Handle Event Hook

This function is called for various user actions. It can be used for logging, analytics or any side effect purposes (these are essentially fire and forget events).

ReactJS
Angular
Vue
Plain JavaScript
React Native

Note

You can use the supertokens-web-js SDK which exposes several helper functions that query the APIs exposed by the SuperTokens backend SDK.

You can refer to this example app as a reference for using the supertokens-web-js SDK.

Note

To use SuperTokens with React Native you need to use the supertokens-react-native SDK. The SDK provides session management features.

To add login functionality, you need to build your own UI and call the APIs exposed by the backend SDKs. You can find the API spec here

import Passwordless from "supertokens-auth-react/recipe/passwordless";
Passwordless.init({    contactMethod: "EMAIL", // This example works with any contactMethod    onHandleEvent: (context) => {        if (context.action === "PASSWORDLESS_CODE_SENT") {
        } else if (context.action === "PASSWORDLESS_RESTART_FLOW") {                    } else if (context.action === "SESSION_ALREADY_EXISTS") {            // called when a user visits the login / sign up page with a valid session            // in this case, they are usually redirected to the main app        } else if (context.action === "SUCCESS") {            let user = context.user;            if (context.isNewUser) {                // sign up success            } else {                // sign in success            }        }    },})
