How to use

Use the override config

See all the functions that can be overrided here

ReactJS

Note

To use SuperTokens with plain javascript you need to use the supertokens-website 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

You can refer to this blog post to know how this is done, the example uses social login but the same setup applies to other recipes as well.

Plain JavaScript

Note

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

import SuperTokens from "supertokens-auth-react";import EmailPassword from "supertokens-auth-react/recipe/emailpassword";
SuperTokens.init({    appInfo: {        apiDomain: "...",        appName: "...",        websiteDomain: "..."    },    recipeList: [        EmailPassword.init({            override: {                functions: (originalImplementation) => {                    return {                        ...originalImplementation,
                        // we will only be overriding what happens when a user                        // clicks the sign in button.                        signIn: async function (input) {                            // TODO: some custom logic
                            // or call the default behaviour as show below                            return originalImplementation.signIn(input);                        },                        // ...                        // TODO: override more functions                    }                },                emailVerification: {                    functions: (originalImplementationEmailVerification) => {                        return {                            ...originalImplementationEmailVerification,                            isEmailVerified: async function (input) {                                // TODO: some custom logic
                                // or call the default behaviour as show below                                return originalImplementationEmailVerification.isEmailVerified(input);                            },                            // ...                            // TODO: override emailverification functions here                        }                    }                }            }        })    ]});

• originalImplementation and originalImplementationEmailVerification are objects that contain functions that have the original implementation for this and the email verification recipe. They can be used in your functions as a way to use the SuperTokens' default behaviour.
• In the above code snippet, we override the signIn function of this recipe. This means that when the user clicks the sign in button in the UI, your function will be called with the relevant input object.
• Likewise, we override the isEmailVerified function for the email verification recipe. This means that when a user signs in / up, and if email verification is in "REQUIRED" mode, then your function will be called to check if that user's email is verified or not.
