In this collection, you'll learn the basics of creating a new map in your React application with React Leaflet. We'll walk through adding the map itself as well as adding markers with popups, different shapes, and increasingly complex features to your map!

In this lesson, you will learn how to add a map to your React application using React Leaflet. We will walk through importing and configuring the Map and TileLayer components from React Leaflet to set up the new map.

Create a New Map using React Leaflet

In this lesson, you will learn how to add a Marker and Popup component to a Map when using React Leaflet. We'll walk you through importing the components and adding each one to the Map. Additionally, we'll resolve an issue with loading marker images that's inherent to creating a new React Leaflet map in Create React App, which we'll fix by manually importing the image from Leaflet and configuring those images to the marker.

Add a React Leaflet Marker with a Popup to a Map

In this lesson, you will learn how to add the Polygon and Circle shape components to a Map when using React Leaflet. We'll walk you through importing both components, adding each component to the Map, and setting a unique color for each shape.

Add Shapes to a Map in React Leaflet

In this lesson, you'll learn how to style shapes on your map to change the look and feel using React Leaflet's API. We'll use React component props like color and weight on our shapes to change the colors and styles.

Style React Leaflet Shapes using Component Props

In this lesson, you'll learn how to use CSS to style and animate shapes on your React Leaflet map. We'll use the className prop to add a custom class and add CSS to customize our shapes.

Style and Animate a React Leaflet Shape with Custom CSS

In this lesson, you will learn how to use React hooks to interface with the Leaflet Map API in React Leaflet. We'll connect a ref to our Map component using the useRef hook and then use the useEffect hook to access that ref, find our Map instance, and use it to fly to a new location.

In this lesson, you learn how to use the React Leaflet ZoomControl component to add a custom zoom control to your map. We'll walk through removing the default control to avoid duplicates, using the ZoomControl position prop to change its location, and setting custom icons with the zoomInText and zoomOutText props.

Change the React Leaflet Map ZoomControl Location and Icons

In this lesson, you will learn how to add GeoJSON data to a map in React Leaflet. Using the National Parks in the United States, we'll import a GeoJSON document, create a new Leaflet GeoJSON instance, and add a marker with a popup for each park.

Add GeoJSON Location Data to a Map Using Markers and Popups in React Leaflet

In this lesson, we'll use an image to create a custom map marker icon for GeoJSON location data on our map. We'll walk through importing a custom image, creating a new Leaflet Icon and Marker instance, and use them to customize our National Parks markers.

Customize GeoJSON Data Markers with a React Leaflet Icon Image

In this lesson, we'll use the LayerGroup and FeatureGroup components to organize feature shapes on our map. Using these grouping features, we'll learn how the LayerGroup is used for organizational purposes like adding or removing multiple layers at once and how we can update the color of all of our grouped shapes with the color prop on our FeatureGroup.

Manage Map Data and Feature Shapes Together in a React Leaflet LayerGroup or FeatureGroup

In this lesson, we'll add a new tile service as our basemap in React Leaflet. Using the NASA GIBS Blue Marble, we'll update the TileLayer component's url and attribution props to the new service. We'll also add the maxNativeZoom prop which allows us to configure the maximum zoom allowable for the service.

Change the Map Tile Service of a React Leaflet TileLayer Basemap to NASA GIBS Blue Marble

In this lesson, we'll add a LayersControl toggle to allow us to change between multiple TileLayer basemaps in React Leaflet. Using the NASA GIBS Blue Marble, we'll add an additional TileLayer component, wrap our two TileLayers in BaseLayer components, and wrap all of our layers in a LayersControl to toggle our basemaps.

Add a LayersControl Toggle to Switch Between TileLayer Basemaps in React Leaflet

In this lesson, we'll use the Leaflet setView and flyTo methods available on a map instance to change the location of a React Leaflet map. Using buttons to demonstrate, we'll walk through adding the setView method using a position and zoom level as well as the flyTo method which allows us to animate changing the location along with a specified duration.

In this lesson, we'll use geojson.io to add markers and draw shapes to create a GeoJSON document that we can add to our React Leaflet map. We'll walk through drawing the shapes, creating a new file to store the GeoJSON data, importing it to our app, and displaying it on our map with the React Leaflet GeoJSON component.

Use Geojson.io to Draw Custom Marker and Shape Features for a React Leaflet Map

In this lesson, we'll use Leaflet's map locate method to use the browser's API to find the visitor's current location and update the React Leaflet map to that location. We'll walk through what the locate method does, set an event handler to trigger when it locates, and use the accuracy and location data to add a circle to the map designating the area.


Use Leaflet's Geolocation API to Find a Browser's Location to Update a React Leaflet Map

In this lesson, we'll use the Leaflet plugin Leaflet.fullscreen to add native HTML5-based fullscreen mode to a React Leaflet Map. We'll use the fullscreenControl prop on our Map component to enable the toggle control and learn how to listen to the available event fullscreenchange to fire code when the browser enters or exits fullscreen mode.

_Note: The Code Example below won't function properly when clicking the control because of how the CodeSandbox maintains the sandboxed environment._

In this lesson, we'll use the Esri Leaflet Geocoder plugin to add placename search on a React Leaflet map. We'll walk through installing the plugin with yarn or npm, importing the geosearch function from the plugin, and using it to add a new search control to the map. Once added, we'll also set up an event handler to fire custom code with the results data whenever a search is made.

In this lesson, we'll use the Leaflet Antimeridian plugin to fix issues with Leaflet Polylines when crossing the International Date Line. We'll walk through installing the plugin using it's Github source, importing its fix as a WrappedPolyline function, and using it to naturally draw our Leaflet line data on our map.
