How to validate POST request body using `zod` to ensure typesafety (for pages router API endpoints)

insertroutename.ts

const createUserRequestSchema = z.object({
  name: z.string(),
  email: z.string().email(),
})

type CreateUserRequestBody = z.infer<typeof createUserRequestSchema>

export default async function handler(
  req: NextApiRequest,
  res: NextApiResponse
) {
  if (req.method === 'POST') {
    let requestBody: CreateUserRequestBody

    try {
      requestBody = createUserRequestSchema.parse(req.body)
    } catch (error) {
      if (error instanceof ZodError) {
        return res.status(400).json({ error: error.message })
      }
      return res.status(400).json({ error: 'Invalid types provided in request body' })
    }

    const { name, email } = requestBody;

    // Prisma code here
    // prisma.create(name, email, etc)
}
