Image resize API

TL;DR

A simple API that just resizes images and returns as webp.

• ENVIRONMENT: The environment in which the application is running
  • dev: Development environment (default, allows url to be any)
• MAX_AGE: The maximum age of the cache
• S_MAX_AGE: The maximum age of the cache for shared caches
• ALLOWED_ORIGINS: The allowed origins for CORS

Supported image formats (to be resized)

• JPEG
• PNG

Or any other format will be just returned as is.
