cor | Straightforward language for the Web | Runtime Evironment library

Hi am trying to do a CRUD application am able to do the add user but i got stock with the edit user Actually for my edit user page i just copied the add user page there and then modified it

This is what my app has to do: normally when i enter the edit user page it has to show me the user's existing information then on my part i can now modify it if i wish and then it is stored in my mysql database but it doesn't return anything i actually console logged it to see if it returns anything but it doesn't

I have my own API wrote in Play Scala and frontend client wrote in react.js I can't send logout request (I use OAuth2), because i get error with cors headers. I tried to fix it but i can't.

My react fetch method:

so im developing website using nodejs, and then deploying it to microsoft azure, and using Azure Database for mysql server to be exact, and importing my databse using mysql workbench, now the problem is in the CORS, everyhting going well i run it on chrome and firefox in the same pc works fine, but when i try to acces the website using another pc, i get the error says "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:3000/data/price%20asc. (Reason: CORS request did not succeed)".

heres my nodejs code:

I am a python developer, but there is a small part that I need to complete in Javascript, I am unable to figure it out.

This needs to be done in a local computer only. I have a .csv file with two columns, and I Need to make a real-time line chart (it reads csv file every X seconds and refresh).

I tried some code from online, they work only with real url. My file is local, so I get this error in all the code I tried by copy/pasting.

Access to XMLHttpRequest at 'file:///C:/Programs/Stock/test.csv' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, chrome-untrusted, https.

It would be great, If someone can help me with this, otherwise I need to learn Javascript from scratch.

I am creating my personal website, and I am using live-server, but I get the CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource error. So I review the documentation, and they recommend adding --cors flag to enable cors for any origin, I did it, but the same error appears.

By the way, that's happened, especially with the font awesome script kit.

Any solutions do you want to provide me? Thanks before all.

I'm deleting data from my firebase db with fetch but I can't figure out how to point to an exact ID.

I don't really know where the error is, for me, it's still a mystery. But I'm using Laravel 8 to produce a project, it was working perfectly and randomly started to return this error and all projects started to return this error too. I believe it's something with Redis, as I'm using it to store the system cache. When I go to access my endpoint in postman it returns the following error:

Hello we are trying to implment a Chat feature in our already working applicaiton which is a MERN stack app, we opted to use socket.io because its fairly easy to set up and use,we managed to get it working locally but when we deployed on our dev server the chat wasn't working , we followed this socket.io document to try and solve the problem which served us well when we had the CORS problem locally , https://socket.io/docs/v3/handling-cors/ this is the server side code used :

I'm using a free plan of firebase storage. All working good but the image not loading on my flutter web.
