React Leaflet Version 3, the one that has been rewritten to use hooks, is used for this course. It is based on two widely used open-source Javascript libraries – React and Leaflet. Let’s set the scene with a brief introduction:

React – is the most popular JavaScript library you can learn to build modern, reactive user interfaces for the web. It has become so popular because it can be implemented on an individual component basis rather than having to update an entire web-application. This is a big advantage when it comes to modernizing entire web applications. Furthermore, React.js is built with performance as its core objective. Put simply, it stores Javascript objects in memory (without the heavy rendering step!) in a “Virtual DOM”. When the Virtual DOM is updated, a diffing algorithm identifies the most efficient way to update (i.e. re-render) the components to the actual visible DOM. React is developed and maintained by Meta (Facebook) and is here to stay.

Leaflet – due to its simplicity, being open-source and designed with the specific intention of being easy to use, it is a very popular Javascript library for building mobile friendly interactive maps. Leaflet is trusted by Github, Facebook, Esty and Pintereset among others, and again, it is also here to stay!

As the name may indicate, React Leaflet is an integration these two well established libraries by providing bindings between them. It leverages the power of the Leaflet library, abstracting Leaflet layers as React components. By doing so:

Leaflet can be integrated seamlessly into React applications;

React third party Javascript libraries can be utilized within Leaflet components (see course contents below);

Similar to Leaflet, this course is ‘built around simplicity’!!! We won’t get bogged down with configuring web servers, or middlewares. Instead the course aims to provide exposure into all facets of the React Leaflet library while also teaching you how to access the necessary resources to deepen your knowledge and develop your own React Leaflet web applications. The completed application from each code along video is provided as a downloadable resource. This makes it possible for you to jump in just at the place you’d like to and also possible to get a working version of the code if you get stuck.

The course starts with introducing concepts for beginners and gradually progresses to some advanced topics. Each section will build on the last and by the end you’ll have a functional React Leaflet web application.
