I just want to do `const config: SuperTokensConfig = { appInfo: ..., ...}` and have typescript enforce type correctness of the config

the types are not exposed by the frontend SDK unfortunately. That beignn said, you can add your config directly in supertokens.init(config)

And then if the implicit type of `config` is wrong, TS will complain

it's a bit hacky, but you could do something like:
```ts
const config: Parameters<typeof SuperTokens.init>[0] = {.... };
```

fancy, I didn't know TS supported reflection like that

thanks for the pointers and affirming that I'm not missing something simple!

happy to help 🙂 TS can do pretty powerful stuff (to the point where it gets really hard understand :D)
