Client-side JavaScript resizing Modern browsers - both on desktops and mobile devices - are more than capable of doing a bit of additional work. Next.js will start a hot-reloading development environment accessible by default at How to Build the User Interfaceįor our project, we'll want the user interface to upload, crop, and resize images on the home page.
