Cord-DB

A simple Node.js class for managing JSON data storage. It allows saving, loading, updating, and deleting JSON data.

Installation

To use this package, make sure you have Node.js installed, then run:

npm install cord-db

Usage

1. Importing the Package

const DataManager = require('cord-db');

2. Creating an Instance

You can specify the file path where your JSON data will be stored (default is ./data.json).

const db = new DataManager('./path-to-your-data-file.json');

3. Saving Data

To save data (an object) to the JSON file:

const data = { name: "John", age: 30 };
db.save(data);

4. Loading Data

To load the data from the JSON file:

const loadedData = db.load();
console.log(loadedData);

If the file doesn't exist or is empty, it will return null.

5. Updating a User's Key

You can update a specific user's data by specifying the userId, key, and value.

db.updateUserKey(userId, 'coins', amount);

This will update the coins field for the user with ID 1234567890 with new amount.

6. Retrieving a User's Key

To get the value of a specific key for a user:

const userCoins = db.getUserKey('user123', 'coins');
console.log(userCoins);

const coins = db.getUserKey(userId, 'coins') ||  0;
console.log(coins);

If the key doesn't exist for the user, it will return null.

7. Deleting the Data File

To delete the entire data file:

db.delete();

This will remove the file where your data is stored.
