React Leaflet Polytools Component

DRAFT ONLY --- PRE PRE ALPHA

A component (or suite of High Order Components ??) to facilitate easy and fast tools for drawing and editing polygons on maps.

Features

• configurable tile server (or agnostic if HOC)
• fast and easy polygon draw and edit - single
• fast and easy polygon draw and edit - multiple
• events: onDraw, onEdit, onDelete (polygons)
• helpers: canCreatePolygon

Plan Data Flow

Page -> HOC to maintain state (redux) -> ReactLeafletPolytools -> Leaflet/Draw

Polygon data goes back up to HOC/state (outside of ReactLeafletPolytools)

Then comes back down via props, triggering a re-draw of polygons

About

This is a controlled component, no internal state

It can optionally can be extended / composed with HOC to extend controls.

It does support basic configuration out-of-the-box, but most of the "work" is to be handled by helper functions, pass in props. (again, the HOC can make this painless)

Intall

npm i --save react-leaflet-polytools

or

yarn i react-leaflet-polytools

Usage

import ReactLeafletPolytools from 'react-leaflet-polytools';

export default MyPage = ({ mapData, ...props }) => (
  <div>
    <h1>Here is an editable Polygon Map</h1>
    <ReactLeafletPolytools
      {...mapData}
      canAddPolygon={mapData => true}
      canEditPolygon={mapData => true}
      canDeletePolygon={mapData => true}
      onChange={mapData => console.log('map data changed', mapData)}
    />
  </div>
);

Props

• canAddPolygon function
• default (mapData) => true;
• canEditPolygon function
• default (mapData) => true;
• canDeletePolygon function
