First page + auto routing
Create a Nuxt app with `pages/index.vue` and `pages/about.vue`. Add links between pages and verify route generation works without manual router setup.
Frontend / Knowledge library
Nuxt (nuxt)
vue framework for full-stack web apps
Why learn Nuxt (nuxt)?
Nuxt gives Vue teams a batteries-included way to build SEO-friendly, full-stack apps (pages, routing, data fetching, server APIs, rendering modes, and deployment) without wiring everything manually.
Where it came from
2016: Nuxt.js started to simplify Vue server-side rendering. 2018: Nuxt 2 expanded conventions, modules, and static generation workflows. 2021: Nuxt 3 development introduced the Nitro server engine and modern architecture. 2022: Nuxt 3 became stable with Vue 3, Vite, and composable-first patterns. 2023–2024: Nuxt 3.x refined layers, rendering controls, tooling, and ecosystem modules.

Build your understanding
Work through these exercises in order. Try the task before opening a reference.
- Create a Nuxt app with `pages/index.vue` and `pages/about.vue`. Add links between pages and verify route generation works without manual router setup.
- Add `server/api/posts.ts` returning mock posts. In `pages/index.vue`, use Nuxt async data fetching so content is available on first render.
- Configure `routeRules` so `/blog/**` uses SWR caching and `/admin/**` stays SSR-only. Explain why this split helps performance and freshness.
- Create a base layer with shared components and config, then extend it from a second Nuxt app. Confirm the child app can override one component cleanly.
- Implement route middleware that redirects unauthenticated users from `/dashboard` to `/login`, while preserving intended destination for post-login return.
More ways to practice
Server API + SSR fetch
Add `server/api/posts.ts` returning mock posts. In `pages/index.vue`, use Nuxt async data fetching so content is available on first render.
Hybrid rendering by route
Configure `routeRules` so `/blog/**` uses SWR caching and `/admin/**` stays SSR-only. Explain why this split helps performance and freshness.
Reusable layer
Create a base layer with shared components and config, then extend it from a second Nuxt app. Confirm the child app can override one component cleanly.
Auth-aware middleware
Implement route middleware that redirects unauthenticated users from `/dashboard` to `/login`, while preserving intended destination for post-login return.

Catalog research notes
- Nuxt 3.x continues improving startup/build speed and TypeScript DX.
- Hybrid rendering controls (SSR/SSG/SWR via route rules) are more production-friendly.
- Nuxt DevTools and module tooling have matured for faster debugging.
- Nitro deployment targets remain a core strength for Node and edge/serverless runtimes.

Real World Example
Unified Inventory API Integration
E-commerce retailers managing fragmented inventory data across multiple legacy warehouse systems.
The business problem
High latency and maintenance overhead caused by managing disparate API endpoints and inconsistent data formats for real-time stock lookups.
How this topic solves it
Utilizing Nitro's filesystem routing and built-in storage layer to create a unified, server-side abstraction layer that aggregates inventory data into a single, performant endpoint.
- Define a new server route in the server/api directory to act as the inventory aggregator.
- Implement the logic to fetch data from legacy warehouse systems using server-side utilities.
- Configure the built-in storage layer to cache aggregated results, reducing redundant external API calls.
- Expose the unified endpoint to the frontend, ensuring consistent data structures for the client.
Shows how the Nitro server acts as a central hub between the client and legacy systems.
Requests stock data
Aggregates and caches data
Stores cached inventory
Source of truth
- Frontend App → GET /api/inventory → Nitro API Route
- Nitro API Route → Check cache → KV Storage
- Nitro API Route → Fetch fresh data → Legacy Systems
Implementation example
This code demonstrates creating a server-side route that fetches data from a legacy source and stores it in the built-in storage layer for subsequent requests.
export default defineEventHandler(async (event) => {
// Fetch data from legacy system via server-side utility
const data = await $fetch('/api/warehouse-legacy');
// Use storage layer to cache the result for performance
await useStorage().setItem('inventory:cache', data);
return data;
});Expected business outcome
A simplified frontend architecture that interacts with a single, reliable API, resulting in faster page loads and reduced load on legacy backend systems.
Limitations and checks
The abstraction layer creates a single point of failure; if the aggregator logic fails, all inventory lookups are blocked. This can be checked by monitoring the server-side error logs and implementing custom error handlers.
