Auth redirection

Change redirection path post login#

By default, the user is redirected the the / route on your website post login. To change this, you can use the getRedirectionURL function on the frontend as shown below:

import SuperTokens from "supertokens-auth-react";import EmailPassword from "supertokens-auth-react/recipe/emailpassword";
SuperTokens.init({    appInfo: {        apiDomain: "...",        appName: "...",        websiteDomain: "...",    },    recipeList: [        EmailPassword.init({            getRedirectionURL: async (context) => {                if (context.action === "SUCCESS") {                    if (context.redirectToPath !== undefined) {                        // we are navigating back to where the user was before they authenticated                        return context.redirectToPath;                    }                    return "/dashboard";                }                return undefined;            }        }),    ]});

The user will be redirected to the provided URL on:

  • Successful sign up.
  • Successful sign in.
  • Successful email verification post sign up.
  • If the user is already logged in.

If you want to redirect the user to a different domain, then you can do so by first redirecting them to a specific path using the function above, which further redirects them to the final domain.

Redirect user to the login page#

Use the redirectToAuth({show?: "signin" | "signup", redirectBack?: boolean}?) function to redirect the user to the login screen. For example, you may want to call this function when the user clicks on the login button.

import React from "react";import { redirectToAuth } from "supertokens-auth-react";
function NavBar () {  async function onLogin () {    redirectToAuth();   }  return (    <ul>        <li>Home</li>        <li onClick={onLogin}>Login</li> 
    </ul>  )}
  • Call redirectToAuth({show: "signin"}) to take them to the sign in screen
  • Call redirectToAuth({show: "signup"}) to take them to the sign up screen
  • If you do not want the user to be redirected to the current page post sign in, use redirectToAuth({redirectBack: false})

Showing sign up by default#

The login screen shows the sign in UI by default, to change that, you can set the folowing config:

import SuperTokens from "supertokens-auth-react";import EmailPassword from 'supertokens-auth-react/recipe/emailpassword';import Session from 'supertokens-auth-react/recipe/session';
SuperTokens.init({    appInfo: {        apiDomain: "...",        appName: "...",        websiteDomain: "..."    },    recipeList: [        EmailPassword.init({            signInAndUpFeature: {                defaultToSignUp: true            }        }),        Session.init({ /* ... */ })    ]});
