Learn how Nuxt 3's useAsyncData composable fetches data once on the server, serializes it into HTML, and reuses it during client navigation to avoid duplicate requests and flicker.
Learn how to identify and fix hydration mismatch errors in Nuxt.js, ensuring your server-rendered HTML aligns with client-side Vue state for better performance and SEO.
When Nuxt pages misbehave, middleware misconfiguration is a common culprit. This guide walks through symptoms, causes, a diagnostic checklist, concrete fixes, and verification steps to get your middleware running smoothly.
Protect Nuxt 3 routes with a minimal server‑side middleware that checks an HTTP‑only cookie. Learn the requirements, design, data boundaries, operational checks, failure modes, and when to change the approach.
useAsyncData Timeout Configuration Missing Nuxt 3’s useAsyncData provides an abort option that returns an AbortSignal , yet the framework does not automatically forward this signal to the fetcher function. As a result, developers must manually pass the signal to the HTTP client to allow cancellation when a component unmounts or a route changes. Additionally,
Goal Select a Nuxt 3 routeRules caching strategy for dynamic pages whose content changes on a fixed schedule, balancing origin load, SEO, and acceptable staleness. Constraint Nuxt 3.8+ lists experimental swr with a default TTL of 3600 seconds and isr requiring an explicit ttl . Both depend on a Nitro-compatible edge platform; self-hosted Node.js deployments
Nuxt.js uses a universal rendering approach where the server generates initial HTML and the client hydrates the state to enable Vue.js reactivity. This process relies on a serialized state object injected into the HTML to ensure consistency between the server-rendered DOM and the client-side Vue instance. When components rely on dynamic data via asyncData or
When auditing a Nuxt 3 application, some configuration entries that were intended for server‑only use appear in the generated client bundle, suggesting they are being treated as public runtime config. The goal is to understand why values without the NUXT_PUBLIC_ prefix are being included in the client‑side JavaScript and to confirm whether they are actually
Stale-While-Revalidate Behavior in Nitro Nuxt utilizes the Nitro server engine to implement route-level caching via routeRules . When configuring a route with swr (stale-while-revalidate), the server is designed to serve a cached response immediately while triggering a background refresh if the TTL has expired. Granular Invalidation Constraints While the swr
