bref-image-resizer

When an image is uploaded to the S3 bucket, then this lambda is triggered which will create a thumbnail version and upload it back into the S3 bucket.

Installation

• Copy Makefile.dist to Makefile and change UNIQUE_KEY.
• composer install
• make setup
• make deploy

To run

• Upload an image file into your -images bucket.
• Wait a second or two.
• List the files in the S3 bucket and see that the -thumb version now exists. (Check the logs if it doesn't turn up using make lastlog.)

Notes

• This function uses Bref.
• This function needs Imagick which is provided by a separate layer.
• This function is called by S3 whenever a new file is added to the bucket, so we have to check that we don't resize the thumbnail files!
