How to display the map scale in leaflet.js

javascript, leaflet, openstreetmap

Solution

You can take use of `L.control.scale()`:

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

L.tileLayer('https://tile.openstreetmap.org/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);

L.control.scale().addTo(map);

<link rel="stylesheet" href="https://unpkg.com/leaflet@1.9.3/dist/leaflet.css" integrity="sha256-kLaT2GOSpHechhsozzB+flnD+zUyjE2LlfWPgU04xyI=" crossorigin="" />
<script src="https://unpkg.com/leaflet@1.9.3/dist/leaflet.js" integrity="sha256-WBkoXOwTeyKclOHuWtc+i2uENFpDZ9YPdf5Hf+D7ewM=" crossorigin=""></script>

<div id="map" style="width: 100%; height: 150px;"></div>

Problem

I wonder how to display the scale map in leafleat.js. That is: I want this instead of this (taken to leaflet tutorial). See the left corner of the picture.
