db.clear();
// Entirely clear the database !!

db.cache('server.info.lock', true, 3000);
// Lock the server access for 3000 ms; (Erase the value after the time's up)

console.log(db.all());
// Return the entire database

console.log(db.has('server.info.lock'));
// Return true if the value exists

db.delete('server');
// Remove the object/value

db.table('anticheat');
// Create another database in the current directory where the database (png file) is located (a 'table')

Methods

constructor(filePath?: string, options?: any)

Initializes a new instance of the SteganoDB class.

• filePath: Optional. The path to the image file used for storing data. Defaults to ./steganodb.png.
• options: Optional. Additional options for the database.

table(tableName: string): SteganoDB

Creates and returns a new SteganoDB instance for a specified table.

• tableName: The name of the table to create.

get(key: string): any

Retrieves the value associated with the specified key.

• key: The key whose value should be retrieved. Supports nested keys using dot notation.

has(key: string): boolean

Checks if a value exists for the specified key.

• key: The key to check for existence. Supports nested keys using dot notation.

set(key: string, value: any): void

Sets the value for the specified key.

• key: The key to set the value for. Supports nested keys using dot notation. The key cannot be null or contain spaces.
• value: The value to set.

delete(key: string): void

Deletes the value associated with the specified key.

• key: The key whose value should be deleted. Supports nested keys using dot notation.

cache(key: string, value: any, time: number): void

Sets a temporary value for the specified key that will be automatically deleted after the specified time.

• key: The key to set the temporary value for. Supports nested keys using dot notation. The key cannot be null or contain spaces.
• value: The value to set.
• time: The time in milliseconds after which the value should be deleted. Must be a number.

add(key: string, count: number): void

Increments the value of the specified key by the specified count. If the key does not exist, it will be initialized to 0 before incrementing.

• count: The number to increment the value by. Must be a number.

sub(key: string, count: number): void

Decrements the value of the specified key by the specified count. If the key does not exist, it will be initialized to 0 before decrementing.

• key: The key whose value should be decremented. Supports nested keys using dot notation. The key cannot be null or contain spaces.
• count: The number to decrement the value by. Must be a number.

push(key: string, element: any): void

Pushes an element to an array associated with the specified key. If the key does not exist, an array will be created.

• key: The key whose array should be appended to. Supports nested keys using dot notation. The key cannot be null or contain spaces.
• element: The element to push into the array.

clear(): void

Clears all data in the database.

all(): Array<{ id: string, value: any }>
