This article helps the user to render the map on the page using Leaflet. Using the leaflet, we can render the map into an HTML element and we can set the marker on the map. Leaflet works efficiently across all major desktop and mobile app platforms.

What is Leaflet

Sharp maps with zooming, Tile layers, WMS, Markers, Popups, Vector layers (polylines, polygons, circles, etc.), Image overlays and GeoJSON and feature layers that you supply. It handles different essential undertakings like changing data to map layer and mouse connections, and it's anything but difficult to stretch out with plugins. It will likewise function admirably crosswise over most sorts of gadgets. See Anatomy of a Web Map for a prologue to the most widely recognized sorts of web maps, which is the thing that Leaflet is useful for.

Provide any information for you! The leaflet is a system for appearing and interfacing with map data, however, it's dependent upon you to give that data, including a basemap. The leaflet is not GIS, in spite of the fact that it very well may be joined with devices like CartoDB for GIS-like capacities. On the off chance that you require to add up to an opportunity of form, communication, changes, and open street map projections.

How to Use Google Maps in Leaflet?

• Set up the project

  • Include Leaflet.js and CSS files in your HTML.

  • Create a basic HTML structure with a <div> element to hold the map.

• Initialize a Leaflet map

  • Create a div element with a specific ID for the map container.

  • Initialize the Leaflet map using L.map() and set the center coordinates and zoom level.

• Add Google Maps Layer

  • Use the Leaflet.GridLayer.GoogleMutant plugin or an alternative method to add Google Maps layers.

  • Add multiple Google base layers such as satellite, terrain, roadmap, and hybrid views.

• Switch Between Layers

  • Enable layer control using L.control.layers() to allow users to switch between different Google Maps base layers.

• Add Markers and Interactions

  • Place markers on the map using L.marker() with latitude and longitude coordinates.

  • Bind popups to markers for displaying information on click.

  • Use custom icons for markers by creating L.icon() instances.

  • Add interactive features such as popups, tooltips, and event listeners to enhance user experience.

Before Start!

You should have a text editor like Sublime Text or Notepad++.

Let's make a map!

The map above requires only a few things:

The html page

The Leaflet CSS styles

The Leaflet JavaScript library

<div>  element to hold the map

A height style specified for the map div.

A short script to create the map in that <div>

Downloading Leaflet

You can download Leaflet from

http://cdn.leafletjs.com/leaflet/v0.7.7/leaflet.css

http://cdn.leafletjs.com/leaflet/v0.7.7/leaflet.js

How about we center around the code in that <script> tag close to the end.

What did we do?

• Made a map variable

• Utilized L.map() to instantiate the map object.

• passing this object to the id of the div, where we need the map to render

• Use the setView() function to focus the initial map

• Use L.tileLayer() function to pass URL of map tile pictures. to make a base layer of map tilesFor example in this article, we're using google's basemap. Though, there are numerous alternatives out there. {z}/{x}/{y} is a format that Leaflet uses to discover tiles at the right zoom, x, and y facilitates. (See Anatomy of a Web Map). Similarly, we indicated a couple of alternatives:

Utilized addTo() method to add this tile layer to the map, we have just created.

Steps to use leaflet on your page:

Step 1:

First include css and js file in your page

<link rel=”stylesheet” type=”text/css” href=”leaflet/leaflet.css”/>

<script type='text/javascript' src=”leaflet/leaflet.js”></script>

Step 2:

Create a div element with an id

<div id=”myMap”></div>

Make sure the map container has a defined height eg.

# myMap { width:600px;height: 550px;}

Step 3:

Add script section on your page

<script>

window.onload=function(){

} <script>

Step 4:

Setting up the map

First initialize the map and set the geographical coordinates and a zoom level do this code in window.onload

var mymap = L.map('map').setView([51.505, -0.09], 13);

Step 5:

Add layer to the map

L.tileLayer('http://{s}.google.com/vt/lyrs=m&x={x}&y={y}&z={z}', {

maxZoom: 20,

subdomains: ['mt0', 'mt1', 'mt2', 'mt3']

}).addTo(mymap);

Output:

set marker on map:

For setting the marker, we will pass the geographical coordinates in to L.marker and add it to the map

var marker=L.marker([51.5, -0.09]).addTo(mymap);

Set popup on marker:

For setting the popup we will pass the message in to bindPopup and open the popup

marker.bindPopup('I am marker.')

marker.openPopup();

Output:

Set custom icon marker:

Make the icon

var customicon = L.icon({

iconUrl: 'customicon.png', //image file

iconSize: [38, 95], // size of the icon

});

Add this icon on the map​

var marker= L.marker([51.5, -0.09], {icon: customicon}).addTo(mymap)

marker.bindPopup('I am marker.')

marker.openPopup();

Output:

We can also set the marker as HTML content rather than an image icon. For this, We will create Div Icon and then add it to map

var markerOptions = {

icon: new L.DivIcon({

className: 'my-div-icon',

html: '<b class="icon" style="font-size: 16px;border:solid;padding:2px;border-width:

thin;border-bottom: 3px solid;border-right: 3px solid;color:white;background-color:red;border-

color:black">icon</b>'

})

};

I have used inline CSS, though an external CSS can also be used.

Now add the “markerOption” variable into marker

var marker= L.marker([51.5, -0.09], markerOptions).addTo(mymap)

marker.bindPopup(‘I am marker.')

marker.openPopup();

Output

we can also set marker popup as html content rather than string or text. For this add html into popup and you can also set width and height of this popup

var marker= L.marker([51.5, -0.09]).addTo(mymap)

marker.bindPopup("<div class='markerPopup' ><h2>London, UK<h/h2><h3>Wednesday,

2:00 PM</h3><h3>Mostly Cloudy</h3></div>", {

maxWidth : 560

});

marker.openPopup();

Output
