@ediflow/infrastructure-shared

Shared infrastructure utilities for EDIFlow packages (EDIFACT, X12)

📦 What's This Package?

This package provides shared infrastructure components used by multiple EDIFlow format packages (EDIFACT, X12).

import { 
  LRUCacheManager,
  FileBasedMessageStructureRepository,
  CachedDefinitionLoader
} from '@ediflow/infrastructure-shared';

// EDIFACT Package uses these
// X12 Package uses these
// No code duplication!

🎯 Why a Separate Package?

DRY Principle: Don't Repeat Yourself

• EDIFACT and X12 both need cache, repositories, loaders
• Instead of duplicating code, share it!
• Bug fix in one place → benefits all packages

📋 What's Included?

Cache Implementations

• LRUCacheManager - LRU cache for fast lookups

Repositories

• FileBasedMessageStructureRepository - Loads definitions from JSON files
• InMemoryMessageStructureRepository - For testing

Loaders

• CachedDefinitionLoader - Loads definitions with caching

🚀 Usage

// EDIFACT Package
import { LRUCacheManager, FileBasedMessageStructureRepository, CachedDefinitionLoader } from '@ediflow/infrastructure-shared';

const repo = new FileBasedMessageStructureRepository('./data/edifact');
const loader = new CachedDefinitionLoader(repoManager, 100); // LRU cache size 100
