I've implemented the router and everything works (navigation etc.) but how can I make sure that when I want to go to http://myapp.dev/members that the url is handled by react (router)? When I type that URL in my browser now, nothing happens, because the /members doesnt exist (backend)

You need to redirect your backend to wherever your react application is. react-router themselves have it in their documentation. If you're on nginx, use a try_files rule to try, see if it exists, and if not, fire back to wherever your react app is.
The same goes for Apache using rewrite rules.
Both are actually very well documented within the doc.

https not defined
Even after adding
const https=require("https");
The issue ain't getting resolved .
Does http:// work? If it does, the site you are attempting to connect to might not be secure. https:// only works if the site information is encrypted.
You gave const https=require("https");, but I don't know the context of what you are attempting to use it for, so this is hard to answer.
Are you using that variable out of scope?

I was using netlify to deploy my app and I noticed that we cant access website using manual routes, and results in displaying 404 :
https://edurekaclone.netlify.app => WORKS
https://edurekaclone.netlify.app/courses/5b21ca3eet4r6fbccd471815 =>Does not works
Even simple routes when visited manually like /login, are not working
We have to First visit homepage and navigate to other routes/pages from there only.
I am using react-router-dom and its purely frontend without any server
I found the fix, in documentation as mentioned by #jonsharpe, Thanks
Basically you need a rewrite rule here which should be present in build/ folder, and would enable to access clean URLs
->>
1. Add _redirects file in public/ folder
2. Inside _redirects add /* /index.html 200
->>
and Voila!
This will also be reflected in the build deploy summary and logs

I have a problem, I need to open a pwa app through a link but I need to send it as a parameter as an ID so that the pwa app behaves differently depending on the ID, but I have no idea how to do that, can you help me? I'm using the expo SDK version 39 react-native.
I think you are referring to Deep Linking, here is a snippet from the react native doc: https://reactnative.dev/docs/linking
Handling Deep Links
There are two ways to handle URLs that open your app.
If the app is already open, the app is foregrounded and a Linking event is fired
You can handle these events with Linking.addEventListener(url, callback).
If the app is not already open, it is opened and the url is passed in as the initialURL
You can handle these events with Linking.getInitialURL(url) -- it returns a Promise that resolves to the url, if there is one.

On this site, which is on Joomla and using a plugin called Matukio, the links on the left used to work, but no longer do and we are desperate to figure out why.
The company who makes the plugin replied with this info, but it sounds like he's just spouting a bunch of stuff that isn't really the cause (JUri::root() is working fine, the VWO stuff was there before when the links worked, etc).
I doubt anyone can give much insight based on this limited info, but just taking a shot bc stackoverflow is literally the best site on the internet for help. If anyone has any ideas on things i should look at, test, please share...
FROM MATUKIO:
you have JavaScript errors on your page (not caused by Matukio):
07:43:49.475 ReferenceError: Heatmap is not defined
<anonym>events:129
1events:129:3
ga('set', 'VWO', Heatmap);
Additionally the following is failing:
07:44:55.490 Loading of mixed contents "http://www.workwave.com/index.php?option=com_matukio&view=requests&format=raw&task=route_link&link=index.php%3FItemid%3D283%26option%3Dcom_matukio%26view%3Deventlist%26art%3D0%26catids%3D0%26search%3D%26limit%3D10%26dateid%3D2%26fees%3D0%26locations%3D0%26organizers%3D0%26ordering%3D1%26start%3D0&Itemid=283" was blocked .1jquery.min.js:5:25679
As you see the link looks right, but hte protocol is wrong. E.g. http
instead of https.. Are you using any plugin for https redirection? Or
htaccess? It seems that JUri::root() is not working correct on your
instance. Joomla has a setting for https in the global config.
Kind regards,
Yves
It's hard to tell without more information but it looks like your site is using HTTPS. This is a good thing. But one of the restrictions is that if you're using a secure connection, then you can't access resources that are stored on a server using the non-secure HTTP protocol (it's kind of buying a fancy lock for your front door and then leaving the window open.)
This is likely coming from the Heatmap library. If you're pull this library from a CDN, try changing the url to "https://" instead of "http://" and this should fix it.

So I'm trying to create a JavaScript code for a button that allows me to login to a website that I have created. I have my database that the information will be retrieving the verification from. I just can't seem to get the functionality to the button to do such a thing. So far all I have done was trying to reverse engineer the Facebook code login button but yet all I had on my hands after that was a big mess. I know I'm a bit over my head in this situation. JavaScript isn't my best language. I have a button right now and that's it.
This is not a JavaScript question but a design question.
You are dealing with three levels here. In brief -
View - Your html (button), css & JS
Controller - Your space for action, validation and logic
Data - Your data stored in your DB
You've got the view (partially) and the Data layers figured out; however, you haven't worked on your controller layer.
Your controller layer should consume the data from the view (login details), validate the data, transform (if necessary) and authenticate against the DB.
You can build your controller on the server (Java, nodeJS, etc.) or on the client (JavaScript AJAX).
Hence, I suggest you figure out where do you want your code to live - on your server or in the browser. You should also keep in mind security.
