react-neshan-map-openlayers

⚛️ A minimal React wrapper for OpenLayers 5+

Getting started

We have two components: NeshanMapLoader, NeshanMap.
Please note that to use NeshanMap component you must first load Openlayers library.

In the simple case you just need to add options prop to NeshanMap component under the NeshanMapLoader component.

import React, { useState } from "react";
import NeshanMap, {NeshanMapLoader} from "react-neshan-map-openlayers";

const SimpleMap = () => {
  const [ol, setOl] = useState();

  return (
    <NeshanMapLoader onLoad={setOl}>
      {ol && (
        <NeshanMap
          options={{
            key: "YOUR_API_KEY",
            view: new ol.View({
              center: ol.proj.fromLonLat([51.338076, 35.699756]),
              zoom: 13,
            }),
          }}
        />
      )}
    </NeshanMapLoader>
  );
};
export default SimpleMap;

Installation

npm:

npm install react-neshan-map-openlayers

Features

Neshan Maps API Loads on Demand

There is no need to place a <script src= tag at top of page. The Neshan Maps API loads upon the first usage of the NeshanMap component.

Use Openlayers Maps API

You can access to map objects by using onInit.

...
<NeshanMapLoader onLoad={setOl}>
  {ol && (
    <NeshanMap
      options={{
        key: 'YOUR_API_KEY',
        maptype: 'dreamy',
        poi: true,
        traffic: false,
        view: new ol.View({
          center: ol.proj.fromLonLat([51.338076, 35.699756]),
          zoom: 14
        })
      }}

      onInit={(myMap) => {
        var layer = new ol.layer.Vector({
          source: new ol.source.Vector({
            features: [
              new ol.Feature({
                geometry: new ol.geom.Point(
                  ol.proj.fromLonLat([51.338076, 35.699756])
                )
              })
            ]
          }),
          style: new ol.style.Style({
            image: new ol.style.Icon({
              color: '#BADA55',
              crossOrigin: 'anonymous',
              src:
                'https://openlayers.org/en/latest/examples/data/square.svg'
            })
          })
        })
        myMap.addLayer(layer)
      }}

    />
  )}
</NeshanMapLoader>
