Leaflet component for Dash

Project description

Dash Leaflet is a light wrapper around React-Leaflet. The syntax is similar to other Dash components, with naming conventions following the React-Leaflet API.

Getting started

The easiest way to get started is to install the latest version of Dash and Dash Leaflet via pip.

pip install dash==2.0.0
pip install dash-leaflet

Once the installation is completed, paste the following lines of code into a .py file and run it.

import dash
import dash_leaflet as dl

app = dash.Dash()
app.layout = dl.Map(dl.TileLayer(), style={'width': '1000px', 'height': '500px'})

if __name__ == '__main__':
    app.run_server()

If you visit http://127.0.0.1:8050/ in your browser, you should see a Leaflet map.

Documentation

The documentation has been moved to Heroku to enable an interactive example gallery.

NB: The 0.1.0 release contains a number breaking changes, most prominently merging of the SuperCluster and GeoJSON components into a new GeoJSON component powered by functional properties.
