Painstackingly made Kanban app with React, TypeScript and Tailwind

What are you most proud of, and what would you do differently next time?

This is my second attempt to create this application. The first time, I used Laravel and I made it as a full-stack app. It worked, but it was very clunky, unwieldy and had a lot of bugs. This time, I used completely different stack and this version of the app is so much better! This time, I used local storage and didn't make it a full-stack app but it's okay as it doesn't have to be, considering the use cases. I'm very proud of component structure, custom hook use and animation.

What challenges did you encounter, and how did you overcome them?

I encountered dozens of challenges and had to debug this app multiple times, starting from animation and state management up to optimizing CRUD operation on a state variable with super nested structure. The amount of experience I got from it is immense. It is truly remarkable how fast one can grow when they write all the code by themselves without AI. (I used it only when I was completely stuck but, honestly, AI is pretty bad at React code, at least in my experience).

What specific areas of your project would you like help with?

Can anyone tell me how do you set up email notification on your app in Next.js in a straightforward way? It is not related to this project, but if anyone knowns, tell me please. I did a lot of research and found out that such a simple and straightfoward thing as sending an email (PHP does it natively and for free, by the way) is a whole mumba-dumba in Next.js. You need to spend several hours of your time setting everything up and paying third-parties some fees. Is there a really simple way that I didn't see online?
