What does the backend server listens to??

when u make backend, does your server listen to your pages URL?? that is when u say host your webpage, it is hosted on a url. does the the back listen to THAT url? or the localhost of the machine that hosts the site? The little so knowledge i have about backend thus far, FR and BE communicate with eachother via API. But the question i asked above, this occurred to me when I was thinking about how when u click a link, it redirects user to a certain route.. Now there 2 possible ways that can be done as far as I can think of

We just simply use anchor tags or js with location.href to simply add that route to the Link and redirect. As user lands on that page, static elements r rendered and dynamics infos r fetched using API from the backend and later rendered. In this case i suppose the server can just listen to the machines localhost??...

req.body returns undefined

haya!!. So today i was thinking of trying out backend. and i installed express and nodemon and started working on it. everything seemed to be working fine until I made a form in my html and tried to receive and log data in my server.js. But it seems like req.body always returns undefined . I know the server and client side is working fine cause when I submit, it gives my the error I coded in the server.post(). That means i am indeed sending post req to my server . Here is the github code the...

MERN Stack - Search box returning empty array

Hi. I'm developing a MERN stack web app, and am encountering a problem with my search box where if keywords provided in the search box do not match any product in the database, array returns [], whereas it is supposed to throw an error and therefore trigger react toastify for a 'product not found' notification. I'm unsure whether the problem is in the front or backend part of the project, but I provided all of the files I thought were of use. If anyone could help, I'd be very grateful. Let me kn...

How do I publish a public lib locally without adding a `run` script just for me?

Here's the context: I've built my own public library. I'm also building an app that uses this library. I may need to modify the library to fit the app's use case, and until the dust settles on that effort, I do not want to npm publish the library while I iterate on this use case. When lib is modified, I'd like to publish locally so my app can get the latest code. The only way I know how to do that is to add a npm run build-and-publish-locally-because-i-am-iterating-on-app to lib's package.json. That feels wrong: lib is open source, intended to be used by strangers, and I don't want to accidentally publish that script if I need to fix an unexpected, unrelated lib bug. Is there a better approach to this problem? I don't think I'm the first person to create my own library for my own app. How do most handle this?...

CORS keeps blocking request during preflight on the browser

I'm trying to access my API from the browser but the request is blocked by CORS, with the error "Access to XMLHttpRequest at 'http://localhost/3001/auth/login/staff' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource." I tried adding Access-Control-Allow-Origin to allow headers in Cors config but it's not working, I've tested the endpoint on Postman and it works, I'm attaching screenshots of my code(I don't know how to setup nestjs in code sandbox), here's the link to GitHub https://github.com/johnpatrick254/School-Management-System/ on client-webapp branch Any assistance will be highly appreciated!...
