Installation

To install the st.db package and its associated database drivers, follow these steps:

  1. Install the main st.db package:
npm install st.db

  1. Depending on the specific database drivers you intend to use, you will need to install the corresponding packages. Here are the drivers and their associated packages:

    • JSON and Cache: The JSONDriver and CacheDriver does not require any additional package installation.

    • better-sqlite3 (SQLite):

      npm install better-sqlite3

    • mongodb (MongoDB):

      npm install mongodb

    • pg (PostgreSQL):

      npm install pg

    • firebase (Firebase):

      npm install firebase

    • mysql2 (MySQL):

      npm install mysql2

    • yaml (YAML):

      npm install yaml

    Note: These packages are marked as optional, meaning you only need to install the ones that correspond to the specific database drivers you plan to use. If you're not using a particular driver, you can skip installing its associated package.

  2. Once you have installed the main st.db package and the necessary database driver packages, you're ready to start using st.db in your project!

Getting Started

To begin using st.db in your project, you can import the necessary database drivers and start interacting with your databases using the key-value interface. For detailed usage instructions and examples, refer to the documentation or examples provided for each individual driver.

Usage

Using Node.js require()

const { Database } = require('st.db');

TypeScript/ES Module support

import { Database } from 'st.db';

Deno support

import { Database } from 'npm:st.db';

Configuring Database Behavior Using DatabaseOptions

The DatabaseOptions object allows you to customize the behavior of the database when initializing it. Here's a detailed explanation of the available options:

  • encryptionOptions: This property accepts an object that defines additional options for encryption. These options can be used to fine-tune encryption behavior based on your security requirements.

  • autoDecrypt (optional): When set to true, this property enables automatic decryption of encrypted data as it's retrieved from the database.

  • encryption: This property accepts an object that provides information for data encryption. It includes the following properties:

    • password: The password used for encryption and decryption.
    • digest (optional): A cryptographic digest algorithm used to derive the encryption key from the provided password. If not specified, the default is SHA-256.

  • driver: By setting this property, you can specify the desired database driver from the Drivers type mentioned earlier. Choose the appropriate driver that matches your intended database technology.

Example Configuration

Here's an example of how you might configure the st.db package using the DatabaseOptions object:

Using JSONDriver

The JSONDriver allows you to store data in a local JSON file. Here's how you can use it:

import { Database, JSONDriver } from "st.db";

const options = {
  driver: new JSONDriver("data.json"), // Specify the JSONDriver and the JSON file name
};

const db = new Database(options);

Using YAMLDriver

The JSONDriver allows you to store data in a local YAML file. Here's how you can use it:

import { Database, YAMLDriver } from "st.db";

const options = {
  driver: new YAMLDriver("data.yaml"), // Specify the YAMLDriver and the JSON file name
};

const db = new Database(options);

Using XMLDriver

The XMLDriver allows you to store data in a local XML file. Here's how you can use it:

import { Database, XMLDriver } from "st.db";

const options = {
  driver: new XMLDriver("data.xml"), // Specify the XMLDriver and the JSON file name
};

const db = new Database(options);

Using MySQLDriver

The MySQLDriver connects to MySQL databases and provides data management features. Here's how to set it up:

import { Database, MySQLDriver } from "st.db";
const tableName = "my_table"; // Optional: specify the table name

const mysqlConfig = {
  host: "localhost",
  user: "username",
  password: "password",
  database: "my_database",
};

const options = {
  driver: new MySQLDriver(mysqlConfig,tableName), // Specify the MySQLDriver and the configuration
};

const db = new Database(options);

Using MongoDriver

The MongoDriver enables interaction with MongoDB databases. Here's how to use it:

import { Database, MongoDriver } from "st.db";

const mongoUrl = "mongodb://localhost:27017";
const dbName = "my_database";
const collectionName = "my_collection";

const options = {
  driver: new MongoDriver(mongoUrl, dbName, collectionName), // Specify the MongoDriver and the connection details
};

const db = new Database(options);

Using FirebaseDriver

The FirebaseDriver enables interaction with Firestore databases. Here's how to use it:

import { Database, FirebaseDriver } from "st.db";

// Replace these values with your actual Firebase configuration
const firebaseConfig = {
  apiKey: "your-api-key",
  authDomain: "your-auth-domain",
  projectId: "your-project-id",
  storageBucket: "your-storage-bucket",
  messagingSenderId: "your-messaging-sender-id",
  appId: "your-app-id",
};

const collectionName = "my_collection"; // Optional: specify the collection name

const options = {
  driver: new FirebaseDriver(firebaseConfig, collectionName), // Specify the FirebaseDriver and the configuration
};

const db = new Database(options);

Using CacheDriver

The CacheDriver provides an in-memory caching mechanism. Here's how to utilize it:

import { Database, CacheDriver } from "st.db";

const options = {
  driver: new CacheDriver(), // Specify the CacheDriver
};

const db = new Database(options);

Using PostgresDriver

The PostgresDriver enables interaction with PostgreSQL databases. Here's how to use it:

import { Database, PostgresDriver } from "st.db";
const tableName = "my_table"; // Optional: specify the table name
const postgresConfig = {
  user: "username",
  password: "password",
  host: "localhost",
  database: "my_database",
};

const options = {
  driver: new PostgresDriver(postgresConfig, tableName), // Specify the PostgresDriver and the configuration
};

const db = new Database(options);

Using SQLDriver

The SQLDriver provides an interface for general SQL databases. Here's how you can use it:

import { Database, SQLDriver } from "st.db";
const tableName = "my_table"; // Optional: specify the table name
const options = {
  driver: new SQLDriver("data.sqlite", tableName), // Specify the SQLDriver and the SQLite database file name
};

const db = new Database(options);

await db.subtract("balance", 50);

The Table class extends the functionality of the Database class to provide additional features for managing data in a specific table.

import { Table } from "st.db";

// Create a new table instance
const table = new Table("users", db);

// Set data in the table
await table.set("user1", { name: "Alice", age: 30 });

// Get data from the table
const userData = await table.get("user1");
console.log("User data:", userData);

// Check if a key exists in the table
const userExists = await table.has("user1");
console.log("User exists:", userExists);

// Retrieve all data from the table
const allData = await table.all();
console.log("All data:", allData);

// Clear all data from the table
await table.clear();

/* All methods of the Database class are available to the Table class */
