IMage Delivery (kindof) Network

A simple API in NodeJS to serve images and generate thumbnails.

Usage

First, you will have to export three environment variables:

AWS_ACCESS_KEY_ID=xxx
AWS_SECRET_ACCESS_KEY=xxx
# Both secret and port are optionnal, however changing the secret 
# from the default value is highly encouraged for security reasons.
SECRET=super-secret-secret
PORT=3000

Then you can start the project using CLI:

node index.js --s3-bucket=my-bucket \
  --s3-endpoint=https://s3.example.com \
  --s3-region=eu-west-1 \
  --cache-location=/var/cache/image-proxy \
  --origin=http://localhost:3000

NodeJS rewrite

This project was originally written in Rust, but due to poor performance, this was re-written in NodeJS to take advantages of the streams and LibVips which is used by the Sharp library for image processing.
