Implementing Image Transformation Service with NextJS and imgproxy
Introduction imgproxy is an efficient image processing and optimization service, featuring fast processing speeds, high security and low memory footprints because it is written in Go. The prominent advantages of imgproxy include the ability to resize, crop, compress and flexibly convert image formats (such as to WebP, AVIF) via URL. Notably, this service supports secure URL signing using HMAC encryption, which prevents DDoS attacks or unauthorized modifications of image size parameters from the client side. Although the NextJS Image component already supports automatic image resizing, it presents several limitations if you choose it for large-scale deployment Resized images stored in the cache of the .next folder only exist within a single NextJS server instance, making it difficult to share the cache when scaling up to multiple instances After building the project, the cache data is lost, or if you find a way to persist these resized images, a large dataset will still consume too much...
