vue3-toastify was shipping in the entry chunk of every single page — including those that never show a toast. A dynamic import composable moved it to a separate chunk that loads on first trigger, cutting 22KB from entry.js and 9KB from entry.css.
How a single inline await in our Vue composable was silently serializing all data fetching during server-side rendering, and how onServerPrefetch fixed it with zero architectural changes.
How we discovered that three redirect constant files were shipping 316KB of dead weight to every browser, and why moving them to server middleware with a database fallback cut our JavaScript bundle by a third.
We discovered that our image optimization pipeline was generating perfect srcset values that the browser completely ignored. The fix was a single HTML attribute we had been treating as optional for years.
We were burning full Vue Router navigation cycles just to fix slug URLs on product pages. Replacing router.replace() with history.replaceState() eliminated wasted re-renders, fixed broken SEO meta tags, and cut client-side canonicalization to a single DOM-free call.
Our monolithic Nuxt app kept crashing at the 2GB memory limit. We doubled to 4GB — twice the cost, same underlying problem. After five days of failed optimization attempts (streaming compression, Redis polling, SWR caching), we split the monolith into three standalone services. Each got its own 2GB allocation, total cost dropped, and the crashes stopped.
We added Arabic and Portuguese to our Nuxt i18n setup but blocked them from production. The problem? Sitemaps, hreflang tags, and crawlers didn't get the memo — generating thousands of wasted URLs, doubling API calls, and burning through serverless invocations.
A repeating radial-gradient that looked great in design turned my page into a laggy mess. Here is how I tracked it down and fixed it with an inline SVG data URI — zero visual difference, smooth 60fps scrolling.
How a simple destructuring pattern removed redundant translation objects from API responses, reducing cache storage and improving client performance.
How a seemingly correct cache key using url.hostname causes cache fragmentation between SSR and client requests, dramatically reducing cache hit rates in Nuxt/Nitro applications.
