Configuration Manager

A utility that manages application configuration by merging multiple configuration sources with nested settings.

Capabilities

Configuration Merging

• Given base config { db: { host: 'localhost', port: 3306 }, server: { port: 8080 } } and env config { db: { host: 'prod-db' } }, the merged result is { db: { host: 'prod-db', port: 3306 }, server: { port: 8080 } } @test
• Given three configs: base { db: { host: 'localhost', port: 3306, timeout: 5000 } }, env { db: { host: 'prod-db', pool: 10 } }, and user { db: { timeout: 10000 } }, the result is { db: { host: 'prod-db', port: 3306, timeout: 10000, pool: 10 } } @test
• Merging deeply nested configs with base { api: { endpoints: { users: '/api/users', posts: '/api/posts' }, retry: { attempts: 3 } } } and override { api: { endpoints: { comments: '/api/comments' }, retry: { delay: 1000 } } } produces { api: { endpoints: { users: '/api/users', posts: '/api/posts', comments: '/api/comments' }, retry: { attempts: 3, delay: 1000 } } } @test

 * Merges multiple configuration objects deeply, with later configs taking precedence.

 * @param {Object} baseConfig - The base configuration with default values
 * @param {Object} envConfig - Environment-specific configuration
 * @param {Object} userConfig - User-provided overrides
 * @returns {Object} The merged configuration object
