samesite cookie nodejs

Step 1: Install 'cookie-parser' module using npm by running the command 'npm install cookie-parser' in the terminal.

Step 2: Import the 'cookie-parser' module in the Node.js application by adding the following line of code: 'const cookieParser = require('cookie-parser');'

Step 3: Use the 'cookie-parser' middleware in the Node.js application by adding the following line of code: 'app.use(cookieParser());'

Step 4: Set the 'sameSite' attribute for the cookie by including it as an option when setting the cookie using the 'res.cookie' method. For example: 'res.cookie('cookieName', 'cookieValue', { sameSite: 'strict' });'

Step 5: Configure the Node.js application to send cookies with the 'sameSite' attribute by setting the 'secure' attribute to 'true' when deploying the application in a production environment. For example: 'app.set('trust proxy', 1);' and 'app.use(cookieParser());'

Step 6: Test the Node.js application to ensure that the 'sameSite' attribute is set correctly for the cookies by sending requests and inspecting the cookies in the browser developer tools or using a tool like Postman.

Step 7: Monitor and handle any potential issues that may arise with the 'sameSite' attribute configuration, such as compatibility issues with older browsers or cross-site requests.
