Upload Files

Our application’s business logic mainly depends on uploading files because we’re building an application that we can treat as though it were our own private library. Uploading files allows us to extend the application’s functionality as much as we want. We can use that functionality to manipulate our files and organize them.

Prerequisites

We’ll use Multer, a well-known npm package, which is used as middleware for uploading files. To configure uploading files to our server, we need to install the following:

• The multer handles files that are uploading to the server.
• The body-parser parses Multer’s middleware into the request body.

Let’s configure the body-parser in index.js.
