Resizing and storing images with sharp

- [Narrator] By now, we have a buffer…that contains our image data…and some meetup information for the image.…In this video, we will convert the image to PNG,…to not having to deal with different file formats,…and we shrink the image to a maximum size needed…on our page to save some disk space.…There are several modules that deal…with image manipulation available;…I personally prefer sharp.…It provides plenty of image manipulation methods…and a good performance.…So let's install it now by running npm install --save sharp,…and we will need image manipulation functions…on different places,…so it makes sense to create this service class for that.…

So I will now go into server, services,…and there I create a new file: AvatarService.js.…There, of course, first,…bring const sharp = require('sharp'),…and we need need a few more modules,…because I want to automatically create file names.…For that, we will use uuidv4 = require('uuid'),…and we take the version four here,…and we need util,…and also we will need path to deal with file path,…
