Dracula dark/light theme for Plotly Dash applications

Dracula for Dash

A dark theme for Plotly Dash — pip-installable Python package that gives any Dash application the full Dracula colour experience, including a light-mode toggle and always-light PDF export.

Dark mode	Light mode

Install

All instructions can be found at INSTALL.md.

Features

• Dark mode — full Dracula palette applied via CSS variables and a custom Plotly template
• Light mode toggle — single button switches the entire dashboard; all Plotly graphs re-colour automatically via a clientside callback
• PDF export — fig_to_print_image() always produces print-ready figures on a white background, regardless of the current dashboard theme
• Official palette — all 11 Dracula colours exposed as named Python constants (BACKGROUND, CYAN, PURPLE, …)

Quick start

import dash
import dash_bootstrap_components as dbc
import dash_dracula as dr

# 1. Create the app with Bootstrap DARKLY as base
app = dash.Dash(__name__, external_stylesheets=[dbc.themes.DARKLY])

# 2. Wire the Dracula theme (copies CSS, registers clientside toggle)
theme_store = dr.apply_theme(app)          # returns dcc.Store for the layout

# 3. Use Dracula colours and template in your figures
fig = go.Figure(layout=dict(template="dracula"))
fig.add_scatter(y=[1, 2, 3], line_color=dr.CYAN)

# 4. Export a figure to a print-ready ReportLab Image (always light)
from dash_dracula.pdf import fig_to_print_image
img = fig_to_print_image(fig, w_mm=170, h_mm=100)

See sample/app.py for a complete minimal example.
