Extra module 4 - File Management

Dealing with files and their lifecycle, much like entities.

Now, we shall make another upgrade to our system. Let's allow a product to have images, so that a user may see them on the store page. Here, we'll learn how to manage files, in order to be able to implement this new feature.

Let's then begin by installing the types package for Multer. Multer is the middleware that is encapsulated by Nest to extract files from the request. This package will soon be used for typing files.

yarn add -D @types/multer

And also, if you want files to experiment with during this module, you can obtain some here.
