NextJs Leaflet + MapBox

Leaflet is an open-source library that allows us to render a map on our website where we can show data, put marks wherever we want, and a lot more things, this is so useful and cool with Mapbox because we can custom our map and make it can fit with our website color pallet palette.

Instalation

First of all, we need to install React-Leaflet, for this we'll use this on our npm

npm i leaflet leaflet-defaulticon-compatibility leaflet-geosearch react-leaflet

after this is added to our package.json we can import this to our map component, I recommend you to create a separate component for the map, something like Map.jsx and add there all the necessary code and import all the dependence we need for our map

So, in our Map.jsx let's import the next things

import { MapContainer, TileLayer, Marker, Popup } from 'react-leaflet';
import 'leaflet/dist/leaflet.css';
import 'leaflet-defaulticon-compatibility/dist/leaflet-defaulticon-compatibility.css';
import 'leaflet-defaulticon-compatibility';

Components

MapContainer: this wrap and display our map, so we need to pass some props

center: we need to pass the latitude and longitude in an array something like [8.9880228180055, -79.52932768202]
zoom: we pass a number, more high number means more zoom
scrollWheelZoom: true or false for allowing zoom with the mouse scroll

TileLayer: this allows us to add our custom map and attribution if we want

Marker: this holds all the popup we wanna add to a point in the map

position: this is the place we wanna add the mark

Popup: We can add all the HTML labels or components around this, then display that in the popup.

Final Map's code

import { MapContainer, TileLayer, Marker, Popup } from 'react-leaflet';
import 'leaflet/dist/leaflet.css';
import 'leaflet-defaulticon-compatibility/dist/leaflet-defaulticon-compatibility.css';
import 'leaflet-defaulticon-compatibility';
import { chakra, Flex } from '@chakra-ui/react';

const MapFooter = () => {
  const place = [8.988022628180055, -79.52932561768202];
  return (
    <div>
      <MapContainer
        center={place}
        zoom={17}
        scrollWheelZoom={false}
        style={{ width: '100%', height: '350px' }}
      >
        <TileLayer

        />
        <Marker position={place}>
          <Popup className="mapBtn">
            <Flex flexDir={'column'} alignItems="center">
              <chakra.p fontWeight={'bold'} fontSize="lg">
                Anubis
              </chakra.p>
              <chakra.a
                target={'_blank'}
                href="https://goo.gl/maps/3bqJp4NzEiQU86ai6"
                bg={'primary.900'}
                textDecor={'none'}
                p="2"
                rounded={'base'}
                style={{ color: 'orange !important' }}
                _hover={{
                  bg: 'primary.400',
                }}
              >
                Google Maps
              </chakra.a>
            </Flex>
          </Popup>
        </Marker>
      </MapContainer>
    </div>
  );
};

export default MapFooter;

Fix NextJs problem with Leaflet

The leaflet is made without thinking about SSR so it works with the windows object is not defined when the SSR start preparing our components for render the website, this will make you have an error like windows is undefined for fix this we need to use something we can find in the nextjs documentation
then in the component we wanna add our map component, we have to import it with a dynamic function is made by nextjs
is something like this

const MapLealfet = dynamic(() => import('../MapFooter/MapFooter'), {
  ssr: false,
});

with this, your map should work fine now :)

Custom Map with MapBox

How maybe you realize in the URL of our TileLayer have a direction with names like YOUR_USER_NAME, YOUR_STYLE_TOKEN and YOUR_ACCESS_TOKEN this is because you need to add this information using your MapBox's account, so go to MapBox and create your account

When you access your account you should see something like this

then after that let's create a new style, click that button and you should see something now like this

here you can choose the style you prefer and after that you can even custom more that like change the street color, bus street color etc.

is something like this

now enter to your account that will show you a dashboard with tokens, I recommend you to create a Token per map you wanna use then it will work separately and can skip some future problems

so the final part is to come to our styles section and click on the share icon of the style we wanna use, which will show this

here we have
our username, our style token and you can use the access token we create for the map in our account section.
so add that information in the TileLayer URL --> url="https://api.mapbox.com/styles/v1/**YOUR_USER_NAME**/**YOUR_STYLE_TOKEN**/tiles/256/{z}/{x}/{y}@2x?access_token=**YOUR_ACCESS_TOKEN**"

Final

So here you should have a custom map cool can fit perfectly in your website design with the ability to add icons and the directions we need, and show different data we need, there is not limit for your creativity
