DatabaseFacade

DatabaseFacade is a simple and unified interface for interacting with different types of databases. It currently supports MySQL and PostgreSQL.

Installation

To use DatabaseFacade, you need to have the required database drivers installed. You can install them using npm:

npm install mysql2 postgres

Usage

Here is a basic example of how to use DatabaseFacade in your application:

import { DatabaseFacade, DatabaseConfig } from './src/index';

// Define your database configuration
const config: DatabaseConfig = {
    type: 'mysql', // or 'postgres'
    host: 'localhost',
    user: 'your-username',
    password: 'your-password',
    database: 'your-database',
    port: 3306 // or the port your database is running on
};

// Initialize the DatabaseFacade
DatabaseFacade.initialize(config);

// Example of calling a stored procedure
async function callMyProcedure() {
    try {
        const result = await DatabaseFacade.callProcedure('my_procedure_name', [param1, param2]);
        console.log('Procedure result:', result);
    } catch (error) {
        console.error('Error calling procedure:', error);
    }
}

// Close the database connection when done
async function closeConnection() {
    try {
        await DatabaseFacade.close();
        console.log('Database connection closed.');
    } catch (error) {
        console.error('Error closing connection:', error);
    }
}

// Call the procedure and close the connection
callMyProcedure().then(closeConnection);

API

DatabaseFacade.initialize(config: DatabaseConfig)

Initializes the database connection with the provided configuration.

DatabaseFacade.callProcedure(name: string, params: any[] = [], isFunction = false)

Calls a stored procedure or function with the given name and parameters.

DatabaseFacade.close()

Closes the database connection.

Configuration

The DatabaseConfig interface defines the configuration options for the database connection:

export interface DatabaseConfig {
    type: 'postgres' | 'mysql';
    host: string;
    user: string;
    password: string;
    database?: string;
    port?: number;
}
