HazelJS Beta: Why We Built It — Design, Purpose & Benefits

A different kind of framework announcement. Why we built HazelJS — AI-native, modular, TypeScript-first. Includes npm package links, design principles, and real use cases for @hazeljs/core, @hazeljs/ai, @hazeljs/agent, @hazeljs/rag, and more.

Introduction

HazelJS is redefining the JavaScript runtime landscape with a focus on speed, security, and developer experience. In this article, we dive deep into the core innovations that set HazelJS apart and how you can leverage them in your next project.

Why HazelJS?

Performance: Advanced JIT compilation and memory management deliver lightning-fast execution.
Security: Built-in protections against common vulnerabilities, so you can ship with confidence.
Developer Experience: TypeScript-first, modern APIs, and seamless tooling integration.

Getting Started Example

Here's how easy it is to spin up a HazelJS server:


import { HazelModule, HazelApp, Controller, Get } from '@hazeljs/core';

@Controller({ path: '/hello' })
class HelloController {
  @Get()
  hello() {
    return { message: 'Hello, World!' };
  }
}

@HazelModule({
  controllers: [HelloController],
})
class AppModule {}

const app = new HazelApp(AppModule);
app.listen(3000);

Key Features

Hot Reloading: Iterate faster with instant feedback.
AI-First Design: Native support for LLMs and generative AI workflows.
Zero-Config Deployments: Deploy globally with a single command.
