Features

• Simple API: GoodDB provides a simple and intuitive API for common database operations, making it easy to use and understand.
• Multiple Drivers: Choose from a variety of drivers to store data in memory, files, or databases such as SQLite, MongoDB, and more.
• Async/Await Support: GoodDB supports async/await for seamless integration with modern JavaScript and TypeScript applications.
• Flexible Configuration: Customize the database configuration to suit your needs, including table/collection names, nested key handling, and more.
• Type Safety: GoodDB is written in TypeScript and provides type definitions for a seamless development experience.
• Fast and Lightweight: GoodDB is fast and lightweight, making it ideal for small to medium-sized applications.
• Caching: GoodDB supports caching to improve performance and reduce the number of database queries.

Installation

You can install GoodDB via npm:

1npm install good.db

Configuration

You can customize the database configuration by passing options to the driver:

1const db = new GoodDB(new JSONDriver({ path: './database.json' }), {
2  table: 'data',
3  nested: '.',
4  nestedIsEnabled: true,
5  cache: {
6    isEnabled: true,
7    capacity: 1024
8  }
9});

• table (string): The name of the table/collection in the database.

• nested (string): The character used to separate nested keys.

• nestedIsEnabled (boolean): Whether to enable nested key handling.

• cache

  • isEnabled (boolean): Whether to enable caching.
  • capacity (number): The maximum number of entries to cache.

Drivers

GoodDB supports the following drivers:

7    to: new JSONDriver({
8        path: './client/database.json'
9    }),
10    table: 'all_tables',
11});
12
13convertor.convert().then(console.log).catch(console.error);
