@denis_bruns/core

A TypeScript library providing core interfaces and types for building modular, testable web applications.

Overview

@denis_bruns/core contains interfaces and types that serve as foundational building blocks for multiple libraries in your ecosystem. Previously part of a larger monorepo, it’s now separated into smaller, more focused packages. This core library helps keep your codebase:

• Modular – By defining reusable contracts and abstractions.
• Testable – Through clearly separated concerns and consistent interfaces.
• Extensible – Encouraging a clean architecture approach with shared definitions.

Installation

Using npm:

npm install @denis_bruns/core

Or yarn:

yarn add @denis_bruns/core

Key Features

1. Shared Contracts – Common interfaces for HTTP clients, data filters, pagination, and more.
2. Clean Architecture Support – Define entity gateways, repositories, and domain models with reusable types.
3. Type-Safe – Written in TypeScript to provide robust type checking and IDE autocompletion.
