Node.js: image resizing without ImageMagick

Question

I\'m developing a web app on Node.js (+ express 4) where users can set their profile image by uploading it to the server. We already limit the file mimetype and max filesize

Answer 1

If you don't need a large image, you can resize it on the client side before uploading it:

Reading files in JavaScript using the File APIs

Image resizing client-side with javascript before upload to the server

Many users might have a good picture of themselves from a smartphone, and many of them are over 200kB. Note that client-provided data is not to be trusted, so server-side checks still apply.
