Next.js vs Vite in 2026: What you should actually use

Next.js vs Vite in 2026: What You Should Actually UseAs we approach 2026, the JavaScript ecosystem continues to evolve at a rapid pace. Two of the most prominent tools for building modern web applications are Next.js and Vite. Both have matured significantly, offering developers powerful features for performance, scalability, and developer experience. However, choosing between them depends on your project's specific requirements. In this article, we’ll dive deep into the technical aspects

Zod v4 vs Valibot: I Benchmarked Both for My AI SaaS and Here's What I Found

I validate a lot of data. Every Claude API call I make returns structured JSON, every Stripe webhook hits a schema check, every user form submission runs through a parser. At scale, this adds up — and I started noticing my edge functions were ballooning in bundle size and my LLM output parsing was adding 10-20ms of latency I couldn't explain.So I benchmarked Zod v4 (just dropped) against Valibot 1.x for three real workloads from my AI SaaS. Here's what I found. The SetupAll benchmarks ran o

React 19 use() Hook in Production: Suspense Data Fetching Without useEffect

The use() hook landed in React 19 and immediately changed how I think about data fetching. Not because it's magic — but because it finally makes Suspense-based data fetching feel like something you'd actually ship to production.Most articles show you use(promise) inside a toy component and call it a day. This one covers what happens when real users hit your app: race conditions, error boundary placement, streaming with RSC, caching strategies, and the gotchas that will bite you if you're not pay

"I Texted My Localhost From the Train — Claude Code Fixed the Bug Before I Got Home"

Last Tuesday I was on the train home when a Slack message came in: "prod build is broken, can you look?"I didn't have my laptop open. I didn't want to SSH from my phone. But I had something else — a Telegram bot connected to my localhost machine at home.I typed: "launch claude code in ~/projects/api-server, fix the failing build"By the time I walked through my front door, the fix was committed.That's not how localhost is supposed to work. But here we are. The Idea That Sounded CrazyFor mont

Using Generators to Simplify Complex Async Workflows

Using Generators to Simplify Complex Async Workflows: A Comprehensive Guide IntroductionThe JavaScript ecosystem has witnessed significant evolution in handling asynchronous workflows. With the introduction of Promises and async/await syntax, managing async operations has become more straightforward compared to older methods, such as callback functions. However, JavaScript generators represent a potent yet under-utilized tool for simplifying complex async workflows, offering control o

Node.js 24.14.1 LTS Production Guide — Native TypeScript, Explicit Resource Management, OpenSSL 3.5 Post-Quantum Crypto, npm 11 65% Faster

On April 1, 2026, Node.js 24.14.1 was officially promoted to Active LTS. Codenamed "Jod," this release comes with long-term support through April 30, 2028, while Node.js 22 LTS ("Jubilee") moves into Maintenance. This is not just another version bump. Native TypeScript execution that eliminates the build step, using/await using declarations that structurally solve resource leaks, OpenSSL 3.5 with post-quantum cryptography, and npm 11 with 65% faster installs — there's a reason this is being call

TypeScript 5.5 Inferred Type Predicates — Stop Writing `x is T` By Hand

Before TypeScript 5.5, writing a type guard meant doing the compiler's job for it. You'd write the runtime check, then manually annotate the return type to tell TypeScript what it already could have figured out:// Pre-5.5: you write the logic AND the annotationfunction isString(x: unknown): x is string { return typeof x === 'string';}function isNonNull&lt;T&gt;(x: T | null): x is T { return x !== null;}That x is T annotation is a lie waiting to happen. Refactor the function body, forget to upd

Next.js 14 Server Actions: The Patterns Junior Devs Always Get Wrong

Next.js 14 Server Actions: The Patterns Junior Devs Always Get WrongNext.js 14 introduced Server Actions, a powerful feature that allows developers to execute server-side logic directly from client components. While Server Actions simplify many aspects of modern web development, they’re also prone to misuse—especially by junior developers. Over the past few months, I’ve noticed recurring patterns of mistakes that lead to bugs, poor user experiences, and technical debt. In this article, I’l

Vercel AI SDK useChat in Production: Lessons From 30 Days of Real Traffic

The Vercel AI SDK useChat hook looks simple in demos. In production, it's a different story.After running it under real traffic for 30 days — streaming Claude responses, handling errors, managing session state — here's what I learned. The Hidden Footgun: Message State on Re-renderuseChat holds messages in local state. On every re-render, new message objects are created. If you're passing messages to child components without memoization, you'll trigger expensive re-renders on every token.Fix

Next.js 15 + Claude API Streaming: Build a Real-Time AI Chat Interface From Scratch

Most Next.js AI tutorials reach for the AI SDK and skip over what's actually happening. That's fine until something breaks and you don't know why.This guide wires Claude's streaming API directly into Next.js 15's App Router with zero AI SDK dependency. By the end you'll have a production-quality streaming chat with proper backpressure, error handling, and a React UI that doesn't flash or stutter. What We're BuildingPOST /api/chat — streams Claude's response as Server-Sent EventsReact useCha

One Practical Way to Use useEffect 🎯

Let’s talk about a small UX detail that can make a big difference.Imagine your application has a modal. The user opens it… but the background page is still scrollable. Suddenly, the focus is gone, the UI feels messy, and the experience isn’t as pleasant as it should be.This is a surprisingly common issue and a perfect example of where useEffect can help us clean things up and improve the user experience.In this post, I’ll show a simple and effective way to prevent background scrolling when a mod

Frontend Performance That Actually Moves the Needle

In this article we'll cover why Lighthouse scores alone don't tell the full story, what metrics actually matter at scale, how real user monitoring changes the way you think about performance, and the optimizations that have the most impact on platforms serving millions of users.Lighthouse is a great tool. I'm not here to tell you to ignore it. But I've seen teams chase a perfect Lighthouse score while their real users were experiencing 4-second load times on mid-range android devices with a 4G c
