Creating an image handling middleware

- [Instructor] In this video,…we will instantiate the previously created class…and create the middleware that utilizes it…to handle our uploads.…First, we need to make an instance of this class…available in our routes,…and they are already built in a way…that they can accept arguments passed on…from other parts of the application.…We can start in server,…app.js,…and there, right after the feedback service on line 13,…I now add const AvatarService…equals require…services/AvatarService.…

Then, a little bit further down,…I will now add to line 19…const avatars…equals new…AvatarService,…and we pass in the path…where we want to store the images…and its config…data…avatars.…Why can we do that?…Because the sample project already has this set.…In the config file,…there is already a path for the avatars defined,…and this points to data, avatars,…so all images will be stored in this directory.…

Next, we have to pass avatars down our routing chain,…so I'm scrolling down…until we have this app.use here,…and here, I'm simply passing in avatars.…
