Which UI do you use?

Custom UI

Pre built UI

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

// this goes in the auth route config of your frontend app (once the pre built UI script has been loaded)


(window as any).supertokensUIPasswordless.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 === "SUCCESS") {
            if (context.createdNewSession) {
                let user = context.user;
                if (context.isNewRecipeUser && context.user.loginMethods.length === 1) {
                    // sign up success
                } else {
                    // sign in success
                }
            } else {
                // this is during second factor login
            }
        }
    },
})

Angular

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 === "SUCCESS") {
            if (context.createdNewSession) {
                let user = context.user;
                if (context.isNewRecipeUser && context.user.loginMethods.length === 1) {
                    // sign up success
                } else {
                    // sign in success
                }
            } else {
                // this is during second factor login
            }
        }
    },
