Introduction

Data fetching is one of the most common challenges developers face when building modern web applications. While it might seem straightforward at first, managing server state quickly becomes complex when you need to handle caching, background updates, pagination, and error states. This is where TanStack Query (formerly React Query) comes in—a powerful library that transforms how we think about server state management.

In the previous post, we explored what Nitro plugins are and why they’re one of Nitro’s most powerful features. In this tutorial-focused follow-up, we’ll build real Nitro plugins step by step — the kind you’d actually use in production.

By the end, you’ll know how to create plugins for:

• Request logging
• API key authentication
• Response caching
• Feature flags and runtime configuration

All examples use TypeScript and work in Nuxt + Nitro or standalone Nitro apps.

Routing has always been one of those “it works… until it doesn’t” parts of web development. As applications grow, routes become harder to reason about, parameters drift out of sync, and refactors turn into a game of whack-a-mole.

TanStack Router was created to solve exactly that problem.

Built with type safety first, TanStack Router flips the traditional routing model on its head. Instead of hoping your routes, params, loaders, and links line up, the router guarantees they do—at compile time.

In this post, we’ll explore what makes TanStack Router different, why it matters, and how to use it effectively in real-world applications.
