How to Create a Button to Download a PDF File in Next.js

If you're working with Next.js and want to make it easy for users to download a PDF file with a simple button click, you might run into some hiccups if you’re not familiar with serving static files. In this guide, we'll walk you through the steps necessary to create a button that effectively triggers a PDF download in your Next.js application.

The Problem: Downloading a PDF File

You might encounter a situation like this: you have written a piece of code that works perfectly in React, where you include a button that initiates a PDF download. However, upon transitioning that code to a Next.js environment, you face an error: “Failed - No file.” This can be frustrating, but understanding how to properly serve static files within Next.js will help you resolve this issue.

The Solution: Serving Your PDF File Correctly

Step 1: Place Your PDF File in the Public Folder

When working in a Next.js application, any static assets such as PDFs, images, or fonts need to reside in the public folder. By placing your file here, you ensure that it's accessible when the application is built and served.

For example: If your PDF file is named cv.pdf, you should place it in the directory as follows:

Step 2: Create Your Download Link

Once your PDF file is in place, you will need to modify your anchor tag to reference the file correctly. Here's what the code should look like:

Understanding the Code

<a href="/cv.pdf">: This attribute specifies the link to your PDF file, relative to the public folder. The leading slash indicates that it will be found at the root level of the project.

download="cv": This attribute suggests a filename for the downloaded file. When the user clicks on the link, it will prompt them to download the file with the name you specified.

Optional: Serving from a CDN

If you're opting to serve your PDF from a CDN, make sure that the link you are using is valid. Here’s how to format the anchor tag for a CDN:

Important Note

Ensure the path you provide in the href attribute is correct. If the PDF file is stored in another folder or the file name is misspelled, you will still encounter a downloading error.

Conclusion

By following these steps, you should now be able to integrate a working download button for a PDF file in your Next.js application without issues. Always remember to check your file paths and ensure that the file is served from the appropriate directory.

We hope this guide helps you create smoother and more functional file download experiences within your web applications!
