Usage

This package is designed to simplify the development of applications using NiceGUI by enabling file-based routing and consistent theming. Below is a demonstration of how to set up a simple application using nicegui-router.

Example Project Structure

my_nicegui_app/
├── main.py
└── routes
    ├── home.py
    └── about.py
    └── counter.py

Example Code

main.py

from nicegui_router import Server
from pathlib import Path

# Initialize the router with the directory containing your route files
server = Server(
    title='Example Server', 
    routes_dir=Path(__file__).parent / "routes"
)

# Get the Fastapi app instance (for advanced use cases)
app = server.app

# Start the server if the script is run directly
if __name__ == '__main__':
    server.listen(port=8080)

routes/index.py

from nicegui_router import page, ui

@page('/')
def home():
    ui.markdown("Welcome to the Home Page!")

routes/about.py

from nicegui_router import page, ui, theme

customTheme = theme(
    {
        'primary': '#FF5733', # orange
        'secondary': '#33FF57', # green
        'accent': '#3357FF'
    }, font="Lato")

@page(theme=customTheme)
def about():
    ui.markdown("About Us Page themed with custom colors.")

routes/counter.py

from nicegui_router import page, ui, theme, component, use_state

customTheme = theme(
    {
        'primary': '#FF5733', # orange
        'secondary': '#33FF57', # green
        'accent': '#3357FF'
    }, font="Lato")

@page(theme=customTheme)
def counter():
    # custom component with state reactivity support
    @component
    def customCounter():
        count, setCount = use_state(0)
        return ui.button(f"Count: {count}").on("click", lambda: setCount(count + 1))

    with ui.header():
        title = ui.label("Example 2")
        ui.space()
        customCounter()
    ui.markdown("Custom component with state reactivity.")

Starting the Server

To start the server, simply run the following command in your terminal from the project's root directory:
