Configuring Webpack for react-pdf in Next.js

If you're using the react-pdf library in your Next.js project to generate, view, and download PDFs on the client side, you might face some challenges with Webpack configuration. Especially if you are not well-versed in the intricacies of Webpack, it can lead to frustration. In this guide, we will guide you through the necessary steps to effectively configure Webpack for your Next.js application to integrate react-pdf.

The Problem

When incorporating libraries like react-pdf, which rely on certain Node.js modules, you may encounter errors associated with missing modules during the build process. This is primarily because Next.js does not directly support certain Node.js features in the browser environment, necessitating some adjustments in the Webpack configuration.

To smoothly run the react-pdf library in your Next.js application without a server, a specific setup in your Webpack configuration is required.

The Required Webpack Configuration

The following sections break down the configuration needed to integrate react-pdf fully:

Step 1: Modify the next.config.js

In Next.js, you can customize the Webpack configuration through the next.config.js file. Below is a sample setup:

Step 2: Breakdown of Key Configuration Sections

Fallback Configuration:

Here, we provide polyfills for the core Node.js modules that react-pdf relies on to function properly in a browser environment.

Each line under config.resolve.fallback maps a Node.js module to its browser-compatible equivalent.

Provide Plugin:

The ProvidePlugin automatically loads the specified modules whenever they are referenced, making sure that Buffer and process can be accessed in your application.

Returning the Config:

At the end of the function, we return the modified configuration to ensure Next.js picks up the changes.

Additional Considerations

Development vs. Production: When configuring for production, ensure that you test thoroughly as certain polyfills may behave differently than their Node.js counterparts.

Keep Dependencies Updated: Regularly check and update the versions of react-pdf, webpack, and any related libraries in your project to benefit from new features and bug fixes.

Conclusion

With these configurations in place, you can harness the full power of the react-pdf library within your Next.js application. Now, you can generate, view, and download PDFs seamlessly on the client side!
