🚦 Return Values

The component returns detailed interaction data:

{
    "swipedCards": [
        {"index": 0, "action": "right"},   # Liked first card
        {"index": 1, "action": "left"}     # Passed second card
    ],
    "lastAction": {
        "cardIndex": 1, 
        "action": "left"
    },
    "totalSwiped": 2,      # Total cards swiped
    "remainingCards": 8    # Cards left in stack
}

🎨 Theme Integration

• Buttons and default table highlights adapt automatically to the active Streamlit theme.
• No flags required: the component derives colors from your app theme (or defaults if none is set).
• Adjust table readability with table_font_size (px); optionally trim rendered data with table_max_rows and table_max_columns for smaller layouts.

Custom Colors

You can override component colors via the colors parameter. Provide valid CSS colors. Keys can be top-level or nested under buttons.

Example (customize button backgrounds and text):

result = streamlit_swipecards(
    cards=cards,
    colors={
        # Buttons (top-level or nested under "buttons")
        "like_bg": "#22c55e",   # green
        "like_fg": "#ffffff",
        "pass_bg": "#ef4444",   # red
        "pass_fg": "#ffffff",
        "back_bg": "#374151",   # gray
        "back_fg": "#ffffff",
        "btn_border": "#ffffff",
        # Base colors (optional)
        "card_bg": "#1f2937",
        "background_color": "#0b0f16",
        "secondary_background_color": "#111827",
        "text_color": "#e5e7eb",
    },
)

Nested form also works:

colors={
    "buttons": {
        "like": {"bg": "#22c55e", "fg": "#fff"},
        "pass": {"bg": "#ef4444", "fg": "#fff"},
        "back": {"bg": "#374151", "fg": "#fff"},
        "border": "#fff",
    }
}
