Performance

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 Redis cache kept dropping TLS connections, taking down the entire caching layer. After a misleading benchmark nearly sent us in the wrong direction, we migrated to PostgreSQL — same performance, zero drops, one less service to manage.

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.

How replacing API response proxying with 307 redirects to signed CDN URLs eliminated origin bandwidth costs and removed an entire class of streaming bugs.

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 to implement Stale-While-Revalidate caching that adapts based on user type and endpoint sensitivity. B2B users get fresh stock data while anonymous visitors enjoy faster cached responses.

How we squeezed 6x more cache entries into a 1GB Redis instance using gzip compression, while maintaining type safety and sub-millisecond overhead.

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.

How we replaced slow key-iteration cache clearing with instant timestamp-based invalidation while preserving SWR performance.

A deep dive into PostgreSQL pagination inconsistencies and the importance of deterministic sorting in complex queries that was driving our users crazy

While optimizing a Nuxt 3 project, I discovered excessive automatic prefetching was driving up Vercel bandwidth. Disabling prefetch globally brought costs and network overhead way down.

I inherited a Nuxt 3 project that was costing over $50/day in Vercel bandwidth. The culprit? A single wildcard import pulling in the entire Font Awesome library. Here’s how I found and fixed it.

From sluggish red Lighthouse scores to blazing green: The lazy loading technique that cut our initial bundle by 92% and boosted performance by 47%

How we built a sophisticated multi-layered search system that understands user intent, handles typos, and delivers relevant results across 9 languages using PostgreSQL, TypeScript, and smart algorithms

Simple changes to fix Largest Contentful Paint and Cumulative Layout Shift in Nuxt 3. Preconnect hints, image dimensions, and the hidden performance killers.

Three SQL anti-patterns that were killing our search performance, and the CTE optimizations that fixed them.
