@joker.server/core

@joker.server/core is the core server-side framework of the Joker ecosystem. Built upon the KOA framework, it's designed to empower developers with an efficient and streamlined experience for building server-side applications. By inheriting KOA's lightweight and flexible nature, it simplifies common server-side development workflows through thoughtful encapsulation and extensions.

Key Features

• KOA-Powered Foundation: Fully compatible with KOA's middleware architecture and ecosystem. Seamlessly integrate existing KOA middleware (e.g., koa-router, koa-bodyparser) to minimize learning curve and migration efforts.
• Simplified Configuration: Offers straightforward initialization and sensible defaults, reducing boilerplate code and letting developers focus on business logic.
• Batteries-Included: Bundles essential features like routing, request handling, and error trapping, eliminating the need to stitch together multiple libraries.
• Highly Extensible: Supports custom middleware and plugins, adapting flexibly to diverse project requirements.
• Integrated Caching: Manages multiple caching strategies (in-memory, Redis, etc.) to boost response times and reduce server load.
• Request Validation: Automatically checks incoming parameters against predefined rules (types, ranges, required fields), minimizing manual validation code.
• JWT Authentication: Implements JSON Web Token authentication with token generation, verification, and role-based access control for secure API endpoints.

Quick Start

Installation

Install via npm or yarn:

npm install @joker.server/core
# or
pnpm add @joker.server/core

Basic Usage

Initialize the server, register routes, and start serving requests in just a few lines of code.

Relationship with KOA

@joker.server/core is built on top of KOA, inheriting its core app instance. This means:

• All native KOA methods (e.g., use, listen) work out-of-the-box.
• KOA ecosystem middleware can be directly imported and used, ensuring full compatibility with existing KOA projects.
• Leverages KOA's async/await-based asynchronous flow control for cleaner, more readable code without callback hell.
