@biorate/config-loader

Config loader abstraction — abstract base class for all config loaders in the @biorate DI ecosystem.

Features

• DI-ready — decorated with @injectable(), injects IConfig.
• Template Method pattern — abstract initialize() must be implemented by subclasses.
• Lifecycle integration — @init() decorator from @biorate/inversion for automatic startup.

Installation

pnpm add @biorate/config-loader

Requires @biorate/config, @biorate/errors, @biorate/inversion.

Module reference

ConfigLoader — Abstract base

import { ConfigLoader } from '@biorate/config-loader';

| Member | Visibility | Type / Signature | Description | |--------------|---------------|------------------------------------------|-------------------------------| | config | protected readonly | IConfig | Injected config service. | | initialize | protected abstract | (): Promise<void> \| void | Load config into this.config. |

Usage pattern

import { injectable, init } from '@biorate/inversion';
import { ConfigLoader } from '@biorate/config-loader';

@injectable()
class EnvLoader extends ConfigLoader {
  @init()
  protected initialize() {
    this.config.merge({ env: process.env.NODE_ENV || 'development' });
  }
}

Architecture

ConfigLoader (abstract, @injectable)
│
├── @inject(Types.Config) config: IConfig    Injected on construction
│
└── @init() initialize() [abstract]          Called by Core.$run()
    │
    └── subclass implements                  Reads/parses → config.merge()
