SuperTokens is an open source authentication solution offering features like: Different types of login: Email / password, Passwordless (OTP or Magic link based).

And when I test it:
```sh
$ node auth.js
node:internal/errors:466
    ErrorCaptureStackTrace(err);
    ^

Error [ERR_MODULE_NOT_FOUND]: Cannot find package '@middy/core' imported from /home/dsaghliani/Projects/supertokens-demo/server-lambda/auth.js

}

You might wanna try `npm install --save @middy/core`

God, that makes so much sense. Why didn't I think of that? Sorry, I'm still wrapping my head around Node and NPM.
