Currently my CI system generates production assets using webpack (js, css, images and svgs) and uploads them to s3 using the s3 sync command on every deployment.

According to the s3 docs,

A local file will require uploading if the size of the local file is different than the size of the s3 object, the last modified time of the local file is newer than the last modified time of the s3 object, or the local file does not exist under the specified bucket and prefix.

Since the CI system builds the assets on every deployment, would all the assets be uploaded on every deployment since the last modified time is always going to be different?

If yes, is there a way around this? Would love to get some input on this. 🙂
