Dependency

client-compress - A JavaScript client side image compression library. This library uses the Canvas API to compress the image, and thus will not work on the node.js server-side. This library is forked from compress.js. This version has been updated to use the latest packages, uses async/await, fixes bugs, offers more options and a cleaner API.
