Read input from many child components
I have a page with hundreds of text fields. From the page, I'm trying to read the user's input from each field when they click on a button.
useState can work but would be too slow
What would be a better solution? Should/how do I use useRef in this case?...Does CRA have any weird issues with rendering images?
I know I shouldnt even be using CRA, im moving off of it, so dont yell at me lol. But is rendering images a known issue that it has??
Are there any examples on how to implement web notifications?
If, for example, a User A leaves a comment on User B's photo, how do I show a notification to User B? I would need to know if User B has seen the comment or not. How would I check that?
I'm assuming I would need a Notifications Table in my database with a one-to-many relationship. Where each user would have one notification table with many notifications. The notifications would have to get deleted automatically once the user sees the new comment.
Are there any examples that show how to implement such a system?...
Prisma query failing in NextJS deployment
I have a NextJS project which is using prisma and Planetscale. I have a webhook from Stripe where I read from one table and then write to another. The first prisma query always seems to fail. I have added other random queries before it, but it is always the first one which fails. After that failure/timeout (~5mins) the next request always runs instantly. When running locally everything works totally fine, but it always fails when deployed.
I am using global.prisma to ensure there is only one PrismaClient in the entire project (as described here)
I think this might be connection pool issue because the error message is this (but I'm not sure why this would be the problem):...

Prisma sort by latest post to a thread
Hi everyone, trying to return a list of "threads" which have lots of "posts" on them. I'm trying to write a query that will return the x most recently updated threads by sorting on their latest post.
I've tried using take: 1, and _max on the relation and a few other things but it feels like I'm missing something. Feels like it should be fairly trivial but I just can't figure out an easy way to do it in the query.
Any ideas for this pattern? (I'm abstracting a bit, my objects are named a bit differently but the pattern is the same)....
functional components vs functions that return jsx
Are functions that return jsx in your component an anti pattern? Is it usually better to abstract these into another component outside of your current one?
infinite render with server fetch hook I wrote

Image Fetching bug with NextJS
So I'm trying to load in a set of profile pictures for a list of contributors to a repo. I have a list of everyone's github handle's. I'm fetching the profile pictures like so
Their are a few github handle's that were submitted incorrectly, so I'm trying to replace those images with a default thumbnail using the onError callback: ...
<img className="mx-auto h-20 w-20 rounded-full lg:h-24 lg:w-24" src={`https://github.com/${person[1]}.png`} onError={(e) => replace(e)} />
<img className="mx-auto h-20 w-20 rounded-full lg:h-24 lg:w-24" src={`https://github.com/${person[1]}.png`} onError={(e) => replace(e)} />

Is there a way on NextAuth to redirect upon login to a specific page based on session role?
E.g.
- If session.role === 'teacher', redirect to '/teacher/dashboard', else
- redirect to '/admin/dashboard'
The NextAuth docs don't show a way to redirect based on session data: https://next-auth.js.org/configuration/callbacks#redirect-callback...
Best Practices - separating business logic from UI
So, I've seen this pattern which the Business logic is put into a hook, so it doesn't bloat the component.
I've also seen that some critics that having the business logic into the component is wrong
Here's a stackoverflow thread that illustrates well what I'm talking about:
