• Passkeys in Production: What I Wish I Knew Before Replacing Passwords 5/8/2026 Passkeys look simple in the WebAuthn demo. They get strange the moment you handle a user with two laptops, a stolen phone, a Bitwarden subscription, and a corporate device that blocks iCloud Keychain. Here is what shipping passkeys to real users actually looks like in 2026.
• JavaScript Async Lifetimes: The Leak You Have and Probably Do Not Know About 5/7/2026 Promise.all does not cancel sibling tasks when one fails. Your async code is likely leaking database connections, keeping fetches alive after unmount, and holding ports open through process exits. ES2026 finally gives you the primitives to fix this without a library. Here is how.
• AI SDK v6: The Practical Guide to Shipping AI Features Without Vendor Lock-In (2026) 4/20/2026 The Vercel AI SDK v6 is the easiest way to add AI features to a product in 2026 without marrying one model provider. Here is how it works, what actually changed in v6, and the patterns that matter when you are shipping real features rather than demos.
• REST vs GraphQL vs tRPC: What I Actually Use and Why in 2026 4/16/2026 GraphQL enterprise adoption grew 340% since 2023. tRPC is projected to power 60% of new TypeScript full-stack apps by 2027. REST is still what most production systems actually run on. The comparison articles give you feature tables. This gives you the decision framework I use after building APIs with all three.
• ES2026 Is Here: The JavaScript Features That Actually Change How You Write Code 4/13/2026 ES2026 ships the Temporal API, explicit resource management with using and await using, Error.isError(), and Array.fromAsync. Some of these solve problems you have been working around for years. Others are subtle but eliminate real classes of bugs. Here is what each one does and when it matters.
• TypeScript 7.0 and Project Corsa: The Go Rewrite That Changes Everything 3/30/2026 Microsoft just shipped TypeScript 6.0 as the final JavaScript-based release and is finishing the Go-native rewrite for TypeScript 7.0. The benchmarks are staggering: 10x faster builds, 3x lower memory usage, and sub-100ms watch restarts. Here is what Project Corsa means for your projects, what breaks, and exactly how to prepare for the biggest TypeScript change since version 1.0.
• Local-First Software Is Winning: A Developer Guide to Building Without the Cloud 3/28/2026 The cloud made everything possible. It also made everything dependent. Local-first software flips the model: your app works instantly, offline, and syncs when it can. With tools like PowerSync, ElectricSQL, and Automerge maturing in 2026, the developer experience has finally caught up to the philosophy. Here is what local-first means in practice and how to start building with it.
• How to Build a Discord Bot with Bun and TypeScript in 2026 3/27/2026 Most Discord bot tutorials still use Node.js and JavaScript. This guide takes a modern approach with Bun and TypeScript, covering everything from project setup to slash commands to deployment. Bun starts in under 15ms, runs TypeScript natively, and installs packages faster than you can read this sentence.
• TanStack Start vs Next.js in 2026: Should You Actually Switch? 3/26/2026 Next.js has been the default full-stack React framework for years. TanStack Start is the first real challenger that made me reconsider. Here is an honest comparison based on building with both in production, covering routing, data loading, performance, and the tradeoffs nobody tells you about.
• Learning to Code in 2026: What Actually Matters When AI Writes Code for You 3/24/2026 AI can write functional code in seconds. The "computer programmer" job title is declining by 27 percent. Every tech influencer has an opinion on whether coding is dead. Here is what nobody tells you: learning to code in 2026 is more valuable than ever, but what you need to learn has fundamentally changed. The path that worked five years ago will waste your time today.
• AI-Generated Code Is Creating a Technical Debt Crisis Nobody Is Auditing 3/20/2026 Forty-one percent of all new code is now AI-generated. Most of it ships without meaningful review. The result is a new category of technical debt that traditional tools cannot detect and most teams are not even looking for. Here is a practical framework for auditing your codebase before it catches up with you.
• Context Engineering in 2026: The Skill That Actually Makes AI Coding Work 3/19/2026 The industry spent 2024 obsessing over prompt engineering. In 2026, the developers getting the best results from AI coding agents have quietly moved on to something different. Context engineering is about designing what the model sees, not just how you ask. Here is why it matters and how to actually do it.
• Spec-Driven Development in 2026: The Future of AI Coding or Waterfall 2.0? 3/18/2026 Everyone is talking about spec-driven development. GitHub launched Spec Kit with 72k stars. AWS built Kiro around it. But some developers say it is just Waterfall wearing a new hat. I tried it on a real project and here is what I actually think.
• Vite 8, Rolldown, and Oxc: Rust Is Taking Over the JavaScript Toolchain 3/12/2026 Vite 8 beta runs on Rolldown, a Rust-powered bundler that replaces both esbuild and Rollup under the hood. The benchmark numbers are almost offensive. Here is what changed, why it matters, and whether you should upgrade today.
• Bun Compatibility in 2026: What Actually Works, What Does Not, and When to Switch 3/11/2026 "Is Bun production ready?" is the wrong question. The right question is ready for what. This is the compatibility map -- by Node.js API, npm package type, and Next.js use case -- so you can make a real decision for your specific stack.
• Claude Code vs Cursor vs GitHub Copilot: The 2026 AI Coding Tool Showdown 3/10/2026 The AI coding tool landscape flipped in 2026. Claude Code went from zero to the number one tool in eight months.

• The React Compiler Is Here: Say Goodbye to useMemo and useCallback 3/7/2026 React Compiler hit v1.0 in late 2025 and it changes how we think about React performance. No more manually wrapping functions in useCallback or values in useMemo. The compiler handles it. Here is what actually changed and how to start using it today.
• TypeScript Without a Build Step: Native Type Stripping in Node.js 3/7/2026 Node.js can now run TypeScript files natively. No ts-node, no tsc, no esbuild. Just node index.ts and you are done. Here is what type stripping actually means, why it matters, and when you still need a proper build step.
• Cloudflare Vinext: The AI-Built Next.js Replacement That Changes Everything 3/4/2026 Cloudflare built a drop-in Next.js replacement called vinext in under a week, using AI to write nearly every line of code. It builds 4.4x faster, ships 57% smaller bundles, and deploys to Cloudflare Workers with one command. But the most important story here is not the framework itself.
• Bun vs Node.js: Is It Time to Switch in 2026? 2/23/2026 Bun has been making noise since it launched, promising faster startup times, built-in TypeScript support, and a batteries-included runtime. But is it actually ready to replace Node.js for real projects in 2026? I ran the benchmarks, migrated a side project, and here is what I found...
