Problem Deploying to Vercel using Plaiceholder, Sharp, and NextJS 14? Don’t Worry, We’ve Got You Covered!

Are you stuck in the dark alleys of deployment errors, wondering why your NextJS 14 application, beautifully crafted with Plaiceholder and Sharp, refuses to deploy on Vercel? Fear not, dear developer, for you’re not alone in this struggle. In this article, we’ll guide you through the common issues, fixes, and best practices to get your application up and running on Vercel in no time.

The Problem: Plaiceholder and Sharp Incompatibility

The main culprit behind the deployment errors is the incompatibility between Plaiceholder, Sharp, and NextJS 14. Plaiceholder, a popular image optimization library, relies heavily on Sharp, a fast and powerful image processing library. However, NextJS 14 introduces some breaking changes that affect the way Sharp is used, leading to deployment issues on Vercel.

Symptoms of the Problem

• Error messages indicating Sharp version incompatibility
• Fatal errors during the deployment process
• Images not being optimized or processed correctly

Step 1: Update Your Dependencies

The first step in resolving the deployment issue is to update your dependencies to compatible versions. Make sure you’re running the latest versions of NextJS, Plaiceholder, and Sharp.

  // package.json
  {
    "dependencies": {
      "next": "^14.0.0",
      "plaiceholder": "^1.3.0",
      "sharp": "^0.30.0"
    }
  }

Step 2: Configure Sharp for NextJS 14

Next, you need to configure Sharp to work seamlessly with NextJS 14. Add the following code to your `next.config.js` file:

  // next.config.js
  module.exports = {
    //...
    experimental: {
      images: {
        allowFutureImages: true,
      },
    },
    //...
  };

This configuration ensures that Sharp is used correctly with NextJS 14.

Step 3: Use the Correct Plaiceholder Configuration

Now, it’s time to configure Plaiceholder to work with Sharp and NextJS 14. Update your `plaiceholder.config.js` file with the following code:

  // plaiceholder.config.js
  module.exports = {
    //...
    sharp: {
      enabled: true,
      fallback: 'png',
      pngquant: {
        quality: [0.5, 0.75],
      },
    },
    //...
  };

This configuration enables Sharp processing and sets the fallback image format to PNG.

Step 4: Optimize Images with Plaiceholder and Sharp

With the configurations in place, you can now use Plaiceholder to optimize your images. Here’s an example of how to use Plaiceholder with Sharp to optimize an image:

  // pages/image.js
  import Image from 'next/image';
  import plaiceholder from 'plaiceholder';

  const image = await plaiceholder('image.jpg', {
    sharp: {
      resize: {
        width: 800,
        height: 600,
      },
    },
  });

  return (
    <
      Image
      src={image.src}
      width={image.width}
      height={image.height}
      alt="Example Image"
    />
  );

Step 5: Verify Your Deployment

After completing the above steps, redeploy your application to Vercel. Verify that the images are being optimized correctly by checking the asset sizes and image quality.

Troubleshooting Common Issues

If you’re still experiencing issues, check the following common problems and solutions:

Error Message	Solution
Sharp version incompatibility	Update Sharp to the latest version (≥ 0.30.0)
Fatal error during deployment	Check your `next.config.js` and `plaiceholder.config.js` files for syntax errors
Images not being optimized	Verify that Plaiceholder is configured correctly and Sharp is enabled

Conclusion

Deploying a NextJS 14 application with Plaiceholder and Sharp on Vercel can be a challenging task, but by following these steps and troubleshooting common issues, you should be able to overcome the problems and successfully deploy your application. Remember to keep your dependencies up-to-date and configure Sharp and Plaiceholder correctly to ensure a seamless deployment experience.
