Introduction

JWeb is a Java web framework for building complete web applications entirely in Java. No direct HTML, CSS, or JavaScript writing - just Java.

Why JWeb?

• HTML DSL - Java methods that generate HTML with compile-time safety
• CSS DSL - Java fluent methods that generate CSS with full IDE support
• No npm/webpack - Just Maven, like any Java project
• Spring Boot powered - Production-ready from day one
• Reactive state - Built-in state management for dynamic UIs

Hello World

public class HelloPage implements Template {
    public Element render() {
        return h1("Hello, World!");
    }
}

With Styling

public Element render() {
    return div(attrs().style()
            .padding(rem(2))
            .backgroundColor(hex("#f5f5f5")).done(),
        h1("Welcome to JWeb"),
        p("Build web apps in pure Java")
    );
}

How It Works

JWeb renders Java objects to HTML on the server. The HTML DSL provides methods that generate markup. The CSS DSL uses fluent builders for styles.
