A compiler-driven JavaScript framework for building high-performance user interfaces.

**[📑 Documentation](https://rpsffx.github.io/zess/)**



## 🔍 What is Zess?

Zess (pronounced /zɛs/) is a compiler-based JavaScript framework for building user interfaces on top of standard HTML, CSS, and JavaScript. Unlike traditional runtime-focused frameworks, Zess shifts the majority of its work to the compile stage. Through static analysis and compile-time optimizations, it transforms declarative components into lean, efficient imperative code. This results in reduced runtime overhead, faster initial page loads, and a user experience that approaches native-level performance.

## ✨ Features

- **⚡ High Performance**: Deeply optimized compiler output, combined with an efficient reactive system using Signals, delivers native-like smoothness.

- **🔒 Full Type Safety**: Built-in TypeScript support ensures end-to-end type checking across development and build, improving code reliability.

- **🛠️ Fast Development**: Powered by Vite for millisecond-level hot updates and efficient bundling, boosting development productivity.

- **📚 Easy to Learn**: Familiar API design inspired by mainstream frameworks lowers the learning curve and speeds up proficiency.

## 🎯 Getting Started

Create a new Zess project via CLI where `my-app` is your project directory:

```bash

npx -p @zessjs/cli init my-app

```

### Start Development Server

Navigate to the project directory and start the development server:

```bash

cd my-app

npm run dev

```

### Build for Production
