API Project: File Metadata Microservice for freeCodeCamp User stories: I can submit a form that includes a file upload. The form file input field has the "name" attribute set to "upfile". We rely on this in testing. When I submit something, I will receive the file name and size in bytes within the JSON response Usage : Go to the main page, and upload a file using the provided form. Hint: To handle the file uploading you should use the multer npm package.
