Which UI do you use?

Custom UI

Pre built UI

Share sessions across sub domains

Sharing sessions across multiple sub domains in SuperTokens can be configured by setting the sessionTokenFrontendDomain attribute of the Session recipe in your frontend code.

Example:

• Your app has two subdomains abc.example.com and xyz.example.com. We assume that the user logs in via example.com
• To enable sharing sessions across example.com, abc.example.com and xyz.example.com the sessionTokenFrontendDomain attribute must be set to .example.com

ReactJS

Important

SuperTokens does not provide non-React UI components. So we will be using the supertokens-auth-react SDK and will inject the React components to show the UI. Therefore, the code snippet below refers to the supertokens-auth-react SDK.

import SuperTokens from "supertokens-auth-react";
import Session from "supertokens-auth-react/recipe/session";

SuperTokens.init({
    appInfo: {
        // ...
        // this should be equal to the domain where the user will see the login UI
        apiDomain: "...",
        appName: "...",
        websiteDomain: "https://example.com"
    },
    recipeList: [
        Session.init({
            sessionTokenFrontendDomain: ".example.com"
        })
    ]
});

    },
    recipeList: [
        Session.init({
            sessionTokenFrontendDomain: ".example.com"
        })
    ]
});

Vue

import SuperTokens from "supertokens-auth-react";
import Session from "supertokens-auth-react/recipe/session";

SuperTokens.init({
    appInfo: {
        // ...
        // this should be equal to the domain where the user will see the login UI
        apiDomain: "...",
        appName: "...",
        websiteDomain: "https://example.com"
    },
    recipeList: [
        Session.init({
            sessionTokenFrontendDomain: ".example.com"
        })
    ]
});

caution

Do not set sessionTokenFrontendDomain to a value that's in the public suffix list (Search for your value without the leading dot). Otherwise session management will not work.
