Leaflet.js: Build Realtime Maps, GPS Trackers & Location App

Build real, interactive maps for the web — not just a pin on a page.

Leaflet.js is the most widely used open-source mapping library in the world. It powers the map layer of countless GPS tracking platforms, fleet management dashboards, logistics applications, and location-based services. It is lightweight, flexible, and far more capable than most developers realize when they first encounter it.

This course takes you from zero to confident — covering the full range of what Leaflet.js can do, with practical examples at every step.

What you will learn:

• How to set up Leaflet.js and integrate it into a web project from scratch

• How to work with map tiles, layers, and different map providers

• How to add and customize markers, popups, and tooltips

• How to draw shapes, polygons, and geofence zones on a map

• How to handle real-time position updates and animate movement on a map

• How to build interactive controls and respond to user map events

• How to work with GeoJSON data and display it on a map

• How to optimize map performance for larger datasets

Who this course is for:

• Web developers who want to add mapping and location features to their applications

• Developers building GPS tracking, fleet management, or logistics platforms

• Frontend developers who need to display location data in a clear, interactive way

• Anyone who has tried to use Leaflet.js and found the official documentation lacking in practical guidance

Why Leaflet.js:

It is free, open source, and runs entirely in the browser without depending on paid APIs. For developers building location-based applications — especially GPS tracking systems — it is the most practical choice for the frontend map layer.

Prerequisites: Basic HTML, CSS, and JavaScript knowledge. No mapping or GIS experience required.
