@eac-arch/infrastructure-config

Angular infrastructure library for runtime configuration loading and access.

Purpose

@eac-arch/infrastructure-config centralizes runtime configuration access through a typed service and Angular providers. It supports:

• preloaded configuration via DI
• path-based reads (a.b.c) with safe and strict variants
• browser session persistence for config reuse
• optional startup prefetch with timeout handling

Main Capabilities

• ConfigService : Stores config in an Angular signal and exposes read methods.
• provideConfig() : Registers ConfigService using PLATFORM_ID and optional preloaded config.
• provideConfigTesting() : Test-friendly provider with deterministic preloaded values.
• prefetchConfig(url, timeoutMs) : Fetches runtime JSON config in browser environments.
• getByPath() / requireByPath() : Nested path utilities for dynamic config access.

Public API

export type { AppConfig };
export { ConfigService, APP_CONFIG_TOKEN, providePreloadedConfig };
export { provideConfig, provideConfigTesting };
export { prefetchConfig };
export { getByPath, requireByPath };

Usage

import { ApplicationConfig } from '@angular/core';
import { provideConfig } from '@eac-arch/infrastructure-config';

export const appConfig: ApplicationConfig = {
  providers: [
    ...provideConfig(),
  ],
};

Read configuration values:

const apiBase = configService.require<string>('API.BASE_URL');
const optionalTimeout = configService.get<number>('HTTP.TIMEOUT_MS');

Dependencies

• tslib
