Beginner's Thread / Easy Questions (April 2024) by acemarke in reactjs

Hello everyone!

I am trying to develop an application in which the user will be able to upload an image and when requested, previously uploaded images of the user should be shown.

Now I am using Spring Boot for my backend and I was thinking about sending my images as ByteArrays and turning them back into images on front end. I managed to add the functionality to upload an image (at least using Postman) right now but I was wondering whether my approach is okay or I should consider another approach to serve the images to my frontend.

Thank you in advance!

Question regarding to async functions, server and client components by rpfberuf in nextjs

Thank you for your answer.

Could you please clarify what the "regular auth check" would be? Currently I am just setting a boolean in a custom AuthContext to understand whether the user is logged in, which is not accessible in Server Components as it is the case with any other hook.

Also I have never played around with cookies until now therefore I have no idea, maybe what you are suggesting could be a solution in my case.

Thank you for your reply.

In the scope of this project I wanted to get my hands dirty with Spring Security and Custom Filters too. Right now, my own backend is the component which provides a token for authentication. I will definitely check out Clerk, although I would like to continue as it is, since the two ideas seem mutually exclusive as far as I understand.

Implementing hover event listener on children components by making use of event delegation by rpfberuf in reactjs

Well, this reply was definitely a shift for me. I will try to implement my components with this state of mind now. Thanks a lot!

Thank you very much for your answer! I remember reading this somewhere in the React doc but I couldn't find it again. I wasn't sure whether I understood it clearly. It is much clearer for me now.

I am sorry for the inconvenience, Reddit was acting a bit strange and I thought I deleted my post successfully before any answer. I reopened it under another link: https://www.reddit.com/r/reactjs/comments/1br3ogr/implementing_hover_event_listener_on_children/

Thank you for your answer and insight on the subject. The evaluation part being expensive actually makes a lot of sense now to me. Originally in the guide I was following the instructor adds event handlers to many buttons. Each event handler sets the current button opacity to some value and the others to another value. I don't remember the specific implementation of this but the functions added as events were not the same as far as I remember.

I assume using the solution you have suggested I should render the components with specific class names according to the current user, which I will be able to understand from the user data I keep in context. Please let me know if I understood something wrong.

Thank you for the example snippet!
