  Deploying SuperTokens with React and NodeJS on Vercel by@supertokens.io
  In this tutorial, you'll learn how to add SuperTokens authentication to your React and NodeJS application and deploy it on Vercel. This tutorial will help you get started with SuperTokens and deploy your application on the serverless platform. We are deploying our backend as a standalone express app, and not with `/pages/api` serverless functions that Vercel provides. We will be exposing the API's entry point via an `index.js` file in this folder. We must set the values of `apiDomain` and `websiteDomain` dynamically.
  We also have a blog post on how to integrate email password + social login with express and react, if that is what you are looking for.
  Create an api folder. This folder will contain the API logic that we can deploy on Vercel. We will be exposing the API's entry point via an index.js file in this folder.
  Note: We are deploying our backend as a standalone express app, and not with /pages/api serverless functions that Vercel provides. If you want to deploy using /pages/api, then you can check out our nextJS framework integration guide that's within the recipe guide.
  We can use window.location.origin it to get the currently loaded URL and set those to the apiDomain and websiteDomain. This way, even if the inspect URL keeps on changing, it will still point to the current domain.
  With the backend and frontend of your application code updated, create a vercel.json file in the root directory of your application which will instruct Vercel to push all traffic on /api/* path to our express backend server:
