STOP Storing Images in Your Server🚫Best Way to Upload Files in Next.js (UploadThing Guide)

Описание: In this Next.js + MySQL Job Portal App (Video #51), I’m going to teach you the correct, professional, and scalable way to upload images and files in your application using UploadThing.

Most beginners make one big mistake:
👉 They store images directly in their own servers or databases.
This slows down the server, increases cost, reduces performance, and is never recommended for production.

In this video, you will learn how professionals handle file uploads:

Upload images to a dedicated storage service

Receive a secure public URL

Use that URL in your database instead of storing the image file

Keep your database lightweight, fast, and cheap

Today’s goal:
✔ Connect UploadThing with our Next.js app
✔ Configure environment variables
✔ Build fileRouter + API route
✔ Use the UploadButton in the frontend
✔ Receive an image URL on upload
✔ Understand important events like onUploadComplete

In the next video, we will store this generated URL inside our MySQL database for the Job Portal app.
