Now you should see your markers cluster together beautifully and those clusters dynamically update in size as you zoom the map in and out.

You will notice there is some custom code in there for popups as well - don’t fear that is coming up next! Now create a custom css file for your map at src/lib/map.css and copy and paste the css code from GitHub to your new file. You might find it helpful to reference the code on GitHub and this post simultaneously to see the code snippets in context of the larger project. Here is an outline of what that final page structure will look like once we complete all the steps below. GetVisibleMarkers and to the map page itself. We are going to add our logic to separate functional components, e.g. In v3.0 accessing the map element is simplified in a react hook, however this also means that you need to be inside the MapContainer component to use the hook. In 2.x.x you can create a ref with useRef to the map component and then use this ref to access the leaflet map element. The biggest change in my experience was how you access the leaflet map element, and its child objects like layers and panes. I originally wrote the majority of this code for v2.x.x of react-leaflet and had to update it to work with v3.0. This code is for react-leaflet v3.0 which was a fairly major change from v2.x.x and involves a switch to a hooks based API. data changes after filtering), dynamically showing only the results that are visible in the viewport, and finally adding a “locate me” button. In this section I am going to talk about clustering map markers, implementing custom marker popups, dynamic map data (e.g. This is where the code complexity starts to ramp up. In order to help users find what they are looking for most mapping applications implement a robust searching and filtering UI. Mapping applications have become ubiquitous in our lives whether it is for driving directions, restaurant reviews, or booking a hotel room. The core purpose of mapping applications is to visualize geographical data that would otherwise be too difficult to understand. I reviewed a few different options and ended up going with MapBox for my projects but there are lots of different options to choose from. This is fine for testing or development but in production you will need to use, and pay, for a map tile service. In the demo code you will notice that I am using OpenStreetMap tiles. Now that we have a basic map we can start building the more advanced functionality our real estate app needs. This has tripped me up more than a few times! The second gotcha we cover below and has to do with dynamic data. The standard coordinate format in GeoJson and react-leaflet is different for GeoJson coordinates are stored as whereas react-leaflet uses coordinates in the format. There are two gotchas worth noting here with GeoJson in react-leaflet. The GeoJson component automatically creates the markers for us - now we are getting somewhere! Save and refresh your browser, you should see our new markers on the map. Here we are using Gatsby Theme Catalyst (but you can use any starter you want) to quickly bootstrap a working Gatsby project. In a real world application your geolocation data would be coming from an API/backend of some kind. We are going to setup a quick starter project, add our dependencies, display a basic map and then add some imaginary placeholder data. If you are already familiar with react-leaflet you can likely skip straight to part 2 where we begin covering the more advanced mapping topics. Most of the code in this post is just plain React and would be transferable with to other React based frameworks, e.g. I focus almost entirely on the javascript side of things in this post so what we build ain’t pretty! There just isn’t space here to explain what hooks like useState or useEffect do. I assume you have a basic familiarity with Gatsby and React hooks - but do my best to walk you through things. If you want to see a production version of this code you can poke around A couple of notes before we get going:

We are using v3.0 of react-leaflet which was released at the end of 2020 - this code won’t work for v2 but I have working code for v2 of react-leaflet so feel free to ask me questions. Hang on to your hats - this is a blustery one! In this post we walk through creating an imaginary real estate mapping app using Gatsby and React Leaflet.
