Simple util for minifying assets in S3

S3 Minify

This script connects to an AWS S3 Bucket that contains images. It will iterate through all keys and look for valid png or jpeg images that it has not yet converted, download and convert them using imagemin, and then upload the minified versions to the same S3 bucket.

Usage

1. Copy .env-sample to a new .env file and fill in the missing variables
2. Run npm install
3. Run node index.js

Example output

Optimized! img1.jpeg reduced from 1.5 MB to 360 KB. (-76%)
Optimized! img2.jpeg reduced from 1.3 MB to 285 KB. (-79%)
Image is already optimized. Skipping.
Optimized! img3.jpeg reduced from 1.6 MB to 233 KB. (-85%)

Notes

S3_BUCKET is both the source and destination bucket. You might want to enable versioning if you are interested in preserving the originals.
