How It Works

• Build your UI using Python classes and components (like Text, Button, Container, Page, etc).
• Preview instantly with hot-reload using app.rTimeCompile().
• Export your app to static web files with a single CLI command.
• Use multipage, layouts, scripts, and more—see docs for advanced features.
• For mor information visit the Documentation

Quick Example: Your First App

Note: this is an single page example but you can build multipage apps with Page component see the Components Documentation to know more.

from dars.all import *

app = App()

# Crear aplicación con sintaxis nueva (v1.0.3)
container = Container(
    Text(
        "Hola Dars",
        style={'font-size': '32px', 'color': '#333'}
    ),
    Button(
        "Hacer clic",
        style={'background-color': '#007bff', 'color': 'white'}
    ),
    style={
        'display': 'flex',
        'flex-direction': 'column',
        'align-items': 'center',
        'padding': '40px'
    }
)

# Script para interactividad
script = InlineScript("""
document.addEventListener('DOMContentLoaded', function() {
    const boton = document.querySelector('button');
    boton.addEventListener('click', function() {
        alert('Hola desde Dars.');
    });
});
""")

# Ensamblar aplicación
app.set_root(container)
app.add_script(script)

if __name__ == "__main__":
    app.rTimeCompile()  # Live preview at http://localhost:8000

Local Execution and Live Preview

To test your app locally before exporting, use the hot-reload preview from any Python file that defines your app:

if __name__ == "__main__":
    app.rTimeCompile()

Then run your file directly:

python my_app.py

This will start a local server at http://localhost:8000 so you can view your app in the browser—no manual export needed. You can change the port with:

python my_app.py --port 8088

---

You can also use the CLI preview command on an exported app:

dars preview ./my_exported_app

This will start a local server at http://localhost:8000 to view your exported app in the browser.
