Response vs Request Cookies Explained

response.cookie and request.cookie are two commonly used objects in web development, representing the cookies in the server response and client request respectively.

1. response.cookie is an object or method used to set cookies when sending a response from the server. By calling the response.cookie() method, you can set cookies that will be sent to the client in the response. For example, in the Express framework, you can set cookies like this:
2. Create a cookie with the name “cookieName” and the value “cookieValue”.
3. This will add a Cookie with the name cookieName and the value cookieValue in the response header.
4. request.cookie: This is an object or property used to retrieve the Cookies in the client’s request when sending a request. By accessing the request.cookie object or property, you can obtain the Cookie information carried in the client’s request. For example, in the Express framework, you can retrieve the Cookie using the following method.
5. Set the cookieValue variable to the value stored in the cookieName cookie of the request.
6. This will retrieve the value of a cookie named cookieName from the request and assign it to the variable cookieValue.

In summary, response.cookie is used to set cookies in the server’s response, while request.cookie is used to retrieve cookies from the client’s request. They perform different functions in different contexts, but both involve handling cookies.
