ImageOptimization in Rails 5 ActiveStorage

Question

I'm planning to upgrade Rails to 5.2 in one of my websites and introduce ActiveStorage, as of right now I use Paperclip with paperclip_optimizer. One of the negative sides is that I will lose the optimizer, when replacing paperclip with ActiveStorage. How can I implement automatically image optimization on user uploads in ActiveStorage?

Answer 1

It's possible by creating a custom Variation. There is a good example here:

Answer 2

If you are on AWS you can create Lambda function that can listen to an S3 bucket for uploads, and runs image optimization on the newly uploaded files.
