Do you know what the Circle (○) and Lambda (λ) symbols mean in Next.js build logs? Ensure you aren't accidentally making every page dynamic.
ISR works perfectly on Vercel, but fails on AWS/Docker. Let's dig into the file system cache trap and how to solve it.
I tried to save money by deploying to AWS S3 instead of Vercel, but ended up with a broken site. I share the three nightmares of Static Export (Image Optimization, API Routes, Dynamic Routing) and how to fix them.
I share how I created a maintenance nightmare by passing props down 5 levels. Learn why Prop Drilling kills productivity and how to escape using Context API, Component Composition, and Zustand.
Imagine a user clicking 'Checkout', logging in, and then landing on the Home page instead of the Checkout page. They will leave. I share how detailed redirect logic recovered sales, and how to prevent Open Redirect vulnerabilities during implementation.

Postmortem purpose and writing method
Users rage-quit my shopping app because hitting 'Back' reset their scroll position. Here's how I fixed Scroll Restoration in Next.js SPA.
How closures referencing outdated values caused bugs in my React app, and how I fixed them.
Running a service means failures will happen. Reading Google's SRE book made me realize that operations is a high-level engineering problem, not just toil. I walk through how the concepts of SLI, SLO, and Error Budget shift your mindset from firefighter to architect.
