Persisting chunks on CDN in aws amplify service

To persist chunks on a CDN for Next.js deployment in AWS Amplify, you can follow these steps:

Go to the AWS Amplify console and select your app.

Click on the "App Settings" option in the left navigation pane.

Under the "Build settings" section, click on the "Edit" button next to "Build settings".

Scroll down to the "Environment variables" section and add a new variable called "NEXT_PUBLIC_S3_PREFIX" with a value of your S3 prefix.

Click on the "Save and deploy" button to save your changes and deploy your app.

Once your app is deployed, go to your S3 bucket and create a new folder with the name of your S3 prefix.

Upload your Next.js chunks to the new folder you just created.

Finally, update your Next.js configuration to use the CDN URL for the chunks. You can do this by setting the "assetPrefix" property in your "next.config.js" file to the CDN URL.

With these steps, your Next.js app will be able to retrieve the chunks from the CDN, and they will be persisted across deployments.
