Image Upload Config and Endpoint

This video tutorial covers the implementation of image upload functionality using Node.js and multer. It begins with setting up the backend to handle file uploads, creating an API endpoint, and configuring multer for disk storage. The tutorial also includes steps for installing multer, creating upload routes, and implementing file type validation to ensure only images are uploaded. Finally, it demonstrates how to make the uploads folder accessible by setting it as a static folder in Express.

What is the primary purpose of using Multer in a Node.js application?

• To serve static files

• To manage user authentication

• To handle multipart form data, especially file uploads

• To handle JSON data

Which method is used to set the storage engine in Multer?

• multer.memoryStorage()

• multer.cloudStorage()

• multer.fileStorage()

• multer.diskStorage()

What is the purpose of the 'destination' function in Multer's storage configuration?

• To define where the uploaded files should be stored

• To set the file size limit

• To specify the file type

• To encrypt the files

Why is it important to customize the filename in Multer's configuration?

• To improve upload speed

• To make files easier to search

• To prevent overwriting files with the same name

• To ensure files are stored in alphabetical order

What does the 'fileFilter' function in Multer do?

• It encrypts the files before saving

• It checks the file type and MIME type to allow only specific files

• It logs the file upload details

• It compresses the uploaded files

What is the purpose of the 'upload.single()' method in the upload route?

• To specify the file size limit

• To allow multiple file uploads

• To delete a file after upload

• To handle a single file upload

What is returned from the upload route to the frontend?

• The file name

• The file type

• The file path

• The file size

Why do we need to make the uploads folder static in Express?

• To allow the server to delete files automatically

• To enable browser access to the uploaded files

• To encrypt the files for security

• To compress the files for storage

Which Node.js module is used to work with file paths in this tutorial?

• url

• path

• fs

• http

What is the purpose of using 'path.join' in the static folder setup?

• To join different segments of file paths

• To delete files

• To compress files

• To encrypt files
