Adding Extra Fields

Step 1: Front End#

Currently, your Sign-up form contains only email and password fields. But you might want to get more information from your customers on sign up. Let's see how you can extend the Sign-up form to fit your needs.

SuperTokens.init({    appInfo: {...},    recipeList: [        EmailPassword.init({            signInAndUpFeature: {                signUpForm: {                    formFields: [{                        id: "name",                        label: "Full name",                        placeholder: "First name and last name"                    }, {                        id: "age",                        label: "Your age",                        placeholder: "How old are you?",                    }, {                        id: "country",                        label: "Your country",                        placeholder: "Where do you live?",                        optional: true                    }]                }            }        }),        Session.init()    ]});
tip

Please refer to the auth-react reference API for more information about adding custom fields.

Step 2: Back End#

Add fields to SuperTokens init#

Now that you have added new fields to the front end you need to make sure that the backend will take them into account when your new users register.

Go back to where you have called the SuperTokens init function in your NodeJs application:

SuperTokens.init({    appInfo: {...},    supertokens: {...},    recipeList: [        EmailPassword.init({            signUpFeature: {                formFields: [{                  id: "name"                }, {                  id: "age"                }, {                  id: "country",                  optional: true                }]            }        }),        Session.init({...})    ]});

Handle form fields on successful Sign-up#

Have a look at the "handling post sign up" section.

caution

SuperTokens does not store custom form fields. You need to store them in your db post user sign up.
