Enable Partitioned Cookies in Express Application
The Partitioned attribute is not set when calling res.cookie() in an Express application, which prevents the creation of partitioned cookies as per the new privacy standards. This occurs because the default cookie options do not include the partitioned attribute, which is necessary for compliance with the latest browser policies regarding third-party cookies.

Update Cookie Options
Modify the cookie options in your Express application to include the 'Partitioned' attribute. This is essential for ensuring that cookies are treated as partitioned cookies by the browser.
javascriptres.cookie('cookieName', 'cookieValue', { partitioned: true }); - 2
Test Cookie Creation
After updating the cookie options, create a test route in your Express application to set a partitioned cookie. This will help verify that the changes are correctly implemented.
javascriptapp.get('/set-cookie', (req, res) => { res.cookie('testCookie', 'testValue', { partitioned: true }); res.send('Cookie set!'); }); - 3
Verify Cookie in Browser
Use the browser's developer tools to check if the cookie is created with the 'Partitioned' attribute. Navigate to the 'Application' tab, and inspect the cookies under your domain.

Check for Compatibility
Ensure that the browser being used supports partitioned cookies. Refer to the latest browser documentation to confirm compatibility with partitioned cookies.
Validation
To confirm the fix worked, check the browser's developer tools under the 'Application' tab and ensure that the cookie created has the 'Partitioned' attribute set. Additionally, test the functionality of the application to ensure cookies are being sent and received as expected.
