This is just a simple server I wrote for the nfnt/resize package for Hikari.
For production
The image is on Dockerhub. It needs the following env variables to run:
BUCKET_NAME=The bucket where to get the files from and where to upload them
AWS_ACCESS_KEY_ID=Your aws access key id
AWS_SECRET_ACCESS_KEY=Your aws secret access key
AWS_REGION=the region of the bucket
After that you can hit the endpoint with a query paramter 'key' which is the picture to be resized. It will then produce a thumbnail of max 200x200 and upload it to the same bucket under a folder called /thumb.
