Handling Typescript Errors and Runtime Type Checking with Prisma and Zod (🏁 solution)

👨‍💼 Looking good! Now we can more safely change our database schema and the query! You will want to make sure to add a test to this page to help catch mistakes, but we're much better off having this validation in place.

🦉 Parsing data at runtime can be a potential issue if there are many records to parse and validate. However that's unlikely to be an issue here with a limit of 50 records. That said, we could definitely strip this in production with something like this:

const result = UserSearchResultsSchema.safeParse(rawUsers)
const result =
	ENV.MODE === 'production'
		? ({
				success: true,
				data: rawUsers as z.infer<typeof UserSearchResultsSchema>,
			} as const)
		: UserSearchResultsSchema.safeParse(rawUsers)
if (!result.success) {
	return json({ status: 'error', error: result.error.message } as const, {
		status: 400,
	})
}
return json({ status: 'idle', users: result.data } as const)

And we can turn that into a util function as well if we found ourselves wanting to do that a lot.
