React app not receiving cookies from server after authentication

Backend
1

I’m having trouble with my React app not receiving cookies from the backend after successful authentication. Here’s what’s happening:

  1. When I enter the correct login info, my server sends a JWT token in a cookie.
  2. I can see the cookie in the server response when testing with Postman.
  3. However, when I check the Network tab in my React app, no cookies are showing up.

I’m using axios for the POST request like this:

const login = async (username, password) => {
  try {
    const response = await axios.post('/api/login', { username, password }, { withCredentials: true });
    console.log(response);
  } catch (error) {
    console.error('Login failed:', error);
  }
};

I’ve double-checked that I’m sending the correct login details from the React app. Any ideas why the cookies aren’t making it to the frontend? Could it be a CORS issue or something with my axios setup?

hey mate, have u tried clearing browser cache? sometimes that can mess with cookies. also, double-check ur server’s response headers. make sure Access-Control-Allow-Credentials is set to true. if that doesn’t work, maybe try using a different http client like fetch instead of axios? just a thought

I’ve encountered a similar issue before, and it turned out to be a CORS configuration problem. Make sure your backend is set up to allow credentials and that the origin is properly specified. Check your server-side CORS settings, particularly the ‘credentials’ and ‘origin’ options.

Also, verify that your server is setting the ‘SameSite’ and ‘Secure’ attributes on the cookie correctly. Modern browsers have strict security policies, and if these aren’t set properly, the cookie might be blocked.

Lastly, ensure your frontend and backend are running on the same domain or that you’ve properly configured your proxy settings in your React app. Sometimes, domain mismatches can prevent cookies from being set correctly in the browser.

If none of these solve the issue, consider using browser dev tools to debug further. The Application tab can show you detailed cookie information and help pinpoint where the problem lies.

hm, interesting issue! have you checked if the cookie is HttpOnly? that could explain why it’s not visible in the browser. also, what about the cookie’s domain? make sure it matches your app’s domain exactly. oh, and are you using any ad blockers? they can sometimes interfere with cookies. what other troubleshooting steps have you tried?
