How to Use react-leaflet-easyprint with react-leaflet 3

If you have recently upgraded your mapping application to use react-leaflet version 3, you might have encountered some challenges when trying to implement the react-leaflet-easyprint package. This package, which works seamlessly with earlier versions of react-leaflet, seems to be incompatible with version 3 right out of the box. But don’t worry—there's a solution! In this guide, we'll explore how to make easyprint work with the latest version of react-leaflet by using a JavaScript implementation instead of the React wrapper. Let's dive into how to achieve this integration.

Understanding the Problem

As web developers know, react-leaflet is a popular library for integrating Leaflet maps in React applications. The react-leaflet-easyprint package is a great tool for adding print functionalities to your maps. However, until recently, its documentation and examples primarily focused on versions 1 and 2 of react-leaflet, making it a bit tricky for those who have transitioned to version 3. The incompatibility could stop you from providing users with the ability to easily print or export the maps you've skilfully created.

The Solution: Utilize Leaflet's Easy Print Directly

Instead of relying on the react-leaflet-easyprint wrapper, we can utilize the base functionality provided by the leaflet-easyprint package directly within a React component. Below are the detailed steps to implement this solution.

Step 1: Install Required Packages

Start by ensuring you have the necessary packages installed in your project. In your package.json, you should have the following dependencies:

Step 2: Create the MapPrint Component

Now, let's create a new React component named MapPrint.js. This component will handle the integration of the easy print functionality into your map.

Step 3: Integrate MapPrint into your MapContainer

Finally, integrate your new MapPrint component within the MapContainer from react-leaflet. You can specify the position and modes to control how your print functionality operates.

Conclusion

By leveraging the leaflet-easyprint library directly within your React components, you can easily integrate print functionalities with react-leaflet version 3. This method provides you more control and flexibility compared to relying purely on a React wrapper. Now, users of your mapping applications can efficiently print or export maps as needed!
