This repository contains a unified set of TypeScript-based Node.js packages for use across multiple projects. All packages are published to the GitHub Package Registry.

• Package Manager: Bun

• packages/biome-base: Base utilities and shared configuration
• packages/core: Core library functionality
• packages/langchainjs-patches: LangChain community patches and extensions
• packages/tsconfig-base-bun: Shared TypeScript config for Bun

• Strict TypeScript: All code uses strict settings (see tsconfig.json)
• Explicit Types: No any type, always use explicit types
• Immutable Patterns: Prefer readonly and const assertions
• Error Handling: Use Result/Either patterns or proper error types
• Dependency Injection: Use interfaces for loose coupling
• Single Responsibility: Each module has one reason to change

• Minimum 90% code coverage for new code
