Catch invalid route parameters before they hit your backend. Here's how to validate them client-side using Zod and Nuxt's definePageMeta.

Stop writing manual validation logic in every API route. Here are some utility functions that make Zod validation painless in Nuxt.

Wrangler 3+ removed the ability to easily emulate public R2 buckets locally. Here's a simple Nuxt server route workaround.
