In React.js, you can use the
document.cookie
property to set cookies on a specific domain. If you want to set a cookie on a subdomain, you can use thedomain
option when setting the cookie. For example, if your main domain isexample.com
and you want to set a cookie on thesubdomain.example.com
subdomain, you can use the following code:This will set a cookie named
myCookie
with the valuevalue
on thesubdomain.example.com
subdomain. Thepath
option is used to specify the path on the domain for which the cookie is valid. In this case, thepath
is set to the root directory, so the cookie will be valid for the entire subdomain.To send a cookie from the main domain to a subdomain in a React.js application, you can use the
setCookie
method provided by thejs-cookie
library. This method allows you to set a cookie on the current domain and specify adomain
parameter to indicate which subdomain(s) the cookie should be sent to. For example, the following code would set a cookie namedmyCookie
on the main domain and send it to thesubdomain.example.com
subdomain:Note that in order for this to work, the
domain
parameter must include the leading.
character, which indicates that the cookie should be sent to all subdomains of the specified domain.In React.js, you can use the
js-cookie
library to set a cookie on the main domain that can be accessed by a subdomain. Here’s an example of how to use theset
method to set a cookie named “example” with a value of “hello” on the main domain and make it accessible to all subdomains:import Cookies from 'js-cookie';
Cookies.set('example', 'hello', { domain: '.yourmaindomain.com' });
You can also use the
get
method to retrieve the value of a cookie on the subdomain:const example = Cookies.get('example');
console.log(example); // "hello"
Make sure that the domain value is same as your main domain so that the cookie can be accessed in subdomain
