 When doing `return { props: { dehydratedState: dehydrate(queryClient) } }` in Next.js, or `return json({ dehydratedState: dehydrate(queryClient) })` in Remix, what happens is that the `dehydratedState` representation of the `queryClient` is serialized by the framework so it can be embedded into the markup and transported to the client.
 
-By default, these frameworks only supports returning things that are safely serializable/parsable, and therefor does not support `undefined`, `Error`, `Date`, `Map`, `Set`, `BigInt`, `Infinity`, `NaN`, `-0`, regular expressions etc. This also means that you can not return any of these things from your queries. If returning these values is something you want, check out [superjson](https://github.com/blitz-js/superjson) or similar packages.

 If you are using a custom SSR setup, you need to take care of this step yourself. Your first instinct might be to use `JSON.stringify(dehydratedState)`, but because this doesn't escape things like `<script>alert('Oh no..')</script>` by default, this can easily lead to **XSS-vulnerabilities** in your application. [superjson](https://github.com/blitz-js/superjson) also **does not** escape values and is unsafe to use by itself in a custom SSR setup (unless you add an extra step for escaping the output). Instead we recommend using a library like [Serialize JavaScript](https://github.com/yahoo/serialize-javascript) or [devalue](https://github.com/Rich-Harris/devalue) which are both safe against XSS injections out of the box.
