2. Backend config

1) Install supertokens package#

npm i supertokens-node

2) Create a configuration file (config/supertokensConfig.js)#

  • Create a config folder in the root directory of your project.
  • Create a supertokensConfig.js inside the config folder.
  • An example of this file can be found here.

3) Create a backend config function#

/config/supertokensConfig.ts

import ThirdParty from 'supertokens-node/recipe/thirdparty';
import Session from 'supertokens-node/recipe/session'

function getBackendConfig() {
  return {
    framework: "awsLambda",
    supertokens: {
      connectionURI: "",
      apiKey: "",
    },
    appInfo: {
      // learn more about this on https://supertokens.com/docs/thirdparty/appinfo
      appName: "<YOUR_APP_NAME>",
      apiDomain: "<YOUR_API_DOMAIN>",
      websiteDomain: "<YOUR_WEBSITE_DOMAIN>",
      apiBasePath: "/auth",
      websiteBasePath: "/auth"
    },
    recipeList: [
      ThirdParty.init({
        signInAndUpFeature: {
          // We have provided you with development keys which you can use for testing.
          // IMPORTANT: Please replace them with your own OAuth keys for production use.
          providers: [{

When you want to generate your own keys, please refer to the corresponding documentation to get your client ids and client secrets for each of the below providers:

Google
  • Generate your client ID and secret by following the docs here
  • Set the authorisation callback URL to <YOUR_WEBSITE_DOMAIN>/auth/callback/google
Github
  • Generate your client ID and secret by following the docs here
  • Set the authorisation callback URL to <YOUR_WEBSITE_DOMAIN>/auth/callback/github
Facebook
  • Generate your client ID and secret by following the docs here
  • Set the authorisation callback URL to <YOUR_WEBSITE_DOMAIN>/auth/callback/facebook
Note

Make sure to enable https to be able to use the test users of the Facebook app. On http://localhost, the login flow can be verified only with the app's admin user.

Apple
  • Generate your client ID and secret by following this article
  • Set the authorisation callback URL to <YOUR_API_DOMAIN>/auth/callback/apple. Note that Apple doesn't allow localhost in the URL. So if you are in dev mode, you can use the dev keys we have provided above.
